EPICSProposed Beamline Layout



EPICSControl System Architecture

• Based on EPICS using Two Layer Model

Primary interface to CS through VME IOCsUse VME64x, IP carriers, IP Modules and transition board for rear

connection Hot Swap capability

• Will use PLCs to manage interlocks for protection

Avoids Watch Dogs on IOCs and allow warm reboot of IOCs AB Control Logix PLCs for low end applications, eg Vac Valve controlSiemens S7/300 and S7/400 for high end applications, eg Linac and

Cryoplant

• Serial Interface to Instrumentation

Potentially several thousandSerial support through Stream Device and ORNL Serial



EPICSHardware

• Development

Linux for DevelopmentRunning EPICS 3.13.4 will move to 3.14.x

• Consoles

PCs running Linux Will support Win2000

• IOCs

VME64x PPC Processor boards

Select processor Autumn 2003Will use IP carrier and modulesPrimarily 7 slot crates



EPICSRecent Developments

• Standardised on SLS PSU controller for 1300 PSUs

Full digital regulationCS Interface through high speed point to point link

• Development of APS/SLS Event System with SLS and Micro Research

Move to 2.5Gbit transmission, reduce jitter, enable distribution of RF clock and recovery using VCO

• Development of Application Development Environment

Define processes and sequences of building applicationsLocal development on Linux PCs, CVS for revision control and

server for final check out to operationsNeed to integrate upload to RDB seamlessly
