Modbus IP problem

[josep]

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.
