Delphi写的一个比较不错的 OPC DA Server程序,作为开发OPC Server的一个不错参考。OPC 是OLE在工控领域的应用,同一了不同组态软件之间及组态软件与应用程序之间的通讯标准,以前组态软件与应用程序之间的通讯主要是应用DDE技术。-Delphi wrote a quite good OPC DA Server procedures, the development of OPC Server as a good reference. OPC is OLE in the field of industrial applications, the same between different configuration software and configuration software applications and communications between the standard configuration prior to application software and communications between the main technology is the application of DDE.

非常详细的MODBUS标准串行端口是基于TCP。..一本书
非常详细的modbus规范介绍,有串口的也有基于tcp的。。。。一书在手,modebus不用愁。。。。MODBUS标准分为三部分。第一部分(“Modbus协议规范”)描述了MODBUS事物处理。第二部分(“MODBUS报文传输在TCP/IP上的实现指南”)提供了一个有助于开发者实现TCP/IP上的MODBUS应用层的参考信息。第三部分(“MODBUS报文传输在串行链路上的实现指南”)提供了一个有助于开发者实现串行链路上的MODBUS应用层的参考信息。-very detailed Modbus standard, a serial port is based on the tcp. . . . A book in hand, do not have to worry about modebus. . . . MODBUS divided into three parts. The first part ( "Modbus protocol specification") describes the MODBUS handle things. The second part ( "MODBUS Packet Transmission in TCP/IP Implementation Guide"), provides a help developers to implement TCP/IP on the application layer MODBUS reference information. The third part ( "MODBUS Packet Transmission in the serial link achieve Guide"), provides a help developers achieve serial MODBUS link on the application layer of reference information.
