1. A network apparatus comprising a plurality of modules connected in series, wherein
each module of the plurality of modules comprises:
a front-stage input port configured to receive a signal from a corresponding front-stage module;
a front-stage output port configured to output a signal to the corresponding front-stage module;
a rear-stage output port configured to output a signal to a corresponding rear-stage module;
a rear-stage input port configured to receive a signal from the corresponding rear-stage module;
an ID number information holding circuit configured to hold an ID number information of the module;
a first command generation circuit configured to generate a first command instructing notifying of the corresponding rear-stage module of the ID number information;
a first command output circuit configured to output the first command from the rear-stage output port;
a second command generation circuit configured to generate a second command instructing notifying of the corresponding front-stage module of the ID number information and second ID number information of corresponding rear-stage modules;
a second command output circuit configured to output the second command from the front-stage output port; and
an ID number information update circuit configured to set, when the first command is received from the corresponding front-stage module, new ID number information obtained in a calculation by monotonically increasing or decreasing third ID number information of the corresponding front-stage module contained in the received first command as updated ID number information in the ID number information holding circuit, and
each of the plurality of modules connected to the network apparatus outputs the first command and the second command to assign the updated ID number for each of the plurality of modules connected to the network apparatus.
