2.9.2 Activation of skip levels
/, /0, ... /9
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 "/7".
Only one skip level can be specified for each part program block.
Number of levels
The number of skip levels is defined with MD9423 $MM_MAX_SKP_LEVEL (max. skip levels
in the NC program).
Example signals:
Blocks which are not to be executed in every program pass can be skipped according to the
following diagram (e.g., program test blocks):/ ; block skipped, (DB21, ... DBX2.0) 1st skip
level
/ N005 ; block skipped, (DB21, ... DBX2.0) 1. "
/0 N005 ; block skipped, (DB21, ... DBX2.0) 1. "
/1 N010 ; block skipped, (DB21, ... DBX2.1) 2. "
/2 N020 ; block skipped, (DB21, ... DBX2.2) 3. "
/3 N030 ; block skipped, (DB21, ... DBX2.3) 4. "
/4 N040 ; block skipped, (DB21, ... DBX2.4) 5. "
/5 N050 ; block skipped, (DB21, ... DBX2.5) 6. "
/6 N060 ; block skipped, (DB21, ... DBX2.6), 7. "
/7 N070 ; block skipped, (DB21, ... DBX2.7) 8. skip level
/8 N080 ; block skipped, (DB21, ... DBX31.6), 9. skip level
/9 N090 ; block skipped, (DB21, ... DBX31.7) 10. skip level
The 10 skip levels "/0" to "/9" are activated by the PLC setting the PLC -> NCK interface
signals.
The function is activated from the HMI via the "Program control" menu in the Machine
operating area for skip levels
• "/0" to "/7" via interface HMI -> PLC DB21, ... DBB26 (Skipped block selected).
• "/8" to "/9" via interface HMI -> PLC DB21, ... DBX27.0 to DBX27.1.

Note
The levels to be skipped can only be changed when the control is in the STOP/RESET state.
