CMS RPC Gas Loss Alarm
> the loss can be negative: can we have alarms on ABS value? 
> not used channels > disable from reading? disabled channels are automatically excluded? 
> blocked alarms on leaking channels > is it correct to block from Alarm tab of distribution PCO?

Gianluca:

• Data extraction from winccoa archiving. Not needed as it is the same data from Timber. Solved
• Fast method to check and set deadband, smoothing (winccoa and plc).
  • It's not fast but it's mostly automated, except the export of the config files. Presentation here: https://grigolet-eos.web.cern.ch/grigolet-eos/presentations/WinCCOA/DPE%20configs%20ALICE.slides.html
• Fast method to check alarms and warning levels
  • I could only find the data on CPC spec files but I couldn't find if there is the possibility to dump them from WinCCOA
• Improve the text in sms messages for alarm/warning to have a better understand of what is the issue
  • Michal?
• Alarms handling on elog:
  • I tested a script and dumped some alarms here: https://elog-epdt.web.cern.ch/Alarms/
  • System quite complicated because of cern-sso but we can test it in case
• Quick export of warning, alarms, forced items etc for each system
  • Discussed with Michal, waiting for reply
• Import of CPC device configs on production
  • Deadbands are in the spec file, so I suspect we cannot do it (without stopping everything) unless there is a dedicated feature. Asked to Michal, waiting for reply
• Development of the webmass software for read-out of gas temperatures
• Development of the webmass software for monitoring of the CANbus quality
• Development of an overview page in winccoa to show the Profibus and CANbus quality
• Any new test system (like the one of r134a recuperation)

Mara:

ALARMS

• Some alarms are not showed in the main panel, you need to open the system to see it
  > it is because of “Child to Parent” alarm in the module that is blocked
• Some alarms cannot be identified
  > slides Monday meetings with all the alarms to reconstruct together
• Block alarms notification (not the alarm itself) during maintenance
  > we could have a button to set the system in maintenance, with timer?

GENERAL

• Have an overview of each system with relevant parameters to see the situation at once
  > like exhaust page, maybe a button next to “Gas System”
     exhaust parameters, mixer flow/concentrations, pump status/opening, …

PLOTS

• Save a trend you made in “Dynamic Trend”, not everybody can do it
  > for Gianluca works in some systems, check if now it works or if it is a problem only of some systems (upgrade/not)
  > screenshot and put in elog (assign to Michal)
• Make modification in “Plot Configuration”, it can be opened but modifications are not applied for not-admin access
  > check if it can be made accessible to everyone
• Scale/Range problems with new software in “auto”
• Zoomed plot does not keep scale/time range, not updated with newly added trends

> flow value in mixer lines has no archiving
   is it necessary to keep? useful to trace back consumption (low+high flow), does not make much sense without archiving (reading is the same as XMFC
