Integration of OPC UA at ELBE

Zenker, K.; Steinbr├╝ck, R.; Kuntzsch, M.

The Electron Linac for beams with high Brilliance and low Emittance (ELBE) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is in operation since 2001. It is operated using the SCADA system WinCC by Siemens. The majority of ELBE systems is connected to WinCC via industrial Ethernet and proprietary S7 communication. However, in recent years new subsystems had to be integrated into the existing infrastructure, which do not provide S7 communication interfaces. Instead, OPC UA has been chosen for system integration. We will show how we use OPC UA as a common communication layer between industrial and scientific instruments as well as proprietary and open source control system software. For example, OPC UA support has been implemented for the ChimeraTK framework developed at DESY. ChimeraTK is used at ELBE e.g. for integrating MicroTCA.4 based subsystems like the digital LLRF system. Furthermore, we are developing a machine data interface for ELBE users. In combination with a certification authority, which hands out user certificates for data access, external users can gain read and write access to different ELBE subsystem data provided by a single OPC UA server.
