Chanel Event function

[Brad_Turpin · Accepted solution]

Hi Estefania,

The error you got was due to the fact that some channels were analyze which had no 0..1 or 1..0 transitions in them.  I ammended to code to just ignore such channels.  I also changed the code to only analyze channels based on whether the channel name contained a particular ChnNameMatch string in it (the string comparison is carried out in lower case always).  I also edited the code to flag channels that were filtered with a "Filtered" text in their "Description" property, so you can easily see if a channel has been filtered by the script.  You will need to change line 2 below to the "savings" string or any other you want to analyze-- there were no such channels in the 2 data files you sent me.

MinDuration = 100 '60*60 ' seconds
ChanNameMatch = "boiler 1 m2g"
WndShow "VIEW"
Set Group = Data.Root.ActiveChannelGroup
Set TimeChannel = Group.Channels(1)
FOR Each BoolChannel In Group.Channels
  IF InStr(LCase(BoolChannel.Name), ChanNameMatch) > 0 THEN
    ChnComment(BoolChannel) = "Filtered"
    EventList = ChnEventDetectionWindow(TimeChannel, BoolChannel, 0.5, 1.5)
    nMax = ChnEventCount(EventList)
    FOR n = 1 TO nMax
      P1 = EventList(n-1, 0)
      P2 = EventList(n-1, 1)
      Duration = TimeChannel.dValues(P2) - TimeChannel.dValues(P1)
      IF Duration < MinDuration THEN
        Call BoolChannel.SetValues(0.0, P1, P2-P1+1, 0)
      END IF
    NEXT ' n
    EventList = ChnEventDetectionWindow(TimeChannel, BoolChannel, -0.5, 0.5)
    nMax = ChnEventCount(EventList)
    FOR n = 1 TO nMax
      P1 = EventList(n-1, 0)
      P2 = EventList(n-1, 1)
      Duration = TimeChannel.dValues(P2) - TimeChannel.dValues(P1)
      IF Duration < MinDuration THEN
        Call BoolChannel.SetValues(1.0, P1, P2-P1+1, 0)
      END IF
    NEXT ' n
  END IF ' BoolChannel
NEXT ' BoolChannel

I also changed the DataPlugin to use the text to the left of the pipe character ("|") in the channel name as the group name.  This made it easier for me to use the same VIEW layout to analyze multiple CSV files from you.  Please detach and double-click on the attached newer version of the emendezcampa_CSV data file, click on the "Yes" button to overwrite the previous version, then use this DataPlugin whenever you load these data files.

Many thanks Brad. Everything works now.
