Hi there,
What is the most efficient way of determining the minimum value of a tag in a certain time period? Or even doing a test of counting how many datapoints there are below a certain value?
Cheers,
dinoken

For the minimum: Use the summary method of the PIData object.
For the event count: use an expression calculation.
We had a similiar thread some days ago and Rhys provided some source code.

Hey dinoken, As Michael pointed out, see this thread: http://www.rjksolutionsl..._Find-MinMax-Value.aspx
Some code in there for you to use and modify to suit your needs. Cheers, Rhys.  OSISoft PI System SpecialistsPI Consultancy on PI Systems, Analysis Framework, PI custom developments and all things PI.
