摘要
Abstract
Through the data collection and analysis method, this paper analyzes the key message format of MPI protocol, which can be used to communicate between upper computer, on-site equipment and CPU supporting the MPI protocol, thus providing an efficient low-cost communication mode. In addition, through analysis of protocol, this paper implements communication between IPC and HMI based on MPI protocol using serial communication.关键词
