Design (continued)
The load itself and any other compact starters are supplied us-
ing the same connection technique. All the supply and data ca-
bles can thus be laid through the system like a bus. Whereas the
controlgear is switched via the outputs by the 24 V auxiliary
power supply, the inputs are supplied by the AS-Interface data
cable. This principle of separate auxiliary power supplies facili-
tates selective emergency stop concepts.

Addressing
The addressing of the AS-Interface compact starter can still be
used even if it is fully wired, because the module is disconnected
from the AS-Interface network as soon as the addressing con-
nector is inserted.
