  1. ALICE Control System July 08

  2. Introduction • Hardware Involved - • IOC’s • Other Systems • Network • Servers & Consoles • Applications • How to find them • How to specify what you want • History / Strip tool • Backup and Restore

  3. Control Station

  4. CS1 - Injector • CS1A – Serial • Radiation Monitors • PSU control • Motor Control ( whole machine inc Laser) • Injector Ion Pump control • Gun PSU • CS1B • Analogue control & readback • Status and interlocks – Magnets, Vac, laser shut, gun PSU, Cryo RF permit, Booster Valves

  5. CS2 – Injector ST1 & AR1 • CS2A – Serial • BPM switch unit • PSU control • Motor Control ( RF still Used ?? ) • Ion Pump control • Beam Loss / Protection readback • CS2B • Analogue control & readback • Status and interlocks • Hall probe readback (All the Machine) • BPM Readback (All the Machine) • Beam Loss / Protection control (All the Machine)

  6. CS3 – ST2 THZ FMU • CS3 • RF DIO • Analogue control & readback ( some RF) • Status and interlocks

  7. CS4 – ST3 AR2 ST4 CBS • CS4 • RF connection to S7 PLC • Analogue control & readback • Status and interlocks

  8. CS5 – Laser • CS5 • Pulse delay via GPIB • Charge counter • Attenuator

  9. Other Systems • Cryo PC – OPC server – Web Interface • Blade IOC in the control room • PS IOC’s Rack Room

  10. Network • Network LHS = site network RHS = Controls Network • Two network locations – Rack Room, Control Room

  11. Requests for new Control • Request by email with a sketch of what you want

  12. Requests for new Control

  13. Servers and Consoles • Erlpserv1 – Main server all control system configuration • Erlpserv2 – History data • 2 Consoles User = console Pw= console • 2 Laptops User = pcon Pw = control • Must be connected to the control network. • Some displays will be too big. • Main Menu – on all consoles • Close & restart Main Menu to get updates

  14. Control Synoptics • Control synoptics accessible via Main Menu • Commonly used synoptics are: • Injector • Vacuum • 500kV Power Supply • Laser • Magnets • Machine • Radiation Monitors • Vacuum • Magnets • Diagnostics • Personnel Safety • Machine Synoptics • RF • Linac, Booster, Buncher control

  15. History Web Interface • Main Menu -> History -> Web Interface • Used to retrieve archived data values for EPICS channels • Type PV name into ‘Names’ text box • Set date/time (US format) in start/end times drop down boxes • Choose output format • Plot • Various spreadsheet formats • Press ‘Get’ button • Can retrieve multiple EPICS channels at same time • Can use patterns to search for EPICS channels • If a channel is missing, please contact us to add it to history

  16. StripTool • Main Menu -> History -> StripTool • Used for real-time plots of EPICS channels • Type PV name into ‘Plot New Signal’ text box • Press ‘Connect’ button • Graph appears with real-time plot • StripTool Control Window • Curves Tab • Can modify precision (decimal places), logarithmic plot, mix and max limits • Controls Tab • Can modify sample rate, graph colours etc

  17. Backup & Restore Tool (BURT) • Main Menu -> Commissioning -> Back-Up and Restore Tool • Used to create and restore snap-shots of EPICS channels values • Request Files • Plain text file with list of EPICS channel names • Stored on Apsv4 which is samba mounted to both consoles at /home/Apsv4_astec_sambaShare directory • Backup button creates a snapshot of values for the EPICS channels specified in a request file • Restore button restores EPICS channels values from the values stored in a a snapshot file
