What is the relationship between Input Sampling, Display update rate (Trend interval), Recording interval, and Archive Interval?
A. There is no relationship. Input sampling is 8hz (Fixed) while the display rate is maximum 8Hz for trending and 1Hz for numerical data. The archive interval is configurable between Hourly and Monthly or Automatic, which selects the best option depending on the current operating conditions, e.g. for a media card with 32Mb as opposed for one with 1Gb.
