Title: COMMUNICATION SYSTEM, COMMUNICATION DEVICE, AND COMMUNICATION METHOD
Abstract:
This communication system includes a first transmission means for transmitting, in each predetermined period, first data that is used in control for manufacturing equipment or production facilities, and a second transmission means for transmitting, in periods in which the first data is not being transmitted, second data that needs to arrive at the transmission destination within a prescribed time period. The second transmission means includes a determination means for determining whether or not it is possible for the second data to arrive at the transmission destination within the prescribed time period on a first transmission path of a network, and a path changing means for changing transmission paths such that at least a portion of the second data is sent to the transmission destination on a second transmission path of the network that differs from the first transmission path when it is determined that it will not be possible for the second data to arrive at the transmission destination within the prescribed time period.
