Information
Addressing is performed depending on version by display, an
external terminal or a PC with the appropriate software (automatic
addressing following chapter).
5.6.1 Automatic addressing
Automatic addressing can be started when the connections “ID1”
and “ID2” for “Addressing” are connected with each other addition-
ally next to the bus connection. I. e. it is no longer necessary to
address every user manually in the network.
