General Information On Parametrizing - Festo CPX-AB Series Electronic Manual

3. Analogue input module CPX−4AE−I

3.4.2 General information on parametrizing

3−16
The reaction of the analogue input modules can be
parametrized.
Further information on parametrizing can be found in the
system manual or in the manual for the field bus node.
Due in some cases to necessary calculations, modified para
meters are not valid until they have been thoroughly checked
and saved. Until then, as in the case of invalid parameters,
the previous settings apply.
Depending on the parameter, no valid analogue values are
available for up to max. 30 ms after a value modification.
Special instructions on avoiding parametrizing
faults
In order to avoid parametrizing faults, note the sequence
described below when modifying the following parameters:
Input analogue−value data format
Lower limit channel x
Upper limit channel x
