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 …

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).

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 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)

New Developments: Operator Interface
Motivation – 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)

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

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’
