Monitoring Controls System meeting on January 20, 2004


Attendance:
Steve Hahn, Andy Hocker, Dan Ryan, Yeongdae Shon, Margherita Vittone, John Yoh, JC Yun

NEWS:

  • Steve's transparancy.
  • SVX:
    Andy reported that there was an incident on Saturday when voltage read back of a ladder of SVX was zero - the actual voltage was OK. This caused the software trigger inhibit to fire. Since the state of the system is OK, the SVX button was still green and produced no audible alarms. On top of it, the shift crews could not find any information about the detailed status of the SVX. These information used to be on the old trigger inhibit picture which were not on display since a few months ago after trigger inhibit update.

    Andy was wondering how other subsystem handle this kind of situation where status of certain channels are different from that of the majority of channels. If you remember how you handle in your system, please send an e-mail to Andy so he could use it as an example. On Tuesday morning Steve produced a stripped down version of the trigger inhibit page to display only the SVX part.

    ICICLE:
    Margherita said she had installed a new version of OTL(Oracle Template Library) which can handle errors better. The system with the old version' used to crash when server was not running.

    She also made a request to upgrade the PC to solve the so called 'Larry's Time' problem. When the problem occurs, the remote time get confused with the local time.
