24. March 2006 SLAC Workshop Control System Studio1 CSS Control System Studio Report on the current state Matthias Clausen DESY

24. March 2006 SLAC Workshop Control System Studio2 Today’s CSS Presentstion How CSS started What we wanted to do (slides from ICALEPCS presentation) What we have achieved Next steps

24. March 2006 SLAC Workshop Control System Studio3 Short History The Control System Studio initiative started in May 2005 during the EPICS workshop at SLAC –At this time it was still called ‘EPICS-Office’ –The basic ideas are still the same but the focus has been changed from EPICS centric to Control System openness. –During ICALEPCS’05 in Geneva the name changed from EPICS Office to Control System Studio. –The current developments are driven mainly by DESY Specifying fundamental interfaces (control system data API) Specifying and testing mandatory interfaces (naming/ logging…)

24. March 2006 SLAC Workshop Control System Studio4 What is the Control System Studio? It is (is going to be) an environment / framework which enables you to create your control system applications. It will provide interfaces to: –Control System Data –Control System Name Services –Control System Logging Services –Application Logging Services –Application Management Services –… more It will provide a generic infrastructure to built pluggable, component based applications: –High level applications (XAL) –User/ operator applications

24. March 2006 SLAC Workshop Control System Studio5 CSS (initial) Motivation The new EPICS Version will provide new features that must be supported also by the applications The existing applications (mainly written in X-Window) run (nearly) only on Unix machines. There are only a few programmers (left) that know how to program X-Window/ Motif The existing applications are similar to the first set of Microsoft applications. They do not share a common look and feel.

24. March 2006 SLAC Workshop Control System Studio6 Good reasons to think of a new application suite The new EPICS version 4.0 will provide several new features in the IOC and in Channel Access. These will only be available if the clients applications get modified/ rewritten accordingly. The ‚individual‘ look and feel of the existing applications should be changed to a -> Common look and feel Data exchange by objects and not only by name Compile once run ‚in most places‘ Common programming interfaces Application style guidelines Pluggable applications

24. March 2006 SLAC Workshop Control System Studio7 EPICS-V4 Status.. as of now(March 2006) Due to lack of manpower (and some ‘internals’) the current developments of EPICS-V4 have made only slow – but constant - progress over the last months. The design of the CSS-DataAccess API is contracted by DESY to Cosylab. –The ongoing work is coordinated with the V4 core team. This way we can make sure that the new API will be conformant with the current EPICS-V4 design Two contracts with industry to develop a Redundancy Monitor Task and for the Redundancy Continuous Control Executive are under way. First implementations – independent from Epics-V4 due in May’06

24. March 2006 SLAC Workshop Control System Studio16 CSS – Framework Writing Plugins The learning curve for Eclipse plugins is steep Developers which want to write CSS applications must be familiar with the Ecipse plugin ideas Help is needed to increase acceptance -> CSS plugin wizard –Write applications –Write Control System Interfaces –Write Graphic Plugins (widgets)

24. March 2006 SLAC Workshop Control System Studio22 Upgrade Plan How to upgrade from EPICS V3 to V4? What will happen with all the synoptic displays created on the EPICS sites? => Most of the displays are configured using the existing display tools. The configuration files can be converted into the new format and reused.

24. March 2006 SLAC Workshop Control System Studio23 Upgrade Procedure Generic Applications and Configuration- File Converters IOC Core and Database-File Converters EPICS-V3EPICS-V4 Converter DB pluggable CSO components pluggable records drivers (devices)

24. March 2006 SLAC Workshop Control System Studio24 Where are we now? In order to make the right/ reasonable decisions for the future we are not focusing on writing applications. Writing so called ‘Spikes’ we can test certain functionalities to find out what works, how – and why?

24. March 2006 SLAC Workshop Control System Studio25 Current CSS Status Internal Interfaces (I) CSS Drag and Drop Drag an object (with it’s data) from one CSS view (application) into another view (application). From the synoptic display (stripchart) into the data analysis tool. The proof of principle has been shown in a ‘spike’.
