摘　　要：GP触摸屏具有强大的图形功能和数据处理功能,广泛用于各类控制系统中,为使GP触摸屏能广泛应用于各种智能系统中,通过标准串行接口组成灵活的人机界面。GP触摸屏有多种通信方式,与PLC的直接通信,基于Memorylink通讯协议的通信,以及扩展串口通信。给出扩展串口通信详尽的解决方案,触摸屏的具体设置,并提供了相应的D脚本程序。该方法稳定可靠,为开发者采用GP触摸屏与带标准串口的智能设备之间的通信连接提供了参考。GP touch screen has a powerful graphics capabilities and data processing functions, which is widely used in all kinds of control systems,to make the GP touch screen can be widely used in a variety of intelligent system, a flexible man - machine interface is consisted through a standard serial interface. GP touch screen has several means of communication,directly communicates with the PLC,bases on memory link communication protocol and expansion of serial communication. A detailed solution of expansion of serial communication for touch- screen specific settings is given, and the corresponding D script is provided. This method is stable and reliable, provides a reference for developers to use connection between GP touch screen and intelligent equipments with a standard serial interface.
