You can only access addresses occupied by user data. The other addresses occupied by
the F-modules are assigned for functions including safety-related communication between
F-modules and the F-CPU in accordance with PROFIsafe.
In 1oo2 sensor evaluation, only the lower-value channel of the channels combined by the
1oo2 sensor evaluation can be accessed in the safety program.

Assignment of PROFIsafe Address
PROFIsafe Address
Each fail-safe module has its own PROFIsafe address in addition to the
PROFIBUS/Industrial Ethernet address. Before installing fail-safe modules, you must set the
PROFIsafe address of the F-module on each F-module.
PROFIsafe Address Assignment
The PROFIsafe addresses (F_source_address, F_destination_address) are automatically
assigned when the fail-safe modules are configured in
The F_destination_address is shown in binary format in the "DIP switch setting" parameter in
the object properties for the fail-safe modules in
address from the parameter assignment dialog box and set it on the fail-safe modules using
an address switch.
You can change the configured F_destination_address in
errors, however, we recommend that you use the automatically assigned
F_destination_address.
