By expounding the basic principle of Modbus protocol and combining its practical application in traditional ther-mal power,an optimization method for Modbus configuration of communication management machine is proposed.This method uses the FUN number,INF number and other basic parameters to be configurable to improve the versatility of Modbus configuration,so as to adapt to the specialization of Modbus from different manufacturers.In addition,the auto-matic framing technology with reading is used to dynamically adjust the retry mechanism and the message sending interval to improve the communication efficiency between the communication manager and the access device by using the automatic framing technology with the configuration reading and the communication status.After optimization,it can reduce the workload of technicians and improve the four-remote refresh speed of the background monitoring system.
