  1. Follow-up from the last DCS workshop Answers and recommendations Alice DCS workshop, Colmar, 21.06.2004

  2. Q1:Is there any simulator of the Wiener, Iseg, CAEN? • Official releases software(Wiener, Iseg, Caen..) simulating the hardware behaviors do not exist • Framework does not support any kind of hardware simulator also • There are different users who developed their own simulators, but the correct behavior of the hw is difficult to achieve. • The general recommendation is to use the official OPC servers releases, together with the Framework implementation of the devices • For local needs one can use the PVSSsim manager to generate different DP values. Alice DCS workshop, Colmar, 21.06.2004

  3. Q2: CAEN OPC loosing configuration? • Clarification: CAEN OPC does not loose configuration !!! • “Device simple configuration” is general to all the devices implemented in Framework • So far there is no method to verify the previous configuration • This is still a subject of discussions in the FWWG (Framework Working Group) • A decision has not been taken yet, as the implementation is not a straightforward one Alice DCS workshop, Colmar, 21.06.2004

  4. Q3:Wiener firmware problems(1) • Wiener have released several firmware. • For PL500(F8)and PL6021(F8) the last release is UEP500(6021)2.12 and CAN 1.04 • As mentioned many times the Wiener OPC server 1.6 works very well for this firmware • Different users reported the existence of unphysical channels which reside in the current firmware • These behaviors should be reported immediately to the Wiener company, as they are the only ones responsible with the firmware upgrades Alice DCS workshop, Colmar, 21.06.2004

  5. Q3:Wiener firmware problems(2) • Special attention should be given to the correct connection of the CANbus to the 9D-Sub connectors • The correct resistor termination should be applied for the corresponding cable length and CANBus speed • Connectors with the incorporated termination can be bought from different companies (ex: ERNI) • Also the OPC configuration file should agree with the configuration loaded to the micro controller of the PS (namely Canbus address, speed) Alice DCS workshop, Colmar, 21.06.2004

  6. Q3:Wiener firmware problems (3) Alice DCS workshop, Colmar, 21.06.2004

  7. Q3:Wiener firmware problems(4) • More documentation can be found: • http://itcofe.web.cern.ch/itcofe/Services/Fieldbus/CAN/Cabling/documents/DR303-1V111.pdf • “Standard CANBus signal cables for Alice DCS” R.V.Vlugt Alice DCS workshop, Colmar, 21.06.2004

  8. Q5: TOF Trending tool poor and inaccurate (1) • PVSS trending tool is mainly an online monitoring tool • Data analysis features (like average, errors…) are not implemented • If these analysis are needed a simple method will be to export the data to an ascii file and analyze with other tools like root, excel… • PVSS trending tool is not simple to be use by non-specialist, but the Framework trending tool was created to make things easier for users Alice DCS workshop, Colmar, 21.06.2004

  9. Q5: TOF Trending tool poor and inaccurate (2) • http://itcobe.web.cern.ch/itcobe/Projects/Framework/welcome.html • A short tutorial document can be found at the DCS web page Alice DCS workshop, Colmar, 21.06.2004

  12. Q6:TOF PVSS security • Generally one have in the PVSS log view panel messages like • If the manager receives an invalid message from an computer, it cuts the communication with the unknown computer and prints its action in the log viewer • To avoid this type of illegal connection, for each manager one can define an “IP access list for TCP server sockets” • Documentation about this topics can be found in System management section PVSS00databg (1), 2004.06.14 19:05:21.796, SYS, INFO, 6, Initialization by Data Manager finished PVSS00valarch(0), 2004.06.14 21:02:08.835, SYS, INFO, 0, Lost connection to c199196.ppp.asahi-net.or.jp during initialization due to an illegal message format. PVSS00valarch(0), 2004.06.15 04:19:28.914, SYS, INFO, 0, , Lost connection to pcpdpas1.cern.ch during initialization due to an illegal message format. Alice DCS workshop, Colmar, 21.06.2004

  13. Q7: SPD Elmb, Wiener problems(1) • Elmb fake problems • “Elmb ADC operational “ panel is there to make possible changes during the operation • Changes in settings are preferably to be saved in the RAM and not in the EEPROM • One can write in EEPROM maximum 10000 times, but one should not exaggerate • One should not configure the EEPROM in the [init] section of the OPCCanServer.cfg file Alice DCS workshop, Colmar, 21.06.2004

  14. Q7: SPD Elmb, Wiener problems(2) • Wiener: it is strongly recommended to use the Wiener OPC latest release. • SliC is no longer supported; couldn’t reproduce the errors in our lab • The problems regarding the Wiener firmware should be close monitored by the Wiener company Alice DCS workshop, Colmar, 21.06.2004

  15. Conclusion • It is highly recommended to use the Framework components and the official OPC server releases • Any bug or problem in these two should be reported to us or to IT-CO Alice DCS workshop, Colmar, 21.06.2004
