F useful data is assigned to the SPL SGE/SGAs using the NCK machine data:
•
MD 10388: $MN_PROFISAFE_IN_ASSIGN[Index],
(assignment between ext. SPL-SST $A_INSE/INSEP and PROFIsafe input
modules)
•
MD 10389: $MN_PROFISAFE_OUT_ASSIGN[Index],
(assignment between ext. SPL-SST $A_OUTSE/OUTSEP and PROFIsafe
output modules)
Index: 0...15
Input format: eee sss
-
sss: decimal SGE/SGA start address (1...64)
-
eee: decimal SGE/SGA end address (1...64)
The SGE/SGA
start address
always assigns
bit 0
of the F useful data to the
SPL SGE/SGA[
sss
].
The SGE/SGA
end address
always assigns
bit n
of the F useful data to the
SPL SGE/SGA[
eee
]. Bit number n is calculated as follows:
n = eee - sss
The bits of the F useful data, that lie between bit 0 and bit n are automatically
assigned by the NCK to the SGEs/SGAs that lie between the SGE/SGA
start
address
and the
end address
.
The assignment of the F module for supplying/clearing the input/output data for
the SPL SGE/SGAs is made implicitly via the machine data index; i.e. the
input/output data assigned to the SPL/SGEs/SGAs per NCK machine data:
-
...PROFISAFE_IN/OUT_
ASSIGN
[
Index

refer to the F module whose PROFIsafe address is entered under the same
index in NCK machine data:

Note
The NCK machine data:
•
MD 10386: $MN_PROFISAFE_IN_ADDRESS[Index]
•
MD 10388: $MN_PROFISAFE_IN_ASSIGN[Index]

•
MD 10387: $MN_PROFISAFE_OUT_ADDRESS[Index]
