MODBUS-RTU communication instructions: Function code: 05 is relay output [control relay on / off]. Function code: 06 is to store data [user defined storage data, user defined data, address number, set by the user himself. Generally, it is a useless state.] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Baud rate: 96008 None 1 16 Decimal transmission 16 Decimal receiver Operation steps: 1. software set communication baud rate 2. set the address (the address of the device used for communication, the default address is 01). * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * The set address is: 09 011000000001020009 6656 / / current address 01 modified to 09 001000000001020009 6B C6 / / broadcast address modified to 09 Read address 00030000000185 DB Return： 00030200014444 //01 is the address * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * The meaning of the representative of each byte: [1 address] / / - to - - to - - --- Relay No. 1: 010500010100 9D 9A Byte 1: Address Byte 2: function Byte 34: register address Byte 56: register data Byte 7 8:CRC check / / = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = [1 address] / / - to - - to - - --- Relay No. 0: 01050000 FF 00 8C 3A No. 0 relay closes: 010500000000 CD CA / / - to - - to - - --- Relay No. 1: 01050001 FF 00 DD FA No. 1 relay closes: 010500010000 9C 0A / / - to - -- - ---- Relay No. 2: 01050002 FF 00 2D FA No. 2 relay closes: 010500020000 6C 0A / / - to - -- - ---- Relay No. 3: 01050003 FF 00 7C 3A No. 3 relay closes: 010500030000 3D CA / / - to - -- - ---- Relay No. 4: 01050004 FF 00 CD FB No. 4 relay closes: 010500040000 8C 0B / / - to - - to - - --- Relay No. 5: 01050005 FF 00 9C 3B No. 5 relay closes: 010500050000 DD CB / / - to - -- - ---- Relay No. 6: 01050006 FF 00 6C 3B No. 6 relay closes: 010500060000 2D CB / / - to - -- - ---- Relay No. 7: 01050007 FF 00 3D FB No. 7 relay closes: 010500070000 7C 0B / / - to - -- - ---- Single flipping instruction: No. 0 relay turned over: 010500005500 F2 9A No. 1 relay turned over: 010500015500 A3 5A No. 2 Relay turned over: 01050002550053 5A No. 3 relay turned over: 01050003550002 9A No. 4 relay turned over: 010500045500 B3 5B No. 5 relay turned over: 010500055500 E2 9B No. 6 relay turned over: 01050006550012 9B No. 7 relay turned over: 01050007550043 5B All flipping instructions: 01050000 5A 00 F7 6A / / = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Total extinction: 01 0F 000000080100 FE 95 All bright: 01 0F 0000000801 FF BE D5 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Read the state of the relay: Send: 010100000008 3D CC Return: 010101005188 fully closed relay.
