753-661/000-004 4FDI 24V PROFIsafe
The F I/O module only supports PROFIsafe
mode V2. The parameter is not evaluated and
must be set to "No Check."
For the F I/O module, this value must always
be set to "No Check."
The F_SIL parameter specifies the required
safety integrity level of the F I/O module. The
F I/O module supports SIL3. This value is
specified by the WAGO device description file
(GSD/GSDML).
The F_CRC_Length parameter specifies the
length of the CRC2 key to be used in the
PROFIsafe telegram. The F I/O module only
supports a 4-byte CRC. This value is specified
by the WAGO device description file
(GSD/GSDML).
The F_CRC_Seed parameter defines the
calculation type of the CRC2. This value is
specified by the WAGO device description file
(GSD/GSDML).
