Overview of PROFIsafe F Parameters
Table 45: PROFIsafe F parameters
F Parameters
Default value Description
F_Check_SeqNr No Check
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.
F_Check_iPar
NoCheck
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 iParameter.
When in PROFIsafe V2 mode, the meaning of
this parameter changes and has a
manufacturer-specific meaning.
For the PROFIsafe I/O module, this value is
always set to "NoCheck".
F_SIL
SIL3
The
F_SIL
parameter specifies the required
safety integrity class of the PROFIsafe I/O
module.
The PROFIsafe I/O module support 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_Par_Version
F_CRC_Length
PROFIsafe V1 mode
2-byte CRC
PROFIsafe V2 mode
3-byte CRC
