D.4.2.3 Workflow

The MES controls the flow of parts via

OPC UA

PLCs and their fieldbus interfaces (if available)

The MES/PLC sends the product/part identification (e.g. VIN), joining program and start signal via

OPC UA

Fieldbus

The joining system performs the joining operation.

The MES systems receive the (extensive) joining result via OPC UA, including the joint identification.
