AcquisitionDoneEventType is an EventType subtype of BaseEventType, defined in OPC 10000-5. This event is to be triggered by the server. when the vision system finishes a data acquisition process for a job. Figure 31 shows the structure of the event. It is formally defined in Table 113.

It is not shown explicitly in the state machine diagram as it is not directly connected to a transition.

It indicates to the client that data acquisition for the specified job has finished. In many machines, this will be a signal that the work piece or camera can be moved. Triggering this event during a single or continuous execution is application-specific and not mandatory.

The event provides the JobId created upon the transition from the Ready state to the SingleExecution or ContinuousExecution state. This enables the client to maintain a time-sequential log of state changes for each job and also to match the event to the corresponding start signal.

In the case of multiple running state machines in the same server, the client can use the Source property inherited from BaseEventType to identify the state machine instance the event originated from.

JobId

The Id of the job for which the event was triggered. The JobId is created by the transition from state Ready to state Acquiring.
