Address assignment after extension/
conversion
A special feature of the modular valve terminal
is its flexibility. If the demands placed on the
machine change, the equipment fitting of the
terminal can be modified accordingly.
CAUTION
If the terminal is extended or converted at a
later stage, there may be a shifting of the
input/output addresses. This applies in the
following cases:
•
If one or more pneumatic modules are
added or removed at a later stage (type 03).
•
If a pneumatic module with single valves
is replaced by a new module with double
valves or vice versa (type 03).
•
If additional input/output modules are
inserted between the node and existing
input/output modules.
•
If existing 4-input modules are replaced by
8-input modules or vice versa.
If the configuration of the inputs is modified, the
addresses of the status bits will always be
shifted.
