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.,
• F-blocks that are automatically added (F-SBs, automatically generated F-blocks, and the
