3.3.3.3 Historian
The Mark VIe Historian computer runs ControlST software including Historian reports, the WorkstationST application, and
Trender, and can be configured for PI or Proficy data exchange to an external database server. The Historian is a data archival
system based on client-server technology, used for data collection, storage, and display of process data. Flexible tools enable
the operator to quickly generate custom trends and reports from the archived process data. The Historian combines
high-resolution digital event data from the Mark VIe controllers with process analog data, creating a sophisticated tool for
investigating cause-effect relationships.
The Historian receives data from the controllers over the UDH. The HMIs and other operator interface devices communicate
to the Historian through the PDH. Network technology provided by the Windows operating system allows interaction from
network computers, including query and view capabilities, using the Historian Client Tool Set. The interface options include
the ability to export data into spreadsheet applications.
3.3.3.4 Power Conversion Controllers
GE Brilliance* solar inverter and legacy wind power conversion controllers can reside on the integrated control system UDH,
and are configured with a common ToolboxST application.
3.3.4 Control Data Highway (CDH)
A second UDH or redundant Ethernet Communication known as the Control Data Highway (CDH) allows two separate
controllers to communicate with each other. The second CDH Ethernet can be added to a control system currently using the
other UDH Ethernet port. The following table displays requirements for hardware setup.
Note To configure a CDH, refer to ToolboxST User Guide for Mark Controls Platform (GEH-6700 or GEH-6703), the
section Networks.

Ethernet Connection
Each controller connects though the second Ethernet port using a single cross-over
category 5 network cable.
The simplex controller connects to the second Ethernet ports of both the <R> and <S>
controllers of the dual system using a category 5 network cable through a network
switch.
The simplex controller connects to the second Ethernet ports of <R>, <S>, and <T>
controllers of the TMR system using a category 5 network cable through a network
switch.
The <R> and <S> controllers of each system connect using a category 5 network
cable through a network switch.
The <R> and <S> controllers of the dual system connect to the <R>, <S>, and <T>
controllers of the TMR system using a category 5 network cable through a network
switch.
The <R>, <S>, and <T> controllers of each system connect using a category 5
network cable through a network switch.
With the TMR and TMR configuration, the customer does not have to use the network
if all EGD exchanges run at frame rate.
