Hello all,
We are using a PI Server as a replacement for our DeltaV Continous Historian. I am DCS Engineer and not PI guru.,
I am reading here on page 13 http://www2.emersonprocess.com/siteadmincenter/PM%20DeltaV%20Documents/Whitepapers/WP_PIProtocolConv_FAQ.pdf
" For example, if a parameter is collected at a 1-second sample rate, the Protocol Converter will retrieve 5 samples every 5-second
period. If a parameter is collected at a 5 second sample rate, the Protocol Converter will retrieve 1 sample every 5-
second period. "
Does this mean on the PI chart, the data will be displayed for every second during that 5 second interval, or does PI take an avearage of the 5 data points during the 5 second period.
I am trying to make sure I understand how often PI displaying the data on the chart for pressure spikes analyzes. I want to make sure we don't miss quick pressure spikes.
I have a few questions:
Thank you kindly
