FAQS

• What are Safety Instrumented Systems?
  Safety Instrumented Systems (SIS) are independent control systems specifically designed to automatically restore industrial processes or equipment from hazardous states to safe states. Their core function is to provide safety-level protection, preventing catastrophic accidents such as fires, explosions, and toxic substance leaks caused by runaway process variables (e.g., excessive pressure, excessive temperature, liquid level overflow), thus ensuring the safety of personnel, the environment, and assets.
• What is Triple Modular Redundancy?
  Triple Modular Redundancy (TMR) is a high-reliability system design architecture that uses physical redundancy and majority voting mechanisms for fault tolerance. Its core principle is to use three identical hardware modules (such as processors and I/O channels) to execute the same task in parallel, and to compare the outputs of the three modules in real time through a "voter."
• What is an EWS?
  An EWS (Engineering Workstation) is a core dedicated computer in an industrial automation system used for engineering configuration, programming, debugging, and maintenance. It runs manufacturer-specific engineering software and serves as the primary interface between engineers and the control system. This software is used to create and download control logic, configure hardware, set up networks, manage databases, diagnose faults, and perform system simulations and tests.
• What are the typical modules that make up a Triconex system?
  A Triconex system typically consists of five main modules forming a complete triple modular redundancy architecture: The core is a triple master controller module that operates in parallel and performs cross-diagnostics via a bus; a TMR/duplicated input/output module (including analog, digital, and dedicated SOE event logging modules) responsible for signal acquisition and secure output; a network and communication interface module that isolates internal and external communication; a triple or dual power supply module providing highly reliable power; and the TriStation software development and maintenance workstation for engineering configuration, simulation debugging, and system monitoring.
• What is Triconex's layered communication architecture?
  Triconex's layered communication architecture is the core design for achieving secure isolation and data interoperability. It mainly includes three strictly isolated layers: the bottom layer is a closed, secure kernel layer; the middle layer is a secure, isolated interface layer; and the top layer is a controlled data mirroring layer.
