Explanation of the module/channel parameters
5.4.1
F_source_address
Definition
Together, the F-source address "F_source_address" and the F-destination address
"F_destination_address" form the PROFIsafe address. The PROFIsafe address is used for the
unique identification of the F-I/O modules.
The F-source address is a unique address of the fail-safe CPU for the entire network. In S7 F/FH
systems, it is automatically preset with the value "1" and cannot be changed in the properties of
the I/O module.
5.4.2
F_destination_address
Definition
Together, the F-destination address "F_destination_address" and the F-source address
"F_source_address" form the PROFIsafe address. The PROFIsafe address is used for the unique
identification of the F-I/O modules.
Station-wide uniqueness:
• The F-source address "F_source_address" of the F-CPU is unique station-wide. In S7 F/FH
systems, it is automatically preset with the value "1".
• The F-destination address of the F-I/O module is automatically unique station-wide.
To prevent an incorrect parameter assignment, a station-wide unique F-destination address
is automatically assigned when the F-I/O module is placed in HW Config.
If you change F-destination address, the station-wide uniqueness of F-destination address is
automatically checked.
You must assign the F-destination address to the F-I/O module before you commission it.
Note
Requirement for type R1 system redundancy
With type R1 system redundancy for distributed I/O, the left interface module must be
plugged in so that a new F_destination_address can be assigned to the module.
