TI - Integrating OPC UA Devices in EPICS J2 - Proc. of ICALEPCS2021, Shanghai, China, 14-22 October 2021 CY - Shanghai, China T2 - International Conference on Accelerator and Large Experimental Physics Control Systems T3 - 18 LA - english AB - OPC Unified Architecture (OPC UA) is an open platform independent communication architecture for industrial automation developed by the OPC Foundation. Its key characteristics include a rich service-oriented architecture, enhanced security functionality and an integral information model, allowing to map complex data into an OPC UA namespace. With its increasing popularity in the industrial world, OPC UA is an excellent strategic choice for integrating a wealth of different COTS devices and controllers into an existing control system infrastructure. The security functions extend its application to larger networks and across firewalls, while the support of user-defined data structures and fully symbolic addressing ensure flexibility, separation of concerns and robustness in the user interfaces. In an international collaboration, a generic OPC UA support for the EPICS control system toolkit has been developed. It is used in operation at several facilities, integrating a variety of commercial controllers and systems. We describe design and implementation approach, discuss use cases and software quality aspects, report performance and present a roadmap of the next development steps.
