组态维护功能

组态维护功能包括逻辑组态、下载修改、运行调试、远程诊断等。

早期，PLC以梯形图为主，DCS以模块功能图为主。经过多年的发展，国际电工委员会通过IEC1131-3标准规定了五种编程语言,目前主流的DCS和PLC都表示符合这个标准，支持其中的几种或全部编程语言。从开发效率和程序可读性来考虑，模块功能图和顺序功能图越来越成为主要的编程方式，梯形逻辑和结构化文本成为了自定义模块的开发工具。大型PLC在组态方式上越来越像DCS，差距在逐渐缩小，而小型PLC仍然以梯形图为主。

DCS经过多年的发展，积累了大量的高级算法模块。例如NETWORK6000+具有的设备级模块，在一个模块中集中完成了面向设备的基本控制和故障报警功能，在网络通讯中也已此模块为单位进行传递，大大提高了软件开发的效率。一个设备极模块相当于0.5K的梯形图逻辑量，PLC要完成同样的功能，就要烦琐得多了。.
