EPICS Collaboration Meeting Argonne June 2006 EPICS Eclipse is an Open Source community It was started in 2001 by IBM ● IBM donated a lot of research ● Controlled the early development, but later relinquished control Out of the box it looks like a Java IDE It is really a Plug-in manager ● That happens to come with Java Development plug-ins. ● You can take these out and put your own (and/or others) in © Kenneth Evans, Jr. Matthias Clausen, DESY CSS Overview, 13 -June-06 5

EPICS Collaboration Meeting Argonne June 2006 EPICS Archive Viewer (Sergei Chevtsov) Emphasizing the MVC approach Having implemented the initial version following the MVC paradigm, the conversion into an Eclipse RCP application is ‘much’ easier. The archive viewer can become one of the core CSS applications. It can also be used as a strip tool 17 Matthias Clausen, DESY CSS Overview, 13 -June-06

EPICS Collaboration Meeting Argonne June 2006 EPICS What is the Control System Studio (CSS)? It is an environment / framework which enables you to create your control system applications. (It’s not an CS-applications on its own) It shall offer a common look and feel for all applications Run on any ‘standard’ operation system It shall provide an infrastructure/ interfaces for the basic CS environment ● ● Control System Data Utility Interfaces (logging…) Management Interfaces (authorization, authentication, update, …) Common Application activation interfaces Must be ready for the next projects at DESY: ● PETRA-III (2008) ● XFEL-Cryogenics (2008/ 9) CSS Core prototype in autumn 2006 CSS Application prototypes by the end of the year 19 EPICS Office

EPICS Collaboration Meeting Argonne June 2006 EPICS Collaboration/ Contracts with Companies We do not have the necessary manpower and not the necessary experience to develop such a framework all on our own.
