2.1.5 Address assignment after extension/conversion
A speciality of the CPX terminal is its flexibility. If the demands
placed on the machine change, the equipment fitted 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
modules.
Existing modules are removed or replaced by other mod
ules which have more or fewer input/output addresses.
Manifold sub−bases (CPA) or pneumatic sub−bases
(midi/maxi) for single−solenoid valves are replaced by
manifold sub−bases/sub−bases for double−solenoid
valves or vice versa (see pneumatics manual).
Additional manifold sub−bases (CPA) or sub−bases
(Midi/Maxi) are inserted between existing sub−bases.
The configured addresses of the pneumatic interface are
modified.
