Configuring PROFIsafe

The safety functions can be controlled via PROFIBUS DP using the PROFIsafe profile.
Telegrams are available for the data exchange with the higher-level controller which enable
the triggering of the safety functions in the converter by the controller as well as the feedback
of the status of the safety functions from the converter to the controller.
PROFIsafe address type for SINAMICS Integrated and NX
SINAMICS Integrated, as integrated subcomponent of the NCU as well as of NX modules
are considered as F-I/O of PROFIsafe address type 1 in the TIA Portal. (This address type is
also valid for other SINAMICS drives.)
For the I/Os of PROFIsafe address type 1, the uniqueness of the PROFIsafe address is only
ensured by the F-destination address (F_DEST_ADD). The F-source address has no effect
on the uniqueness of the PROFIsafe address.
The F-destination address must therefore be unique throughout the network and CPU (see
section "Rules for address assignment").
Configuration of safety telegrams
Safety telegrams can be configured in the properties of SINAMICS Integrated or NX under
"Cyclic data traffic".
Safety-relevant parameters, such as the fields for PROFIsafe addresses, are displayed if a
PROFIsafe telegram was added:
● The telegram configuration of SINAMICS Integrated or NX modules is automatically
adapted when you activate the Safety Integrated plus (F-PLC) mode. PROFIsafe
telegrams are added here (SIEMENS telegram 902).
● For additionally connected drive units, add a PROFIsafe telegram in the device overview.
Unique PROFIsafe addresses
For safe operation, you must check whether the used PROFIsafe addresses are unique
before starting the communication.
The uniqueness of the PROFIsafe address is only ensured by the fail-safe destination
address. The PROFIsafe address must be unique throughout the network and the CPU.
You can configure the fail-safe destination address under "Cyclic data exchange" in the
properties of the PROFIsafe telegrams (Safety actual value or Safety setpoint value).
