7 < 1. Overview of the Communications Function> 1 1. Overview of the Communications Function The DTSX200 supports communications based on the Modbus protocol via builtin Ethernet and RS-232C ports as communications interfaces. Using Modbus communications, a client/master can configure, control, as well as retrieve status information and measurement data from a remote DTSX200. The figure below shows an example system configuration. PC PC PC STARDOM,CENTUM Control device Modbus/TCP Modbus/TCP Modbus/TCP Modbus/TCP Ethernet DTSX200 RS-232C Modbus Serial (ASCII, RTU) If connection to the DTSX200 is by Ethernet, the Modbus/TCP communications protocol is used, the DTSX200 runs as a Modbus/TCP server and can connect to a maximum of four client devices. If connection to the DTSX200 is by RS-232C, the DTSX200 runs as a slave device and communicates one-to-one with a master device. Both the RTU and ASCII serial transmission modes are supported. For RS-232C communications, a slave address must be defined for the DTSX200.

17 < 4. Modbus Communications Protocol> Modbus Communications Protocol 4.1. Overview In a communications system based on the Modbus protocol, the master initiates a transaction and the slave responds to it. The communications protocol is as follows: 1) A master sends a request message to slaves. 2) Each slave compares the device number in the received message to its own device number. 3) If the device numbers match, the slave sends a response message. 4) If the device numbers do not match, the slave discards the received request message and waits for the next request message. By specifying a device number in a request message, a master can communicate with a specific slave even when multiple slaves are connected to the same line Message Structure Each request message or response message comprises four fields, namely a device number, a function code, a data field and an error check code, which are transmitted sequentially in the given order. Modbus defines two serial transmission modes, namely, the RTU mode and the ASCII mode, with different message formats. The ASCII mode permits only data comprising ASCII characters 0-9 and A-F. Device number (1 byte) Function code (1 byte) Data (n bytes) Error check code (CRC) (2 bytes) RTU mode Start (1 character): colon (:) Device number (2 characters) Function code (2 characters) Data (n characters) Error check code (LRC) (2 characters) End (2 characters): CR+LF ASCII mode Each message field is described in more details below Device Number The device number specifies a slave. Only the DTSX200 with a matching device number will process the request message Function Code The function code specifies the function to be executed by the slave. SEE ALSO For more details on the function code, see Section 4.4, Function Codes Data The data field contains data required for executing the function defined by the function code. The data structure varies with the function code. Each DTSX200 setting is assigned a unique register number. To read or write a setting, specify its register number. Register numbers must be specified as relative addresses in transmitted messages.

18 < 4. Modbus Communications Protocol> 12 The relative address of a register is given by the formula: Relative address = Last 5 digits of the register number 1 For example, to specify register number as a parameter for a function code, you should specify relative address in the message: Relative address = (last 5 digits of ) 1 = Error Check Code The error check code is used for detecting message errors (bit changes), if any, introduced during signal transmission. CRC (Cyclic Redundancy Check) is used in RTU serial transmission mode. LRC (ngitudinal Redundancy Check) is used in ASCII serial transmission mode Slave Response Normal Response If no error occurs in relation to the function requested in a properly received request message, the slave creates and returns a normal response message. The message structure is as described in Section 4.2. The content of the data field varies with the function code. SEE ALSO For details on the function code, see Section 4.4, Function Codes Exception Response If a request message contains a non-transmission-related error (such as a non-existent function code), the slave creates and returns an error response message without executing the request. The figure below shows the structure of an error response message. In an error response, the function code is 80H higher than the function code of the original request. Device number Function code+80 H Error code Error check code (CRC) RTU mode Start (1 character): colon (:) Device number Function code+80 H Error code Error check code (LRC) End (2 characters): CR+LF ASCII mode The error codes are listed in the table below. Table: Error Codes Error Code Error Description 01 H Invalid function code The specified function code is non-existent. Check the specified function code. 02 H Invalid address for coil or register The specified relative address of a register number is not allowed for the specified function code. 03 H Invalid number of registers The specified number of registers is too large and covers a range containing non-existent register numbers.

19 No Response < 4. Modbus Communications Protocol> 13 A slave ignores a request message and returns no response if: - The device number specified in the request message does not match slave s own device number; - The error check code does not match; or - A transmission error (such as a parity error) is detected Function Codes In the Modbus protocol, each function code can only act on certain allocated register numbers. The table below shows the mapping between function codes and register numbers for the DTSX200. Table: Mapping between Function Codes and Addresses Function Code Register Number Number Function Object Number Description 03 H Read (contiguous) Holding registers 4XXXXX Read-write word data 04 H Read (contiguous) Input registers 3XXXXX Read-only word data 06 H Write Holding register 4XXXXX Read-write word data 10 H Write (contiguous) Holding registers 4XXXXX Read-write word data

25 6. Address Map 6.1. Handling of Fractional Data < 6. Address Map> 19 Some DTSX200 settings allow fractional values but transmission of fractional values in messages is not allowed. In the address map tables in the following pages, a setting parameter allowing fractional values is specified with its fixed number of decimal places. When handling fractional data, calculate its proper value using its fixed number of decimal places as shown in the following examples. Example 1: Reading the fiber length setting for zone 1 of channel 1 (register number: ) If the DTSX200 returns a value of 1000 for this parameter, which has 1 decimal place, the fiber length of zone 1 of channel 1 is given by: = Example 2: Writing the fiber length setting for zone 1 of channel (register number: ) To set the fiber length of zone 1 of channel 1 to 100.0, the value to be written to the DTSX200 for this parameter, which has 1 decimal place, is given by: 100.0x10 = Holding Register Address Map List of Holding Registers Register Number Function to Execution control functions Data conversion function Temperature calibration function Initialization function Measurement sequence control settings Measurement sequence table settings Measurement condition settings Fiber settings Channel settings Alarm settings Tag data settings Data conversion function Data conversion function selection Header settings LAS data conversion Conversion and transmission settings Channel number for latest measurement data Latest measurement Tag data data monitoring area Alarm information Individual channel measurement data monitoring area Measurement data information
