一、摘要 PLC是一种专门在工业环境下应用而设计的数字运算操作的电子装置。
它采用可以编制程序的存储器,用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作的指令,并能通过数字式或模拟式的输入和输出,控制各种类型的机械或生产过程。PLC及其有关的外围设备都应按照易于与工业控制系统形成一个整体,易于扩展其功能的原则而设计。在工业生产的各个领域,机械加工企业为了提高生产效率,采用机械化流水作业的方式,对不同类型的零件分别组成的自动生产线。随着产品机型的更新换代,生产线承担的加工对象也随之改变,这就需要改变控制程序,使生产线的机械设备按新的工艺过程运行,而继电接触器控制器系统是采用固定接线,很难适应这个要求。大型自动生产线的控制系统使用的继电器数量很多,随着PLC的应用日益普及,其使用方法简单,便于掌握,且可靠性,抗干扰性很强,自身具有完善的功能.模块化的结构,使其在工业生产线上的应用越来越广泛。
发展趋势:1.向高速度、大容量方向发展
为了提高PLC的处理能力,要求PLC具有的响应速度和更大的存储容量。目前,有的PLC的扫描速度可达0.1ms/k步左右。PLC的扫描速度已成为很重要的一个性能指标。
在存储容量方面,有的PLC可达几十兆字节。为了扩大存储容量,有的公司已使用了磁泡存储器或硬盘。
2.向超大型、超小型两个方向发展
当前中小型PLC比较多,为了适应市场的多种需要,今后PLC要向多品种方向发展,特别是向超大型和超小型两个方向发展。现已有I/O点数达14336点的超大型PLC,其使用32位微处理器,多CPU并行工作和大容量存储器,功能强。
