Hello!
I am trying to write Modbus TCP to a UDC2500. I keep getting exception code 3(Illegal value) with any register. I am writing from function code 6 - write single register.
I have read the manual several times... I must be missing something.
reg. 40003 working setpoint
ANY help would be greatly appreciated!
