Can anyone share C#code sample(s) for getting the recorded values over a period of time? I cannot use AF SDK for reasons beyond my control. Any help much appreciated! I need to get the values from the PI archive over a period of time to do custom calculations. I assume some of the values can be returned from the archive as "Bad Data", "No Data", etc.? I have had this experience in the past with PI Data. For the Summaries2 method, can the duration be null or empty? I am interested in values calculated over all values between the start and end times, not over a small interval or duration.
Thanks for the patience with a newbie.
