Embodiment Construction

[0016] figure 1 It is a diagram showing the basic configuration of the communication system 10 according to the first embodiment of the present invention. The communication system 10 has a short-circuit connector 12, a plurality of (here, four) branch units 16a to 16d connected in series with the short-circuit connector 12 through the same communication line 14 (indicated by double lines), respectively connected to the branch units 16a to 16d A plurality (the same number as branch units) of communication units 18a to 18d. The branch units 16a to 16d respectively have first connectors 20a to 20d, and the branch units 16a to 16d are respectively connected to the communication units 18a to 18d via the first connectors 20a to 20d.

[0017] The branch unit 16a directly downstream of the short-circuit connector 12 has a second connector 22a and a third connector 24a, the branch unit 16a is connected to the short-circuit connector 12 via the second connector 22a, and the branch unit...

Abstract

The invention provides a communication system with automatic setting function for recognizing numbers; when a communication line is connected with a plurality of communication units, the automatic setting function for recognizing numbers can be automatically set for communication units; the communication system (10) a short circuit connector (12), a plurality of branch units (16a-16d) connected in series with the short circuit connector (12) through the communication line (14), and communication units (18a-18d) respectively connected with the branch units (16a-16d). signal lines (26, 28, 30, 32) are respectively related to bit string ID0-ID3 used for generating a single ID set signal, and the signal lines are wired to the first branch unit (16a) through a second connector (22a). in the branch unit (16a), in the inputted bit string ID0-ID3, two preset two bit signal lines (26, 32) are connected with the communication unit (18a) through the first connector (20a).

Description

technical field [0001] The present invention relates to a communication system having a function of automatically setting an identification number for each of a plurality of communication units constituting a network. Background technique [0002] In a communication system in which multiple communication units are connected to the same communication line, it is sometimes required to set an individual identification number (ID) for each communication unit. In such a communication system, there are cases where various types of communication units are connected, and there are cases where a plurality of communication units of the same type are connected. [0003] For example, Japanese Unexamined Patent Publication No. 08-037538 describes a LAN system that manages the entire system by exchanging management information between LAN devices, provides a management data line different from the network data line, and uses this The management data line transmits a signal for assigning ...
