Product Information on the Manual
A5E00201782-02
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.

SF LED shines:
If there was a pending diagnosis before
reparameterization, the SF LEDs (on the
CPU, IM, or module) may still be shining

Supply the last valid
process value before
reparameterization, the SF LEDs (on the
CPU, IM, or module) may still be shining
although there is no longer a pending
diagnosis and the module is working

Remedy:
• Only reparameterize when there is no
pending diagnosis on the module, or

pending diagnosis on the module, or
• Remove the module, and then plug it in
again
