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.
