Hello,  
In Ignition reporting, I’d like to ideally simply list each transition of a boolean PLC tag from 0 to 1 and back and the amount of time, duration that it was in that state. Or at least just start with only duration on.  
I haven’t found the correct settings yet. In the data source, I tried using an aggregation mode of DurationOn, but it is returning the results shown, which is supposed to be seconds as I understand, which numbers don’t make sense. There are 7 transitions in state as show in the graph here, which is working. Am I using this aggregation of DurationOn incorrectly? Thanks much!
