摘要
结合实际分析了电磁干扰及其对PLC控制系统干扰的机制,指出在工程应用时必须综合考虑控制系统的抗干扰性能,并提出了几种有效的抗干扰措施。
This article analyzes the electromagnetic interference and the mechanism of its interference with the PLC control system according to the practice.it is also pointed out that the anti-interference function of the control system must be considered comprehensively when applied in engineering.Finally a few valid ?interference measures are put forward.
