Introduction Prototype subsystem for controls Evaluation - Vacuum Test Stand Valve Control Crate EPICS Database Human-Computer Interface
18th June 2003 Vacuum 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
18th June 2003 Vacuum Test Stand - IOC VME 64X Crate MVME167 (M68K) or PPC604 (Power PC) processor card (work on 68k now discontinued) IP Carriers - Hytec VICB Greenspring VIPC601 Serial Interface modules - Greenspring IPOctal - Hytec 8515
18th June 2003 Vacuum 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
18th June 2003 Vacuum Test Stand - Serial Devices 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
18th June 2003 Vacuum 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
18th June 2003 Vacuum Valve Control Crate Current preference - Allen Bradley Compact Logix Allen Bradley serial interface DF1 Protocol (Alan Honey)

18th June 2003 EPICS 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
18th June 2003 EPICS 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
18th June 2003 Vacuum 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.
