Leuze electronic 3 Operating principle 3.1 Generation of 2D profiles Light section sensors work according to the triangulation principle. Using transmission optics a laser beam is expanded to a line and aimed at an object. The light remitted by the object is received by a camera, which consists of receiver optics and the CMOS area detector. Figure 3.1: Light section sensor design Depending on the distance of the object the laser line is projected to a different position on the CMOS planar detector as shown in figure 3.1. By means of this position the distance of the object can be calculated. +X -X Z -Y CMOS planar detector Receiving optics Laser with expansion optics The zero point of the coordi- nate system is the intersection of optical axis and front edge of the housing.

15 TNT 35/7-24V 3.2 Limits of light section sensors 3.2.1 Occlusion The detection of high and wide objects from just one point poses the particular problem that depending on the object contour, parts of the object may be obscured by others. This effect is called occlusion. The figure 3.2 illustrates the problem: Figure 3.2: Occlusion -Y Z +X -X Laser occlusion Receiver occlusion In the red areas the laser does not strike the object. Thus it is not possible to determine any data here. The receiver does not "see" any object contours in the red area because they are obscured by the upper right edge of the object. When the object is shifted to the left the object con- tour will still be detected by the laser but the laser line does not lie within the receiver's field of view at that point, and therefore no measurement values can be detected.

Leuze electronic Possible measure against laser occlusion • Using multiple light section sensors with rotated viewing direction. In the application example on the right you can clearly see that the fields of vision of the three sensors complement each other and merge. The first of the sensors is operated as a master, the two others are cascaded (see "Cas- cading" on page 22). This reliably prevents mutual interference of the sensors. Possible measures against receiver occlusion • Alignment of the objects so that all profile data to be detected are visible to the receiver. Or: • Installing a second sensor featuring a viewing direction rotated by 180° about the z-axis so that the objects can be viewed from 2 sides. In the example to the right, the left sensor detects the profile data on the left side of the product, and the right sensor the profile data on the right side. In this situation the second sensor is then cas- caded. See "Cascading" on page 22. Y

17 TNT 35/7-24V 3.2.2 Minimum object size The length of the laser line in X direction is variable and depends on the distance in Z direc- tion. However, always the same number of measurement points is measured. The measure- ment points on the object in the detection field are crucial for detecting the object. This implies that the minimum object size (i.e., the smallest detectable object) in the X direc- tion increases with the distance in the direction of Z. Small objects can be recognized better in the short range. Due to the triangulation measurement principle the reflected laser beam strikes the CMOS receiver in varying angles depending on the object distance. As a consequence, the minimum object size in Z-direction also increases with distance. The figure 3.3 shows this relation: Figure 3.3: Typical minimum object size LRS 36… 0 1 2 3 4 5 6 7 200 300 400 500 600 700 800 X Z Object distance in Z direction [mm] Typical minimum object size [mm]

An overview of the available types may be found in chapter 15.1

19 TNT 35/7-24V 4.1.3 Line Range Sensor - LRS Line Range Sensors are designed to perform proximity object detection along the laser line. Similar to a light barrier or a laser scanner, the sensor detects the presence of objects through scanning. With individual configuration, one sensor can be used to detect single or multiple objects. Specific performance characteristics • Configuration software LRSsoft • Data calculation and processing directly inside the sensor • Integrated PROFIBUS interface or 4 switching outputs • Up to 16 detection fields with logic oper- ation option • Detailed information on analysis windows, switching state and sensor status via Ethernet and PROFIBUS Typical areas of application • Situation and position control • Presence and absence detection of objects in defined areas • Height and width monitoring • Single or multiple track presence/absence detection on transport systems • Zero check of cases Single- or multi-track existence and absence check on conveying equipment Fill level monitoring

Leuze electronic 4.2 Operating the sensor 4.2.1 Connection to PC / process control Configuration For commissioning the light section sensors are connected to a PC via the Ethernet interface (see "Connection X2 - Ethernet" on page 41) and are then set using the configuration soft- ware supplied LRSsoft. Detection operation In detection operation, the LRS 36/6 is connected to the process control via its 4 switching outputs; the LRS 36/PB is connected to the process control via PROFIBUS. Alternatively, the LRS can be operated via the Ethernet interface on X2, see chapter 10 "Integrating the LRS in the process control (Ethernet)". Additional sensor information is then available. 4.2.2 Activation - laser on/off Via activation input InAct (pin 2 on X1), via PROFIBUS (master output 'uActivation' = 1) or the 'Ethernet Trigger' command, the laser and data transmission can be specifically switched on and off. Thus possible glares due to laser radiation can be prevented during time periods when no measurements are performed. Notice! The sensor is delivered ex works with the Activation Input Disregard setting. The possible activation sources (activation input, PROFIBUS activation and Ethernet activation) are ignored - the measurement function of the sensor is enabled. The activation function can be switched on via the configuration software. To do this, the Activation Input parameter must be set to Regard. The sensor then only measures if one of the activation sources is activated. If the sensor is waiting for activation, it displays !Act in the display. Figure 4.2: Activation input signal sequence p t Laser off Laser off Exposing and measuring Processing and transmitting Laser Activation input Pin 2 at X1 Output 10ms between 2 consecutive laser pulses in "Free Running" mode Axes: p = level, t = time approx. 14ms between laser pulse and as- sociated data output

21 TNT 35/7-24V The figure 4.2 shows the effect of the activation on laser and measurement value output in "Free Running" mode. 4.2.3 Triggering - Free Running The light section sensors can measure in two modes: • In "Free Running" operation the light section sensor determines measurement results with a frequency of 100Hz and outputs these continuously via the interface X2. • Alternatively, single measurements can also be carried out. For this purpose, the light section sensor requires a trigger signal at the trigger input (pin 5 on X1), a PROFIBUS trigger or the Ethernet Trigger command in detection mode (see chapter 10.3.4"Commands in detection mode" on page 89). When triggering via pin 5 at X1, note: - Triggering occurs on the rising edge. - The trigger pulse must be at least 100µs long. - Before the next trigger, the trigger cable must be on low-level for at least 1ms. - Activation must occur at least 100µs before the trigger edge. - The shortest possible time interval between two successive trigger edges is 10ms. Notice! Ex works, the LRS is set to Free Running (shown on display: fRun). In order for it to respond to signals on the trigger input, the operating mode must be set via the LRSsoft con- figuration software to Input Triggered (shown on display: Trig). Figure 4.3: Trigger input signal sequence p t A second trigger pulse before 10ms have elapsed has no effect Trigger time (rising edge) Laser Activation input Pin 2 at X1 Output (Ethernet) Data packets, approx. 1ms tfix approx. 14ms Trigger input Pin 5 at X1 Axes: p = level, t = time

Leuze electronic PROFIBUS trigger So that a measurement can be triggered on each PROFIBUS cycle, the PROFIBUS trigger of the LRS responds to a change of master output byte uTrigger. The control only needs to increment the trigger value in order to initiate a new measurement. The maximum trigger frequency is 100Hz. If triggering occurs during a measurement, the trigger signal is ignored, as is the case in the Free Running operating mode. 4.2.4 Cascading Figure 4.5: Cascading application example If several light section sensors are operated, there is the risk of mutual interference if the reflected laser beam of one sensor can be received by the receiver of another sensor at the time of reading. This can easily be seen in figure 4.5. Here three light section sensors are used to deter- mine the log thickness reliably from all sides. To prevent mutual interference the light section sensors can be operated cascaded: the exposure by the second sensor will be initiated following completion of the exposure by the first sensor. To achieve this, the cascading output of the first sensor must be connected to the trigger input of the second sensor. Up to 6 sensors can thus be operated cascaded. Trigger settings Sensor 1, or the master, can be operated in this case both triggered as well as continuously. All other sensors must be operated triggered. Cascading settings For all sensors except the last slave, the cascading output must be enabled via configuration software: Cascading Output: Enable. Laser Measurement value output Trigger input, pin 5 at X1 / not required Cascading output, pin 6 at X1 Sensor 1 / Master Laser Measurement value output Trigger input, pin 5 at X1 Cascading output, pin 6 at X1 Sensor 2 / 1. slave Laser Measurement value output Trigger input, pin 5 at X1 Cascading output, pin 6 at X1 Sensor 3 / 2. slave Figure 4.4: Signal sequence for cascading

23 TNT 35/7-24V Notice! In PROFIBUS operation, cascading only functions as described above via the InTrig and OutCas inputs/outputs at X1. In this case, the maximum detection rate of 100Hz is achieved. Make certain, however, that the input data of the PROFIBUS light section sensors are still transmitted in the same bus cycle; monitor the scan numbers if necessary. Alternatively, light section sensors with PROFIBUS can be selectively triggered in sequence. Master output 'uTrigger' of the sensor to be triggered is incremented on each PLC cycle; the master outputs of the other sensors do not change. The maximum detection rate of 100Hz is not achieved with this process. If multiple sensors are triggered in a PROFIBUS cycle, mutual interference may occur between the sensors if they are in the same visual field and the time between updating byte 'uTrigger' is shorter than the maximum exposure time (Exposure Time) of 1.3ms. 4.3 Detection functions LRS The LRS lets you carry out presence/absence and area monitoring with stable switching behavior and simple configuration. The sensor configuration is stored in the individual inspection tasks in the configuration software LRSsoft to reflect the requirements of different applications. 4.3.1 Inspection Task The LRS lets you operate with up to 16 individual inspection tasks, each of which may contain up to 16 rectangular analysis windows (AWs) that can be configured independently and that may overlap arbitrarily. 1-16 AWs can be defined for each inspection task. The results of the individual AWs may be combined via logic operations (AND, OR, NOT). A different logic operation can be defined for each of the 4 switching outputs Out1 to Out4. The selection of the inspection tasks is carried out: • via the switching inputs of connection X3 (inspection tasks 0-7 only) • via PROFIBUS • via LRSsoft (on a PC connected via X2) • via Ethernet (on a process control connected via X2) • via the control panel of the sensor beginning with firmware V01.40 4.3.2 Analysis Window (AW) The AWs are defined in the configuration software LRSsoft (see chapter 9.4 "Parameter settings/Parameters tab"). This software defines the spatial position, size and number of hit points to be detected for each AW. An evaluation is carried out only within the active AWs. Areas outside the sensor's field of vision are also not evaluated. An object is detected if the number of hit points in the AW reaches or exceeds an arbitrarily defined minimum value.

Leuze electronic Notice! The number of hit points does not necessarily correspond with the object size, since the num- ber of hit points is dependent on distance z. At near distance to the sensor (e.g., 300 mm), an object expanded in the X direction has nearly twice as many hit points as it does at a far distance (e.g, 600mm). If the object distance is the same, the number of hit points remains nearly constant. Analysis results The analysis results of individual AWs can be combined logically via the LRSsoft configu- ration software. The result of this logic operation is output via the switching states of the four switching outputs Out1-Out4 at X3 or PROFIBUS. Detailed evaluation results such as, e.g., the status of all AWs, the number of hit points and the state of the switching outputs are transmitted via Ethernet and can be queried via PROFIBUS. For more information please refer to chapter 10.

25 TNT 35/7-24V 4.3.3 Definition of AWs and analysis results In figure 4.6, 5 AWs are defined (blue rectangles). For each AW, a minimum of 5 hit points must be detected for the analysis result to be "1". If fewer hit points are detected, the analysis result is "0". Consider the example shown: • AW1: 8 hit points (on O1) result =1 • AW2: 4 hit points (on O2) result =0 • AW3: 1 hit points (on O2) result =0 • AW4: 3 hit points (on O2) result =0 • AW5: 11 hit points (on O4) result =1 Why is O2 not detected? O2 is not detected in AW2 because missing hit points are shadowed. For AW3, O2 is too far to the left. For AW4, the number of hit points to be detected would need to be lowered to 3. Why is O3 not detected? O3 is within AW3, but AW3 does not detect the object's upper edge and thus there is no detection. O3 is not detected within AW5 because, from the sensor's point of view, O4 is in front of it.

AW3 is used to check whether the container is empty. It is not empty if hit points are detected in AW3. Figure 4.7: Zero check of cases Z +X -X AW1 AW2 AW3

27 TNT 35/7-24V Single or multiple track presence/absence detection on transport systems In figure 4.8, as in figure 4.7, AW1 and AW2 are used to check whether a container of a certain height and width is located at a predefined position in the detection range. AW3 to AW8 are used to check whether and where objects are located in the container and what their height is. Figure 4.8: Single or multiple track presence/absence detection on transport systems 4.3.5 Creation of inspection tasks The settings necessary for the configuration of the AWs, the assignment of the AW states to the switching outputs and the configuration of general parameters such as operating mode, activation, cascading, detection range (FOV) etc. are carried out in LRSsoft, see chapter 9.4 "Parameter settings/Parameters tab" and chapter 9.7.

Leuze electronic Technical description LRS 29 TNT 35/7-24V 5.2 Mounting the LRS The light section sensors can be mounted in different ways: • By means of two M4x6 screws on the back of the device. • Using a BT 56 mounting device on the two fastening grooves. • Using a BT 59 mounting device on the two fastening grooves.

32 Technical description LRS Leuze electronic 5.3 Device arrangement 5.3.1 Selecting a mounting location In order to select the right mounting location, several factors must be considered: • The required resolution. This is a result of the distance and the resulting line length. • The permissible cable lengths between the LRS and the host system depending on which interface is used. • The display and control panel should be very visible and accessible. When selecting a mounting location, pay further attention to: • Maintaining the required environmental conditions (temperature, humidity). • Possible soiling of the optics covers on transmitter and receiver by discharged liquids, abrasion from cartons or packaging residues. • Lowest possible chance of damage to the LRS by mechanical collision or jammed parts. • Possible extraneous light (no direct sunlight or sunlight reflected by the measurement object). • The optimal perspective for detecting the relevant contours of objects, see chapter 3.2.1 "Occlusion". Attention, laser radiation! When mounting and aligning the LRS, avoid reflections of the laser beam off reflective sur- faces! Notice! The prevention of ambient light due to shielding of the sensor for example, ensures stable and precise measurement values. Secondary reflections of the laser line on reflective objects must be avoided as these can result in faulty measurements. The best measurement results are obtained when: - You adapt the operating mode (light/dark) to the application. - You do not measure high-gloss objects. - There is no direct sunlight. 5.3.2 Aligning the sensor The zero point of the sensor coordinate system is the intersection of optical axis and front edge of the housing. The general principle is that the light section sensor should be aligned so that the back of the sensor is aligned parallel to the conveying belt or measuring plane. Rotation along the Y-axis is not desirable. The figure 5.6 illustrates the problem:

Leuze electronic Technical description LRS 33 TNT 35/7-24V Figure 5.6: Alignment to the measuring plane A rotation of the sensor about the y-axis distorts the entire coordinate system, which the measurement values relate to. The sensor measures along the solid line in the right picture, however the measuring plane is located on the dotted line, and a measurement towards the conveying belt shown in gray would result in a tilted plane. When setting up an application it is therefore very important to ensure correct alignment and that the integrated alignment aid on the display is used. 5.4 Attach laser warning sign Attention Laser! Observe the safety notices in chapter 2. It is essential that you attach the stick-on label (laser warning signs and laser beam exit symbol) supplied with the light section sensor to the light section sensor! If the signs would be concealed as a result of the mounting situation of the LRS, attach the signs in the vicinity of the LRS such that reading the signs cannot lead to looking into the laser beam! When installing the LRS in North America, also attach the stick-on label saying "Complies with 21 CFR 1040.10" 5.5 Cleaning Clean the optics cover of the LRS with a soft cloth after mounting. Remove all packaging remains, e.g. carton fibers or styrofoam balls. In doing so, avoid leaving fingerprints on the optics cover of the LRS. Attention! Do not use aggressive cleaning agents such as thinner or acetone for cleaning the device. +X -X Z -Y -X +X Z -Y

Leuze electronic 6 Electrical connection The light section sensors are connected using variously coded M12 connectors. This ensures unique connection assignments.

Do not open the light section sensor yourself under any circumstances! There is otherwise a risk of uncontrolled emission of laser radiation from the light section sensor. The housing of the LRS contains no parts that need to be adjusted or maintained by the user. Before connecting the device please ensure that the supply voltage matches the value print- ed on the nameplate. Connection of the device and cleaning must only be carried out by a qualified electrician. If faults cannot be cleared, the LRS should be switched off from operation and protected against accidental use. The LRS light section sensors are designed in accordance with safety class III for supply by PELV (protective extra-low voltage with reliable disconnection). Notice! Protection class IP 67 is achieved only if the connectors and caps are screwed into place! The connectors used must be equipped with O-ring seals.

Leuze electronic 6.2 Shielding and line lengths The light section sensors of the 36/36HI series are equipped with modern electronics developed for industrial applications. In industrial environments, a number of sources of interference may affect the sensors. In the following, information is provided on EMC.compliant wiring of the sensors and of the other components in the switch cabinet and on the machine. Observe the following maximum line lengths: Shielding: 1. Ground the LRS housing: Connect the housing of the LRS via the functional earth (FE) screw provided for this purpose (see figure 6.3, devices produced after April 2011) with the protective conductor on the machine star point. The cable should have an impedance as low as possible for high-frequency signals, i.e., be as short as possible and have a large cross-sectional area (grounding strip, …). If the LRS does not yet have an FE screw of its own, please use one of the M4 holes on the dovetail. Important: Place a lock washer underneath and check the penetration of the anodized coating of the LRS housing by measuring the electrical connection from FE star point to the connector sleeves without connected sensor cables so that other FE interrup- tions can be detected on the machine base and profile rails as well. 2. Shield all connection cables to the LRS: Apply the shield to FE on both sides. On the LRS end, this is ensured if the LRS housing is connected to FE (PE) as described under 1. (shield fitted over the connector sleeves to the housing). In the switch cabinet, clamp the shield flat to FE. To do this, use special shielding clamps (e.g., Wago, Weidmüller, …). Keep the length of the shieldless end of the cable as short as possible. The shield should not be connected at a terminal in a twisted fashion (no "RF braid"). 3. Disconnect power and control cables: Lay the cables for the power components (motor cables, lifting magnets, frequency inverters, …) as far from the sensor cables as possible (distance > 30cm). Avoid laying power and sensor cables parallel to one another. Cable crossings should be laid as perpendicular as possible. 4. Lay cables close to grounded metal surfaces: This measure reduces interference coupling in the cables. Connection to the sensor Interface Max. line length Shielding Power supply unit X1 50m required Activation / cascading / trigger X1 50m required PC/Host X2 50m required Encoder X3 50m required Switching inputs / outputs X3 10m required PROFIBUS DP X4 10m required Table 6.2: Line lengths and shielding

37 TNT 35/7-24V 5. Avoid leakage currents in the cable shield: Leakage currents arise from incorrectly implemented equipotential bonding. There- fore, carefully ground all parts of the machine. Notice: You can measure leakage currents with a clip-on ammeter. 6. Star-shaped cable connections: To avoid interference between various consumers, ensure that the devices are con- nected in a star shape. This will prevent cable loops. General shielding information: Avoid spurious emissions when using power components (frequency inverters, …). The technical descriptions of the power components provide the necessary specifications according to which the respective power component satisfies its CE conformity. In practical work, the following measures have proven effective: • Screw the mains filter, frequency inverter flat on the galvanized mounting plate. • Mounting plate in the switch cabinet made of galvanized sheet steel, thickness 3mm • Keep cable between mains filter and inverter as short as possible and twist cables. • Shield both ends of the motor cable. • Ground the entire system well. Carefully ground all parts of the machine and of the switch cabinet using copper strips, ground rails or grounding cables with large cross section. Below, the EMC-compliant connection of the light section sensors LRS is described in prac- tical use with images.

Leuze electronic 6.3.3 Connection X3 - switching inputs/outputs (only LRS 36/6) Switching outputs of connection X3 Out1 to Out4 are each a logic combination of analysis results of the individual AWs. This logic operation is defined in LRSsoft (see chapter 9.4 "Parameter settings/Parameters tab"). Up to 16 different logic combinations of the AW's and respective result mappings on Out1 to Out4 can be combined into inspection tasks. Switching inputs of connection X3 The 3 switching inputs InSel1-3 are used to select the inspection task 0-7.

Leuze electronic Technical description LRS 45 TNT 35/7-24V 7.1.3 Displays The display changes depending on the current operating mode. There are the following three display modes: • Alignment aid and status display • Command mode • Menu display The menu display is accessed by pressing one of the two control buttons. Operation of the LRS via the menu is described in chapter 7.2.2. With PROFIBUS devices, the bus state is first displayed after power-on (displayed for approx. 3s). If the PROFIBUS was detected, alignment aid and status are then displayed. Alignment aid As an alignment aid, the current measurement value at the left edge (Lxxx), in the middle (Mxxx) and at the right edge (Rxxx) of the detection range is displayed in the OLED display in units of millimeters. If no object is detected or if the distance is too small, distance value 000 (mm) appears in the display. Align the light section sensor by rotating it about the y-axis in such a way that the same value is indicated for L, M, R. Status display In the second line of the display, the selected inspection task (Txx), the state of the four switching outputs (Qxxxx) or, for PROFIBUS devices, Out1 … Out4 of the input data byte uSensorInfo as well as the current sensor status (see chapter 4.2 "Operating the sensor") are displayed. The indication of the sensor state in the display has the following meaning: • fRun = Free Running • Trig = Triggering • !ACt = Activation (laser on/off) T12 means that Inspection Task 12 is currently active, for example. Value range: T00 to T15. Q0100 means Out1=0, Out2=1, Out3=0, and Out4=0, for example. Value range: Q0000 to Q1111. If, for PROFIBUS devices, no PROFIBUS is detected following power- on, no PB appears in the middle of the bottom line instead of Q0000. The following options are available for the sensor status: fRun means Free Running, Trig means triggered (see chapter 4.2.3 "Triggering - Free Running") and !ACK means that the sensor is deactivated (no laser line, see chapter 4.2.2 "Activation - laser on/off"). Command mode If the LRS is connected to a control, the control can put the LRS into a command mode in which it receives and executes commands (see chapter 10.2.9 "Evaluation telegram"). In command mode, the OLED display has one line. Command Mode appears on the first line of the display. waiting for PB L450 M450 R450 T00 fRun T00 Q0000 fRun T00 no PB fRun Command Mode

The currently active menu item is displayed with black text on a light-blue background. The  and  buttons both have different func- tions depending on the operating situation. These functions are represented via icons on the right edge of the display – i.e. to the immediate left of the buttons. The following displays may appear: Menu navigation  selects the next menu item (Ethernet).  switches to the submenu shown with inverted colors (Data Output).  selects the next menu item (IP Address).  returns to the next higher menu (). At the top menu level, the menu can be exited here (Menu Exit). The number of bars at the left edge indicates the current menu level: Selecting values or selection parameters for editing  selects the next menu item ( -> Net Mask Addr.).  selects edit mode for IP Address.

Notice To ensure that values that were changed via the menu are also applied, you should discon- nect the sensor from its power supply for a brief period after a change of values. 7.3 Reset to factory settings The factory settings can be reset in three different ways: • Hold down the  button while connecting the supply voltage • Factory Setting menu item • By means of the LRSsoft configuration software As an example, the first of the methods mentioned above is described below: When applying the supply voltage, press the  button to reset the configuration of the LRS to factory settings. The display shown next to here appears. Interrupting a reset Pressing  causes the adjacent display to appear. If you now press the  button, you will exit the menu without resetting the LRS to factory settings. Executing a reset Pressing the  button while the checkmark () is displayed causes the adjacent safety prompt to appear. Pressing  interrupts the reset process; reset canceled appears in the display for approx. 2s. Afterward, the LRS returns to detection mode. Pressing  resets all parameters to the factory settings. All settings made previously are permanently lost. reset done appears in the display for approx. 2s; the LRS then returns to normal operation. You can select the resetting to factory settings also via LRSsoft. In the Configuration menu select the entry Reset to Factory Settings.

52 Technical description LRS Leuze electronic 8 Commissioning and configuration 8.1 Switching on After switching on the supply voltage +UB and following error-free initialization of the device, the green LED illuminates continuously: the LRS is in detection mode. Notice After a warmup time of 30 min., the light section sensor has reached the operating temper- ature required for an optimum measurement. 8.2 Establish connection to PC The LRS is configured via a PC using the LRSsoft program before it is integrated into the process control. In order to be able to establish an UDP communication with the PC, the IP address of your PC and the IP address of the LRS must lie in the same address range. The LRS has no built- in DHCP client, so that you need to set the address manually. This is done the easiest way via the PC. Notice! If you use a desktop firewall, please make certain that the PC can communicate with the LRS via the Ethernet interface by means of UDP on ports 9008 and 5634 (these ports are preset at the factory, but may have been changed by the user, see chapter 7.2 "Menu description"). Furthermore, the firewall must allow ICMP echo messages to pass through for the connection test (ping). If the PC is usually connected to a network using DHCP address allocation, the easiest way to access the LRS is by applying an alternative configuration in the TCP/IP settings of the PC and connecting the LRS to the PC. Check the network address of the LRS by pressing the  button during detection mode of the LRS twice in succession, then by pressing  twice and followed by pressing the  button again. This will take you to the Ethernet submenu and enable you to read the current settings of the LRS consecutively when pressing  repeatedly. Make a note of the values for IP-Address and Net Mask Addr.. The value in Net Mask Addr. specifies which digits of the IP address of the PC and LRS must match so that they can communicate with each other. Address of the LRS Net mask Address of the PC 192.168.060.003 255.255.255.0 192.168.060.xxx 192.168.060.003 255.255.0.0 192.168.xxx.xxx Table 8.1: Address allocation in the Ethernet

Leuze electronic Technical description LRS 53 TNT 35/7-24V Instead of xxx you can now allocate any numbers between 000 and 255 to your PC, but NOT THE SAME numbers as contained in the address of the LRS. For example 192.168.060.110 (but not 192.168.060.003!). If LRS and PC have the same IP address, they cannot communicate with each other. Setting an alternative IP address on the PC Log into your PC as administrator. Using Start->System control go to the Network connections (Windows XP) menu or to the Network center and release center (Windows Vista) menu. There, select LAN Connection and right-click to open the corresponding properties page. Select the Internet protocol (TCP/IP) (by scrolling down, if necessary) and click on Properties. In the Internet protocol (TCP/IP) Properties window select the Alternate configuration tab. Set the IP address of the PC in the address range of the LRS. Attention: do not use the same as for the LRS! Set the subnet mask of the PC to the same value as on the LRS. Close the configuration dialog by confirming all windows using OK. Connect the interface X2 of the LRS directly to the LAN port of your PC. Use a KB ET-…-SA-RJ45 cable for the connection, see table 15.7 The PC first tries to establish a network connection via the automatic configuration. This takes a few seconds, after which the alternate configuration, which you just set, is activated. The PC can now communicate with the LRS. Information about configuring with the LRSsoft can be found in chapter 9.

54 Technical description LRS Leuze electronic 8.3 Commissioning For the commissioning and integration of the sensor in the process control the following steps are necessary: 1. LRS configuration - see chapter 9. 2. Programming process control - see chapter 10 and chapter 11. or 3. Connect switching inputs and outputs accordingly - see chapter 6.3. 4. When connecting in the Ethernet process controls, the IP configuration of the LRS is to be adjusted so that the LRS can communicate with the process control. The values corresponding to the following screenshot are preset in the LRS at the fac- tory. If you would like to set different values, you must change the values via the display of the LRS in menu item Ethernet (see "Menu description" on page 47). You can test the changed values by entering them in the Configuration area in LRSsoft and then clicking the Check Connectivity button. 5. Connect LRS to the process control. This can be performed for all LRS via the Ethernet interface or, depending on model, via the switching outputs or the PROFIBUS. 6. Establish connections for activation, triggering and cascading, if necessary. Notice on connecting multiple light section sensors via Ethernet If several sensors are to be activated, all sensors as well as the control must receive different IP addresses on the same subnet. For all sensors different ports must be configured in the Sensor area as well as in the Client/PC area.

Once the LRSsoft has established a connection to the LRS, the laser beam flashes. PROFIBUS settings (only LRS 36/PB) For PROFIBUS devices, you can set the slave address and the baud rate in the PROFIBUS tab. Figure 9.2: PROFIBUS settings Automatic detection of the baud rate / automatic address assignment The LRS 36/PB supports automatic detection of the baud rate and automatic address assignment via the PROFIBUS. The address of the PROFIBUS participant can be set automatically by the commissioning tool of the PROFIBUS system (a class 2 PROFIBUS master). For this purpose, the slave

64 Technical description LRS Leuze electronic address must be set to value 126 in the sensor (factory setting). This is performed by means of LRSsoft or via the display. The commissioning master checks whether a slave has address 126 and then assigns this slave a slave address smaller than 126. This address is permanently stored in the participant. The changed address can then be queried (and, if necessary, changed again) via the display or LRSsoft. The following baud rates can be set: Notice! After changing the PROFIBUS slave address via the display or LRSsoft, a power-on reset must be performed in order to permanently accept the address. For the changed settings to take effect, they must be transferred to the sensor! • Automatic • 9.6kBaud • 19.2kBaud • 45.45kBaud • 93.75kBaud • 187.5kBaud • 500kBaud • 1.5MBaud • 3MBaud • 6MBaud

Then go to the Analysis Functions panel and define analysis windows and their logic combination for your inspection task. Finally, save these settings as an Inspection Task by clicking on Apply Settings or Transmit to Sensor. 9.4.1 Task Parameters panel Inspection Task Selection In the Inspection Task Selection panel, you can select inspection tasks. Notice! By default, changeover of the inspection tasks via the PROFIBUS master (PLC) has priority over LRSsoft. In this field, the selection of the inspection task with LRSsoft is only possible if, under Global Parameters there is no tick in front of Enable External Inspection Task Selection. Otherwise, the inspection task can only be selected via the process interface. By removing the tick in the Enable External Inspection Task Selection check box, the inspection task cannot be changed via the process interface while configuration is being performed. After configuring with LRSsoft and before transmitting the settings to the sensor ('Transmit to Sensor'), the Enable External Inspection Task Selection check box must again be selected. Only then can inspection tasks be selected via the process interface.

66 Technical description LRS Leuze electronic The upper drop-down menu Inspection Task Selection lets you select one of the 16 possible inspection tasks. After the selection of the inspection task, the associated param- eters are loaded and displayed. You can edit these parameters and save the edited param- eters under the same name. In the Name field, you can assign a meaningful name (max. 12 characters) to the inspection task selected above and save it by clicking on Accept. By saving via the button Apply Settings, the currently displayed inspection task is temporarily stored in the sensor. When switched off, the data/settings are lost. By saving via Configuration -> Transmit to Sensor menu command all inspection tasks created are transmitted to the sensor, where they are permanently stored. Notice! If an inspection task was changed, permanent storage in the sensor should be performed with Configuration -> Transmit to Sensor. The common procedure for creating and storing inspection tasks is described in chapter 9.7, "Definition of inspection tasks" on page 76 . Operation Mode In Operation Mode you can configure using Free Running that the LRS continuously detects and outputs measurement data (factory setting). With Input Triggered the LRS captures measurement data only if a rising edge is present at the trigger input or if one of the "Ethernet Trigger" (chapter 10.3.4) or PROFIBUS Trigger (chapter 11.5) commands is being used. Detailed information on this topic can be found in chapter 4.2.3. Activation Under Activation the Regard setting has the effect that the laser is switched on and off according to the level at the activation input or via PROFIBUS. Detailed information on this topic can be found in chapter 4.2.2. When the Disregard setting has been selected, the laser always remains switched on, independent from the level at the activation input or the PROFIBUS activation (factory setting). Trigger Output Mode Under Trigger Output Mode you can activate the cascading output using Cascading. Detailed information on this topic can be found in chapter 4.2.4. When the Disable setting has been selected, the cascading output will not be set (factory setting). Light Exposure Using Light Exposure you can control the exposure duration of the laser during measure- ment value detection and adapt it to the reflective properties of the objects to be detected. Select an exposure setting that displays a continuous line around the object contour. Then try to achieve a line on a flat surface that is as continuous as possible.

The current settings regarding detection range and analysis windows must first be transmit- ted to the sensor via Apply Settings. The column Current Hits then shows values. In the Hits On column, you specify the number of hit points that must be detected for the evaluation result of the relevant AW to be "1", or for a green LED to be displayed in the column Current Status. The LED remains green until the number of detected hit points is equal to or smaller than the value you set in the Hits Off column. The entries in Hits On and Hits off thus let you configure a switching hysteresis to prevent an (unwanted) change of the switching state under admissible changes in the object position or other physical quantities. In figure 9.5, a total of three analysis areas have been defined. The task is to detect objects of the same width but different heights, and the position of the objects in the detection range: • AW01 detects that at least 2 objects of the specified width are present • AW02 detects that at least 1 tall object is present • AW03 detects that one tall object is present to the right • AW04 detects that one low object is present to the left By using a logic combination of the analysis results of these 4 AWs, you can configure the switching behavior of outputs Out1 to Out4 and the PROFIBUS process data in the Analysis Window Combination Tables panel.

70 Technical description LRS Leuze electronic Edit Logical Combinations Click on the Edit Logical Combinations button and the following window appears: Figure 9.6: "Analysis Window Combination Tables" window Parameter in the Analysis Window Combination Tables window: In the window of figure 9.7, you specify logic combinations of the evaluation results of indi- vidual AWs: For each output (Out1 to Out4), you first determine in the first &-column which AWs you want to combine via AND. The result of this combination is displayed the line OR above the respective column as 1 or 0. Where applicable, define further AND combinations in the remaining &-columns. You may thus define up to four different AND combinations of individual outputs in the 4 columns per output. The results of these four columns are automatically combined via OR. The output thus toggles when one of the four AND combinations results in a 1.

Depth Analysis depth1), i.e. number of the successive evaluations with identical result that are required for the switching output to toggle 1) Notice on analysis depth: By selecting a large value for the analysis depth, the LRS has a reliable switching behavior; the response time of the sensor increases correspondingly (example: analysis depth = 3 -> response time 3 x 10ms = 30ms). Interfering signals of individual scans are suppressed. If an analysis depth of "1" (factory stetting beginning with firmware version 01.25) is selected, the response time is 10 ms. 1 … 255 Negation Negation of the result of the OR line On/Off OR line Results of the &-columns.

Leuze electronic Technical description LRS 71 TNT 35/7-24V Example: Figure 9.7: Definition of logic combinations of several AWs In the example above, the AW definitions of figure 9.5 apply. This means that, with the setting for the switching outputs shown: • OUT1 is active (=1) - if an object is present in AW01 (AW01+) AND if no object is present in AW02 (AW02-) OR - if an object is present in AW03 (AW03+). • OUT2 is not active (=0, because the Negation tick is set) - if no object is present in AW01 (AW01-) AND if an object is present in AW02 (AW02+) OR - if an object is present in AW04 (AW04+). • OUT3 is active (=1) - if an object is present in AW03 (AW03+) AND if an object is present in AW04 (AW04+). • OUT4 is active (=1) - if an object is present in AW03 (AW03+) AND if no object is present in AW04 (AW04-). As figure 9.7 shows, logic combinations can thus be used to define various detection tasks. The good/bad result of the logic column links is shown in color in line OR. In the example shown here, column 2 is green for OUT1 because an object is present in AW03. Because the columns of OUT1 are linked with OR, OUT1 is active and displayed in green. The analysis depth Ana. Depth is set to 10. This means that 10 identical evaluations must occur in sequence in order to cause the switching output to toggle.

72 Technical description LRS Leuze electronic 9.4.3 Single Shot Mode area In Single Shot Mode, the sensor carries out an individual analysis only when you click on the Request Measurement button and displays the result in LRSsoft until Request Measurement is clicked again. 9.4.4 Global Parameters area Under Global Parameters, you can use Enable External Task Selection to configure whether or not the inspection tasks 0-7 can be selected via the inputs InSel1-InSel3 or PROFIBUS. Inspection tasks 0-15 can be selected via PROFIBUS. Notice! If Enable External Inspection Task Selection is ticked, the inspection task can only be selected via the inputs or PROFIBUS. In this case, the drop-down menu under Inspection Task Selection has no function.

Leuze electronic Technical description LRS 73 TNT 35/7-24V 9.5 Detection function/Visualization tab Click the Visualization tab to display the chronological trend of the states of AWs and switching outputs or of the states of the uSensorInfo sensor outputs (byte 2) for the PROFIBUS device: Figure 9.8: LRSsoft Visualization 9.5.1 Evaluating saved detection data To evaluate a detection data set, you can record, store and reopen detection data as described in chapter 9.6.3. A stored detection data set can be opened with LRSsoft via the Recording -> Archive -> Open Record menu. Notice! After opening a detection data set, the current parameter setting of the LRS should be trans- mitted (see chapter 9.6.2) so that the current sensor configuration is displayed on Hits On and Hits Off. In default mode, the detection data in the Visualization tab run through continuously. To stop this continuous display and to be able to examine individual data sets you must click on the arrow on the toolbar. The sliders in the Replay Control area serve to evaluate them. Spooling permits the fast shifting of the displayed section of 100 individual results across all data of the detection data set (which can easily contain several hundred individual results). Here, the value in First Status shows the number of the measurement that is displayed at 0 and the value in Last Status the number of the measurement displayed at 100.

74 Technical description LRS Leuze electronic Use the Status Selection slider to specify which of the individual data sets displayed in the right window area is shown in the individual results of the AWs and switching outputs or the states of the uSensorInfo sensor outputs (byte 2) for the PROFIBUS device. The asso- ciated data set number is displayed under Profile No. The Show Plane option marks this individual data set with a solid black line. 9.6 Menu commands 9.6.1 Saving parameter settings/File menu The File menu is used to save parameter data to the PC. In this way, settings for various detection tasks can be defined within the scope of commis- sioning and stored on data carriers and parameter files. During operation, the LRS is reconfigured via Inspection Tasks. A parameter file stored on a data carrier can only be used with LRSsoft config- uration software! • New creates a new configuration file. • Open opens a configuration file from the data carrier. • Save saves the open configuration file with the same name. • Save as saves the open configuration file under a different name. • Save as default saves the open configuration as the default setting which is always loaded when LRSsoft is opened. In addition, the File menu offers the possibility to export the following views format to data carriers (available formats: *.png, *.jpg, *.bmp, *.tif): • Profile View: the current view as 2D view • AW States View: chronological trend of the state of all 16 AW's • Output States View: chronological trend of the states of the 4 switching outputs or of the states of the uSensorInfo sensor outputs (byte 2) for the PROFIBUS device 9.6.2 Transmitting parameter settings/Configuration menu The Configuration menu is used to exchange parameter data with the connected LRS. • Load from Sensor loads all parameter settings for all defined inspection tasks from the LRS and displays them in the software. • Transmit to Sensor permanently stores all parameter settings of all defined inspection tasks from the configuration software in the LRS. • Reset to factory settings resets the LRS to factory settings.

Leuze electronic Technical description LRS 75 TNT 35/7-24V 9.6.3 Managing detection data/Measure Records menu Detection data are defined here as the results of individual analysis windows and the states of the switching outputs. The Recording menu is used for managing detection data in *.csv format on the PC. • New... creates a new detection data set. Following a file name query dialog, another dialog appears. It requires you to enter how many single scans (2D profiles) are to be saved in the file. • Archive -> Open Record opens a saved detection data set. • Archive -> Close record closes the opened detection data set. 9.6.4 Zoom and Pan/toolbar The Zoom in / Zoom out and Pan buttons of the toolbar allow individual areas of the view to be enlarged for better visual evaluation: Figure 9.9: Zoom function After activating the magnifying glass, each click on the view enlarges the displayed section. The enlarged section can then be shifted with the activated hand function to display the area of interest. Notice! The click-and-drag method for zooming known from other programs is not possible here. Before LPSsoft is operated further, the tool buttons (Zoom, Pan, …) must be activated. Zoom In Enlarge area: 1.

76 Technical description LRS Leuze electronic 9.7 Definition of inspection tasks Typical procedure 1. Start LRSsoft and connect the sensor: Click on the Connect to sensor button: . 2. Fetch the configuration from the sensor via Load from Sensor or load it from the data carrier with Open. 3. Remove the tick at Enable Selection Inputs. 4. Use Inspection Task Selection to select the inspection task to be modified. 5. Display and, if necessary, enlarge 2D view of the detection range in the Parameters tab. 6. Define required (E)AWs with mouse or keyboard in the Analysis Windows Defi- nitions window (Edit Analysis Windows button); confirm each of the set (E)AWs with Apply Settings. - Within an AW, the pixels of the current 2D profile are determined by the LRS (Current Hits). - For each AW, the user then configures an upper and a lower limit for the hits (Hits On/Off) and thus a switching hysteresis. - The result is an ok or not ok status, signaled via a green or red status display. Notice! The number of Current Hits does not necessarily correspond with the object size, since the number of hits is dependent on distance z. At near distance to the sensor (e.g., 300 mm) an object expanded in the X direction has nearly twice as many hits as it does at a far distance (e.g, 600mm). If the object distance is the same, the number of hits remains nearly constant. 7. Generate switching information for the outputs Out1 to Out 4 or PROFIBUS process data in the Analysis Window Combination Tables window (button Edit Logical Combinations): - Columnar AND combination of the results (inverted, if applicable) of individual AWs - OR combination in line OR of up to four AND results - If applicable, inversion of the result of the OR combination (tick in Negation) - Input for the evaluation depth 8. Assign a name (Name) to the inspection task and confirm with Accept. 9. Temporarily transfer the inspection task with Apply Settings. 10. Where applicable: define further inspection tasks with steps 5.-9. 11. Tick Enable Selection Inputs again. 12. Permanently transfer the configuration including all inspection tasks to the sensor with Transmit to Sensor. 13. Where applicable: save the configuration to data carrier with Save As… 14. Finally, disconnect the connection to the sensor: click on the button Disconnect from sensor: .

Leuze electronic Technical description LRS 77 TNT 35/7-24V 10 Integrating the LRS in the process control (Ethernet) 10.1 General information The LRS communicates with the process control via UDP/IP using the protocol described in chapter 10.2. The protocol operates in two different modes: • Detection mode • Command Mode In detection mode, the LRS transmits the evaluation telegram. This is continuously trans- mitted in "Free Running" operation; in triggered operation, it is transmitted only once per trigger. In command mode the LRS reacts to commands from the control. The commands available are described in chapter 10.3. Notice! If you use a firewall, please make certain that the control can communicate with the LRS via the Ethernet interface by means of UDP on ports 9008 and 5634 (these ports are preset at the factory, but may have been changed by the user, see chapter 7.2 "Menu description"). Furthermore, the firewall must allow ICMP echo messages to pass through for the connec- tion test (ping). The integration of PROFIBUS device model LRS 36/PB in the process control via PROFIBUS is described in chapter 11 "Integration of the LRS 36/PB in the PROFIBUS" on page 92. 10.2 Protocol structure: Ethernet Notice! The sequence in which the individual bytes are saved varies depending on the operating system. The commands in chapter 10.3 and the protocol description are represented in "big endian" format, i.e., the high-byte first followed by the low-byte (0x… hexadecimal). Windows PCs (and many controls, such as the Siemens S7), however, store data in the "little endian" format, i.e. the low byte first followed by the high byte. If, in your process environment, the LRS does not respond to commands from the control even though communication with LRSsoft functions properly, check whether the problem lies with the byte order. Example: for command 0x434E (Connect to Sensor) a Windows PC must transmit 0x4E and 0x43 in order for it to be understood by the LRS. In the transaction number of the answer from LRS there is then also 0x4E43 (byte sequence 0x43, 0x4E). The LRS sends data as "little endian", i.e., first the low byte and then the high byte. The possible values of individual bytes and their meaning are described below.

78 Technical description LRS Leuze electronic Protocol structure The protocol consists of the header (30 bytes) followed by the user data (0 … 53 data words @ 2 bytes). The protocol is used both in command mode when transmitting commands and when acknowledging sensor commands as well as in detection mode. Header 10.2.1 Command number The command number specifies both the command from the control to the sensor as well as the command from the sensor to the control (see chapter 10.3). In detection mode, the sensor always sends an evaluation telegram with command number 0x5354. 10.2.2 Packet number The packet number serves internal maintenance purposes of the manufacturer. 10.2.3 Transaction number In detection mode 0x0000 is displayed here In command mode, the command acknowledgment of the sensor contains the command number of the command that is answered.

With the LRS, this value is always 0x0000 0000. Length 2 bytes, fixed value: 0x0000 Length 2 bytes, value range: 0x0000 … 0xFFFF Length 2 bytes, fixed value: 0x0010 Length 2 bytes, possible values: 0x0000 / 0x0001 / 0x0002 / 0x0003 / 0x0178 Length of the header: 30 bytes

Leuze electronic Technical description LRS 79 TNT 35/7-24V 10.2.4 Status Indicates the state of the sensor. The state is coded as follows: The LSB of the high byte is always set to 1 as long as the parameter Activation Input has been set to Disregard (Always on) in LRSsoft. If parameter Activation Input is set to Regard, the state of the bit corresponds to the state of the signal of an activation source (input, Ethernet activation). Notice! Independent of the mode that is currently active, the sensor switches to menu mode if a button if the display is touched and then neither responds to commands nor does it transmit measurement data. Menu mode automatically ends after 3 minutes if no buttons are pressed. Alternatively, the user can end menu mode with the Exit menu item. 10.2.5 Encoder High / Low The encoder counter is implemented in sensor models with encoder input. All other sensors permanently display 0x00000000. The 4 bytes in Encoder High and Encoder Low specify the encoder counter value for light section sensors with encoder interface. The maximum value is 0xFFFF FFFF.

After each measured profile, this number increases by 1. The maximum value is 0xFFFF. Beyond that an overflow to 0x0000 occurs. The Z- and X-data belonging to a measurement are identified via the same scan number. 10.2.7 Type Specifies how the detection data are to be interpreted. The fixed default value is 0x0010. 10.2.8 Number of user data The user data have a variable length of 0, 1, 2, 3 or 53 data words (0, 2, 4, 6 or 106 bytes).

Leuze electronic Technical description LRS 91 TNT 35/7-24V 10.5 Operation with LxS_Lib.dll The LxS_Lib.dll is a .NET 2.0-compatible collection of functions which considerably facili- tates the integration of all Leuze light section sensors (LPS, LRS and LES) into PC environ- ments. The LxS_Lib.dll can be used in a variety of programming languages, such as C#, Visual Basic, etc. The integration into MatLab is also possible. The DLL can control several light section sensors via Ethernet. The LxS_Lib.dll supports the following functions, among others: • Establishment/deactivation of sensor connection • Evaluation of sensor state • Triggering, activation via Ethernet • Activation of individual inspection tasks • Loading and saving all created inspection tasks • Activation of inspection tasks • Parameter changes of the active inspection task In addition, the LxS_Lib.dll enables the evaluation of specific user data of the LPS, LES or LRS. With the LRS and LES, all sensor information and intermediate results are available so that much more complicated evaluations can be realized in the process control. Access The library is contained on the supplied product CD. Alternatively, you can download the program in the Internet at www.leuze.com. 10.6 Additional support when integrating sensors Additional tools (e.g. MatLab example, function modules S7, protocol plain-text decoding, UDP terminal) are available. Please contact your Leuze distributor or service organization to acquire these.

92 Technical description LRS Leuze electronic 11 Integration of the LRS 36/PB in the PROFIBUS 11.1 General information The LRS 36/PB is designed as a PROFIBUS DP/DPV1 compatible slave. The input/output functionality of the sensor is defined by the corresponding GSD file. The baud rate of the data to be transmitted is max. 6MBit/s under production conditions. For operation, the GSD file is to be appropriately modified. The LRS 36/PB supports automatic detection of the baud rate Characteristics of LRS 36/PB • Ethernet and PROFIBUS can be used simultaneously in detection mode as fully-fledged interfaces. • If the sensor is in menu mode, the PROFIBUS is active. Queries from the control are not processed and the process data are frozen (indicated by the constant scan number). • If the sensor is in command mode, the PROFIBUS is active. Queries from the control are not processed and the process data are frozen (indicated by the constant scan number). • If the sensor is simultaneously operated with LRSsoft and PROFIBUS, the PROFIBUS is active. Queries from the control are processed with a delay; the process data are also updated with a delay (indicated by the slowly increasing scan numbers). The update occurs every 200ms. • The input signals via Ethernet, PROFIBUS and signal lines have equal priority. The first incoming signal is executed. • The sensor is configured via the LRSsoft configuration software. Compared to device model LRS 36/6 with switching outputs, the PROFIBUS model has the following additional functions: • Output of the status of 16 analysis windows • Output of hits (current hits) in up to 16 analysis windows • Result of logic combinations • Transmission of scan number and sensor status • Selection of up to 16 inspection tasks • Activation and trigger via PROFIBUS The restriction on the selection of maximum 8 inspection tasks via the switching inputs for the LRS 36/6 does not exist for the LRS 36/PB. Up to 16 different inspection tasks can be activated by the control

Leuze electronic Technical description LRS 93 TNT 35/7-24V 11.2 PROFIBUS address assignment The various possibilities for setting the slave address are described in the following. Automatic address assignment via the PROFIBUS (slave address 126) is preset. Automatic address assignment The LRS 36/PB supports automatic detection of the baud rate and automatic address assignment via the PROFIBUS. The address of the PROFIBUS participant can be set automatically by the commissioning tool of the PROFIBUS system (a class 2 PROFIBUS master). For this purpose, the slave address must be set to value 126 in the sensor (factory setting). The commissioning master checks whether a slave has address 126 and then assigns this slave a node address smaller than 126. This address is permanently stored in the participant. The changed address can then be queried (and, if necessary, changed again) via the display or LRSsoft. Address assignment with LRSsoft The PROFIBUS slave address can be set via LRSsoft. This setting can be stored on the PC together with the other sensor settings. Figure 11.1: PROFIBUS address assignment with LRSsoft Address assignment with key pad and display Setting the address with the key pad and display allows the sensor to be integrated in a PROFIBUS system while in the field with no additional tools. See "Slave Address" on page 48. The set address can also be queried by the user with no additional tools. Notice! After changing the PROFIBUS slave address via LRSsoft or with the display/key pad, a power-on reset must be performed in order to permanently accept the address.

94 Technical description LRS Leuze electronic 11.3 General information about the GSD file If the LRS is operated in a PROFIBUS network, configuration can be performed exclusively via the LRSsoft configuration software. The functionality of the inputs/outputs of the light section sensor to the control is defined via modules. Using a user-specific configuration tool, the respective required modules are integrated and configured according to the measure- ment application during PLC programming. During operation of the light section sensor on the PROFIBUS, the functionality of the inputs/ outputs is assigned default values. If these values are not changed by the user, the device operates with the default settings set by Leuze electronic on delivery. Please refer to the following module descriptions for the default settings of the device. Notice! At least one module from the GSD file must be activated in the configuration tool of the control, usually module M1 or M2. Notice! Some controls make available a so-called "universal module". This module must not be activated for the LRS 36/PB. Attention! The device makes available a PROFIBUS interface and an Ethernet interface. Both interfaces can be operated in parallel. Notice! For test purposes, parameters can be changed on a LRS 36/PB operated on PROFIBUS. At this time, object detection is not possible on PROFIBUS. Notice! All input and output modules described in this documentation are described from the perspective of the control: Described inputs (I) are inputs in the control. Described outputs (O) are outputs in the control. Described parameters (P) are parameters of the GSD file in the control. Notice! The current version of the GSD file LEUZE401.GSD for the LRS 36/PB can be found on the Leuze website at Download -> detect -> Measuring sensors.

Leuze electronic Technical description LRS 95 TNT 35/7-24V 11.4 Overview of the GSD files The LRS 36/PB has one module slot. Select the corresponding module from the GSD to set the process data of the LRS 36/PB that are to be transmitted . Several modules are available for selection. Beginning with the simplest input module M1, additional inputs are included with the subsequent modules. All available output data are already contained in module M1. The modules with higher numbers the modules with the lower numbers (example: M2 contains M1 and the extensions of M2). Notice! As the module number increases, so too does the number of user data bytes that are to be transmitted. The maximum detection rate of 100Hz can only be ensured up to module M3. Therefore, only modules which contain the data actually required should be selected, i.e. the smallest possible module number should be selected. Notice! All input and output modules described in this documentation are described from the perspective of the control: Described inputs (I) are inputs in the control. Described outputs (O) are outputs in the control. Described parameters (P) are parameters of the GSD file in the control.

Leuze electronic Technical description LRS 97 TNT 35/7-24V 11.5 Output data description PROFIBUS trigger So that a measurement can be triggered on each PROFIBUS cycle, the PROFIBUS trigger of the LRS responds to a change of master output byte uTrigger. The control only needs to increment the trigger value in order to initiate a new measurement. The maximum trigger frequency is 100Hz. If triggering occurs during a measurement, the trigger signal is ignored, as is the case in the Free Running operating mode (shown on display: fRun). Activation - Sensor activation Alternatively, activation can be switched on in detection mode via activation input InAct (pin 2 on X1) or master output uActivation = 1. Notice! With the Disregard parameter setting in LRSsoft, the sensor is always activated; input InAct and activation via PROFIBUS are ignored. Inspection Tasks - Selection of inspection tasks With master output uInspTask (bits IT_b3 … IT_b0 in output data byte 2), inspection tasks 0 … 15 can be selected. The changeover occurs in cyclical IO operation and lasts approx. 70ms. During the changeover, the PROFIBUS IO data are frozen and the internal reconfiguration occurs. This is indicated by the scan number, which does not increase. After changing the inspection task, the PROFIBUS IO data of the sensor are again updated. Value uSensorInfo in the input data then indicates the inspection task set in the sensor and the scan number again increases with each new measurement. Attention! While configuring the LRS with LRSsoft via Ethernet, global parameter Enable External Inspection Task Selection should be switched off so that the inspection task is not auto- matically changed by the control during configuration. After configuring, the check box for this parameter must be selected again before the con- figuration is transmitted to the sensor by means of Transmit Configuration To Sensor. Otherwise, inspection tasks can no longer be selected via PROFIBUS!

98 Technical description LRS Leuze electronic 11.6 Input data description Several modules are available for selection. Beginning with the simplest input module M1, additional inputs are included with the subsequent modules. All available output data are already contained in module M1. The modules with higher numbers the modules with the lower numbers (example: M2 contains M1 and the extensions of M2). 11.6.1 Module M1 Module M1 provides the minimum required PROFIBUS data The maximum detection rate of 100Hz is ensured if this module is set. Scan number The scan number is made available as PROFIBUS master input. This is a 16-bit value (bytes wScanNum, HighByte and LowByte). The scan number is increased by 1 on each measurement. In FreeRunning mode, the scan number also increases even if no sensor is explicitly activated. In triggered mode, the scan number is increased on each (successful) trigger. If the inspection task is changed, the PROFIBUS IO data of the sensor are frozen and the scan number does not change. Notice! It is recommended that the scan number be monitored in the application in order to deter- mine whether the data are actually new. Sensor info Byte uSensorInfo contains states of the internal (virtual) switching outputs of the sensor Out4 … Out1 in the high-nibble (bit 7 … 4) and the inspection task set in the sensor IT_b3 … IT_b0 in the low-nibble (bit 3 … 0).
