Modbus RTU :

 

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 :

     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  delay time is 0.1s. The relay will OFF after delay time. So the delay time in this  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  is: 0x001E*0.1=3S.
