DB21, ...
DBX1.7 Activate program test
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
Activation of the program test is requested.
During the program test, all motion commands of axes (not spindles) take place under "Axis
disable."
Notice!
Due to the axis disable, the assignment of a tool magazine is not changed for the program test. The
user/machine manufacturer must utilize a suitable PLC user program to ensure that the NCK-
internal tool management and the actual assignment of the tool magazine remain consistent. Refer
to the program example included in the PLC Toolbox.
Signal state 0 or
edge change
1 → 0
Activation of the program test is not requested.

DBB2 Activate skip block
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
Skip blocks marked in the part program with an slash (/) are not processed. If there is a series of skip
blocks, the signal is only active if it is present before the first skip block of the series is decoded.
Note
The signal should be available prior to the start of the part program.
Signal state 0 or
edge change
1 → 0
Skip blocks marked in the part program with an slash (/) are processed.
Corresponding to ... DB21, ... DBX26.0 (Skip block selected)
DB21, ... DBX35.2 (Program status stopped)
DB21, ...
DBX6.1 Read-in disable
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The main run reads in no more preprocessed part program blocks.
Note
The signal is only active in AUTOMATIC and MDA modes.
Signal state 0 or
edge change
1 → 0
The main run reads in preprocessed part program blocks.
Corresponding to ... DB21, ... DBX35.0 (program status running)

DBX6.4 Program level abort
Edge evaluation: yes Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
At each edge change 0 → 1 the current program level being processed (subroutine level, ASUB
level, save routine) is immediately aborted. Processing of the part program continues at the next
higher program level from the exit point.
