D.4.2.1 Problem Statement

Imagine a plant with an automated assembly line, which is directed by an MES (Manufacturing Execution System) and operated by line/cell controllers (PLCs). The joining system is controlled by a PLC.

The MES directs the joining process of individual joints via PLCs, but the handling of results.

is limited via traditional communication channels, like fieldbus networks.

relies on propriety data channels that require different implementations depending on the manufacturer.

This use case can be applicable for the following communication setup:

Joining system with OPC UA and fieldbus interfaces.

Joining system with only OPC UA.
