Modbus RTU Command
1. Suppose the device address is 0xFF so return 00 10 00 00 00 01 02 00 FF EB 80 and the 9th byte is device address.
2. Turn ON CH_1 Relay (Normal Mode)
Send:FF 05 00 00 FF 00 99 E4
Return:FF 05 00 00 FF 00 99 E4
Note_1:The 3rd and 4th byte are relay addresses. So it can be 0x0000, 0x0001, 0x0002, 0x0003.
Note_2:The 5th and 6th byte are relay data. 0xFF00 means turn ON relay and 0x0000 means turn OFF relay.
3. Turn OFF CH_1 Relay(Normal Mode)
Send:FF 05 00 00 00 00 D8 14
Return:FF 05 00 00 00 00 D8 14
4. Turn ON CH_2 Relay(Normal Mode)
Send:FF 05 00 01 FF 00 C8 24
Return:FF 05 00 01 FF 00 C8 24
5. Turn OFF CH_2 Relay(Normal Mode)
Send:FF 05 00 01 00 00 89 D4
Return:FF 05 00 01 00 00 89 D4
6. Turn ON All relays
Send:FF 0F 00 00 00 08 01 FF 30 1D
Return:FF 0F 00 00 00 08 41 D3
7. Turn OFF All relays
Send:FF 0F 00 00 00 08 01 00 70 5D
Return:FF 0F 00 00 00 08 41 D3
8. Set device address to 0x01
Send:00 10 00 00 00 01 02 00 01 6A 00
Return:00 10 00 00 00 01 02 00 01 6A 00
Note:The 9th btye is device address.
9. Set device address to 0xFF
Send:00 10 00 00 00 01 02 00 FF EB 80
Return:00 10 00 00 00 01 02 00 FF EB 80
10. Read device address
Send:00 03 00 00 00 01 85 DB
Return:00 03 02 00 FF C5 C4
Note:The 5th btye is device address.
11. Read relay status
Send:FF 01 00 00 00 08 28 12
Return:FF 01 01 01 A1 A0
Note:The 4th means which one relay. 0 means OFF and 1 means ON.
12. Read optocoupler input staturs
Send:FF 02 00 00 00 08 6C 12
Return:FF 02 01 01 51 A0
Note:The 4th means which one input. 0 means low level signal input and 1 means high level signal input.
13. Set baud rate 4800bps
Send:FF 10 03 E9 00 01 02 00 02 4A 0C
Return:FF 10 03 E9 00 01 C5 A7
Note:The 9th btye is baud rate value. 0x02 is 4800bps. 0x03 is 9600bps. 0x04 is 19200bps.
14. Set baud rate 9600bps
Send:FF 10 03 E9 00 01 02 00 03 8B CC
Return:FF 10 03 E9 00 01 C5 A7
15. Set baud rate 19200bps
Send:FF 10 03 E9 00 01 02 00 04 CA 0E
Return:FF 10 03 E9 00 01 C5 A7
16. Turn ON CH_1 Relay(2S Flashing Mode)
Send:FF 10 00 03 00 02 04 00 04 00 14 C5 9F
Return:FF 10 00 03 00 02 A4 16
Note_1:The 3rd and 4th byte are relay addresses. So CH1~CH4 can be 0x0003, 0x0008, 0x000D, 0x0012.
Note_2:The 10th and 11th byte are delay time in second. The minimum delay time is 0.1s. The relay will OFF after delay time. So the delay time in this command is:0x0014*0.1=2S.
17. Turn OFF CH_1 Relay(3S Flashing Mode)
Send:FF 10 00 03 00 02 04 00 02 00 1E A5 99
Return:FF 10 00 03 00 02 A4 16
Note:Relay will ON after delay time. So the delay time in this command is:0x001E*0.1=3S.
