1. 14-Nov-2000EPICS Workshop - Oak Ridge1 PCaPAC Review Matthias Clausen DESY/ MKS-2

2. 14-Nov-2000EPICS Workshop - Oak Ridge2 PCaPAC 2000 PCaPAC : Personal Computers and Particle Accelerator Controls The third international workshop held in between ICALEPCS conferences. PCaPAC is not in competition with ICALEPCS but meant to be a complement to ICALEPCS. Held from October 9-12 2000 @ DESY About 120 participants

3. 14-Nov-2000EPICS Workshop - Oak Ridge3 Topics :  Controlling Accelerator Subsystems and Experiments  running systems: including commercial or SCADA systems  Operator Interface  Interfacing Accelerator Hardware  Accelerator Control Objects and Components  Integrating Different Systems  Control System Architecture  System Administration and Project Management  Future Trends and Technologies

4. 14-Nov-2000EPICS Workshop - Oak Ridge4 Control System Architecture (I)  COACK Component Oriented Accelerator Control Kernel Development driven by Isamu Abe from KEK Implementation by industry. License free for other HEP institutes  Central Windows NT Server running MS-SQL  Basic functions: Graphics, Logs, Alarms… available. Implemented using MS programs  All data written and read to/from database  Interface for external devices: XML  Limited to some thousand I/O points

5. 14-Nov-2000EPICS Workshop - Oak Ridge5 Control System Architecture (II)  TINE Backbone protocol for DESY accelerator controls Publish / subscribe communication Applications on workstation written in V-Basic Applications on front end written in ‘C’ C++ or V-Basic Variety of operating systems supported  TANGO CORBA based control system @ ESRF Genoble Interface to ‘old’ control system TACO (RPC based) Full Linux support

6. 14-Nov-2000EPICS Workshop - Oak Ridge6 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 of Java Beans can be copied ‘as is’

7. 14-Nov-2000EPICS Workshop - Oak Ridge7 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  Office PC’s as well as Linux farms  SUSE YaST-2 management tool  AFS support  Boot from a floppy

8. 14-Nov-2000EPICS Workshop - Oak Ridge8 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

9. 14-Nov-2000EPICS Workshop - Oak Ridge9 Tutorials :  Java / Corba in a Nutshell (by Mark Plesko)  Networking Technology Trends (CISCO)  Higher bandwidth beyond 1Gbit (still Ethernet)  Distribution of ‘Hot Spot’ data files:  Remote learning  Remote Video  IPV6 delayed (if ever)  ? Quality of service  ? Address space  SCADA …
