Commissioning
61
PROFIsafe
parameters
General description
The following applies for
CPX-F8DE-P:
Value
F_Check_iPar
Determines whether the indi-
vidual device parameters
(CPX module parameters) are
to be taken into account
when checking the consis-
tency (CRC calculation) of the
F-user data telegram.
–
CPX-F8DE-P does not pro-
vide individual device
parameters.
–
No check
(cannot be
changed)
F_Check_SeqNr
Determines whether the
sequence number is to be
taken into account when
checking the consistency
(CRC calculation) of the F-
user data telegram.
–
CPX-F8DE-P only supports
the V2 mode. The
sequence number is
always included in the
CRC2 test in the V2 mode.
–
Check (cannot
be changed)
F_SIL
The expected safety integ-
rity level (SIL) of the input
module.
–
CPX-F8DE-P supports the
SIL 3 requirement.
–
SIL 3
F_CRC_Length
Communicates the expected
length of CRC2 key to the F-
Host in the safety telegram.
–
This parameter cannot be
changed with CPX-F8DE-P
because the CRC2 key
always occupies 3 bytes.
–
3 CRC bytes
(cannot be
changed)
F_Block_ID
Shows if the data record
for the F_iPar_CRC value has
been extended by 4 bytes.
The parameter F_Block_ID
has the value 1 if the param-
eter F_iPar_CRC is present,
otherwise it has a value of 0.
–
CPX-F8DE-P does not pro-
vide individual device
parameters.
–
0
(cannot be
changed)
F_Par_Version
Displays the PROFIsafe mode
of operation of the device.
The setting 1 corresponds to
PROFIsafe V2 MODE.
–
CPX-F8DE-P operates
exclusively in the PROFI-
safe V2 MODE.
–
1
(cannot be
changed)
F_Source_Add
(PROFIsafe source
address)
Unique PROFIsafe source
address of the F-Host.
–
Unique PROFIsafe source
address of the F-Host.
–
specified by F-
Host
