Control System Studio– History– Requirements



A brief Introduction to EPICS

What is EPICS?

EPICS = Experimental Physics and Industrial Control System

• The Collaboration• Basic Concept

– Input Output Controller (IOC)– Network Protocol (Channel Access - CA)– Application



EPICS Collaboration

< 2003: 150 EPICS user Licenses

> 2003: open source



EPICS Collaboration:It’s the people

Collaboration Meeting Archamps 2005103 Participants 34 Institutes 4 Companies



Breaking News:

The EPICS Collaboration will grow even further

As of February 1st ITER announced that EPICS will be used as the baseline for the software environment for the ITER control system …

(Published via EPICS TechTalk on Feb. 10th)



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).

EPICS – The Basic Concept

IOC

I/O-Local, or-On a field bus

CA ( Channel Access)- ip-based communication protocol

IOC-Control loops-Sequence programs

Control Loops-Permanently running at sprecise scan time

IOC OperationIs independent fromNetwork Connection

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 email to DESY)



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



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– …



EPICS for Utility Controls

The utility controls group is using EPICS as a SCADA system• Configuring EPICS databases• Configuring display files• Configuring alarm configuration files• Configuring archive configuration files

The utility controls group can use EPICS ‘independent’ from the cryogenic controls group, which is providing the ‘service’ to prepare:

• EPICS applications• EPICS-IOC core software (including drivers)

Looking back in History



New Developments: Operator InterfaceMotivation – Current State

Have a look at current operator interfaces:• Many applications of different kind

– Implemented by different programmers

– Different look and feel

– Implemented in different programming languages

– GUI with text in specific languages ( difficulties for Japanese Operators)

– Running only on specific operating systems

– Running only in the context of a specific control system type

• Which kind of data/ information transfer are possible?– Drag and drop basic information as ‘string’

– Cut and paste ‘strings’

– Drag and drop ‘objects’ within the same program environment (Windows)



History

• 2005– EPICS Office

An Initiative for a newControl System Office Framework



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



History



• 2006– CSO Control System Office



CSO Interfaces

Control System– Data Access– Name Services– Logging Services– Archive Data

Utility– Application Logging Services– Application Management Services

• Trigger Updates, Monitor running CSO Instances, Stop CSO Instance– Record/ Playback– Relational Database

Graphic– Graphic Service– Widgets

Application/ Application– Drag/ Drop



History



• 2006– CSO Control System Office– Adding the Idea of Interfaces to the Control System(s)

• 2006– CSS Control System Studio– Brain Storming Workshop @ DESY– Focus: ‘Information on your fingertip’– Decision to use Eclipse– Decision to implement CSS-Core by specialists from

University (C1-WPS)



New Developments: Control System StudioCSS Design

Design Criteria:– Common Look and Feel– ‘Information on your Fingertips’

Find related applications using <MB3>– Drag and drop Java objects between (CSS compliant)

applications– Management of installed CSS installations– Talking to control systems through interfaces rather than directly

through control system specific API’s– Authentication/ Authorization– Internationalization– Do not preclude other implementations

• Integration by ‘plugin’
