Figure 2-4: Defining the password for the safety program
Once you have logged in with the password for the safety program, you can
remove the access rights to the safety program as follows:
Log out of Safety Administration
In the menu bar, "Online > Delete access rights"
Close TIA Portal
Collaboration of programmers with and without rights for the user program
Note
Changes to standard DBs that are read/write accessed by the safety program
require a recompilation of the safety program. These standard DBs are not
subject to the access permission for the safety program. Therefore, data
exchange between the F-program and the standard program requires a defined
interface that the programmer of the standard user program does not have to
change during his work.
For more information about this data exchange, please refer to Chapter 3.9.
Access protection for the F-CPU
Access protection for the F-CPU ensures that only authorized persons can
download a safety program to the device or disable safety mode.
The password for the F-CPU is defined in the CPU properties.
Figure 2-5: Defining the password for the F-CPU
Access protection applies only to the appropriate F-CPU. This password is also
used for identification of the F-CPU and must therefore be unique throughout the
network.
