Notes on the table
There is a separate table for each manual that describes the technical
specifications of the signal modules of the S7-300 product family.
The "Behavior of the Inputs/Outputs" column indicates the behavior of the
inputs/outputs when reparameterization is carried out in RUN mode, provided they
are not affected by reparameterization.

Remedy:
•
Only reparameterize when there is no

•
Remove the module, and then plug it in
