• Set the IP address of the gateway (router, etc.) used to communicate with other networks. The default value is 0.0.0.0. • Set this value according to the system or the network to which the recorder belongs. In some cases, this setting may not be necessary. • Setting the DNS (Domain Name System) The DNS is a system that correlates the host name/domain name to the IP address. The host name/domain name can be used instead of the IP address when accessing the network. The DNS server manages the database that contains the host name/ domain name and IP address correlation. • On/Off Select On when using the DNS. • P (Primary DNS Server) Set the IP address of the primary DNS server. The default value is 0.0.0.0. • S (Secondary DNS Server) Set the IP address of the secondary DNS server. The default value is 0.0.0.0. If the primary DNS server is down, the secondary server is used to search the host name and IP address correlation. • Suffix_P (Primary Domain Suffix), Suffix_S (Secondary Domain Suffix) When the recorder searches another server using the DNS server, the domain name of the recorder is appended to the host name as a possible domain name if it is omitted. If the IP address corresponding to the server name is not found on the DNS server, then it may be that the system is configured to use another domain name for searching. This alternate domain name is specified as the domain suffix. • Set the domain suffix using up to 64 alphanumeric characters. • Up to two domain suffixes can be specified (primary and secondary). • Saving the Settings To activate the settings made in the Basic Setting mode, the settings must be saved. 2.3 Configuring the Ethernet Interface

WARNING To prevent the possibility of electric shock, connect the cables with the power turned OFF. Note • Connect the RD pin to the SD (TD) pin on the PC (converter) end and the SD pin to the RD pin on the PC end. • The two-wire system can be used only when using the Modbus protocol. Connection Example with a Host Computer A connection can be made with a host computer having a RS-232, RS-422A, or RS-485 port. • In the case of RS-232, a converter is used. • For recommended converters, see “Serial Interface Converter” on the next page. • The two-wire system can be used only when using the Modbus protocol. For the configuration procedure, see section 3.5 • Four-Wire System Generally, a four-wire system is used to connect to a host computer.

In the connection example, the shield of the cable is connected only to the recorder’s ground (one-sided grounding). This is effective when there is a difference in the electric potential between the computer’s ground and the recorder’s ground. This may be the case for long distance communications. If there is no difference in the electric potential between the computer’s ground and the recorder’s ground, the method of connecting the shield also to the computer’s ground may be effective (two-sided grounding). In addition, in some cases, using two-sided grounding with a capacitor connected in series on one side is effective. Consider these possibilities to eliminate noise. • When using the two-wire type interface (Modbus protocol), the 485 driver must be set to high impedance within 3.5 characters after the last data byte is sent by the host computer. • Serial Interface Converter CAUTION Some converters have FG and SG pins that are not isolated. In this case, do not connect anything to the converter’s FG and SG pins (unlike the figure on the previous page). Especially in the case of long distance communications, the potential difference that appears may damage the recorder or cause communication errors. For converters that do not have the SG pin, they can be used without using the signal ground. For details, see the manual that came with the converter. On some non-recommended converters, the signal polarity may be reversed (A/B or +/- indication). In this case, reverse the connection. 3.2 Terminal Arrangement and Signal Names and the Connection Procedure of the RS-422A/485 Communication Interface

converter in order to prevent collisions of transmit and received data. When using the recommended converter, the driver is controlled using the RS (RTS) signal on the RS- 232. • When Instruments That Support Only the RS-422A Interface Exist in the System When using the four-wire system, up to 32 recorders can be connected to a single host computer. However, this may not be true if instruments that support only the RS- 422A interface exist in the system. When the instrument that support only the RS-422A interface exist in the system The maximum number of connection is 16. Some of OMEGA’s conventional recorder only support the RS-422A driver. In this case, only up to 16 units can be connected. Note In the RS-422A standard, 10 is the maximum number of connections that are allowed on one port (for a four-wire system). • Terminator When using a multidrop connection (including a point-to-point connection), connect a terminator only to the recorder on the end of the chain. In addition, turn the terminator on the host computer ON (see the computer’s manual). If a converter is being used, turn ON its terminator. The terminator must be attached externally to the recommended converters. 3.2 Terminal Arrangement and Signal Names and the Connection Procedure of the RS-422A/485 Communication Interface

3.3 The Bit Structure of One Character and the Operation of the Receive Buffer The Bit Structure of One Character The serial interface on the recorder communicates using start-stop synchronization. In start-stop synchronization, a start bit is added every time a character is transmitted. The start bit is followed by the data bits, parity bit, and stop bit. (See the figure below.) Data bit (7 or 8 bits) 1 character Stop bit Parity bit Even, Odd, or None Start bit Circuit idle state Return to the idle state (dotted line) or the start bit of the next data character (solid line) Receive Buffer and Received Data The data received from the PC is first placed in the receive buffer of the recorder. When the received buffer becomes full, all of the data that overflow are discarded.

instrument is given below. ASCII codes (see appendix 1) are used for the character codes. For the Maintenance/Test command syntax, see section 4.9. For the Instrument Information server command syntax, see section 4.10. Command name Parameter ? Terminator Delimiter Sub delimiter SR 02,SKIP;SR 03,VOLT,2V,-1500,1800 Parameter (02 SKIP·····1800) Delimiter (,) Command name (SR) Sub delimiter (;) Command example • Command Name Defined using two alphabet characters. • Parameter • Command parameters. • Set using alphabet characters or numerical values. • Parameters are separated by delimiters (commas). • When the parameter is a numerical value, the valid range varies depending on the command. • Spaces before and after of the parameter are ignored (except for parameters that are specified using an ASCII character string (unit, tag, and message string), when spaces are valid.) • You can omit the parameters that do not need to be changed from their current settings. However, delimiters cannot be omitted. Example SR 01,,2V If multiple parameters are omitted and delimiters occur at the end of the command, those delimiters can be omitted. Example SR 01,VOLT,,, → SR 01,VOLT • The number of digits of the parameters below is fixed. If the number of digits is not correct when entering the command, a syntax error results. • Date YY/MM/DD (8 characters) YY: Year (Enter the lower two digits of the year.) MM: Month DD: Day • Time HH:MM:SS (8 characters) HH: Hour MM: Minute SS: Second • Channel number: 2 characters (Example: 01, 0A) • Relay number: 3 characters (Example: I01) • Communication input data: 3 characters (Example: C02) • Constants used in the computation function (/M1 option): 3 characters (Example: K03) • Remote control (/R1 option) input terminal status: 3 characters (Example: D04) Chapter 4 Commands

• By placing a query after a command or parameter, the setting information of the corresponding command can be queried. Some commands cannot execute queries. For the query syntax of each command, see sections 4.4 to 4.7. Example 1 SR[ p1]? SR? or SR p1? can be executed. Example 2 SA[ p1[,p2]]? SA?, SA p1?, or SA p1,p2? can be executed. • Delimiter • A comma is used as a delimiter. • Parameters are separated by delimiters. • Sub Delimiter • A semicolon is used as a sub delimiter. • By separating each command with a sub delimiter, up to 10 commands can be specified one after another. However, the following commands and queries cannot be specified one after another. Use them independently. • Output commands other than BO, CS, and IF commands. • YE command • Queries * If there are consecutive sub delimiters, they are considered to be single. In addition, sub delimiters at the front and at the end are ignored. Example ;SR01,VOLT;;;SR02,VOLT; is taken to be SR01,VOLT;SR02,VOLT. • Terminator (Terminating Character) Use either of the following two characters for the terminator. • CR + LF (0DH 0AH in ASCII code.) • LF (0AH in ASCII code.) Note • The total data length from the first character to the terminator must be less than 2047 bytes. In addition, the character string length of 1 command must be less than 512 bytes. • Commands are not case sensitive (with the exception of user-specified character strings). • All the commands that are listed using sub delimiters are executed even if one of the commands is erroneous. • Spaces that are inserted before and after a parameter are ignored. However, if spaces are inserted before a command, after a sub delimiter, or after a query, an error occurs. Response The recorder returns a response (affirmative/negative response) to a command that is separated by a single terminator.* The controller should follow the one command to one response format. When the command-response rule is not followed, the operation is not guaranteed. For the response syntax, see section 5.1. * The exceptions are the RS-422A/485 dedicated commands (see section 4.8). Note When using the RS-422A/485 interface, allow at least 1 ms before sending the next command after receiving a response. Otherwise, the command may not be processed correctly. 4.1 Command Syntax

Execution Modes and User Levels Execution Modes The recorder has two execution modes. Each command is specified to be used in a particular execution mode.

The following figure illustrates the status information and filter on the recorder. Status information Filter Condition register 4 bytes 4 3 2 1 4 3 2 1 • When a status indicated on the following page is entered, the corresponding bit in the condition register is set to “1.” The logical AND of the condition register and the filter becomes the status information. • The IF command can be used to set the filter. • The IS command is used to output the status information. Status information 1 and 2 are cleared when they are output. Status information 3 and 4 are not cleared when it is output, and remains at “1” while the event is occurring. • When multiple connections are up, filters can be specified for the individual connection. Therefore, the status information can be held for each connection. Chapter 6 Status Information

The following four groups of status information are output in response to a status information output request using the IS command.

The recorder has a dedicated internal memory for outputting measured/computed data. This memory is structured as a FIFO (First-In-First-Out). Measured/computed data are constantly acquired to the internal memory at the specified acquiring interval (FIFO acquiring interval, set with the FR command). By using this function, it is possible to read measured/computed data that have been saved at the specified intervals regardless of the frequency at which the PC periodically reads the measured/computed data. The following example shows the case when the acquiring interval is 1 s and the buffer capacity is for 8 intervals. Most recent acquire Position: WP Previous read Position: RP1 Current read Position: RP2 Block 1 2 3 4 5 6 7 Block 8 • Acquiring of the measured/computed data • The measured/computed data are acquired to the internal memory at 1 s intervals. • Measured/computed data are acquired to blocks 1 through 8 in order. After acquiring to block 8, the next acquiring operation returns to block 1. • Reading the measured/computed data (FF GET command is used, logging output) Outputs the data from the next to the previous read position (RP1) to the most recent acquire position (WP). In this example, more than 2 s has elapsed from the previous read operation. Therefore, data in blocks 5 and 6 are output. • Reading the measured/computed data (FF GETNEW command is used, output of the most recent value) Output the specified number of blocks of FIFO data back starting from the recent acquire position (WP). In this example, if you specify the number of blocks to “5,” data in blocks 2 to 6 are output. The buffer capacity varies depending on the model. Pen model: 240 intervals (30 s at an acquiring interval of 125 ms) Dot model: 60 intervals (60 s at an acquiring interval of 1 s)
