随着工业控制技术的发展,PLC控制系统被我国广泛应用于工业经济中。PLC控制系统的正常运行直接关系着工业生产的稳定和高效。通常情况下,PLC控制系统的稳定性和可靠性较高,出现故障几率低,但针对PLC控制系统在运行中的偶有故障,务必引起工业生产人员的重视。本文将从PLC控制系统及其模型结构分析出发,针对常见的集中故障类型,就如何维护处理PLC控制系统各类故障给出相应对策建议。
With the development of industrial control technology, PLC control system is widely used in China’s industrial economy. The normal operation of PLC control system is directly related to the stability and efficiency of industrial production. Under normal circumstances, the stability and reliability of the PLC control system is high, and the probability of failure is low. However, for occasional faults in the operation of the PLC control system, attention must be paid to the industrial production personnel. This article will start from the PLC control system and its model structure analysis, for the common type of centralized fault, on how to maintain and deal with various types of PLC control system fault countermeasures and suggestions.
