Parameterization of the F net data transfer
The transfer of F net data in the SPL inputs is parameterized using the following
NCK machine data:
S $MN_SAFE_RDP_ASSIGN[0...m]
S $MN_SAFE_RDP_FILTER[0...m]
NCK--SPL--SGE
:
S
PL assignment:
1st SPL coupling MD $MN_SAFE_RDP_ASSIGN[0] = 001 004
2nd SPL coupling MD $MN_SAFE_RDP_ASSIGN[1] = 033 036
F net data filter:
1st SPL coupling MD $MN_SAFE_RDP_FILTER[0] = 000FH
2nd SPL coupling MD $MN_SAFE_RDP_FILTER[1] = F000H
F net data signals of F_RECVDP:
MD $MN_SAFE_RDP_ID[0]
MD $MN_SAFE_RDP_LADDR[0] = 298
Figure 7-30 F net data transfer F_RECVDP
MD13347 $MN_SAFE_RDP_FILTER
F net data filter
If, on the receiver side, only individual F data signals of the F telegram -- which are
not located one after the other -- are required within the SPL for further processing,
then these can be selected using the F net data filter.
The F net data filter is set using machine data $MN_SAFE_RDP_FILTER[0...m].
Example for NCK parameterization (see Page 7-260)
From the F net data signals of the F telegram, via the F net data filter of the 1st
SPL connection (sub--slot 1), bits 0 to 3 are selected and via the F net data filter of
the 2nd SPL connection (sub--slot 2) bits 12 to 15 are selected. The selected F net
data signals are available as seamless bit field without any gaps (in the example,
with length 4) at the output of the particular F net data filter.
MD13346 $MN_SAFE_RDP_ASSIGN
SPL assignment
For the SPL assignment, the F net data signals selected using the F net data filter
are assigned to the SPL inputs ($A_INSE) as seamless bit field (without any gaps).
The SPL assignment is set using MD $MN_SAFE_SDP_ASSIGN[0...m].
