Hi,

I'm struggling with this question for a long time.

We are monitoring Gas analysers and the moment an analyser value passes a certain range, it is a rule this analyser has to be checked immidiatly.

Now we monitor this by looking at trends and and see if the analyser(s) has been exceeding the max limit over the precious period of 8 hours.

It would be helpfull if a calculation Tag would show automatically a total count of events over the last 8 hours (every event should count as one, does not matter how long that event was).

Example:

Analyser: AI-301

Max limit: 20

Events that happend from now and 8 hours back: 

Thanks in advance.

André
