With AVEVA Historian, you can replicate tag information from one Historian to another. This creates a "tiered" relationship between historians. That is, the tier-1 Historian send its replicated data to a tier-2 Historian. Historian also supports multi-tier replication. Data originating at tier 1 can be replicated to tier 2, then again to tier 3, and so on. AVEVA Historian can replicate process data as well as alarms and events. |

AVEVA Historian supports two types of replication:
-
Simple replication
You can replicate tag data directly using simple replication, where the tag information is replicated directly to the next-tier Historian (for example, from tier 1 to tier 2). For simple replication, every value for a tag is copied. -
Summary replication
You can also set up summary tags that receive a summarized version of the tag data.
