I have set up an mbbi CA process variable that is read every second (PPS) from a GPS device and I have defined enumeration tags.   The Archive Engine is recording every single reading, even though the GPS status rarely changes.    How does one stop this?
Please note:

 1. The mmbi record type does not have MDEL and ADEL fields

Have you checked with 'camonitor' to see if your PV is actually posting changes?

 2. Currently it is not an option to move to Archiver Appliance since this is a running experiment.

Any ideas?

Thanks
