The ATLAS experiment is one of the multi-purpose experiments at the Large Hadron Collider (LHC), constructed to study elementary particle interactions in collisions of high-energy proton beams. Twelve different sub-detectors as well as the common experimental infrastructure are supervised by the Detector Control System (DCS). The DCS enables equipment supervision of all ATLAS sub-detectors by using a system of 140 server machines running the industrial SCADA product PVSS. This highly distributed system reads, processes and archives of the order of 10⁶ operational parameters. Higher level control system layers based on the CERN JCOP framework allow for automatic control procedures, efficient error recognition and handling, manage the communication with external control systems such as the LHC controls, and provide a synchronization mechanism with the ATLAS physics data acquisition system. A web-based monitoring system allows accessing the DCS operator interface views and browse the conditions data archive worldwide with high availability. This contribution firstly describes the status of the ATLAS DCS and the experience gained during the LHC commissioning and the first physics data taking operation period. Secondly, the future evolution and maintenance constraints for the coming years and the LHC high luminosity upgrades are outlined.

The ATLAS experiment at CERN is one of the four Large Hadron Collider ex- periments. ATLAS uses a commercial SCADA system (PVSS) for its Detector Control System (DCS) which is responsible for the supervision of the detector equipment, the reading of operational parameters, the propagation of the alarms and the archiving of important operational data in a relational database. DCS Data Viewer (DDV) is an application that provides access to historical data of DCS parameters written to the database through a web interface. It has a modular and flexible design and is structured using a client-server architecture. The server can be operated stand alone with a command-like interface to the data while the client offers a user friendly, browser independent interface. The selection of the metadata of DCS parameters is done via a column-tree view or with a powerful search engine. The final visualisation of the data is done using various plugins such as "value over time" charts, data tables, raw ASCII or structured export to ROOT. Excessive access or malicious use of the database is prevented by dedicated protection mechanisms, allowing the exposure of the tool to hundreds of inexperienced users. The metadata selection and data output features can be used separately by XML configuration files. Security constraints have been taken into account in the implementation allowing the access of DDV by collaborators worldwide. Due to its flexible interface and its generic and modular approach, DDV could be easily used for other experiment control systems that archive data using PVSS.
