Program code

Blocks can be assigned to skip levels (max. 10), which can be activated via the user interface

or the PLC user program.

The assignment is made in the NC program using a forward slash, followed by the number of

the skip level. Only one skip level can be specified for each block.

Program code

The levels to be skipped can only be changed when the control system is in the STOP/reset

The number of skip levels that can be used depends on a display machine data.

Skipping blocks also remains active during block searches.

System and user variables can also be used in conditional jumps in order to control program
