modulesandspecialfunctionmodules.
Specialfeatures:
V
The modules are automatically addressed.
In general, it is assumed that base units with
8 slots will be used. Dummy slots or missing slots
(in the case of base units with less than 8 slots)
are assigned to 16 addresses.
The automatic addressing can be changed by
means of the function “I/O assignment”.
V
The units are mounted by means of screws or on
a profiled rail with an integrated adapter.

Specialfeatures:
V
A total of three extension base units can be con-
nected to a main base unit.
V
The maximum distance from the first to the last
base unit is 6 m.
Anextensionbaseunitwithapowersupplymodule
mustbeusedinthefollowingcases:
V
If the power consumption of the inserted modules
exceeds the capacity of the power supply module
on the main base unit.
V
If the voltage drops below 4.75 V between the
main base unit and the extension base unit.
