DB21, ...
DBX35.5
Channel status active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
In this channel:
• A part program is presently being executed in Automatic or MDA mode
or
• At least one axis is being traversed in JOG mode.
Signal state 0 or
edge change
1 → 0
DB21, ... DBX35.3 (Channel status interrupted) or DB21, ... DB35.7 (Channel status reset) is
available.
DB21, ...
DBX35.6
Channel status interrupted
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The NC part program in AUTOMATIC or MDA mode or a traversing motion in JOG mode can be
interrupted by:
• DB21, ... DBX7.3 (NC stop)
• DB21, ... DBX7.4 (NC stop, axes plus spindles)
• DB21, ... DBX7.2 (NC stop at the block limit)
• Programmed M00 or M01
Or
• Single block mode
After an NC start the part program or the interrupted traversing movement can be continued.
Signal state 0 or
edge change
1 → 0
DB21, ... DBX35.3 (Channel status active) or DB21, ... DB35.7 (Channel status reset) is available.
DB21, ...
DBX35.7
Channel status reset
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The signal changes to 1 as soon as the channel goes into the reset state, i.e. no processing taking
place.
Signal state 0 or
edge change
1 → 0
The signal is set to 0 as soon as processing takes place in the channel, e.g.:
• Execution of a part program
• Block search
• TEACH IN active
• Overstore active
