随着计算机网络的发展,可编程控制器(PLC)作为一种新型数字运算操作的电子系统,利用自动化控制网络的国际通用网络,在工业及工业以外其他领域之中发挥越来越大的作用。介于其抗干扰能力强,功能完善,易改造,低耗能等优点而得到广泛应用。因此,PLC设备的维修技术也有其自身特点。 With the development of computer networks, programmable logic controllers (PLCs), as a new type of digital operation electronic system, utilize an international network of automation control networks to play an increasingly important role in other fields besides industry and industry . Between its strong anti-interference ability, functional, easy to transform, low energy consumption and other advantages have been widely used. Therefore, PLC equipment maintenance technology also has its own characteristics.
