Table 45: PROFIsafe F parameters

F Parameters
F_Check_SeqNr No Check
F_Check_iPar
F_SIL
F_CRC_Length
750-666/000-003 4FDI/2FDO 24V/10A PROFIsafe V2 iPar
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.
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".
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).
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
PROFIsafe V1 mode
PROFIsafe V2 mode
Version 1.2.0, valid from HW/SW Version 01/01
WAGO-I/O-SYSTEM 750
F_CRC_Length
2-byte CRC
3-byte CRC
