Rockwell ICS Triplex T8233

Description

Rockwell ICS Triplex T8233

The Rockwell ICS Triplex T8233 is a TMR main processor module designed for applications requiring the highest levels of safety and high availability.

 

1. ‌Core Function: Main Processor Module‌

   • The T8233 serves as the “brain” of the Trusted TMR control system. It executes user-programmed safety control logic.

2. ‌Core Architecture: Triple Modular Redundancy (TMR)‌

   • This is the T8233’s defining characteristic. The module integrates ‌three completely independent, parallel-running processor channels‌ (typically based on Motorola 68000 series or compatible processors).
   • Each channel possesses its own dedicated:
     • Processor (CPU)
     • Memory (RAM, ROM/Flash)
     • Input/Output (I/O) communication interface hardware
     • Power supply
     • Internal bus
   • All three channels run the ‌identical‌ user program ‌synchronously‌.

3. ‌Safety Mechanisms: High Availability & Fail-Safety‌

   • ‌Voting:‌ The system performs ‌majority voting (2-out-of-3 or 2oo3)‌ at critical points (e.g., output driving, communication, internal diagnostics). If one channel fails (hardware fault, software error, external interference), the correct result from the two healthy channels prevails, ensuring continued correct operation (‌High Availability‌).
   • ‌Diagnostics:‌ The T8233 incorporates extensive, robust online diagnostics, continuously monitoring each channel’s health (memory, processor, communication, power, etc.) and synchronization with the other channels. A detected faulty channel is safely isolated.
   • ‌Fail-Safety:‌ If voting cannot achieve majority consensus (e.g., two channels fail differently) or diagnostics detect a severe system error, the system enters a predefined ‌Safe State‌ (typically shutdown or safe mode), ensuring safe process termination (‌Fail-Safety‌).
   • ‌SIL 3 Certification:‌ Trusted TMR systems (including the T8233 module) are designed to meet the highest safety requirements, typically achieving ‌Safety Integrity Level 3 (SIL 3)‌ certification under ‌IEC 61508‌ and ‌ISA S84.01‌ standards. This validates extremely low probability of failure and safe operation in the most demanding hazardous scenarios.

4. ‌Key Features:‌

   • ‌High Reliability:‌ TMR architecture and online diagnostics drastically reduce the probability of system failure due to single-point faults, ensuring continuous operation.
   • ‌High Availability:‌ Supports hot-swappable maintenance. A faulty T8233 module (or any system module) can be removed and replaced while the system remains powered and operational, avoiding total system shutdown.
   • ‌Robust Processing Capability:‌ While processor frequencies may be lower than modern general-purpose controllers, it is highly optimized for executing critical safety logic with high efficiency and determinism. Logic capacity is typically measured in “safety interlocks” or ladder logic steps.
   • ‌Fault-Tolerant Communication:‌ Utilizes dedicated, highly reliable communication protocols for interaction with other Trusted system modules (e.g., I/O modules, communication gateways), often featuring inherent redundancy and voting mechanisms.
   • ‌Rugged Design:‌ Industrial-grade construction for harsh environments (vibration resistance, Electromagnetic Compatibility – EMC).

5. ‌Typical Applications:‌

   • ‌Critical Process Safety Systems (SIS – Safety Instrumented Systems):‌ Emergency Shutdown Systems (ESD), Fire & Gas Systems (F&GS/FG&S), Burner Management Systems (BMS), High-Integrity Pressure Protection Systems (HIPPS).
   • ‌High Availability Control:‌ Provides continuous control in applications where shutdown costs are extremely high, even during single faults.
   • ‌Industries:‌ Oil & Gas (upstream, midstream, downstream), Refining, Chemical, Petrochemical, Pharmaceutical, Power Generation (thermal, nuclear), Critical Infrastructure.

6. ‌Physical Form & Installation:‌

   • Typically a modular card installed in a dedicated Trusted system rack/backplane.
   • Communicates via the backplane with other Trusted modules (e.g., Power Supply Module PM8323; I/O Modules like ICD8233, AI8233, AO8233, DI8233, DO8233) and communication interface modules (e.g., CI8403 – Profibus, CI854 – Ethernet).
   • Requires dedicated Trusted system software (e.g., Trusted Configuration Tool – TCT) for programming, configuration, diagnostics, and maintenance.
