Kind Code:
B2
Abstract:
To provide a system in which a plurality of modules are connected in a multi-drop method, and even when a plurality of modules having the same identification information are connected in the system, allow recognition as to in which order the modules are connected.SOLUTION: A communication device 1 is a communication device to which a plurality of communication stations are communicably connected, and the plurality of communication stations each have a connection control unit 53 that controls open-circuit and short-circuit of a network bus 50 between the communication station and one or more plurality of other adjacent communication stations, and an order holding unit 55 that holds order information indicating the order in which the communication station is connected in the communication device 1. The connection control unit 53 is configured to open-circuit and then short-circuit the network bus 50 at the power-on of the communication device 1, and the order information is acquired based on a switching pattern from the open-circuit to the short-circuit and held in the order holding unit 55.SELECTED DRAWING: Figure 7
