Hi,
I try to control inverter hitachi x200 via modbus using PC and unitronics V530.
To test connection i use Modbus Tester and i can freely turn inverter ON/OFF and change frequency, but I am limited to see only first 8 registers. When i choose to view data of more registers program send exception error - 02 illegal address, and I have response only from read holding registers. I need a lot more than that so I ask you for your help. It may be connection problem, because when I use V530
(PC -> PLC -> inverter)
I have some connection errors - it retries connection all the time, so if anyone had tried something like this, I would be grateful for any advice.
Best regards, Jacek
