Connecting Sensors/Actuators
7.2 Connecting I/O via PROFIsafe
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:
S $MN_PROFISAFE_IN_ADDRESS[Index]
S $MN_PROFISAFE_IN_FILTER[Index]
S $MN_PROFISAFE_IN_ASSIGN[ 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.
The F net data filter is parameterized in the machine data:
S MD 13300: $MN_PROFISAFE_IN_FILTER[Index] (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 not to be transferred, should be set to
0. The selected F net data signals 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 sig-
nals 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 to the SPL-SGE.
