The MicroNet TMR® (Triple Modular Redundant) controller represents a significant advancement in digital control technology, designed to provide unparalleled safety, reliability, and precision in critical industrial applications. With its state-of-the-art architecture, the system ensures that steam turbines, gas turbines, and compressor trains operate efficiently and safely, even in the event of single-point failures.
One of the most impressive aspects of the MicroNet TMR is its fault tolerance capabilities. The system operates using a 2-out-of-3 voting architecture, ensuring that accurate decisions are consistently made. Each kernel section (A, B, C) operates independently, maintaining system integrity despite failures. This design allows for the failure of individual components, such as CPUs or I/O modules, without disrupting overall system functionality. For example, with CPU fault tolerance logic of 3-2-0, the system can function normally even if one CPU fails, while ensuring a safe shutdown with multiple CPU failures.
The MicroNet TMR system is built for high availability, boasting 99.999% reliability. Its modular architecture with online replaceable I/O modules enhances system uptime. Furthermore, the high-density modules and integrated application programs provide first-out indications and time-stamped event data, which significantly reduce troubleshooting time. For instance, discrete events are time-stamped within 1 millisecond, while analog events are captured within 5 milliseconds.
Another key feature of the MicroNet TMR system is its versatility in programming. The system supports IEC1131-3 compliant programming, including Function Block, Sequential Function Chart, and Ladder Logic. This flexibility allows users to tailor control solutions to specific industrial needs.
Moreover, the system’s open-architecture facilitates seamless integration with plant DCSs, HMIs, and distributed I/O devices. Multiple communication ports and protocols, such as Ethernet, RS-232/-422/-485, and Modbus, ensure robust communication capabilities. This versatility enables efficient system operation and simplifies service and troubleshooting.
The MicroNet TMR control system has been successfully applied in various critical applications, including refrigeration compressors, methane compressors, and turbine safety systems. Its compatibility with Woodward standard MicroNet I/O modules enhances application flexibility, providing comprehensive control solutions for complex industrial processes.
In conclusion, the MicroNet TMR® control system stands out for its superior reliability, fault tolerance, and flexible programming capabilities. It ensures the safety and efficiency of critical systems, making it an ideal choice for turbine and compressor OEMs and operators seeking robust, high-availability control solutions.
