Parameterization of the F net data transfer
The transfer of the SPL outputs in the F net data is parameterized using the follo-
wing NCK machine data:
S $MN_SAFE_SDP_ASSIGN[0...m]
S $MN_SAFE_SDP_FILTER[0...m]
NCK--SPL--SGA
:
SPL assignment:
1st SPL coupling MD $MN_SAFE_SDP_ASSIGN[0] = 001 004
2nd SPL coupling MD $MN_SAFE_SDP_ASSIGN[1] = 033 036
F net data filter:
1st SPL coupling MD $MN_SAFE_SDP_FILTER[0] = 1111H
2nd SPL coupling MD $MN_SAFE_SDP_FILTER[1] = 8888H
F net data signals from F_SENDDP:
MD $MN_SAFE_SDP_ID[0]
MD $MN_SAFE_SDP_LADDR[0]

SPL assignment
For the SPL assignment, the SPL outputs ($A_OUTSE) are selected, which are
assigned to the F net data signals via the F net data filter. Only a contiguous area
can be selected.
The SPL assignment is set using MD $MN_SAFE_SDP_ASSIGN[0...m].
The SPL output area data is specified in the decimal notation in the following
format:
$MN_SAFE_SDP_ASSIGN[n] = aaa bbb with
aaa: Area limit 1, SPL--SGA $A_OUTSE[aaa]
bbb: Area limit 2, SPL--SGA $A_OUTSE[bbb]
The following conditions should be observed when specifying the area limits:
S all area data is valid: (aaa > bbb), (aaa < bbb), (aaa = bbb)
S |(aaa -- bbb)| ≤ 16
In case of an error, Alarm 27301 "F_DP: MD %1[%2]: SPL coupling incorrect" is
output.
