摘要
随着近些年我国自动化水平的快速提升,自动化控制技术已经在很多行业得到了应用,对于自动生产控制具有非常重要的作用。在自动控制过程中,PLC是最为常用的控制器,一旦PLC控制系统发生故障就会直接影响到生产的正常进行,严重情况下会造成较大经济损失,所以需要有效提升PLC控制系统的可靠性。本文主要提出利用冗余技术提升PLC控制系统可靠性方面的内容,分别从软硬件等方面分析提升PLC可靠性的途径,希望能够对相关人士有所帮助。
With the rapid improvement of China’s automation level in recent years, automation control technology has been applied in many industries and plays a very important role in automatic production control. In the automatic control process, PLC is the most commonly used controller. Once the PLC control system fails, it will directly affect the normal production, and even in severe cases, it will cause greater economic losses, so it is necessary to effectively improve the reliability of the PLC control system. This article mainly proposes the use of redundancy technology to improve the reliability of the PLC control system, and analyzes the ways to improve the reliability of the PLC from the aspects of software and hardware, hoping to be helpful to the relevant people.
