PLC is a kind of equipment used for automatic control of industrial production.Generally,it can be used directly in industrial environment without taking any measures.However,despite the above-mentioned high reliability and strong anti-interference ability,when the production environment is too harsh,the electromagnetic interference is particularly strong,or the installation and use are improper,it may cause program errors or calculation errors,resulting in erroneous input and Causes false output,which will cause the equipment to run out of control and malfunction,so that the normal operation of the PLC cannot be guaranteed.To improve the reliability of the PLC control system,on the one hand,the PLC manufacturer is required to improve the anti-interference ability of the equipment;on the other hand,it is required to design,installation,use and maintenance have attracted great attention,and multi-party cooperation can solve the problem and effectively enhance the anti-interference performance of the system.
PLC是一种用于工业生产自动化控制的设备,一般不需要采取什么措施,就可以直接在工业环境中使用。然而,尽管有如上所述的可靠性较高,抗干扰能力较强,但当生产环境过于恶劣,电磁干扰特别强烈,或安装使用不当,就可能造成程序错误或运算错误,从而产生误输入并引起误输出,这将会造成设备的失控和误动作,从而不能保证PLC的正常运行,要提高PLC控制系统可靠性,一方面要求PLC生产厂家提高设备的抗干扰能力;另一方面,要求设计、安装和使用维护中引起高度重视,多方配合才能完善解决问题,有效地增强系统的抗干扰性能
