  1. SNS Control Systems LANSCE (LANL) Trip Report Sept. 15, 2005 Ernest L. Williams Jr. Control Systems Group, ASD Oak Ridge National Labs (SNS)

  2. What did I do there? • Give a full day presentation and workshop on the use of Linux with EPICS • Install vxWorks Compiler 5.5.1 for Linux. • Configure an EPICS ready BSP for MVME2700 • Setup a Linux-based BootServer/OPI with an SNS style ADE. • Poke around the LANSCE Control Room a bit. • Eat Red and Green Chile.

  3. Attendees • Ernest L. Williams Jr. • Deb Kerstiens • Gary Carr • Jeff Hill • Eric Bjorklund • Martin Pieck • Peregrine McGhee • John A. Faucett • Hamid Shoaee

  4. LANSCE Controls Computer Hardware • Moving from Sun Microsystems to “commodity” PCs running Linux (e.g. RHEL) • They want to say good-bye to the Vax workstations as well • Move Front-End-Processors to VME-CAMAC, VME, and PLC-etherIp • Good-bye to the micro-Vax • When all of this is done the CA/Vax-gateways will no longer be needed. Pure EPICS is where they are headed.

  5. LANSCE Controls Software • Standardize on java for most of the high-level applications. There will still be TCL/TK apps running around as well. • They are very interested in XAL and plan to use it. This is something we pull from CVS before I left. • Stay with edd/dm for now. Let’s see what EPICS Office is going to do. • Move to Channel Archiver data collection and retrieval software • vxWorks 6.X (PowerPC targets)

  6. LANSCE Control Room • Currently the control room at LANSCE has Sun workstations driving an inverted-T of LCD panels. • Each LCD display is an independent monitor. • They operators are asking for Xinerama. • LANSCE uses shared Captive accounts. • This helps make a consistent and stable environment for the operators • The shared accounts are easy to manage. • Alarm system • Custom alarm software • Audible alarms for critical events
