Control System Architecture (III)
 ANKA Control
System (Mark Plesco)
Based on Java
Working reliably well
Example for remote development of software
 Development
is specific to the controls problem
 Mainly the implementation ideas can be copied for
future projects
 A lot

System Administration
 NT Administration



Special application (here: NetInstall) necessary to coordinate the installation
of NT products
Trigger regular updates
Distinguish between office and controls PC’s
 Linux Administration





Trends
 Future
Web technologies (Alberto Pace / CERN)
Using the Web not only for Web-pages but also http for file transfer
(No AFS needed any more)
 XML


As a new standard document type
As a basis for data exchange
EPICS as a trend setter
How does the collaboration work
 How does software distribution work
-> promote collaboration instead of functionality
