摘要
可编程序控制器(PLC)是一种工业用的控制器,由于其结构紧凑、低功耗、高可靠性、易操作、适合顺序控制的特点而被广泛应用。但在工业环境下存在许多干扰源而影响了系统的运行,为了提高系统的抗干扰能力、保障系统可靠的工作必须采取合适的措施抑制干扰。
The Programmable Logic Controller (PLC) is a kind of industrial controller. Due to its main features of compact structure , low power consumption , high reliability ,easy operation, and being suitable for sequence control , it has been widely used in many fields. But in industrial environment there are many interference sources which aeffect the system running. In order to improve the anti-interference ability and secure the system running reliably, suitable steps must be taken to prevent the interference.
