Hi,

 

I am currently working on how to count the alarm rate of each machine (etc. how many times the "active" status turned on for the past 10 mins)?

I am using PI AF 2015 R2 and am still very new to PI system. I am thinking to read the alarm status, as long as it is "active", it will +1 to a counter tag. Then use numofchanges function to calculate the total change. So far, I have no luck getting it correct, the value I obtained does not tally with the actual alarm rate.

 

Thanks alot !
