I want to calculate number of times a valve has opened in PI Analytics..The valve values 0(close) and 1(open)..The analysis should only count for a defined period when value is 1..

Create an analysis to monitor the valve:

if BadVal('Valve') then

NoOutput()

else if 'Valve' = 1 and PrevVal('Valve') = 0 then

total('ValveCounter',1)

else

noOutput()

The output is sent to the 'ValveCounter' attribute.

The analysis can be event triggered on 'Valve'

Thankyou for your reply.

How can we give window for each month that it tells number of times it opened in a month?
