摘要
可编程控制继电器以逻辑连接取代传统布线,具有节约安装空间、省时省费用、编程简单、快速调试及集中控制与就地控制等特点,在机器设备、控制系统、楼宇自动化及煤矿机电等领域广泛应用。
Compared to the former method, in relay controlling, PLC uses logic circuit units instead of amount of wire layouts, whose characteristic is saving configuration space, using lesser fixing time and expense, programmed easer, using lesser debugging time and flexible in control mode choosing, which is widely used in the controlling of electrical equipments, controlling systems, construction automation and coal mining electrical equipment＇ s controlling.
