摘要
通过某机组厂内进行性能测试时,仿真西门子控制系统与3台变频器进行Modbus RTU轮询通信的实例,介绍了Modbus轮询通信方法及特点,分析并解决了参数设置可能导致的通信问题,保证了通信的完整性和可靠性。
This paper introduces the method and characteristics of the Modbus RTU polling communi-cation through the example of emulating the communication between siemens control system and three transducers which belong to some set when doing capability testing in the factory.It analyses and sovles the communiction problems which can be caused by parameter setting to ensure the integrality and relia-bility of the communication.
