Towards an industry 4.0 compliant control software architecture using IEC 61499 & OPC UA

The fourth industrial revolution introduced additional requirements on the industrial systems' control software in order to cope with current manufacturing systems' flexibility demands. These requirements include, among others, a dynamic reconfigurability, software reusability and an external service orchestration. This work presents the design of an industry 4.0 compliant control software architecture resulting from an iterative design process. The architecture is based on the reconfiguration services of the IEC 61499 standard and the service orchestration via OPC UA. We demonstrate the software architecture's compliance to the industry 4.0 requirements on an aluminum cold rolling mill plant demonstrator.
