I want to count the number of minutes/hours does a specific tag stay on a certain range...
For example, if I have 3 Temperature ranges: Less than 20°C, Greater than 20°C but less than 50°C and greater than 50°C
I need to have 3 PI Performance Equations using PROCESSBOOK that will determine how long does a tag stay on every particular range.
To make it easier to visualize, I need to come up like the one I attached
TIA 
Regards,
Cesar
