Structure of the Safety Program in S7 Distributed Safety
Representation of Program Structure
The figure below shows the schematic structure of a safety program for S7 Distributed
Safety. For structuring purposes, a safety program consists of one or two F-runtime groups.
The safety program has the following components:
•
F-blocks that are created by the user or selected from F-libraries (e.g.,
Distributed Safety
F-library (V1)).
•
F-blocks that are automatically added (F-SBs, automatically generated F-blocks, and the
F-shared DB)
