10.7.6 Configuration of the PROFIsafe addresses (peripherals)
The PROFIsafe addresses (F-source address, F-destination address) are used to uniquely
identify the source and the destination.
Note
Problem solution for the 27220, 27221 alarms (Safety Integrated (SPL))
● Alarm27220: "PROFIsafe: Number of NCK-F modules (6) <> number of S7-F modules (0)"
● Alarm27221: "PROFIsafe: NCK-F module MD$MN_PROFISAFE_IN_ADDRESS[0]
unknown or"PROFIsafe: NCK-F module MD $MN_PROFISAFE_OUT_ADDRESS[0]
unknown"
Even if you reuse the existing machine data settings (e.g. using an existing SINUMERIK
archive), you can change the PROFIsafe addresses. In this case, alarms 27220 and 27221 are
displayed in SINUMERIK Operate.
You must also modify or augment the details in MD10385, as described here.
Rules for configuring F-source addresses
When Safety Integrated (SPL) is used, you must enter the associated F-source addresses in
the
MD10385[0..2]. A maximum of three different F-source addresses are permitted throughout
the system.
You can view the assigned F-source addresses in the PLC properties under "Fail-safe > F-
source addresses".
The assignment methods of the F-source address in the TIA Portal depend on the used F-
peripherals, not on the controller or the used Safety Integrated mode:
● F-peripherals based on the device description file:
The configured F-source address can be set in the properties of the module under
"PROFIsafe > F_Source_Add".
● F-peripherals for PROFIsafe address type 1 (e.g. F-module ET 200S)
The F-source address has the constant value "1".
(The unique identification is made using the set F-destination address.)
● F-peripherals for PROFIsafe address type 2 (e.g. F-module ET200SP)
The F-source address is assigned depending on the PROFIsafe base address (can be set
in the PLC properties under "Fail-safe > F-parameters").
The "Basis for PROFIsafe addresses" parameter differs in its effect from STEP 7 V5.x. This
parameter is not used in the TIA Portal to influence the F-source address for fail-safe I/O of the
PROFIsafe address type 1 (e.g. ET200S).
