Apparently only a 32MB CF card is available. We would like to trend pressure, flow, temperature etc. At the moment the trends are Realtime cyclic triggered at 1 second with 100 samples per screen. We would like to have archived trends going back a couple of weeks. My questions are. 1. How do we calculate how much memory will be used on the CF 32MB card for 1 second sampling? 2. What happens when the CF card is full? 3. Do the archive logs roll over? 4. Any information on setting up trends would be appreciated. Thanks In Advance Jim
