modbus tcp protocol

1.Modbus Introduction-From WikipediaModbus is a serial communication protocol, which was modicon in 1979 for the use of Programmable logic controllers (PLCs). Modbus is the industry standard for communication protocols in the industrial sector and is now a fairly common connection between industrial electronic devices. The main reasons for the wider use of

Since 2002 began to contact the Modbus agreement, in the future in the PLC, DOS, Windows,. Net Micro framework, such as the use of the Protocol, in my previous blog to write a detailed record of this experience, interested friends can look at the " My Modbus slave/client development process (RTU/ASCII/TCP). The

Single-chip microcomputer and (serial screen) touch screen communication based on Modbus Protocol (graphic)Introduction: Touch screen can be intuitive, vivid display of operating parameters and operating state, and through the touch screen screen can directly modify the system operating parameters, human-machine interaction is good. Touch screen and single-chip communication, the need for a single-chip micr

Modbus communication protocol and Programming Modbus communication protocols are divided into RTU and ASCII protocols. Many of our instruments use Modbus RTU communication protocols, such: ch2000 intelligent power monitor, ch2000m power parameter acquisition module, inspection table, digital display table,

Because of the need for work, a simple study of the Modbus Agreement, the university would like to learn automation, the result is not, study also calculate a little to make up the pity. 1.
