Password Protection for F-Systems

4.5
Two Passwords
In addition to the standard password for the F-CPU or CPU, F-systems require a password
for the safety program.
The password for the F-CPU protects the F-systems from unauthorized downloads to the
F-CPU from the engineering system (ES) or programming device (PG).
The password for the safety program protects from unauthorized changes to the
configuration and parameter settings of the F-CPU and F-I/O.
Assigning Passwords
The user assigns the password for the F-CPU in the "Protection" tab in
assigning parameters for the F-CPU.
The user assigns the password for the safety program when programming/configuring the
safety program. Accordingly, a dialog box is displayed automatically when the safety
program is compiled the first time.

Acceptance Test of System

4.6
Who Performs the Acceptance Test?
As a general rule, the acceptance test is performed by independent experts.
Support when Preparing for Acceptance Test
When a system undergoes an acceptance test, all standards relevant to the specific
application must be checked for compliance.
The following special
checking for proper use of the F-system:
• Compare safety programs
• Print safety programs
All data relevant to the acceptance test of the F-system can be accessed in
Manager
User Actions
Actions that are undertaken by the user to prepare the system for the acceptance test
depend on the F-system that is used. For this reason, the procedures are described in the
relevant configuring and programming manuals for S7 Distributed Safety and S7 F/FH
systems under "System Acceptance Test."
