Triggering Rules for Single Channel Devices

The VS-1 Smart Camera has a single acquisition channel. When a Job is constructed, only one Acquire can run at a time. Table 1-3 summarizes the recommended cases. Note that Visionscape® enforces this condition by honoring the first Acquire requested and generating an overrun on any other Acquire that are requested to run from the external controlling device (usually, an external trigger or a PLC).

TABLE 1-3. Triggering Rules

Job Structure	Snapshot Triggers	Behavior and Comments
1 Inspection/ Multiple Snapshots	1st triggered only or No triggers	Function without overruns, no further action from external controlling device.
1 Inspection/ Multiple Snapshots	All triggered	1st triggered externally, remaining self triggered from PicDone signal of previous Acquire.
N (max 4) inspections/ 1 Snapshot Each	All triggered/Each on a separate trigger	Works as expected in external controlling device makes sure that one Inspection is triggered at a time.
