摘要
介绍利用Visual Basic 6.0开发工具下的MSComm控件实现对变频器的控制,并以C300系列变频器为例,对其内部的通讯协议和数据帧格式进行了说明,同时进行了利用串口收发数据帧的算法伪码描述。
This paper introduces how to realize to control a transducer by MSComm included Visual Basic 6.0 development kit,and taking the C300 series transducers as a example,illuminates its internal communication agreement and data frames format,and provides pseudocode description of the arithmetic of receiving and idspatching data frames by serial port.
