    MicroNet TMR Control System for Turbines and Compressors

     

    Woodward's MicroNet TMR (Triple Modular Redundant) controller is a customizable digital control platform that reliably controls and protects steam, gas turbines, and compressor trains used in system-critical applications where the chance of a safety issue or large economic loss may be possible.

    MicroNet TMR’s superior architecture and diagnostic coverage combine to create a system with 99.999% availability and reliability. The MicroNet TMR can be applied as a component of protection and safety systems to allow the overall system to meet IEC61508 SIL-3 compliance standards. IEC61508 calculations and application assistance are available upon request. 

    As an independent company, Woodward and our partners are able to provide full service, support and upgrades. We take great pride in customer support and continue to support fielded products for as long as parts are available. When upgrades are required, our OEM and Channel Partners are able to provide upgrade services on all controls.

    Through standardization and attention to software evolution, Woodward’s partners are able to adapt 1990’s software into today’s advanced control platforms with minimal or no changes required. Our world class software environment allows for updates to be done in GAP or imported as single blocks from other commonly used software environments including Matlab, C++, etc.
