The output parameters are prepared and the LED signals of the INC machine function are
generated in the global_out network.
The output network transfers the output signals of the machine control panel from the
VAR_TEMP image to the logical address. The data for the next cycle are also saved.
Axis selection extension
Network Global_in must be modified for more than 9 axes. If other keys and LEDs are to be
used on the machine control panel here, proceed as follows:
1. The UD DW#16#Wert command deletes all LEDs defined for axis selections.
The bit mask is currently processing the 9 axis selection LED.
2. The UW W#16# command, with the comment "Mask all axis selection keys" checks for a
new selection of direction. The bit string must be adjusted here.
3. The branch destination list (SPL) must be expanded with new jump labels.
The new jump labels should be inserted in descending order before label m009. The
selection information should be extended for the new jump labels, as described for labels
m009 and m008.
