Hi All

 

I'd like to ask what's the best way to use PI AF to calculate accumulative total running hours of a equipment since in service. And output value to a PI tag on an hourly basis.

I am thinking to use AF analysis to calculate each time the circuit breaker status change on the equipment, and totalise time duration into a PI tag.

But this approach isn't straightforward enough to achieve this simple aim. Must be a better way I don't know.

 

It would be great if anyone can share if there is a better approach available.
