PLC控制系统的电磁兼容性设计

The Electromagnetic Compatibility Design of the Control System of PLC

分析了ＰＬＣ控制系统的内部及外部干扰源，提出了在系统总体设计、电源，感性负载、隔离、接地、屏蔽、系统配线以及软件等方面所采取的抗干扰措施。

In this paper,the internal and external interferencesource of PLC contral system is analysed. And anti interference measures are presented in respects of the system overall design,power supply,inductance load, isolate,ground,shield, transmission line,software and etc.
