Operating Instructions: The module address is displayed in the normal state of the red digital tube. There are two buttons on the panel. The square button sets the module communication address. Short press the square button and release it. The communication address increases by 1. Keep the square button pressed and the module address will go up Increased to 1 after F7 (module display address is hexadecimal) (module address cannot be repeated, the maximum is 247). The triangular button has no effect on the secondary module.
Description of Communication Format The module uses a fixed communication data format: 9600, 8, N, 1.
The module supports the standard modbusrtu protocol. The module uses the function code 06 (write holding register) and the register address is 00 00 (the register address of most configuration software should be increased by 1, for example, the address in the configuration king is 40001).
Module instruction analysis: Write the analog output value of the module, the command frame sent to the module: 03 06 00 00 13 88 85 7E
The first byte 03 is the module communication address, the second 06 is the function code for outputting the analog value, 0000 is the register address, 13 88 is the output analog value, 85 7E is the crc check, and the low bit is first.
The module returns: 03 06 00 00 13 88 85 7E
The first 03 is the module communication address, the second 06 is the function code for outputting the analog value, 13 88 analog value, and 85 7E is the crc test.
The returned data 13 88 is an integer value, 13 88 is converted to decimal 5000, and then multiplied by a fixed coefficient (see Table 1) is the actual output value. For example, the output signal is 4-20ma, 5000 times the coefficient 0.001 is equal to 5.000ma.
