SPIET800模块备件参数说明

工业控制系统（ICS）是一个通用术语，涵盖多种类型的控制系统，包括监控和数据采集（SCADA）系统，分布式控制系统（DCS），和其他较小的控制系统配置，如经常在工业部门和关键基础设施中用到的防滑安装的可编程逻辑控制器（PLC）。ICS通常使用于电力，水利，石油和天然气，化学，运输，制药，纸浆，食品和饮料以及离散制造（例如，汽车，航空和耐用品）和造纸等行业。控制系统对于经常高度重视的美国关键基础设施的运行至关重要互连和相互依赖的系统。重要的是要注意，大约90％的国家的关键基础设施是私人拥有和经营。联邦机构也经营许多的上述工业流程；其他例子包括空中交通管制和材料处理（例如，邮政服务邮件处理）本节提供了SCADA，DCS和PLC系统，包括典型的架构和组件。SCADA／DCS和PLC的概述
SCADA系统是高分布式系统，经常用于控制地理上分散的资产，分散在数千平方公里，其中集中的数据采集和控制至关重要到系统操作。它们用于配水系统，如配水和废水收集系统，油气管道，电网和铁路运输系统。
一个SCADA控制中心长期对现场进行集中监控通信网络，包括监控报警和处理状态数据。基于信息从远程站接收到的，可以将自动化或操作者驱动的监控命令推送到远程站控制设备，通常被称为现场设备。现场设备控制本地诸如打开和关闭阀门和断路器的操作，从传感器系统收集数据，以及监控当地环境的报警条件。8-3NA11



Industrial control system (ICS) is a general term that covers many types of control systems, including supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and other smaller control system configurations, such as skid mounted programmable logic controllers (PLCs), which are often used in industrial sectors and key infrastructure. ICs is commonly used in power, water conservancy, oil and gas, chemistry, transportation, pharmaceuticals, pulp, food and beverage, as well as discrete manufacturing (such as automotive, aerospace and durable goods) and papermaking industries. The control system is an interconnected and interdependent system that is critical to the operation of critical infrastructure in the United States, which is often highly valued. It is important to note that about 90 per cent of countries' critical infrastructure is privately owned and operated. Federal agencies also operate many of the above industrial processes; Other examples include air traffic control and material processing (e.g., postal service mail processing). This section provides SCADA, DCS and PLC systems, including typical architectures and components. Overview of SCADA / DCS and PLC
SCADA system is a highly distributed system, which is often used to control geographically dispersed assets, scattered in thousands of square kilometers, in which centralized data acquisition and control is crucial to system operation. They are used in water distribution systems, such as water distribution and wastewater collection systems, oil and gas pipelines, power grids and railway transportation systems.
A SCADA control center has a long-term centralized monitoring communication network on the site, including monitoring alarms and processing status data. Based on the information received from the remote station, automatic or operator driven monitoring commands can be pushed to the remote station control equipment, which is usually called field equipment. Field devices control local operations such as opening and closing valves and circuit breakers, collect data from sensor systems, and monitor alarm conditions in the local environment. 8-3NA11
