Description
一、FOXBORO DCS概述
FOXBORO的DCS（Distributed Control System，分布式控制系统）是一种高度集成、模块化的工业自动化系统，广泛应用于电力、化工、石油、冶金等行业的生产过程控制中。FOXBORO的DCS以其高可靠性、高安全性、易于维护和扩展等特点而受到市场的青睐。
二、FOXBORO DCS产品特点
高可靠性：FOXBORO DCS采用先进的硬件和软件技术，确保系统在各种恶劣环境下都能稳定运行。其硬件设计具有多层次的环境防护能力，无暴露的电子元件，无传统的底板和卡件支架，无大型的集中供电组件，工作温度可高达60度，远超其他DCS供应商的产品。
高安全性：系统具有高度的安全性，通过分散智能实现出错检测和诊断功能。所有组件都有自诊断能力，重要组件可选冗余配置，进一步提高了系统的可用率。FOXBORO的冗余设计原则是“容错”，确保每一次输出都是正确的。
灵活组态：控制组态和所有应用软件的生成可以在普通的PC机上进行，然后直接加载到DCS系统上，无需进行编译或转换。这种灵活的组态能力大大节省了工程成本，并为用户提供了最大的方便。
通讯能力强：FOXBORO DCS采用先进的通讯技术，如“目标管理”和“例外报告”，以降低通讯网络上的负荷。数据是面向对象的，系统的数据库是唯一的，任何数据都可以被系统上的任何一个处理器共享。
易于维护和扩展：系统采用模块化设计，所有出现故障的组件都可以在线更换，不会对系统产生任何扰动。同时，系统支持在线修改控制组态和应用软件，无需停机维护
1.Overview of FOXBORO DCS
FOXBORO’s DCS(Distributed Control System)is a highly integrated and modular industrial automation system,which is widely used in production process control in the power,chemical,petroleum,metallurgy and other industries.FOXBORO’s DCS is favored by the market for its high reliability,high security,easy maintenance and expansion.
2.FOXBORO DCS Product Features
High reliability:FOXBORO DCS adopts advanced hardware and software technologies to ensure that the system can operate stably in various harsh environments.Its hardware design has multi-level environmental protection capabilities,no exposed electronic components,no traditional base plate and card brackets,no large centralized power supply components,and the operating temperature can be as high as 60 degrees,far exceeding the products of other DCS suppliers.
High security:The system has a high degree of security and realizes error detection and diagnosis functions through distributed intelligence.All components have self-diagnosis capabilities,and important components can be configured with optional redundancy,which further improves the availability of the system.FOXBORO’s redundant design principle is”fault tolerance”to ensure that every output is correct.
Flexible configuration:The control configuration and all application software can be generated on an ordinary PC and then directly loaded into the DCS system without compilation or conversion.This flexible configuration capability greatly saves engineering costs and provides users with the greatest convenience.
Strong communication capabilities:FOXBORO DCS uses advanced communication technologies such as”target management”and”exception reporting”to reduce the load on the communication network.The data is object-oriented,the system’s database is unique,and any data can be shared by any processor on the system.
Easy to maintain and expand:The system adopts a modular design,and all faulty components can be replaced online without causing any disturbance to the system.At the same time,the system supports online modification of control configuration and application software without downtime for maintenance
