In TMC the reference TriggersRejection was available. "The OPC UA Reference Type TriggersRejection is used to identify the causal link between product defect sensing and product rejection. More specifically, the OPC UA Reference Type TiggersRejection connects an OPC UA object of type DefectDetectionSensorType to an OPC UA object of type MaterialRejectionTrapType that is triggered by the defect sensor.
The InverseName is TriggeredByDetection." In OPC 30060 v2.00.1 there is no way to identify this link. The requirement is to identify which is the reason of a reject and possibly totals the rejections by reason.
