2.1.3 Address assignment after extension/conversion

2-24
A special feature of the CPX terminal is its flexibility. If the
requirements placed on the machine change, the equipment
on the CPX terminal can also be modified.
Caution
If the CPX terminal is extended or converted at a later
stage, the input/output addresses may be shifted. This
applies in the following cases:
– Additional modules are inserted between existing mod-
ules.
– Existing modules are removed or replaced by other mod-
ules which have fewer or more input/output addresses.
– Interlinking blocks (CPA) or pneumatic connection
blocks (Midi/Maxi) for monostable valves are replaced
by interlinking blocks for bistable valves or vice versa
(see pneumatics description).
– Additional interlinking blocks (CPA) of manifold blocks
(Midi/Maxi) are inserted between existing ones.
– The configured addresses of the pneumatics interface
are modified.
Note
If the configuration is modified, the addresses of the status
bits as well as those of the I/O diagnostics interface will
also be shifted!
