  1. SVD DAQ status in 2003and things to do in 2004 Y. Ushiroda (KEK) Dec. 25, 2003 @ SVD meeting

  2. No. of Fatal Errors October Timeout Error total : 90 Double Buffer Error total : 280 EvTAG inconsistent among threads total : 50 Null read total : 10 PPCI Reset Error total : 2 NSM Error total : 15 Unregistered Error total : 1 Dock Temp : 1 TTM monitor TIMEOUT : 104 End Ring Temp : 57 End Ring monitor Timeout : 93 PC monitor Timeout : 1168 Keeping Busy : 298 November Timeout Error total : 44 Double Buffer Error total : 97 EvTAG inconsistent among threads total : 41 Null read total : 27 No available data total : 4 PPCI Reset Error total : 1 End Ring Temp : 14 Keeping Busy : 90

  3. December Timeout Error total : 65 Double Buffer Error total : 27 EvTAG inconsistent among threads total : 136 Null read total : 24 No available data total : 1 NSM Error total : 12 TTM monitor TIMEOUT : 84 Keeping Busy : 53 f PC hang up / NSM trouble (?) f TTM firmware modification f NSM trouble f NSM trouble Rare troubles Dec.05 FATAL from [SVD] MonTA_MONTA's busy flag is set. : 8 Dec.13 FATAL from [SVD] Nsmd in power supply looks dead. VERY danger! FATAL from [SVD] Cannot open NSM data for Endring Temperature Monitor. Dec.13 FATAL from [SVD] Failed in HV/LV turn off. Trying again... FATAL from [SVD] PANIC: Failed in HV/LV turn off. Call SVD expert. Dec.13,21 FATAL from [SVD] PS current exceed limit f MonTA firmware vanished (?) f NSM trouble f NSM trouble

  4. Typical Down Time per Error Well-known fatal errors PC Hang up Rare troubles 1 min Shifter’s travel time + 7min Till we understand what’s wrong

  5. To do list • Fix TTM firmware & Back board delay EvTAG inconsistent Parity errors etc. • Ask CDAQ to wait more 6 sec. g e.g. 12 sec. may reduce Keeping Busy • Replace P-PCI Null read, PPCI reset error • PC reset by expert shifter Simplify the procedure ( John’s system + NSM ) • Robust hand shake Ask again before issuing a fatal error g Timeout error • Ask Nakao-san to debug NSM in SVD local net
