应用背景应用于通信系统信号的调制解调实例，通过systemview软件搭建通信系统仿真平台，给出了信号的调制解调过程及波形具体形式，为与通信实际环境相关，采用高斯噪声模拟通信信道。关键技术SystemView主要用于搭建通信系统平台，采用了软件中的相关器件实现信号的调制及发射。采用低通滤波等得到基带信号，然后采用单刀双掷开关等器件完成判决，实现解码。

这是一个vb与s7200PLC自由口通讯的类模块，我自己工程中可以直接使用。它使用的通讯方式是西门子PLC的自由口通讯技术实现。在工程开发中有不错的表现，希望大家提出宝贵的意见。

Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite. -Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485).
