Replicate tags from one Historian to another

You can replicate tag information in a Historian from one Historian to another. This allows you to replicate tag data from one or more Historians (known as tier-1 historians) to one or more other historians (known as tier-2 historians). You can replicate tag data to the same server as the tier-1 historian.

You can replicate tag data directly using simple replication, where the tag information is replicated directly to the tier-2 historian. For simple replication, every value for a tag is copied. You can also set up summary tags that receive a summarized version of the tag data.

You can drill down from a source tag to its replicated tag or drill up from a replicated tag to its source tag. You can add a source tag with its replicated tag or a replicated tag with its source tag in the active trend chart. You can also replace a source tag with its replicated tag or a replicated tag with its source tag in the active trend chart.
