The Application of Modbus Among the Multi-systems
Lizheng Li · Microcomputer Information · 2009
This paper is designed to protect electrical devices of communication mechanisms, using Modbus message form of information transmission to achieve a multi-system of information exchange,it solved the black box status of the main CPU module and realized the communication between the various modules;adopted with the CRC checkout, it improved the accuracy and reliability of communications,and achieved several ways for the CRC checkout;in the process of debugging it used Modbus debugging software to imitate the main communication process;during the entire procession all the receiving and sending process are transparent and clear, so the problems of various Modules can be discovered easily and then resolved timely, by this means greatly strengthened the coordination between different developers and different CPU, thereby improving the efficiency of the device research.
