摘 要
目前PC已广泛应用于冶金、化工、轻工、机械、电力、建筑、交通、运输等各行各业。
随着机电一体化的发展，对不系统的可靠性要求愈来愈高。可编程控制器有控制可靠，体积小，功能强，速度快，组态灵活和可扩展的特点而得到广泛的应用。可编程控制器是20世纪60年代末在继电器控
制系统的基础上开发出来的。最初叫做可编程逻辑控制器，（programmable logic controller）即PLC。
在我国，PC的应用最近几年发展很快。首当先应用一些大中型现代化工厂的引进工程上，如上海宝山钢铁总厂一、二期工程中就使用了PC达857台。武汉钢铁厂和首都钢铁厂等大型钢铁企业也都使用了许多PC。
在老企业旧设备的技术改造上，PC的应用比较广泛，而且已取得了可喜的经济效益。
PC是专为工业控制设计的控制装置，能适应工业现场的恶劣环境，例如：
电源电压：AC220V±15%。
抗振强度：16.7Hz,3mm双振幅（X、Y、Z三个方向各30min）。
工作温度：0～55℃，有的甚至可以是-10～55℃。
存放温度：-20～60℃。
湿度：35～90%RH无凝结。
