Communication method of RS485 communication system

摘要

The present invention relates to a communication method of a communication system connected to the RS485 communication, the master and slave communication object communication If the communication speed of the object is different from that for the purpose to reduce the initialization time for the slave communication object in response to a communication speed by automatically setting the communication speed as compared with the data according to their communication rate of the transmitted data from the master communication object . is ; A communication method of a communication system of the present invention is connected to the RS485 communication for this purpose, and transmitting the data to the slave according to the communication speed on the master; Comparative data transmitted from the master and the data according to the communication speed of the slave to the master confirming a communication speed; And intended to include the step of setting the communication speed of the identified master to slave in the communication speed.
