Continue the software description "04 (0x04) Read input register" Request valid register start address 0 Number of valid registers 1 Response byte count 2 Value register input status bit 0.. 3 "03 (0x03) Read holding register" Request invalid register start address 0.. 1 or 66 Number of valid registers 2 or 1 Response function code, byte count, register value register 0: value register 1: value register 66 Time constant for communication monitoring. The register value=0 (0x0000) has no communication monitoring. All other values are used for communication monitoring. The solution is 10 ms. 0x0000 to 0xFFFF=>0 to 655.35 seconds=10.9 minutes bit information 0 0=state relay 1 closed 1=state relay 2 closed 1=state relay 2 switched through bus 1 0=relay 1 switched through manual control 0=relay 2 bit information switched through bus 2 0=initial state after reset or communication control relay 1 closed 1=initial state after reset or communication control relay 1 1 0=reset or communication control relay 2 closed 1=initial state after reset, Or the communication control relay 2 requests the register address 0 or 1 or 66 register value bits 0 – 1 according to the table or the above request "16 (0x10) writing multiple registers" to request the valid register starting address 0 or 1. The number of valid registers is 1.2 bytes count 2 x the number of register values x 2 bytes bits 0 – 3 according to the table to respond to the function code, register starting address
Number of registers 9.2 The bit rate set using the Modbus command parity sum bit rate is the same as the value set through the address switch. If the value of parity or bit is 0, it is not set or stored. The register contents are stored in EEPROM. "06 (0x06) Write to Single Register" requests valid register address 0x41 (65) valid register value 2 byte bits 15-8: magic number 0x53=83 to prevent accidental writing. Use this number only for further analysis of the command. Echo response of frame request example: write single register address Hi 0x00 register address Lo 0x41 bit rate and parity (65) register content Hi 0x53 magic number register content Lo 0x15 parity check from the setting (18) function 0x06 of rotary switch at address 0x12, Because this may cause problems: - Other manufacturers' devices may have a register under this address for different purposes, and then operate in the wrong way- No feedback from each device. Therefore, the control cannot immediately identify whether the command was received correctly.
