in the older hy plugin- what was different in the way they read/write compared to standard modbus?
just wondering if they are doing it the same in the newer model- but using different parameter numbers.
was it something like sending hi byte /low byte in wrong order ?
The older HY used Function 04 and the byte array frame was different. There was only 7 registered to read and was sent in low byte.... below is byte array for out current(2).
01 04 03 02 00 00 51 8e //array sent for Amps in Huanyang plugin
If I remember correctly there was a parameter in HY GT manual for Modbus Standard or Modbus Protocol. I have no idea of the difference but did you try both?
I would try this sting sticking to modbus.
01 03 00 60 00 01 84 14
The status register in manual reads 1001 = 40097
60H = 96
96 + 40001 offset = 40097
Good Luck and don't pull all your hair out.
