| Abstract: | How to easily and reliably realize the interior data transmission among the modules in the multifunctional microcomputer-based protection system for experiment and training concerns the stability and reliability of the whole system.Therefore,the interior communication of the system is studied in this paper.Based on detailed introduction of Modbus protocol and its message,a method of using Modbus to realize communication in the system is studied.With respect to the data types and data transmission features in the system,the message frames are compressed and the communication mode is improved.The method not only guarantees the stability of the system but also enhances the speed of interior communication. |
