Value
Description
F_CRC_Seed
0
The
F_CRC_Seed
parameter defines the
calculation type of the CRC2. The value of the
parameter must exactly match the value of the
F_Passivation
parameter. If the F I/O module is
to be operated in PROFIsafe Mode V2.4, both
parameters must be set to “0”. If PROFIsafe
Mode V2.6 is to be used, both parameters must
be set to “1”.
Valid combinations are:
F_Passivation
F_CRC_Seed
0
(PROFIsafe Mode
V2.4)
0
1
(PROFIsafe Mode
V2.6)
1
F_Passivation
0
The
F_Passivation
parameter sets the
passivation mode of the F I/O module. If
PROFIsafe Mode V2.4 is to be used, this
parameter and the
F_CRC_Seed
parameter must
be set to “0”. For the type of passivation, the
PROFIsafe V2.4 Passivation Mode
parameter is
used (see Section “Functions” > … > “Module- or
Channel-Granular Passivation in PROFIsafe
Mode V2.4”).
If PROFIsafe Mode V2.6 is to be used, this
parameter and the
F_CRC_Seed
parameter must
be set to “1”. In this case, the F I/O module uses
channel-granular passivation per RIOforFA.
Valid combinations are:
F_CRC_Seed F_Passivation
0 (PROFIsafe
Mode V2.4)
0 (“PROFIsafe V2.4 Passivation
Mode
” parameter is used)
1 (PROFIsafe
Mode V2.6)
1 (channel-granular RIOforFA
passivation)
F_Block_ID
1
The F_Block_ID parameter specifies the format
of the F parameter set. The F I/O module only
s
upports the value “1”.
F_Par_Version
V2 mode
The F_Par_Version parameter specifies the
PROFIsafe version to be used for
communication. The F I/O module only supports
PROFIsafe Mode V2.
