Hi All,


I am struggling to work out how to count the number of time a PI value reads 0 in a defined time period. For the graph below i would like the output cell in excel display the number of times the value reaches 0 in the last 4 hours of running. I used 'calculated data' with the inputs as shown below however does not appear to work.

Any help would be greatly appreciated.
