1. A control system comprising:
a terminal device capable of communicating with one or more machines via a local network; and
a control device capable of communicating with the one or more machines and the terminal device via a wide area network, the control device being configured to control the one or more machines based on operation information transmitted from the terminal device,
the terminal device including first processing circuitry to
acquire, from each of the one or more machines via the local network, a piece of first machine identification data identifying the machine in the local network, and
generate communicable-machine notification information containing one or more pieces of the first machine identification data on, among the one or more machines, one or more machines that are communicable with the terminal device via the local network, and transmit the generated communicable-machine notification information to the control device,
the control device including second processing circuitry to
acquire, from the one or more machines via the wide area network, one or more pieces of the first machine identification data on the one or more machines,
acquire the communicable-machine notification information from the terminal device via the wide area network,
check the acquired one or more pieces of the first machine identification data against the one or more pieces of the first machine identification data contained in the communicable-machine notification information, and specify, among the acquired one or more pieces of the first machine identification data, a piece of the first machine identification data that matches one piece of the one or more pieces of the first machine identification data contained in the communicable-machine notification information, and
generate, based on the specified piece of the first machine identification data, operation authority information containing the piece of the first machine identification data on a machine operable via the terminal device, wherein
the second processing circuitry acquires, in addition to the one or more pieces of the first machine identification data, one or more pieces of second machine identification data different from the first machine identification data, each of the one or more pieces of the second machine identification data identifying a corresponding machine of the one or more machines in the local network, and
the first processing circuitry transmits, to each of the one or more machines, based on the one or more pieces of the second machine identification data, first-machine-ID request information requesting the machine to transmit the piece of the first machine identification data, to acquire the piece of the first machine identification data from each of the one or more machines.
