I had a question from a client about some ProcessBook Data Set settings and so far I have not managed to find the definitive guide in the user manual or on in any articles on PI Square so I was hoping someone could point me in the right direction please.
In reference to the screenshot below, what my client would like to know is:
1) What is the difference in the configuration of using the 'TagAvg' function in the expression vs. using the 'Average' column from the 'Data Set Columns' list?
2) If they use the time ranged Data Set Columns does the 'Calculation Interval' setting applied for the range?
3) Does the calculation value get updated and sent to the display at the rate of 'Refresh Interval'?
4) What is the 'Interval Sync Time', is it an offset for the calculation? If so how does it work?
Apologies if this is covered clearly in the documentation - if it is can you please point me in the direction of it.
