FactoryTalk Historian To Historian Interface User Guide

Example Architecture for Historian to Historian within a Historian Collective

Tag attribute override parameters allow users to pass global settings that enable the interface
to identify and build its tag list without requiring the tags to be defined explicitly for
Historian to Historian. A detailed description of the tag attribute override parameters can be
found in section

Startup Command File

section of this manual.

Firewall Considerations

When a firewall separates the source and receiving Historian Servers for the Historian to
Historian interface users may want to run the interface outside of the firewall network. This
configuration requires that port 5450 be opened for incoming connections to the Historian
Server through the firewall. All outgoing connections from the Historian Server will require
that port 1024+ and greater are opened. Additional configuration information for
implementing a firewall can be found in our knowledge base (KB) article #2820OSI8 which
is available on our TechSupport website (

http://support.rockwellautomation.com

).

For the best security posture, Historian to Historian should push data out from the most
sensitive Historian Server. Enable buffering to eliminate the latency bottleneck.
