Modbus on Controllino Maxi

[enfo]

Hi, i’m trying to comunicate using Modbus with Controllino Maxi, using it as slave and PC as Master, but it doesn’t responde.

I’ve tried also use it as Master with a PLC and again no response received.

I tried to use the example sketch and again no response.

Can somebody share me a working test code?
