Address assignment after extension/
conversion
A special feature of the modular valve terminal is
its flexibility. If the demands placed on the
machine change, then the number of valves
fitted on the terminal can also be modified.
CAUTION
If extensions or conversions are made to the
terminal at a later stage, this may result in a
shifting of the input/output addresses. This
applies in the following cases:
•
If one or more pneumatic modules is/are
fitted/removed at a later stage (type 03).
•
If an S-type sub-base module with single
solenoid valves is replaced by a D-type
module with double solenoid valves
or vice versa (type 03).
•
If additional input/output stages 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 register structure of the inputs is modified,
the addresses of the status bits will be shifted.
