可编程控制器的常见故障分析与处理

Programmable controller Common Fault Analysis and Treatment

可编程控制器又可称为PLC,它是工业环境中专门设计的数字运作电子操作装置,其带有能够编写程序的主控制器以及存储器,它可以存储并执行指令,同时它能够进行算术运算、计数、定时、逻辑运算以及顺序控制等操作内容,通过模拟式和数字化的输出与输入功能,全方位的控制各个一体化类型的机械设备,并使其在生产过程中发挥其最佳性能。当前我国应用最多的可编程控制器有日本三菱公司、OMRON公司以及松下公司生产的日系可编程控制器、本文笔者仅就松下公司出产的日系FPI系列可编程控制器为例,通过该产品的介绍简单说明可编程控制器的常见故障和故障处理方式,仅供同行业朋友相互参考借鉴。

The programmable controller may be called a PLC,which is the industrial environment specially designed digital operation of electronic operating device with the ability to write the program's main controller and a memory,it can store and execute the command,and it can be arithmetic,counting,timing, logic operation and sequence control operation content through analog and digital input and output function,a full range of control of each integrated types of mechanical equipment,and make the production process play their best performance.China's current most widely programmable controller with Mitsubishi Corporation of Japan,OMRON Corporation and Matsushita produced Japanese programmable controller,this article the author only Panasonic produced Japanese FPI series programmable controller,for example,through the product's introduction a brief description of the programmable controller of the common faults and fault handling, for the same industry friends cross-reference reference.
