浅谈可编程控制器安装接线注意问题

Discussion Shallowly on the Wiring Problem for Programmable Controller Installing

可编程控制器技术在工业控制中有着广泛应用,合理地安装和接线,对于提高它在控制系统中的应用有着重要作用。可编程控制器是专门为工业生产服务的控制装置,当生产环境过于恶劣,电磁干扰特别强烈,或安装接线不当,都不能保证正常运行。详细论述了PLC在安装接线过程中,要保证正常运行所必须注意的一系列问题,最后给出合理的建议。

The programmable logic controller technology has the widespread application in industry control. Reasonable installing and wiring has the vital role to enhance its application in the control system. The programmable controller is the control device which specially serves for the industrial production. When the production environment is toughly bad,the electromagnetic interference is special intense,or the installation of wiring is improper,all of these can not guarantee the normal operation. This article elaborates in details a series of questions must be paid attention for normal operation during the installing and wiring of PLC. Finally it gives the rea- sonable suggestion.
