You can try below expression
If CompressorStatus=“Loaded” and (PrevVal(“LoadTag”,”*”)=PrevVal(“LoadTag”,PrevEvent(“CompressorStatus“,PrevEvent(“CompressorStatus”,”*”))))
Hi Lal... sorry for my lack of response to your quick response This equation works for me but I have a lot of false alarms it could be the timing on my tags (Status and Load). I am still monitoring the tag using your calculation and trying different scan rates on my tags. Any suggestions on this may help.
thanks in advance for your help,
Can you explain a little more what you mean by false alarm? Do you mean Event Frames opening and closing when they shouldn't?
Maybe a screenshot of the Event Frame configuration as well as the data in the input PI Point would help.
