2.1.3 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.
Cauti o n
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:
if additional modules are inserted between existing
modules.
if existing modules are removed or replaced by other
modules which have more or fewer input/output ad
dresses.
if manifold sub−bases (CPA) or pneumatic sub−bases
(Midi/Maxi) for single−solenoid valves are replaced by
manifold bases for double−solenoid valves or vice versa
(see pneumatics manual).
if additional manifold sub−bases (CPA) or sub−bases
(Midi/Maxi) are inserted between existing sub−bases
if status bits or the I/O diagnostic interface is activated/
deactivated.
