Multi-Master Technology Based on MODBUS

Introduces a multi-master technology based on MODBUS,which divides all the masters in one network into one master-in-charge and several master-in-listening.While the system is powering on,the master-in-charge is generated through the competition among several masters;while the system is running,the master-in-charge is in charge of date collection,and the master-in-listening is listening and storing the data in order to keep the data complete.If the master-in-charge is out of order,the master-in-listening will compete for a new master-in-charge and then continue on the tasks.This technology makes the communication based on MODBUS securer in a multi-master and multi-slave system.
