发展回顾
上世纪60年代末PLC产生于美国马萨诸塞州,MODICON084是世界上第一种投进生产的PLC。PLC崛起于70年代,首先在汽车流水线上大量应用。80年代PLC走向成熟,全面采用微电子处理器技术,得到大量推广应用,年销售始终以高于20%的增长率上升,奠定了其在产业控制中不可动摇的地位。90年代,随着工控编程语言IEC61131-3的正式颁布,PLC开始了它的第三个发展时期,在技术上取得新的突破。PLC在系统结构上,从传统的单机向多CPU和分布式及远程控制系统发展;在编程语言上,图形化和文本化语言的多样性,创造了更具表达控制要求、通讯能力和文字处理的编程环境;从应用角度看,除了继续发展机械加工自动生产线的控制系统外,更发展了以PLC为基础的DCS系统、监控和数据采集系统(SCADA)、柔性制造系统(FMS)、安全连锁保护系统(ESD)等,全方位地进步了PLC的应用范围和水平。
21世纪PLC技术发展的几个特点
1、适应市场需要,加强PLC通讯联网的信息处理能力
在信息时代的今天,几乎所有PLC制造商都留意到了加强PLC通讯联网的信息处理能力这一点。小型PLC都有通讯接口,中、大型PLC都有专门的通讯模块。随着计算机网络技术的飞速发展,PLC的通讯联网能使其与PC和其它智能控制设备很方便地交换信息,实现分散控制和集中治理。也就是说,用户需要PLC与PC更好地融合,通过PLC在软技术上协助改善被控过程的生产性能,在PLC这一级就可以加强信息处理能力。例如,CONTEC与日本三菱电机公司(以下简称为三菱电机)合作,推出专门插在小Q系列PLC的机架上的PC机模块,该模块实际上就是一台可在工厂现场环境下正常运行,而且可通过PLC的内部总线与PLC的CPU模块交换数据的PC机。其处理芯片采用IntelCeleron400M主频、系统内存128MB、Cache128K、支持外挂显示器,该模块内装WindowsNT4.0或Windows2000。支持的软件有:三菱综合F4软件,包括PLC编程软件GT、FA数据处理软件MX、人机界面画面设计软件GT、运动控制设计编程软件MT等。
