Upgrade consists of replacing both the chassis and software of Fuel Controller and Sequencer new hardware and software for the Mark VIe. The system interfaces with the existing field devices and on-engine hardware that provide core fuel control, package sequencing, and protection. 

Applicable Turbine Models


Upgrade Benefits

  • I/O Ethernet capability has significant benefits:
    • Increased range of installation.
    • Increase network speeds and reliability.
    • No longer limited by controller location, simply by site wide intranet system scope.

  • Alarm Viewer and other trending applications have improved interfaces, much more user friendly.

  • Decentralized I/O modules utilize local processors, creating a net increase in process computing power and delivering higher performance.

  • Lower repair time because I/O modules can be replaced individually without disturbing entire system.

  • The multi system integration allows one easy to use, centralized system to control and monitor many turbine aspects. Also easier trouble shooting.

  • The new software upgrades optimize NOx and SPRINT Systems (see SPRINT page for full benefits):
    • Increased turbine power output.
    • Better engine efficiency and lower heat rate. 
    • Security updates to meet NERC/FERC regulations.
  • Increase Uptime
  • Enhance Operational Flexibility
  • Improve Maintainability

How it works

  • New Mark VIe combines Mark VI and GE Fanuc 90-70 into one controller

  • Significant I/O interface changes:
    • I/O interface no longer hardwired to controller, instead connected via Ethernet.
    • New 13 panel controller will incorporate the I/O interfaces from the old Mark controller.

  • The Mark VIe upgrade also includes:
    • New smaller, more compact, and more efficient UCSB CPU.
    • Windows 7 software upgrade (from Windows 98, 2000, NT, and XP).
    • Innova* replaced with touchscreen COMARK* or tower desktop HMI.
    • Latest core software logic upgrade.
    • Integrate single software application including: ControlST*, Work stationST*, and Workstation Alarm Viewer.
