Begin the proposed design with one representative station. Assign a workpiece identifier at the trigger. Generate a decision from the acquired image and matching inspection recipe. Send the identifier and decision to the controller. Agree on a response deadline and acknowledgment method. The site interface and machine cycle remain pending verification.
Define normal and exception handling
Define what to do for pass, fail, pending review and no valid result. Each acknowledgment must match the workpiece and decision. Follow the agreed process for timeouts, duplicate results or identifier mismatches, and record the reason. If evidence images are generated separately, verify completion of both the control result and the evidence image.
Test the interface with representative workpieces
Check consecutive arrivals, recipe changes, missing images, communication recovery and late results. Retain trigger, decision, controller acknowledgment and station completion records. Check deadlines, mismatches, timeouts and cycle time under the actual concurrent workload. Production acceptance requires the agreed samples and site records.
During integration, record what the controller does with a late result. Check whether it still maps to the original workpiece and whether that workpiece has left the station. Retest while new workpieces continue to arrive normally.
