Abstract: PURPOSE: A method for determining a master machine in a distributed intelligent network system is provided to cope with the fault generation of a master machine without duplicating an operation terminal in a distributed intelligent network system. CONSTITUTION: Slave machines(SUMMER, AUTUMN and WINTER) transmit hello packets to a master machine(SPRING)(700,710,720). However, the master machine cannot send a response message because it has been in a downed state due to the generation of a fault(701,711,721). In this case, the slave machines transmit hello packets to the machine SUMMER according to a master list(730,740). The machine SUMMER, selected as the new master machine according to priority, toggles the master list and makes out a new master list. As the hello packets are received, the new master machine SUMMER transmits a response message to each slave machine with the new master list. If the fault generated in the machine SPRING is recovered, the machine SPRING transmits a hello packet to the master machine SPRING(750). Then the machine SPRING receives a response message and updates the master list(751).
