Features:
- Processor base unit
- Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
- Hardware Implemented Fault Tolerant (HIFT) architecture
The Trusted TMR processor is a fault-tolerant design based on a Triple Module Redundancy (TMR) architecture, operating in a synchronous configuration. Figure 1 illustrates the basic structure of the Trusted TMR processor module in a simplified manner.
The module comprises three Processor Fault Isolation Regions (FCRs). Each FCR contains an NXP PowerQUICC® II™ series processor and its associated memory (EPROM, DRAM, Flash ROM, and Flash RAM), memory-mapped I/O, a voter, and glue logic. Each processor FCR employs a 2/3 (2oo3) read permission voting mechanism to vote on the memory systems of the other two processor FCRs to eliminate operational discrepancies.
The T9100 ICS triplex Processor base unit may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The three processors in this module are responsible for storing and executing applications, scanning and updating I/O modules, and detecting system faults. Each processor executes applications independently but operates synchronously with the other two processors. Each processor has an interface that includes an input voter, discrepancy detection logic.
Safety Instrumented Systems (SIS): Used for high-integrity safety functions such as Emergency Stop (ESD), Fire and Gas (F&G) detection, and Burner Management Systems (BMS).
Critical Process Industries: Deployed in oil, gas, chemical, and petrochemical plants where continuous operation is critical for safety and production.
Power Generation: Used in nuclear, hydro, and coal-fired power plants to manage critical control loops.
Transportation and Infrastructure: Used for railway signaling, traffic control, and pipeline monitoring.
Redundancy Management: Supports 1oo1D, 1oo2D, and 2oo3D configurations, ensuring system continuity even if a processor fails.
