摘要
PLC控制系统以其优良的性能和极高的可靠性在工业控制特别是顺序控制过程中得到了广泛的应用。本文以某大型液压设备工程项目为背景,介绍使用S7-300PLC构建控制系统的步骤及其组态软件STEP7的编程调试流程。实际使用结果表明:该PLC系统具有设计简单、编程方便、运行可靠等优点。
PLC control system has been widely applied in industrial control for its excellent performance and high reliability, particularly in the sequential control process. Building steps of S7-300 PLC and programming/debugging process of software STEP7 were introduced with the project background of a large hydraulic equipment. Advantages such as simple design, convenient programming, reliable running and so on were indicated in the actual implementation of the PLC system.
