Description: 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. Platform: |

Description: routines to manage by polling a serial (RS232) node Modbus RTU slave. The microcontroller on which it was implemented is LPC1768. The routine for performing the CRC16 checksum is very small and very fast. MODBUS-SLAVE is complete. VERY INTERESTING. Platform: |

Description: 不借助其它底层Modbus控件,直接操作底层通讯代码,实现Modbus读写“保持寄存器”数据,支持串口通讯、TCP通讯两种方式。代码只作演示,可做进一步封装,也可稍作修改,用于非标准的Modbus通讯。本代码使用了一个第三方控件SPComm,开发测试环境为Delphi7+Win7,我一直想摆脱Modbus控件(MBAXP Modbus Master ActiveX Control
),最近自己开发了这个DEMO,分享给大家。(Without other underlying Modbus controls, the direct operation of the underlying communication code, the realization of Modbus read and write, "keep register" data, support for serial communication, TCP communication two ways. The code is for demonstration only, can be further encapsulated, and can be modified slightly for nonstandard Modbus communications. This code uses a third party control SPComm, development test environment for Delphi7+Win7, I always want to get rid of Modbus control (MBAXP Modbus Master ActiveX Control
) recently developed this DEMO and shared it with you.) Platform: |

Description: MODBUS通讯协议标准详细说明,中文版本。(Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a factory standard communication protocol and is now a commonly available means of connecting industrial electronic devices.
Here is the chinese version.) Platform: |
