随着 InTouch 软件在监控系统中应用的日益广泛,越来越多的智能设备在监控系统中的应用,随之带来的问题是各个厂商的智能设备的通信规约各不相同。在 Won-derWare 公司已经开发好的 I/O Server 软件中,不能完全包含这些通信规约的应用程序。在实际的工程应用过程中,通过 DDE 通信协议开发的应用程序完全可以解决 InTouch 软件与智能设备的通信问题,本文通过详细的介绍 DDE 通信协议的原理和程序说明,来阐述 DDE 通信协议在 InTouch 和智能设备之间起到的桥梁作用。
With the increasing use of InTouch software in monitoring systems, more and more smart devices are being used in monitoring systems, with the consequent problem that the communication protocols of smart devices of various manufacturers are different. Won-derWare company has developed a good I / O Server software, you can not completely include these communications protocol applications. In the actual engineering application process, the application developed by DDE communication protocol can completely solve the problem of communication between InTouch software and intelligent device. This paper describes the principle and program description of DDE communication protocol in detail to illustrate the DDE communication protocol in InTouch and A bridge between smart devices.
