Hi, I am using a PLC to write and read reqisters from a Cerbo GX over Modbus TCP. I am using register 33 (switch position) to try turn the inverer on and off by sending units 3 or 4 . I have tried this and it seems to think it is off (VRM shows Inverter off) but there is still power so its not completely turning it off. Is there a way that this can be done?
The issue I'm having seems to be an issue with writing to the reister. I can read the register and when i turn the switch off over remote connect, the register reads 4 but when i write a 4 to the register, it doesnt seem to hold the value and nothing will turn off and the register is reading a 3 even though vrm and remote connect are indicating that the multiplus is off.
