Trend Copy to clipboard or SaveAs in process analyst view

Exports from Process Analyst, like SaveAs and Copy to Clipboard, copy the interpolated data from the PA view on screen, not the actual trend data. Accurate Trend data export can be achieved with custom Cicode routines built around one of the TrnExport***() functions, or with external tooling like the ones you can find in the Citect Toolbox Forum on this website (https://softwareforums.aveva.com/citect_community/cit-toolbox/).

Yeah, I regularly export trend data from the Process Analyst, and I do so by first setting up a custom analyst view (.PAV) view to export from, which includes both the correct time span and the correct corresponding "Number of Samples" (default value = 300) set in the trend properties, in order to get data that starts on the right time boundary and with the interval between samples that I need.  It's a bit of a clunky workaround but it does the job.   Not really a good option if you want to export a large quantity of data at once though.
