F-parameterization
F-parameterization is realized in the properties dialog box under:
Dialog: Properties
Tab: Parameter
Parameters > F-parameters
The F-parameters of the PROFIsafe components are automatically set to the F-monitoring
time of the HW Config and cannot be changed. The displayed values of the F-parameters
● F_source_address
● F_target_address
must be entered into the machine data to parameterize the NCK in a subsequent
parameterizing step.
The value of the F-target addresses should be set at the I/O module (F-module) using the DIL
switches provided.
Note
Failsafe modules for ET 200SP do not have DIL switches that you can use to assign a unique
F-target address for each module. Instead, the F-addresses are permanently saved using the
coding elements of the failsafe modules. For these modules, the PROFIsafe addresses (F-
target addresses) can be assigned from Step 7.

PROFIBUS DP subnet
The PROFIsafe addresses are for unique identification of source and target of safety-related
communications.
The following applies to pure PROFIBUS-DP subnets:
The PROFIsafe target address must be unique network-wide* and station-wide** (system-
wide).
For ET 200S, ET 200pro, ET 200M and ET 200eco, a maximum of 1022 different PROFIsafe
target addresses can be assigned.
For ET 200SP, 65534 PROFIsafe target addresses can be assigned.
* A network comprises one or several subnets. "Throughout the network" means beyond
subnet limits.
** "Station-wide" means for a station with HW configuration (e.g. a Sinumerik 840D sl).
