Modbus TCP slave with LM

[SigmaTec]

Hi all,

I'm scripting a process to simulate power meters with luamodbus functions, and it works wery well when I read all my registers with ModbusPoll scanner. 

But using my script with a real Modbus master product, I have a lot of "connexion errors" (printed by the master).

@IP, port and slaveId are corrects...

Any idea about this ?

Thank's in advance.
All my best.
