Slave stations are divided into feature groups according to their feature value and a mapping relationship table between the multicast addresses and the feature groups is established. Data request frames from the master station to the slave stations include a destination address which is parsed by all the slave stations, and if the destination address is the same as the multicast address in the mapping relationship table, the slave stations in the feature group associated with the destination address transmit data in response to the master station, the data request being discarded by other slave stations which are not associated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficiently collecting and distributing multicast data","description":"A more efficient method of data collecting using multicast instead of individual slave-by-slave requests for data defines a multicast address through a master station.
