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.
Signal state 0 or
edge change
1 → 0
No effect.
Special cases,
errors, ......
The main program level cannot be aborted with this IS, only with IS "Reset".
DB21, ...
DBX7.0
NC START disable
Edge evaluation: no
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The NC START disable prevents a part program from being started with NC START signal DB21, ...
DBX7.1 (NC START) == 1.
Signal state 0 or
edge change
1 → 0
NC START disable is not active.
Special cases,
errors, ......
The start of a part program selected in the channel by part program command
START
in another
channel (program coordination) is not prevented by the interface signal:
DB21, ... DBX7.0 (NC start disable) == 1.
Corresponds to ....
DB21, ... DBX7.1 (NC START)
DB21, ...
DBX7.1
NC START
Edge evaluation: yes
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
AUTOMATIC mode: The selected NC program is started or continued, or the auxiliary functions that
were saved during the program interruption are output.
If data are transferred from the PLC to the NC during program status "Program interrupted," then
these data are immediately cleared at NC start.
Operating mode MDA:
The entered block information or part program blocks are released for execution.
Signal state 0 or
edge change
1 → 0
No effect.
Corresponds to ....
DB21, ... DBX7.0 (NC start disable)
