Description
Device Address 1 01H 01H Device, according to setting address
Function Code 1 0FH Write multi holding coil
DO Register Address 2 00 00H Range: 0000-0003, stands for DO0-DO3
Active Relay Qty 2 00 04H Qty: 0-4, stands for how many relays already actived
16CRC Verify 2 54 08H CRC0 CRC1 low byte in front, high behind
Example: Close device 4 DO at same time, then:
Server send: 01 0F 00 00 00 04 01 0F 7E 92
01H= Device address; 0FH= Control multi relay; 00 00H= Relay DO0 starting address; 00 04H= Control 4 relays;
01H= Send data qty; 0FH= Data sent converter to binary 0000 1111 high 4 byte invalid, low 4 byte 1111 sort to
match DO3 DO2 DO1 DO0, 1 stands for close relay, 7E 92H CRC verify.
Device answer: 01 0F 00 00 00 04 54 08
01H= Device address; 0FH= Control multi relay; 00 00H= Relay DO0 starting address; 00 04H= Actived 4 relays;
54 08H CRC verify.
If need to control multi relays at same time, only need to change "Relay Starting Address", "Control Relay Qty",
"Write Data" and calculate "CRC Verify" again.
