Matthias Clausen, DESY CSS GSI Feb. 2009: Introduction XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 8 ITER Statement The CODAC group initiated a number of actions in the first half of 2008 in order to select a software environment as a part of moving from the conceptual design to an engineering design of CODAC. The conclusion of all these activities is that ITER, being an experimental facility with a very long timeline, is better suited using an open source solution as compared to a commercial solution. Further, the reports conclude that technically, any of the candidate open-source solutions would work. However, due to market share and proven record the preferred solution would be EPICS. As a consequence, the CODAC group announces that EPICS will be used as the baseline for the software environment for the ITER control system within the scope of PCDH (Plant Control Design Handbook).

Matthias Clausen, DESY CSS GSI Feb. 2009: Introduction XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 11 Advantages of the ‘EPICS – Way’ Code running on the IOC is very stable –EPICS core software developed by core team (specialists) –Core is tested on all main operating systems before any new release. –Only specialists create new drivers –Core and drivers are running in many installations worldwide Code is well tested and debugged Process engineers configure databases –No code created –IOC’s only differ by databases – the stable code remains the same –Database configuration tools can be used by remote consulting/ engineering companies to create EPICS databases. (Database text files can be send via to DESY)

Matthias Clausen, DESY CSS GSI Feb. 2009: Introduction XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 12 EPICS at DESY EPICS is in operation at DESY since more than 18 years. From the very beginning it is used for cryogenic controls. – Which is process controls. Only a few years later (1993) EPICS was also introduced for the distributed PLCs of the utility controls group. Since then all of the cryogenic plants at DESY are – or will be (2009) controlled by EPICS IOCs All of the utility controls are and will be using EPICS to supervise their extended PLC infrastructure for monitoring and controls. – Like a SCADA system This applies also for the new projects: PETRA-III and the European XFEL

Matthias Clausen, DESY CSS GSI Feb. 2009: Introduction XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 13 EPICS for Cryogenic Controls EPICS fulfills all the requirements of cryogenic control Process control System –Control Loops on IOC –Sequencer on IOC Process Control Applications –Synoptic Display –Archiver / Viewer –Alarm-System / Alarm Display – …
