Program structure of the safety program (S7-1500)

Representation of program structure
For structuring purposes, a safety program consists of one or two F-runtime groups.
Each F-runtime group contains:
● F-blocks that you create using FBD or LAD or that are inserted from the project library or
global libraries
● F-blocks that are added automatically (F-system blocks F-SBs, automatically generated F-
blocks, F-runtime DB, and F-I/O DBs)
The following diagram shows the schematic structure of a safety program and/or an F-runtime
group for an F-CPU S7-1500.
