采用服务器/客户机进行双机通信，通过局域网送至客户计.       在服务器的框图程序中，首先指定网络端口，并用侦听TCP节点建立TCP侦听器，等待客户机的连接请求，这是初始化的过程。   在用TCP节点进行通信时需要在服务器框图程序中指定网络通信端口号，客户机也要指定相同的端口，才能与服务器之间进行正确的通信。端口值由用户任意指定，只要服务器与客户机的端口保持一致即可。     在一次通信连接建立后，就不能更该端口的值了。如过的确需要改变端口的值，

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).

使用Visual Basic 6实现真正实用的多线程串行通讯 事实上使用Visual Basic的ActiveX exe技术可以轻松的实现多线程处理，此技术在串行通讯中很好用，尤其需要一边通讯，一边数据处理方面，如果用timer实现串行通讯，其复杂程度可想而知。这个实例用在PC与PLC通讯以及PC和单片机通讯，都比较实用。 原理先不说了,先举个示例,有兴趣的话大家可以一起讨论
