My company uses wireless sensors to retrieve data and our engineers would like to be able to monitor the connectivity (Stale points) for each individual sensor.
Right now I am running a performance equation that looks at timestamp of PrevEvent function to determine if the point is updating as frequently as we expect with exception and compression. However, this equation looks at the archive and as our projects grow we will not want to store this much data solely to check for loss of data for each sensor point... I have had to lower exception and compression maximums in order to check as frequently as desired.
Does the "Stale and Bad Points" plug-in for SMT look at the snapshot instead of the archive (So only exception applies)? If so, is there a way to automate this to check for loss of data and use this information in multi-state process book symbols and notifications?
Any other ideas? Thanks!
