Disclosed herein is a method for controlling a slave device in a system comprising a master device and a plurality of groups of slave devices. The method includes: generating, by the master device, a control message containing group data items each corresponding to the respective groups to transmit the control message to a particular group (S610); transmitting, by a slave device included in the particular group, the control message to a next group (S620); extracting, by the slave device, a group data item from the control message after the transmitting the control message (S630); extracting/writing, by the slave device, data from/onto the group data (S640); and transmitting, by the slave device, the group data to the master device after completing the extracting/writing (S650). |
