摘　　要：本文提出了在DSP器件上实现Modbus协议,并在此基础上与GP触摸屏通讯。这不仅扩展了GP触摸屏可连接器件的范围,而且对开发者采用GP触摸屏作为带串口的智能设备的上位机和人机界面(HMI)提供了参考。In this paper the method of implementing Modbus protocol by using DSP devices and communicating with GP panel is presented.This method not only extends the area of devices connected to GP panel,but also gives some reference to the developers who use GP panel as HMI and the upper unit which connects the intelligence devices through the serial port.

关 键 词：MODBUS协议 DSP器件 GP触摸屏 通讯 人机界面 程序设计
