2, Relay output signal control commands ( multiple control ) :
Send : 01 0F 00 00 00 08 01 A4FF 2E ( case / 16 hex )
| Data | Bytes | Data Description | Remarks |
| 01 | 1 | Module address | Address range 01-FE |
| 0F | 1 | Function Code | 0F-Write multiple coils |
| 0000 | 2 | Coil address (0x type ) | 0000-Coil start address |
| 0008 | 2 | Write coil length | 0008-Write 8 coil |
| 01 | 1 | Write data byte | 01-Writes a byte of data |
| A4 | 2 | Write data | A4-Write a status output of the coil 8 |
| FF2E | 2 | CRCChecksum | All the data in front of the CRC |
Reception : 01 0F 00 00 00 08 54 0D ( case / 16 hex )
Written data "A4" is converted into a binary number " 10100100 " , from left to right correspond to 8 relay outputs signal status RY8-RY1 , that RY8, RY6, RY3 there is output , no other channel output module after receiving the correct command , make the appropriate action based on the command and response command sent back to the host , indicating successful communication
3, Relay output signal control commands ( individual control ) :
Send : 01 05 00 00 FF 00 8C 3A ( case / 16 hex )
| Data | Bytes | Data Description | Remarks |
| 01 | 1 | Module address | Address range 01-FE |
| 05 | 1 | Function Code | 05-Single Coil |
