Address assignment after extension/conversion

If the requirements for the machine or system change, the CPX terminal can be adapted as required due
to its modular design.
Caution
If the CPX terminal is extended or converted at a later stage, 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 modules which have fewer or
more input/output addresses.
– Interlinking blocks or pneumatic connection blocks for monostable valves are re­
placed by interlinking blocks/connection blocks for bistable valves or vice versa
(è Pneumatics description).
– Additional interlinking blocks or connection blocks are inserted between existing ones.
– Status bits or the I/O diagnostic interface are activated/deactivated.
– The configured addresses of the pneumatic interface are modified.
Please Note
If the configuration of a CPX terminal was changed, new requirements for the CPX ter­
minal that may be necessary must be checked and adjusted, if necessary.
Moreover, it should be noted that the needed address space may increase due to modific­
ation of the CPX terminal and thus the slave addresses of the following slaves in the net­
work must be checked and adjusted if necessary.
