The Detector Control System (DCS) of the ATLAS experiment at the LHC has been using the OPC DA standard as interface for controlling various standard and custom hardware components and their integration into the SCADA layer. Due to its platform restrictions and expiring long-term support, OPC DA will be replaced by the succeeding OPC Unified Architecture (UA) standard. OPC UA offers powerful object-oriented information modeling capabilities, platform independence, secure communication and allows server embedding into custom electronics. We present an OPC UA server implementation for CANopen devices which is used in the ATLAS DCS to control dedicated IO boards distributed within and outside the detector. Architecture and server configuration aspects are detailed and the server performance is evaluated and compared with the previous OPC DA server. Furthermore, based on the experience with the first server implementation, OPC UA is evaluated as standard middleware solution for future use in the ATLAS DCS and beyond.
