2 What EPICS-Office is is NOT It is NOT YADM Yet Another Display Manager It is NOT YADCT Yet Another Database Creation Tool It is NOT an Application on it s own EPICS Office 2

3 What is EPICS-Office? It is an environment / framework which enables you to create your control system applications. It shall provide interfaces to: Control System Data Control System Name Services Control System Logging Services Application Logging Services Application Management Services more It shall provide a generic infrastructure to built pluggable, component based applications: High level applications (XAL) User/ operator applications EPICS Office 3

5 CSO-Office 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. Control System Office 5

6 EPICS 4.0 Goals Provide online add/disable of I/O to support continuous operation. Provide redundant control of remote I/O to support improved reliability. Provide name introspection and domain control in support of seamless integration of large control systems Provide triggers, filters, and rate limits to improve resource use of network and client side processing Provide atomic read/write of multiple fields in a record Remove limitations on string lengths, device states, number of input links to support arbitrary sizes/dimension arrays. Record Library to provide pluggable functionality Provide hierarchical devices/ device functionality to support higher level view of application in the front-end processors. Alternate protocols Write with read-back Provide better channel access diagnostics Control System Office 6

7 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 Control System Office 7

16 CSO Framework Writing Plugins The learning curve for Eclipse plugins is steep Developers which want to write CSO applications must be familiar with the Ecipse plugin ideas Help is needed to increase acceptance -> CSO plugin wizard Write applications Write Control System Interfaces Write Graphic Plugins (widgets) Control System Office 16

18 Eclipse Acceptance Widely accepted by industry Last companies to join the Eclipse foundation: Nokia, Compuware Accepted in the EPICS community Accepted at DESY Available through Netinstall at DESY Common interest with TANGO developers and others Eclipse workshop held before ICALEPCS started successfully with 28 participants Control System Office 18

22 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. Control System Office 22

23 Upgrade Procedure Generic Applications and Configuration- File Converters EPICS-V3 Converter EPICS-V4 pluggable CSO components IOC Core and Database-File Converters DB DB pluggable records drivers (devices) Control System Office 23

32 Next Steps Finish Control System Data Access API by Christmas this year. (We might also have a look at JAPC from CERN) Finish specification of remaining interfaces in first quarter 2006 First straw man applications middle of 2006 Beta release of EPICS V4 and Control System Office applications by the end of 2006 Control System Office 32

33 Conclusions The EPICS collaboration is taking a major step forward by developing a new major EPICS release. The aim to be ready by end of 2006 also with a new Controls System Office Framework is getting momentum and will most likely be ready in parallel with the new core release. Collecting use cases and requirements is a challenging task, but is necessary for a solid foundation for this new framework. Control System Office 33
