Control and Monitoring System / EPICS

CM19 8-10-07 Pete Owens – Daresbury Laboratory

General Philosophy

• Control system is based on EPICS.• In general, individual groups are to be responsible

for interfacing their own equipment to EPICS• DL will provide overall infrastructure and support• In agreed cases, DL will take responsibility for

developing individual EPICS applications eg. Beamline PSUs, Decay Solenoid PSU etc.

• Naming convention• Long-term support. Who will take on operational

responsibility for day-to-day management of systems?

Personnel Safety

• PPS hardware and logic has been designed , procured and the racks built and tested.

• An EPICS interface will be provided for remote monitoring of operation.

• XML gateway to be added to feed information back to the ISIS control system.

• Still some issues remaining about the hall search philosophy, siting of search buttons etc.

Beamline PSUs

• Racks built up – imminent delivery to RAL

• 12 Danfysik System 9000 PSUs• RS422 serial comms to IOC• EPICS database• EDM user interface

Decay Solenoid PSU

• The power supply has been tested at DL• Control electronics have been reverse engineered• PLC system was old, complex and difficult to

support so has been abandoned in favour of an EPICS IOC

• Quench detection and heater control electronics have been refurbished and tested

• New control software scheme has been agreed• IOC being built up.

Hydrogen System

• Meetings have been held to discuss control requirements for the H2 system

• Little progress possible until the decay solenoid system is complete.

Target

• Sheffield group responsible for providing the control interface to the target drive system

• DL will provide training, advice if necessary

CM19 8-10-07 Pete Owens – Daresbury Laboratory

Tracker

• Imperial to develop their own EPICS software to control the tracker.

• DL will provide training, advice if necessary

RF System

• Design review planned to be held at DL in the next couple of months.

• This will include control requirements
