is possible and also makes sense.
Note
All machine data to connect an F-DI module to the SPL-SGE are associated with one another
through the common index of the machine data:
● $MN_PROFISAFE_IN_ADDRESS[Index]
● $MN_PROFISAFE_IN_FILTER[Index]
● $MN_PROFISAFE_IN_ASSIGN[Index]
● $MN_PROFISAFE_IN_NAME[Index]
F-net data filter
If not all of the F-net data signals of the sub-slots of an F-DI module are required for further
processing within the SPL, then the relevant F-net data signal signals can be selected using
the F-net data filter. Only these are then transferred to the SPL-SGE.
In the output direction, the F-net data filter allows the SPL-SGA ($A_OUTSE), selected using
$MN_PROFISAFE_OUT_ASSIGN[Index], to be distributed to any F-net data signals within the
sub-slot.
The F-net data filter is parameterized in the machine data:
● MD13300 $MN_PROFISAFE_IN_FILTER[0...47] (F-net data filter IN)
Each F-net data signal of the sub-slot is assigned to a filter bit. The filter bits of the F-net data
signals, that are to be transferred to SPL-SGE, should be set to 1. The filter bits of the F-net
data signals, that are
are always transferred to the SPL-SGE as a consecutive bit field (i.e. a bit field without any
gaps).
FFFF FFFFH is the default setting of the filter. This means that all F-net data signals are
transferred.
Example
8 F-net data signals (bits 0...3 and bits 16...19) of the 1st sub slot are filtered from the F-net
data of the F-DI module - and transferred into the SPL-SGE.
● MD10386 $MN_PROFISAFE_IN_ADDRESS[5] = 05 00 0090
● MD13300 $MN_PROFISAFE_IN_FILTER[5] = 000F 000F
● MD10388 $MN_PROFISAFE_IN_ASSIGN[5] = 008 001
