Functional Description

IS230TNDTH4A is a Discrete TMR DIN-Rail Module developed by GE. It is a part of Mark VIe control system. The TMR (Triple Modular Redundancy) Mark VIe control architecture significantly enhances reliability and availability compared to a dual controller setup by incorporating advanced fault detection capabilities. In addition to the redundant features inherent in dual controllers, the TMR controller offers three independent outputs to all TMR I/O modules and employs a state variable voting mechanism rather than a jamming approach.

Features

• In TMR Mark VIe control system, all three controllers continuously receive inputs from the I/O modules across all networks and transmit outputs on their respective IONet interfaces. This constant communication ensures that each controller remains synchronized and updated with real-time data. Importantly, if a controller or network component experiences a failure, the system seamlessly continues operation without relying on fault detection mechanisms or requiring failover time.
• After transmitting output packets, each controller shares its copy of the state variables. These state variables represent the current state of the system, including parameters such as sensor readings and control signals. Subsequently, each controller independently processes the received state variables from the other controllers, employing a voting process to determine the most accurate data for the next operational cycle.
• This approach ensures that the TMR Mark VIe control system maintains robustness and continuity even in the face of component failures or network issues. By leveraging triple redundancy and intelligent data processing techniques, the system maximizes reliability and availability, crucial factors in critical applications where downtime is not an option.

Frequently Asked Questions

 

What is IS230TNDTH4A?
It is an Discrete TMR DIN-Rail Module developed by GE

Why is triple redundancy essential in critical applications?
Triple redundancy provides multiple independent channels for data transmission, ensuring that the system can tolerate failures without compromising functionality. This redundancy minimizes the risk of system downtime and enhances reliability, making it ideal for critical applications where uninterrupted operation is imperative.

How does the TMR approach differ from traditional fault detection mechanisms?
Unlike traditional fault detection mechanisms that rely on detecting failures and triggering failover processes, the TMR approach proactively maintains redundancy and continuously processes data, allowing for seamless operation without the need for failover time or explicit fault detection.
