I have a pump (on/off/on/off). When I bring the PI tag in as a String or Int16, and attempt to find the TagMin, it says that it can't do a summary calculation on non-numeric data. the underlying data from the PLC is a 1 or 0, and then the digital set displays the text. All I want is the raw value?
Tag Pump1 comes in as <Anything>, probably should be String
Tag Pump 1 Digital Status comes in as an Int16
All I want to know is if the value went to "OFF" or 0 in the last 120 minutes. Seems simple.....
Suggestions?
You can try something like...
if 'Pump 1'="OFF" and TimeStamp('Pump 1')>'*'-'-2' then EventCount('Pump 1','*','*'-'-2') else NoOutput()
