F_Parameter Definition
F_Check_SeqNr This parameter defines whether
the consecutive number shall be
included in the CRC2. PROFI-
safe V2-mode [3]: consecutive
number has to be always
included in CRC2 generation
F_Check_iPar Manufacturer specific use within
homogeneous systems
F_SIL The different safety functions
using safety-relevant communi-
cation may require different
safety integrity 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
[3].
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 "No F_iPar_CRC within
F_Par_Version Version number of the F-Param-
eter set
F_Source_Add F-Host Source Address. The
F_Source_Add parameter is a
logical address designation that
can be assigned freely but
unambiguously.
F_Source_Add shall not be
equal to F_Dest_Add for the
given F-Device.
