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
The Global_IN network
must be modified if more than nine axes are selected. If other keys and LEDs are to be used
on the machine control panel here, proceed as follows:
1. The command UD DW#16#Value (comment: Clear all axis LEDs for display) deletes all
2. The command UW W#16# (comment: "Masking all the axis selection buttons" ) checks
3. 3. The branch destination list (SPL) must be expanded with new jump labels. The new
The blocks are made available as STL sources if required. But they do not match the current
status of the block. Some details of the actual implementation in C have been developed
further. For this reason we recommend that you specify your additional requirements for the
blocks and that you pass these onto project management via the sales department.

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.
