Connecting Sensors/Actuators
7.2 Connecting I/O via PROFIsafe
Note
Fail--safe 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 target addresses
are permanently saved using the coding elements of the fail--safe modules. For
these modules, the PROFIsafe addresses (F target addresses) can be assigned
from the Step7.

Warning
!
The PROFIsafe addresses are for unique identification of source and target of
safety--related communications.
For pure PROFIBUS DP subnets, the following applies:
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 consists of one or more subnets. "Network--wide" means across
subnet boundaries.
** "Station--wide" means for a station with HW configuration (e.g. a Sinumerik
840D).
F parameters: F_source/target_address
F_source_address
The F--source--address is the decimal PROFIsafe address of the F master allo-
cated automatically by HW Config. The F_source_address is formed from the
"basis for PROFIsafe addresses" plus the PROFIBUS address of the
PROFIBUS--DP interface.
Note
To clearly define the PROFIsafe communication, the PROFIsafe address of the
F master – assigned by HW Config – must be saved in the F master. To do this,
the PROFIsafe address of the F master must be converted from decimal into
hexadecimal and entered into the machine data of SINUMERIK 840D sl. See
Chapter 7.2.4 "Parameterizing the F master (NCK)".
F_target_address
The F_target_address is the decimal PROFIsafe address of the F module auto-
matically allocated by HW Config (the user can change this).
