Monitoring Controls System meeting on December 11, 2001


Attendance:
Andrea Bocci, David Dagenhart, Steve Hahn, Mark Knapp, Paolo Mazzanti, Oleg Poukhov, Fiodar Prakoshyn, Yeongdae Shon, Margherita Vittone, Marcin Wolter, John Yoh, JC Yun

NEWS:
Steve said the 'flying wire', which was run every an hour to measure beam position, won't be running any more. This had been a pain for shift crews and also source of inefficiency since they have to lower down the high voltages for the COT and Muon system. Hopefully, we do not need this any more. He also mentioned that the font size of detector names at the 'CDFGbAlarms' page needs to be reduced. When the page is reduced, the characters were chopped off.

SYSTEM:
David said the connection between APACS and iFIX was locked up several times during the last a few weeks on the CDFTEMP. He thinks it's due to the anti-virus run activated remotely, which was running everyday since a month ago. It shut down the pc 3 times completely and caused error for many more times. JC mentioned that Vnodes also suffered similar symptoms (2 times). Also the Gamma system failures and the errors at the Voltman might be linked to the fact.
Since they occured around 2:00AM when the anti-virus run was scheduled, it's most likely the culprit. Mark said there is no way to lower priority of the execution. We will plea to the Computing Division for a better way. For the time being we will be running it during day time when the experts are available to monitor and recover from failures.

ICLCLE:
Margherita said that systems: COT, PlugTemp, SVX, Cryo are in produciton mode while MUON and clorimeters are still in development stage. The Randy Herber's browser only dumps text. To figure out how to use graphics for the database data, Mario Spezziga would be good person to consult since he has some experience this problem with DBANA.
MUON:
Trigger Inhibit is working fine now. The new implementation of the heart beat checking improved the HVMON performance quite a bit. He needs fine tunning to complete.

PSM:
Marcin put in new iFIX pages which show power supply locations in the collision hall. He is now working on the web pages which shows all the channelsof power supplies for the calorimeters in one page, which was requested by Mike Lidgren.

CCU:
Oleg said the CCU system is ready to be monitored at the control room. There would be 6 more subsystems. The 3 systems: CSP, BSU, TSU use the CCU controller. The other 3 systems: CSW, MSK, CSX use the PISABOX controller. Heart beat checking for the systems will be about every 20 minutes. Magherita will help him out for the installation.

CLC:
Andrea said that he is improving the softwares for CLC. He wants the CLC, BSC, MNP systems to be controlled by the shift crews with CDFHVSummary page. The standby mode can be set at around 20%.
