Assignment: F useful data is assigned to the SPL SGE/SGAs using the NCK machine data:
F useful data to
•
SPL SGE/SGA
•
Index: 0...15
Input format: eee sss
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:
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:
refer to the F module whose PROFIsafe address is entered under the same
index in NCK machine data:
