Blocks
All fail-safe blocks are shown with a yellow background to distinguish them from blocks of the
standard user program.
8.4.1 Program structure
The safety program is accessed by calling up the
F-CALL
from the standard user program.
The
F-CALL
is called up directly e.g. in the cyclic interrupt OB
OB 35
.
Cyclic interrupt OBs have the advantage that they interrupt the cyclic program processing in
OB 1
of the standard user program at fixed time intervals, i.e. in a cyclic interrupt OB the safety
program is called up and processed at fixed time intervals.
After the safety program has been processed, the standard user program is further processed.
8.4.2 F-Runtime Group
To facilitate handling, the safety program consists of an "F-Runtime Group". The F-Runtime
Group is a logic construct consisting of a number of related F-Blocks, which is formed internally
by the F-System.
The F-Runtime Group comprises:
●
one F-Call block F-CALL, "FC1"
●
one F-Program block, to which the F-CALL is assigned, "FC2"
●
further F-FBs
●
several F-DBs
●
F-Periphery-DBs
●
F-System blocks F-SBs
●
automatically generated F-Blocks
