F_Parameter Definition
F_Check_SeqNr This parameter defines whether
the consecutive number shall be
included in the CRC2. PROFIsafe
V2-mode
number has to be always included
in CRC2 generation.
Note:
F_Check_SeqNr is not shown in
the F-Parameter configuration for
SM560-S-FD-1 and
SM560-S-FD-4.
F_Check_iPar Manufacturer-specific use within
homogeneous systems
F_SIL Different safety functions using
safety-relevant communication
may require different safety integ-
rity levels. The F-Devices are able
to compare their own assigned SIL
with the configured SIL (F_SIL). If
it is higher than the SIL of the con-
nected F-Device, the "device
failure" status bit is set and a safe
state reaction is triggered
F_CRC_Length Depending on the length of the
F I/O data (12 or 123 octets) and
the SIL level, a CRC of 2, 3, or 4
octets is required
F_Block_ID Type identification of parameters
F_Par_Version Version number of the F-Param-
eter set
