Core Functions

TMR Fault‑Tolerant Safety Logic

Three synchronized 32‑bit processors execute identical logic; 2oo3 hardware voting eliminates single‑point failures—critical for SIL3 ESD/F&G/BMS.

ECC Memory Integrity

ECC‑protected RAM/Flash corrects single‑bit errors and detects double‑bit errors, preventing data corruption in safety loops.

High‑Speed System Management

TriBus (4Mbps) ensures tight processor/I/O sync; 10–50ms scan times support fast safety responses.

Hot‑Swap & Online Maintenance

Replace modules without shutdown; TriStation 1131 enables online programming/firmware updates.

Comprehensive Diagnostics & SOE

Real‑time fault logging, ECC error tracking, and SOE for compliance; propagates alarms to DCS/HMI.

Applications

Oil & Gas: Offshore ESD/F&G; platform‑wide safety logic

Chemical/Refining: High‑integrity BMS/ESD; reactor safety control

Power Generation: Boiler BMS/Turbine TMC; critical turbine safety

SIS Upgrades: Replaces older Tricon processors (e.g., 3007) in legacy systems
