Use the application notes from WAGO!
An overview for using the F I/O module in combination with a safe PLC is
summarized in an application note. This application note is available on the
Internet at www.wago.com under “Service > Downloads > Application Notes ...”.

Overview of PROFIsafe F Parameters
Table 57: PROFIsafe F Parameters
F parameters
Default
Value
Description
F_Check_SeqNr No Check
The F I/O module only supports PROFIsafe Mode
V2. The parameter is not evaluated and must be
on “No Check”.
F_Check_iPar
No Check
For the F I/O module, this value must always be
set to “No Check”.
F_SIL
SIL 3
The
F_SIL
parameter specifies the required
safety integrity level of the F I/O module. The F
I/O module supports SIL3. This value is specified
by the WAGO device description file
(GSD/GSDML).
F_CRC_Length
3-byte CRC
The
F_CRC_Length
parameter specifies the
length of the CRC 2 key to be used in the
PROFIsafe telegram. The required length
depends on the length of the user data to be
transferred.
Valid combinations are:
F_CRC_Seed,
F_Passivation
F_CRC_Length
0, 0
(PROFIsafe V2.4)
3-Byte-CRC
1, 1
(PROFIsafe V2.6)
4-Byte-CRC
