TRICONEX 2101语法错误不同于在运行时影响程序的错误。计算机编程中的许多逻辑错误没有被编译器发现，因为尽管它们可能在程序运行时引起严重的错误，但它们确实符合程序的语法。换句话说，计算机不能判断一个逻辑错误是否会产生问题，但它可以判断代码何时不符合语法，因为对语法的理解是编译器固有的智能。

TRICONEX 2101理解语法错误的另一个方面是，它们展示了与人类不同，计算机无法使用设计不完美的输入。一个句子或命令中缺少句号或逗号，或者一个单词中缺少两个互换的字母，都会使编译器困惑，使其无法工作。另一方面，人类读者可以发现印刷错误，并在他们阅读的上下文中理解它们。随着计算机在未来几十年的发展，工程师们很可能能够创造出能够处理某些类型语法错误的编译器和系统；即使是现在，在一些编译环境中，工具可以现场自动纠正语法错误。

Triconex系统的设计是为了在部件发生硬故障或内部或外部来源的瞬时故障时提供无差错、不间断的控制。容错性是通过整个系统的完全三层结构来实现的，从输入模块到主处理器再到输出模块。每个I/O模块都有三个独立的脚的电路。Triconex是施耐德电气的一个品牌，为安全、关键控制和涡轮机械应用提供产品、系统和服务。Triconex系统基于专利的三重模块化冗余（TMR）工业安全关闭技术。

Tricon是提供容错功能的最先进控制器

通过三模块冗余(TMR)架构。TMR在一个控制系统中集成了三个隔离的并联控制系统和广泛的诊断。该系统使用三选二投票，以提供高完整性、无错误、不间断的过程操作，无单点故障。

Tricon控制器使用三个相同的通道。每个通道与其他两个通道并行独立地执行控制程序。专门的硬件/软件投票机制对现场的所有数字输入和输出进行鉴定和验证，而模拟输入则经过中间值选择过程。因为每个通道都与其他通道隔离，所以任何通道中的单点故障都不会传递到另一个通道。如果一个通道上确实发生硬件故障，则其他通道将覆盖该故障。同时，故障模块可以在控制器在线时轻松移除和更换，而不会中断过程。

TRICONEX 2101 syntax errors are different from errors that affect programs at run time. Many logical errors in computer programming go undetected by compilers because, although they may cause serious errors while the program is running, they do conform to the syntax of the program. In other words, the computer can't tell if a logical error will cause a problem, but it can tell when the code isn't syntactic, because understanding syntax is inherent in the compiler's intelligence.

Another aspect of TRICONEX 2101's understanding of syntax errors is that they demonstrate that, unlike humans, computers cannot use imperfectly designed inputs. Missing periods or commas in a sentence or command, or two interchangeable letters in a word, can confuse the compiler and make it unable to work. Human readers, on the other hand, can spot typographical errors and understand them in the context in which they read. As computers evolve in the coming decades, engineers will likely be able to create compilers and systems that can handle certain types of syntax errors; Even now, in some compilation environments, tools can automatically correct syntax errors on the spot.

The Triconex system is designed to provide error-free, uninterrupted control in the event of a hard component failure or transient failure from internal or external sources. Fault tolerance is achieved through a complete three-tier structure of the entire system, from the input module to the main processor to the output module. Each I/O module has three separate legs of the circuit. Triconex, a brand of Schneider Electric, provides products, systems and services for safety, critical control and turbomachinery applications. The Triconex system is based on patented Triple Modular Redundancy (TMR) industrial safety shutdown technology.

Tricon is the most advanced controller offering fault tolerance

With three-module redundancy (TMR) architecture. TMR integrates three isolated parallel control systems and extensive diagnostics in a single control system. The system uses two out of three voting to provide high integrity, error-free, uninterrupted process operation with no single point of failure.

The Tricon controller uses three identical channels. Each channel executes the control program independently and in parallel with the other two channels. A dedicated hardware/software voting mechanism identifies and validates all digital inputs and outputs in the field, while analog inputs go through an intermediate value selection process. Because each channel is isolated from the others, a single point of failure in any channel is not transmitted to another channel. If a hardware failure does occur on one channel, the other channels will override the failure. At the same time, the failed module can be easily removed and replaced while the controller is online without interrupting the process.
