Honeywell Experion LX Client Guide

This topology creates a dependency on the network infrastructure between the control system
and the external source. The reliability of this network should be taken into consideration
when planning this time hierarchy.
If the network between the external sources is reliable or local, then direct access to the
external (or local) device is recommended. This means that you only need one secondary
server. This is highly recommended for SOE configurations.
Domain topology
In the following diagram, the domain controller receives time from an external source. The
domain controller serves time to the redundant Experion servers, Flex Stations, and Console
Stations. An external source serves time to the C300 controller.
You should verify that the Active Directory/domain you link to uses a reliable external time
source. If an external source is not used, the internal CMOS of the domain controller (or PDC
Emulator) is used as the time source. This time source is not as accurate and will create
deviations in time seen throughout the hierarchy. Systems with strict requirements on
sequence of events should not implement this topology.
