NO, no Modbus errors logged....   when I write in the virtual mapped object it seems like the device receive nothing.

For istance, if I set a temperature setpoint to 22, I can see 22 on LM for a while, but when the polling cicle is done, I get the old value again and on the modbus device nothing is actually changed.

Even, I can read everything from it.

It's like a unidirectional comm....
