1. A network system comprising:
a plurality of control devices; and
an information processing device,
wherein each of the plurality of control devices includes a communication control unit that executes communication using EtherNet/IP and a state value management unit that is connected to the communication control unit and manages a state value,
wherein, of the plurality of communication control units, each of a pair of communication control units set to communicate with each other by opening a connection is configured to execute data processing of at least one of reading of a state value stored in the state value management unit connected to the communication control unit and writing of a state value on the state value management unit based on first setting information set for the communication control unit,
wherein each of the pair of communication control units is configured to execute exchange of frame data including the state value with a communication control unit of a communication partner based on second setting information set for the communication control unit and connection information for opening the connection,
wherein the first setting information and the second setting information are individually generated for each of the pair of communication control units in the information processing device and transmitted from the information processing device to each of the pair of communication control units,
wherein, when at least one communication control unit in the pair of communication control units has failed the data processing, the information processing device displays the first setting information of the one communication control unit and the second setting information of the one communication control unit in a comparable manner on a display, and
wherein, when the pair of communication control units have failed the exchange of the frame data, the information processing device displays the second setting information of one communication control unit in the pair of communication control units and the connection information in a comparable manner on the display.
