Overview of PROFIsafe F Parameters

Table 51: PROFIsafe F Parameters

F Parameters
F_Check_SeqNr No Check
F_Check_iPar
F_SIL
F_CRC_Length
Default Value Description
When in PROFIsafe V1 mode, the
F_Check_SeqNr parameter determines
whether the consecutive number of the
PROFIsafe telegrams should be included in
the consistency check (CRC 2 calculation) of
the PROFIsafe telegram.
Because the available safe PLC controllers
only support "No Check", this parameter must
be set accordingly.
When in PROFIsafe V2 mode, the parameter
has no effect.
When in PROFIsafe V1 mode, this parameter
only determines whether the CRC 3 should go
into calculating CRC 1 as the starting value.
CRC 1 is the CRC above the F parameter.
CRC 3 is the CRC above the individual
NoCheck Parameter.
When in PROFIsafe V2 mode, the meaning of
this parameter changes and has a
manufacturer-specific meaning.
For the F-I/O-Module, this value is always set
to "NoCheck".
The F_SIL parameter specifies the required
safety integrity class of the F-I/O-Module.
SIL3 The F-I/O-Module support SIL3. This value is
specified by the WAGO device description file
(GSD/GSDML).
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.
3-byte CRC

F_Par_Version
