至对于现场设备维护管理和跨厂的生产管理控制应用，Industrial”系统都能应付自如。作为
Industrial”家族的重要成员，AC800F系统 在技术上充分体现了ABB首创并领导的Industrial”(工业信
息技术)崭新潮流。
系统分为两级:操作管理级和过程控制级。在操作管理级上不仅实现传统的控制系统监控操作功
能(操作和显示，打印，趋势显示和报警)，而且还完成系统硬件诊测及不同系统间数据交换等功
能。过程控制级实现包括复杂控制在内的各种回路调节(各种PID、比值、Simith 等)和高速逻辑控
制、顺序控制以及批量间歇控制功能。
过程控制站内部通讯(控制器与I/0 等各种智能设备或现场仪表间)采用的是国际标准现场总
线。现场控制器支持Profibus等各种现场总线，Profibus 是目前世界上应用最广泛的开放型现场总
线国际标准，分为FMS、DP 及PA三级，DP 通讯速率可高达12Mb。而CAN (DIN/IS011898 标准)总线
最大特点是它的超级坚固性和数据安全性。系统当然也支持Modbus。与智能现场仪表间的通讯则通过
IART协议或现场总线(31. 25Kb的ProfibusPA和FF总线)。
操作管理级和过程控制级之间的系统通讯由Di giNetS网络(工业以太网/IEE802.3标准)实现，
用户可根据应用的实际情况选择通讯传输介质(普通电缆或光纤)和网络拓朴结构。
大众化的PC机和MS_ Wi ndows2000在全世界已被广泛使用于各个领域，成为事实上的标准计算机平
台。Industrial” 系统的操作站0S、工程师站ES及数据网关GS即采用了这一平台，从而确保了系统的
通用性、开放性和易用性，并对将来的技术升级和维护带来很大方便。
系统工程组态非常方便。组态语言基于IE061131 3工业标准，提供了功能块图(FBD)、梯形图
(LD)、指令表(IL)和顺序功能图(SFC)、结构化文本(ST)等图形化组态方式。系统包含约220 多个功
能块的算法库和具有200多个图形符号的基本图库和内含大量3D图符的扩充图库。
系统使用同一套组态工具软件完成过程级、操作级乃至现场总线仪表的组态以及调试，并使用同
一个全局数据库。
系统规模具备很强的伸缩性，单-系统支持1个到最多100 个控制站及100个操作站。每个控制
站最大可支持几千个I/0点，整个系统规模可扩展。系统控制站硬件均为全金属外壳封装，能承受最
严酷的工业环境。设备既可安装于机柜中，也可装于墙上。
