A station configured in multi-module mode has as many addresses as it does network connection points.
There is no main address for the station. It will be addressed according to the network that communicates with it.
A multi-module station must always be accessed via the network address that corresponds to the network module enabling entry to the station.
In the following example, station R1 does not have the bridge function between its modules 2, 4 and 5.
-
For a communication from station A to station R1, the address is {13.5}SYS.
-
For a communication from station B to station R1, the address is {12.7}SYS.
