MODBUS RTU communication instruction: Modbus RTU instruction Baud rate: 96008 NONE 1 The relay module can have multiple network communication, and the communication address can be set by serial port instruction. (communication instructions provided by SkyDrive) Relay module factory default communication address fixed to 1, serial assistant operation instructions: Note: the following specific test instructions are passed through the network Instruction function: 1. set address to 2. read address 3. read software version 4. read the hardware version Output instructions: 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.
