How to select the protocol for rear communication

When the relay is provided with a communication module for the built-in
communication protocols, it allows you to choose the communication protocol for
the rear connection. If the relay is equipped with a protocol-specific communication
module, no communication protocol selections are allowed. The protocol is then
defined by the communication module.
The selected protocol is stored in the non-volatile memory and is therefore activated
automatically after an interruption in the auxiliary voltage.
Select the rear communication protocol as follows:
