Overview

The T8111 Trusted TMR Processor is the core processing component of the ICS Triplex Trusted™ system, developed by Rockwell Automation (ICS Triplex). It uses Triple Modular Redundancy (TMR) with a 3‑2‑0 fault-tolerant architecture, meaning three processors run in parallel and can continue operation even if one fails.

The module features Hardware Implemented Fault Tolerance (HIFT), automatic fault handling, and time-stamped fault logging. It supports IEC 61131‑3 programming languages and integrates seamlessly with Trusted™ I/O modules via the Inter‑Module Communications Bus.

This processor is widely used in oil & gas, petrochemical, chemical, power generation, and utilities, where continuous operation and safety integrity are essential.
