triconex 4118 增强型通讯模模块 每通道内部的三重电路都是独立的

4118   增强型通讯模模块

4118sis安全仪表系统tricon控制器，基于TMR结构的容错控制器，容错控制系统可以识别和补偿控制系统元件的故障，并允许在继续完成指定任务的同时，对故障元件进行修复， 不中断过程控制。
4118即Tricon控制系统能够在不影响正常生产的同时修复系统故障。具有以下特点:
411 8高度安全性取决于TMR硬件结构自诊断以及在线维修,
4118高可用性消除误停车,
411 8高维护性-在线更换故障卡件，不必停车,维护操作无需培训。
Tricon三重化结构的特点
1、无单点故障
4118sis安全仪表系统- tricon控制器，采用隔离技术:每通道内部的三重电路都是独立的; 三重沉余的主处理器;每个组件箱内都配备两重冗电源(均分负荷的冗余电源) ;在1/0组件内部，没有共享部件: 通道间完全隔离(能够避免现场仪表因接地带来的问题) ;系统与现场之间隔离(避免因单模块被强电击穿而造成整个系统故障)。

4118sis Safety Instrumented System Tricon Controller is a fault-tolerant controller based on TMR structure. The fault-tolerant control system can identify and compensate for faults in control system components, and allow for repair of faulty components while continuing to complete specified tasks without interrupting process control.
The 4118 Tricon control system can repair system faults without affecting normal production. It has the following characteristics:
411 8 High safety depends on TMR hardware structure self diagnosis and online maintenance,
4118 High availability eliminates false stops,
411 8 High Maintenance - Online replacement of faulty cards without the need for parking and maintenance operations without training.
Characteristics of Tricon Triple Structure
1. No single point of failure
4118sis safety instrument system - Tricon controller, using isolation technology: each channel's internal triple circuit is independent; Triple redundant main processor; Each component box is equipped with two redundant power supplies (redundant power supplies with evenly distributed loads); Within the 1/0 component, there are no shared components: the channels are completely isolated (which can avoid problems caused by grounding of on-site instruments); Isolation between the system and the site (to avoid the entire system failure caused by strong electrical breakdown of a single module).
