9.13.2 Activation of skip levels
Function
It is possible to skip blocks, which are not to be executed every time the program runs. Blocks to be skipped are
indicated in the part program by an oblique "/" before the block number.
The skip levels in the parts program are specified by "/0" to "/9".
Only one skip level can be specified for each part program block.
Parameter assignment
The number of skip levels is defined using machine data:
MD51029 $MM_MAX_SKP_LEVEL (max. number of skip levels in the NC program)
Programming
Blocks, which are not to be executed in every program pass (e.g., program test blocks) can be skipped according
to the following schematic.
DRF selection DB21, ... DBX24.3 DB21, ... DBX0.3 DB21, ... DBX33.3
PRT program test DB21, ... DBX25.7 DB21, ... DBX1.7 DB21, ... DBX33.7
