8 Safety Creation – Configuration Example
This chapter describes the procedure for creating the safety program using the SIEMENS
SIMATIC Manager
configuration software and the
S7 Distributed Safety
optional
package.
The safety program is created with the
FBD/LAD Editor
in
STEP 7
. The fail-safe FBs and
FCs are programmed in the
F-FBD
or
F-LAD
programming language, while the fail-safe DBs
are created in the F-DB programming language. The
Distributed Safety
F-Library sup-
plied 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 flags and through access to the process image of the inputs and outputs.
Access protection
Access to the F-System
S7 Distributed Safety
is protected by two passwords, the
password for the F-CPU and the password for the safety program. A differentiation is made
between offline and online password for the safety program:
●
The offline password is part of the safety program in the offline project on the programming
device.
●
The online password is part of the safety program in the F-CPU.
