Modbus IP problem - josep - 20.12.2017
Hello, I have an installation with a Seneca Modbut RTU to Modbus IP converter and I try to comunicate it with LM5, In Seneca module I can read modbus RTU variables perfectly but when I try to read this via LM5 only works with some values... In the other values appears a error log like that:
"Invalid Data Adress" and I don't know what's the problem, THX.

Hi,
Did you try to -1 the registers (if register = 2000 => use 1999 in the script to read it), this is most of the time the reason ..
BR,
