Abstract
A network terminal of the present invention includes: a synchronization information frame receiving section for receiving a synchronization information frame from a master terminal; a network information managing section for maintaining the network by being synchronized with the synchronization information frame; a synchronization information frame missing detection section for detecting the missing of the synchronization information frame from the master terminal; a priority list storing section for storing a priority list which defines a synchronization information frame transmission start time in such a manner as to differentiate synchronization information frame transmission start times between the network terminals; and a synchronization information frame transmission section for, in a case where the network terminal acts as a new master terminal of the network system, periodically outputting a synchronization information frame, from the synchronization information frame transmission start time in accordance with the priority list, synchronization information frame transmitting section starting to output the synchronization information frame after the missing of the synchronization information frame is detected.
