  9. DESY Control Groups • The two accelerator control groups joined together • Goal: benefit from the complementary strength of DOOCS and TINE

  10. ICALEPCS 2007 XFEL Developments • GUI software based on JAVA • 3 projects • Evaluation of a new crate standard: ATCA / µTCA • Modern GigaLink communication (no bus) • Redundant design (up to 99.999% availability) • Management infrastructure is part of the specification • IPMI on board and crate level • DOOCS server development • Management server and display • Redundant device server or subsystem operation

  11. ICALEPCS 2007 The Applications: jddd jddd: data presentation, controls and analysis framework to create complex operation panels without programming

  12. ICALEPCS 2007 Data Browser Tree shows all online variables of the control system Drag&Drop to add a column (property) to the SpreadSheet jDTool: Tool to display and modify all control system variables

  13. ICALEPCS 2007 Alarm Display Ticker of all alarms Ticker of one device or group Hierarchical view of all devices
