基于VB环境下远程I/O模块的上位机程序设计

The Remote I/O Module Host Program Based on VB Environment

为了将智能仪表测量的现场数据上传至计算机,首先分析了一种智能仪表的通信协议,然后通过MSComm控件实现上位机和下位机的串口通信,实现相关参数的设置和数据的发送接收。

In order to upload the field data measured by intelligent instruments to the computer,the article firstly analyzes of a smart meter communication protocol,and then controls the serial communication of host and slave computer with MSComm,so as to implements the relevant parameter settings,sends and receives data.
