indicator may be configured as a fieldbus node or as a fieldbus listener. When used as a fieldbus node the indicator is configured via the fieldbus host although the instrument address may be entered via the front panel push buttons using the menu shown in Fig 4. For detailed node conditioning information please refer to the BEKA PROFIBUS PA Display – Fieldbus Interface Guide which may be downloaded from the BEKA website www.beka.co.uk As a fieldbus listener, the BA448CF-P is not visible to the fieldbus host and can only be configured via the front panel push buttons using the menu shown in Fig 6. Throughout this manual the BA448CF-P push buttons are identified P E ▼ ▲ and legends displayed by the instrument are shown within inverted commas e.g. ‘CodE’ and ‘Enb’. 6.1 Configuration menus The configuration menus are separated into two sections, fieldbus node and fieldbus listener. Both contain the ‘tYPE’ function that enables transfer between the two. Unless otherwise requested when ordered, all PROFIBUS PA BA448CF-P instruments are supplied as a fieldbus node with default configuration but can easily be reconfigured on-site. 6.2 Node configuration menu The node configuration menu is shown in Fig 4. Access to the menu is obtained by operating the P and E buttons simultaneously. If the BA448CF-P is not protected by an access code the first parameter 'Addr’ will be displayed. If the instrument is protected by an access code, ‘CodE’ will be displayed first. Pressing P will allow the four digit security code to be entered digit by digit using the ▼ or ▲ button to adjust the flashing digit and P to move control to the next digit. When the correct code has been entered, pressing E will cause the first parameter ‘Addr’ to be displayed. If an incorrect code is entered, or no button is pressed for ten seconds, the BA448CF-P will automatically return to the display mode. 6.2.1 Enter fieldbus address ‘Addr’ This function enables the fieldbus address of the BA448CF-P to be entered via the push buttons. Select ‘Addr’ in the node menu using the ▼ or ▲ button and press P to enter the function. This will reveal the existing three digit decimal address with the left hand digit flashing which may be changed by operating the ▼ or ▲ button. When set as required operating the P button will transfer control to the next digit that may be adjusted in the same way. When all digits are set as required operating the E button will enter the new address and the indicator will restart in the display mode after completing the initialisation sequence. If the address is not changed, operating the E button will return the display to the ‘Addr’ prompt in the node configuration menu. 6.2.2 Access code for configuration menu ‘CodE’ Access to the node configuration menu may be protected by a four digit security code which must be entered to gain access. New instruments are supplied configured with the default code 0000 which disables this protection and allows unrestricted access to the configuration menu. To enter a new access code select ‘CodE’ in the node configuration menu by operating the ▼ or ▲ button. To enter the function press P which will reveal the current access code with one digit flashing. The code may be changed using the ▼ or ▲ button to adjust the flashing digit and the P button to move control to the next digit. When the required code has been selected, press E to enter the selection and return to the ‘CodE’ prompt in the configuration menu. The revised access code will be activated when the transmitter is returned to the display mode. If the access code is lost please contact BEKA associates. 6.2.3 Change from node to listener ‘tYPE’ This function enables the instrument to be changed from a fieldbus node to a fieldbus listener. Select ‘tYPE’ in the node configuration menu using the ▼ or ▲ button.

When the four letters of ‘5urE’ have been entered operating the E button will reset the BA448CF-P to the factory defaults. Any existing configuration and addresses will be lost when the instrument is reset. FIG 4 Node configuration menu 6.3 Listener configuration menu When used as a fieldbus listener the BA448CF-P is not visible to the fieldbus host and can only be configured using the front panel push buttons shown in Fig 2. The listener configuration menu is separated into three sections, ‘SCAn’, ‘LISt’ and ‘Edit’, plus three housekeeping functions ‘CodE’, ‘tYPE’ and ‘rESEt’ as shown in Fig 6. ‘SCAn’ is the simplest method of configuration if the addresses of the data sources to be displayed by the BA448CF-P listener are not known. In the ‘SCAn’ function pressing the P button causes the BA448CF-P listener to search the fieldbus segment to which it is connected for all data sources. The hexadecimal device addresses for each data source are displayed as shown in Fig 5. The ▼ and ▲ push buttons scroll the display through all the data sources on the segment showing the source and destination address for each one. To aid identification, operating the P button will preview the value of the data at the selected addresses with a zero index i.e. the first five bytes in the data string. If the format of the data is not DS-33 (status + float) ‘no dAt’ will be displayed. The selected source and destination addresses may be allocated to one of the eight BA448CF-P listener inputs in-1, to in-8. Operating the P button will reveal the current listener input which may be changed using the ▼ or ▲ push button, when set as required, operating the E push button will enter the allocation. If the process variable to be displayed is located further along the data stream i.e. has an index greater than 5, the required index must be entered via the index ‘ind’ function in the edit sub-menu. A worked configuration example illustrating this procedure is contained in the Quick Set-up section of the BEKA PROFIBUS PA Display – Fieldbus Interface Guide. Fig 5 Device Addresses If the source and destination addresses and index of the process variable to be displayed by the BA448CF-P listener are known, they may be directly entered via the edit sub-menu. This sub- menu also provides full control of both the numeric and bargraph display parameters.

obtained by operating the P and E buttons simultaneously. If the BA448CF-P listener configuration menu is not protected by an access code the first parameter 'SCAn’ will be displayed. If the BA448CF-P is protected by an access code, ‘CodE’ will be displayed first. Pressing P will allow the four digit security code to be entered digit by digit using the ▼ or ▲ button to adjust the flashing digit and P to move control to the next digit. When the correct code has been entered, pressing E will cause the first parameter ‘SCAn’ to be displayed. If an incorrect code is entered, or no button is pressed for ten seconds, the indicator will automatically return to the display mode. Section 6.3.2 contains a summary of each configuration function including a cross reference to a more detailed description. 6.3.2 Summary of listener configuration functions Instrument Summary display of function ‘SCAn’ Scan fieldbus segment Identifies all data sources on the fieldbus segment to which the listener is connected and enables selected data to be allocated to one of the eight listener inputs in-1 to in-8.

This section contains a detailed description of each function in the listener configuration menu. It should be read in conjunction with Fig 6. 6.4.1 Scan fieldbus segment ‘SCAn’ If the Device Addresses of a data source are not known, the ‘SCAn’ function provides a simple way to identify them. This function scans the fieldbus segment to which the BA448CF-P listener is connected and identifies all the data sources. To aid identification the value of the process variable with a zero index i.e. the first five bytes in the data string at the address may be pre-viewed. The BA448CF-P listener only supports DS-33 formatted data (status+float) which is the usual format for analogue process variables. The ‘SCAn’ function will identify, irrespective of format, all data sources on the segment whose destination address is five bytes long. When pre-viewed, non DS-33 formatted data will produce a ‘no dAt’ error message. ‘SCAn’ is the first function displayed when entering the configuration menu, or it may be selected from within the menu by operating the ▼ or ▲ button. To scan the fieldbus segment to which the listener is connected for all data sources press P which will reveal the hexadecimal source address and destination address of the first data source found as shown in Fig 5. If there is more than one data source, operating the ▼ or ▲ button will scroll though all of them. If there are no data sources on the fieldbus segment the BA448CF-P listener will display ‘noSrC’. When the source and destination addresses of a data source are displayed, to aid identification the value of the process variable with a zero index i.e. the first five bytes in the data string may be pre- viewed by operating the P button. If this confirms that it is the required address, it may be allocated to one of the eight BA448CF-P listener inputs in-1 to in-8. To select the required listener input, press P which will display the first input in-1. Operating the ▼ or ▲ button will scroll the display through the other inputs. When the required input is displayed pressing E will allocate the selected data source address to the selected input and return the display to the source and destination addresses from which another data source address may be selected. When a data source address is allocated to a listener input any previous allocation will be overwritten. If the required process variable has an index above 5 i.e. it is not the first five bytes in the data string, the required index should be entered via the ‘ind’ function in the Edit sub-menu which is described in section 6.4.7 6.4.2 List configured input parameters ‘LiSt’ The ‘LiSt’ function enables the Source Address, Destination Address and Index allocated to each listener input to be viewed without danger of it being accidentally changed. The ‘LiSt’ function may be selected from within the menu by operating ▼ or ▲ button. To enter the function press P which will display the listener input currently selected in the display mode, other inputs may be selected using the ▼ or ▲ button. Operating the P button will cause the following parameters for the selected input to be displayed sequentially: Display Explanation ‘Enb:Y or N’ Input Enabled yes or no ‘SrC :00’ Source Address ‘dSt :00’ Destination Address ‘ind :00’ Index The display then automatically returns to the selected BA448CF-P listener input from where another input may be selected. If one of the eight BA448CF-P Listener’s inputs in- 1 to in-8 has not had a Source Address, Destination Address and Index allocated to it, ‘LiSt’ will show both addresses as ‘FF’ and the index ‘ind’ as ‘00’. 6.4.3 Enter address & display parameters ‘Edit’ The ‘Edit’ sub-menu may be selected from within the menu by operating ▼ or ▲ button. To enter the function press P which will display the listener input currently selected in the display mode, other listener inputs may be selected using the ▼ or ▲ button. When the required input has been selected operating the P button will enter the edit sub-menu at ‘Enb’ for the selected input. 6.4.4 Enable selected input ‘Enb’ ‘Enb’ turns the listener input selected in the Edit function on or off without affecting the conditioning. To enter the function press P which will reveal whether the selected input is ‘on’ or ‘oFF’. Operating the ▼ or ▲ buttons will toggle between the two conditions. When set as required operating the E button will enter the selection and return to the ‘Enb’ prompt in the edit sub-menu.

This function allows a known fieldbus device source address to be entered and allocated to the listener input selected in the edit function. To enter the function press P which will reveal the existing two digit hexadecimal address with one digit flashing which may be changed by operating the ▼ or ▲ button. When set as required operating the P button will transfer control to the second digit that may be adjusted in the same way. When both digits are set as required operating the E button will enter the selection and return to the ‘SrC’ prompt in the edit sub-menu. 6.4.6 Enter destination address ‘dSt’ This function allows a known fieldbus device destination address to be entered and allocated to the listener input selected in the Edit function. To enter the function press P which will reveal the existing two digit hexadecimal address with one digit flashing which may be changed by operating the ▼ or ▲ button. When set as required operating the P button will transfer control to the second digit that may be adjusted in the same way. When both digits are set as required operating the E button will enter the selection and return to the ‘dSt’ prompt in the edit sub-menu. 6.4.7 Enter Index ‘ind’ Index defines the location of the required process variable in the data string. The ‘ind’ function allows a known Index for the selected fieldbus Source Address to be entered and allocated to the BA448CF-P listener input selected in the Edit function. The data location is manufacturer specific and can not be automatically determined; the device documentation should therefore be consulted. To enter the function press P which will reveal the existing two digit hexadecimal Index with one digit flashing which may be changed by operating the ▼ or ▲ button. When set as required operating the P button will transfer control to the second digit that may be adjusted in the same way. When both digits are set as required operating the E button will enter the selection and return to the ‘ind’ prompt in the edit sub-menu. 6.4.8 Decimal point position ‘dP’ This defines the position the decimal point in the numeric display. To enter the function press P which will reveal the existing decimal point position. Operating the ▼ or ▲ button will move the decimal point to the required position, omit it, or activate all the decimal points which automatically provides maximum resolution in the display mode irrespective of the numeric value. When positioned as required, operating the E button will enter the selection and return to the ‘dP’ prompt in the edit sub-menu. 6.4.9 Configuration of bargraph display ‘bAr’ This function contains three sub-functions that enable the bargraph, justify its position and define the relationship between the bargraph and the instrument’s numeric display. Sub-function ‘b.tYPE’ enables the bargraph to be left, centre or right justified, or to be turned off. Sub-functions ‘bArLo’ and ‘bArhi’ define the listener’s numeric display at which the bargraph starts and is at full scale. The ‘bAr’ function may be selected from within the edit sub-menu by operating the ▼ or ▲ button. To enter the function press P which will display the ‘b.tYPE’ sub-function, pressing P again will reveal the existing bargraph justification. The ▼ or ▲ button will scroll through the four options, when the required justification is displayed, pressing E will enter the selection and return the display to the ‘b.tYPE’ prompt in the edit sub-menu from which ‘bArLo’ may be selected using the ▼ or ▲ button. ‘bArLo’ defines the listener’s numeric display at which the bargraph starts, to enter the function press P which will reveal the existing setting. The display may be changed using the ▼ or ▲ button to adjust the flashing digit and the P button to move control to the next digit. When the required starting display has been selected, press E to return to the ‘bArLo’ prompt in the edit sub-menu from which the ‘bArHi’ function may be selected. ‘bArHi’ defines the listener’s numeric display at which the bargraph is full scale, to enter the function press P which will reveal the existing setting. The display may be changed using the ▼ or ▲ button to adjust the flashing digit and the P button to move control to the next digit. When the required display has been selected, press E twice to enter the new values and return to the ‘bAr’ prompt in the edit sub-menu. Note: If the ‘dP’ function has been set to provide automatic maximum resolution irrespective of the displayed value, it may be necessary to manually position the decimal point before adjusting ‘bArLo’ or ‘bArHi’. This can be achieved by repeatedly operating the P button until the activated decimal point flashes, the decimal point can then be positioned using either the ▼ or ▲ button. Pressing the P button again will return control to one of the digits. 6.4.10 Scale numeric display ‘SCALE’ A scaling factor ‘Gain’ and an offset ‘oFFSt’ may be applied to the fieldbus process variable using this function, thus allowing the listener to display the fieldbus process variable in alternative units.

This flashing digit may be changed by operating the ▼ or ▲ button; when adjusted the P button will move control to the next digit or to the decimal point which can be positioned using the ▼ or ▲ button. When ‘GAin’ has been set to the required value operating the E button will enter the selection and return to the ‘GAin’ prompt in the sub-menu from where the ‘oFFSt’ function can be selected using the ▼ or ▲ button. To enter the ‘oFFSt’ function press P which will reveal the existing offset with one digit flashing. Again the flashing digit may be changed by operating the ▼ or ▲ button and the P button will move control to the next digit or to the decimal point. When ‘oFFSt’ has been set to the required value operating the E button will enter the selection and return to the ‘oFFSt’ prompt in the sub-menu. Three operations of the E button will return to the ‘Edit’ function in the main configuration menu. 6.4.11 Access code for listener configuration menu ‘CodE’ Access to the listener configuration menu may be protected by a four digit security code which must be entered to gain access. New instruments are supplied configured with the default code 0000 which disables this protection and allows unrestricted access to the configuration menu. To enter a new access code select ‘CodE’ in the configuration menu by operating the ▼ or ▲ button. To enter the function press P, this will reveal the current access code with one digit flashing. The code may be changed using the ▼ or ▲ button to adjust the flashing digit and the P button to move control to the next digit. When the required code has been selected, press E to enter the selection and return to the ‘CodE’ prompt in the configuration menu. The revised access code will be activated when the transmitter is returned to the display mode. If the access code is lost please contact BEKA associates. 6.4.12 Change from fieldbus listener to fieldbus node ‘tYPE’ This function enables the BA448CF-P to be conditioned as a fieldbus node or as a fieldbus listener. To change the function of the instrument select ‘tYPE’ in the listener configuration menu using the ▼ or ▲ button and press P to enter which will show that the instrument is configured as a fieldbus listener. To change to a fieldbus node press the ▼ or ▲ button which will toggle the display to ‘nodE’.

The instrument will display ‘0000’ with the first digit flashing, using the ▼ or ▲ button set the flashing digit to ‘5’ and press the P button to move control to the next digit which should be set to ‘u’. When the four letters of ‘5urE’ have been entered, operating the E button will result in the instrument restarting in the display mode as a fieldbus node. CAUTION All the instrument’s listener configuration information will be lost when it is changed from a fieldbus listener to a fieldbus node. 6.4.13 Reset the listener to factory defaults ‘rESEt’ The BA448CF-P listener may be reset to the factory defaults that are shown below: Security Code 0000 (disabled) For each of the eight inputs: Decimal point XXX.XX Bar Type Left Bar lower limit 0.0 Bar Upper limit 100.0 Gain 1.0 Offset 0.0 To reset the BA448CF-P listener select ‘rESEt’ in the configuration menu by operating the ▼ or ▲ button. To enter the function press P, this will reveal ‘0000’ with the left hand digit flashing. To prevent accidental use of this function, ‘5urE’ must be entered to confirm that the instrument is to be reset. Using the ▼ or ▲ button set the flashing digit to ‘5’ and press the P button to move control to the next digit which should be set to ‘u’. When the four letters of ‘5urE’ have been entered operating the E button will reset the BA448CF-P to the factory defaults. Any existing configuration and addresses will be lost when the listener is reset.

If a BA448CF-P fails to function during commissioning the following procedure should be followed: Symptom Cause Check: No Display Instrument not correctly connected or powered. 9 to 22V between terminals 1 & 2. Display shows ‘9.9.9.9.9’ with all decimal points flashing; all bargraph segments activated and bargraph scale flashing. Value over-range Variable source Decimal point configuration. Display shows ‘-9.9.9.9.9’ with all decimal points flashing; no bargraph segments activated and bargraph scale flashing. Value under-range Variable source Decimal point configuration Display alternates between value and the word ‘bAd’. Bargraph flashes. Status of fieldbus variable has a quality of ‘BAD’ or a fault state is active. Display has not yet received data. Variable source Fieldbus configuration. Bargraph scale flashes. Variable is outside the limits defined for the bargraph. Bargraph configuration. All display segments activated. Display is initialising. This is normal operation, after a few seconds the firmware version will be displayed prior to entering the display mode. 7.2 Fault finding after commissioning ENSURE PLANT SAFETY BEFORE STARTING MAINTENANCE Live maintenance is permitted on intrinsically safe equipment installed in a hazardous area, but only certified test equipment should be used unless a gas clearance certificate is available. If a BA448CF-P fails after it has been functioning correctly, the table shown in section 7.1 may help to identify the cause of the failure. If this procedure does not reveal the cause of the fault, it is recommended that the instrument is replaced. 7.3 Servicing We recommend that faulty BA448CF-P Fieldbus Indicators be returned to BEKA associates or to our local agent for repair. 7.4 Routine maintenance The mechanical and electrical condition of the instrument should be regularly checked. Initially annual inspections are recommended, but the inspection frequency should be adjusted to suit the environmental conditions. 7.5 Guarantee Instruments which fail within the guarantee period should be returned to BEKA associates or our local agent. It is helpful if a brief description of the fault symptoms is provided. 7.6 Customer comments BEKA associates is always pleased to receive comments from customers about our products and services. All communications are acknowledged and whenever possible, suggestions are implemented.

BA448CF-P indicators are fitted with a blank escutcheon around the liquid crystal display. If specified when the instrument is ordered, this can be supplied printed with units of measurement and a scale for the horizontal bargraph. 8.2 Tag number The BA448CF-P can be supplied with a thermally printed tag number on the rear panel adjacent to the terminals. 8.3 BEKA PROFIBUS PA Display – Fieldbus Interface Guide.
