Controls Commissioning Facility Advisory Committee Meeting Oct 30, 2007

1. Controls CommissioningFacility Advisory Committee MeetingOct 30, 2007 • IOC Engineering Team • Infrastructure and subsystems • Integration Testing • Lessons-Learned

2. EPICS Team • Ernest Williams • Kristi Luchini • Stephanie Allison (50%) • Till Strauman (50%) • Arturo Alarcon • Debbie Rogind (on loan from high-level apps) • Dayle Kotturi • Sheng Peng • Doug Murray • Stephen Schuh • Diane Fairley (on loan from high-level apps) • Judy Rock

3. Infrastructure and Subsystems • Controls Network was simply a subnet of the Office enterprise network. • One big Channel Access Domain • Used different CA ports to segregate development and production network • All files needed by the control system were on AFS. • Easy access to files: development and production were in the same tree.

4. Infrastructure and Subsystems (Cont’d) • Special AFS/NFS translator was used to provide NFS access to IOCs • Computer Infrastructure: • Boot Server based on the AFS/NFS translator. • Daemon Server: ran softIOCs and ChannelWatcher • Operator Consoles were managed by SCCS and used the AFS system as well. • OS: RHEL WS 4 (linux-x86) • EPICS: Version R3.14.8.2

5. Infrastructure and Subsystems (Cont’d) • IOC Infrastructure (EPICS: Version R3.14.8.2) • Targets: • MVME6100 (VME64-X) – rtems 4.7.x • uC5282 (stand-alone) – rtems 4.7.x • linux-x86 (soft-IOCs) – linux rhel-ws4 • Serial port system to connect to all IOCs: • Watch the boot process and/or debug IOC • Remote power Cycle for all IOCs mostly in place. • IOC Health Monitoring needs work.

6. Infrastructure and Subsystems (Cont’d) • Types of IOCs • SoftIOCs ran with high-reliability and uptime. • Number of softIOCs  ~12 • ColdFire (uC5282) IOCs: • BPMs are using the uC5282 and ran with high reliability especially with respect to Beam Synchronous Acquisition. (Qty  ~26) • LLRF are also using ColdFire and ran with good reliability. There is work to do to improve the beam synchronization acquisition. (Qty  ~28)

7. Infrastructure and Subsystems (Cont’d) • Types of IOCs • VME-based systems worked fairly well this commissioning period. (Qty  ~40) • Issues related to timing receiver boards (i.e. are under investigation) • Camera system vulnerable to timing glitches • Magnet IOCs still not using EVR due to an issue with interrupts.

9. Integration Testing • A plan was implemented to get more controls test time. Typically, the schedule seems to always squeeze the control systems test time. • We instituted a plan to allocate one day every week for controls integration testing and checkout as part of the beam commissioning schedule. • Integration testing was performed in close coordination and cooperation from operations and physics.

10. Lessons-Learned • Improve IOC Infrastructure and Management • Remote power cycle integration into EPICS for all IOCs • Standardized Test Plans to improve integration testing and coordination. (Optimize Testing schedule) • Move to production network to improve overall reliability and independence from office network. • Beam Synchronous Acquisition is very important for LCLS and uses the same infrastructure required for fast feedback. This infrastructure will be completed for LLRF, Toroids, and Bunch Length. • The systems that are using ColdFire + VME combination need to use a dedicated network and special driver for deterministic data transfer. Should not use Channel Access for this. • Configuration Management via relational database in the works • Not enough personnel resources to cover all systems.
