IntroductionIntroduction

Prototype subsystem for controls• Evaluation - Vacuum Test Stand• Valve Control Crate• EPICS Database• Human-Computer Interface

18th June 2003

Vacuum Test Stand - ControllersVacuum Test Stand - Controllers

• MKS937A - Multi-sensor Vacuum Gauge System• Balzer TPG300 Vacuum Gauge Controller

• Varian Dual Ion Pump Controller• Digitel MPC Ion Pump Controller

• Mitsubishi ‘A’ Series PLC - Valve Control

• Also - Varian Titanium Sublimation Pump Controller (work in hand)

All devices use RS232 serial Interface

Vacuum Test Stand - IOCVacuum Test Stand - IOC

• VME 64X Crate

• MVME167 (M68K) or PPC604 (Power PC) processor card (work on 68k now discontinued)

• IP Carriers - Hytec VICB8002

- Greenspring VIPC601

• Serial Interface modules - Greenspring IPOctal

- Hytec 8515

Vacuum Test Stand - Serial DevicesVacuum Test Stand - Serial Devices

devAscii (Allan Honey, Jeff Hill - Keck)• We implemented MKS937A support.

StreamDevice (Dirk Zimoch, DELTA)• We implemented various support for various devices.

MPF (Marty Kraimer, APS)• Existing driver support for Digitel MPC Ion Pump Controller• We extended it to drive a Varian Dual Ion Pump Controller

ornlSerial (John Sinclair, Oak Ridge)• We implemented a plug-in for MKS937A• Also extended record support to cover standard EPICS ai and ao modules

Conclusions• All devices work with no more than minor problems• Where existing support exists we will use it

For new development• use StreamDevice for straightforward cases• use ornlSerial for complex protocols / checksums

Vacuum Valve Control CrateVacuum Valve Control Crate

Object - all other vacuum equipment handled by a gauge or pump controller

• Maintains control across restart of IOC• Need same facility for valves, absorbers

Use a PLC

Provides interlocks• Pressures• Water flow switches

Current preference - Allen Bradley Compact Logix • Allen Bradley serial interface• DF1 Protocol (Alan Honey)

EPICS DatabaseEPICS Database

Equipment choice - not finalised• For test database assume• MKS937A Vacuum Gauge Controller• Digitel MPC Ion Pump Controller• Allen Bradley Compact Logix PLC - Valve Control• Varian TSP controller

EPICS DatabaseEPICS Database

Set up substitution files

Template files already exist from test stand

Expand database on host, download expanded files• Use expanded files to populate relational database.

Work clarified our ideas on project directory structure.

Alternative set of template files - provide soft records and simulation

Vacuum HCIVacuum HCI

Use EDM to build screens

- Find limitations

- Need to add records in database - calculations, waveform records for plot etc.

• (not a problem for vacuum system but may be for more complicated systems)

Plans to try other approaches

- Java, Abeans

- Scripting languages

- etc.
