UTA UTEK MODBUS

[gdimaria]

You need to set the timeout value to max (65535) to disable it. As stated in the documentation:
TEMPO DI SCONNESSIONE
DEFAULT=10 SEC.
65535 DISABILITA LA SCONNESSIONE IN CASO DI MANCATA LETTURA DEI REGISTRI

Alternatively you can set poll interval to be lower than the timeout. But then the value reset will still happen if LM is rebooted and the timeout is reached.

We contacted device assistance and they said to set to NEVER a register to avoid to the automatic refresh to default values.

Now it works, thank so much.
