4 Safety Program Creation - Configuration Example
This chapter describes the procedure for creating the safety program using the
SIEMENS configuration software
TIA Portal V13
and the optional package
S7
Safety Advanced V13
.
The safety program is created with the
Program Editor
in
TIA Portal V13
.
The fail-safe DBs, FBs and FCs are programmed in the
FBD
or
LAD
programming
language. The optional package
Safety Advanced V13
supplied by SIEMENS
provides the user with fail-safe application modules, which can be used in the safety
program.
When generating the safety program, safety checks are performed automatically and
additional fail-safe blocks are integrated for error detection and error reaction. This
ensures that failures and errors are detected and corresponding reactions are
triggered, which keep the F-System in safe status or put it into a safe status.
A standard user program can run in the F-CPU in addition to the safety program. The
co-existence of standard and safety program in the F-CPU is possible, as the safety-
oriented data of the safety program are protected against undesirable influence by
data of the standard user program.
Data exchange between safety and standard user program in the F-CPU is possible
by means of memory bits and through access to the process image of the inputs and
outputs.
Access protection
Access to the F-System
S7 Safety Advanced V13
is protected by two
passwords, the password for the F-CPU and the password for the safety program. The
safety program has an offline and an online password:
● The offline password is part of the safety program in the offline project on the
programming unit.
● The online password is part of the safety program in the F-CPU.
