Overview

This connector is used for narrow tables/views that has at least a column representing a timestamp, a column representing the tag name/tag index and a column representing process data. The following is an example of a narrow table using a tag name column:

In the case where the table contains a tag index, instead of a tag name, a second table is used to establish the tag index/tag name relationship. The data above would be stored as follows:

In both the cases above, the data has been collected periodically every minute. Support is also provided for collections on events in which case the timestamp of the row will represent the time when the event occurred e.g., cycle end. A tag catalog is automatically created for tag selection.

For reporting purposes, a specified time can provide raw values and aggregates.
