Duplicate Data

PME does not log duplicate data records in the historical database. Data records are considered duplicates if they are logged for the same measurement on the same source at the same time.

For special applications, there is an option to enable duplicate data collection in PME.

To enable duplicate data collection:

1. In the ION_Data database, in the dbo.Registry table set the SaveDuplicates parameter to "1" .

Note: The duplicate entries are stored in the "DataLog2Duplicate" table in the ION_Data database and are only accessible through the tabular report in Reporter, through RegGen, and through direct database access.
