DBX3.1
Edge evaluation:
Signal state 1 or This signal enables the triggering of a single stroke in manual mode.
edge change 0 → 1
1 signal: Manual stroke is performed.
Signal state 0 or 0 signal: No effect.
edge change 1 → 0
DB21, ...
DBX3.2
Edge evaluation:
Signal state 1 or This signal simply prevents execution of the stroke. The machine traverses anyway.
edge change 0 → 1 The automatic path segmentation remains active if it is already activated.
Only the signal "Stroke initiation" is suppressed.
The machine traverses in "stop and go" mode.
The step length is defined via the path segmentation.
1 signal: Stroke suppression is active.
Signal state 0 or 0 signal: Stroke suppression is not active.
edge change 1 → 0

DBX3.3
Edge evaluation:
Signal state 1 or A "Delayed stroke" can be activated via this signal. This corresponds in function to the
edge change 0 → 1 programming of PDELAYON. Other PLC signals not corresponding to the standard are not evaluated
in the NCK. With the exception of the manual stroke initiation, the evaluation of signals is limited to
PON active.
1 signal: Delayed stroke is active.
Signal state 0 or 0 signal: Delayed stroke is not active.
edge change 1 → 0
