<p>PROBLEM TO BE SOLVED: To transmit a warning notification frame to a plurality of monitoring control devices even at the occurrence of a failure in which firmware is inoperable in a terminal device installed at a user point, and to flexibly cope with even the change of a notification destination, and to transmit detailed information indicating a failure state in the terminal device.SOLUTION: The firmware of the terminal device preliminarily generates a warning notification frame for each notification destination/failure content when the terminal device starts, and stores it in a warning buffer. On the other hand, hardware always monitors a failure in which the firmware becomes inoperable after the device starts, and when the firmware is inoperable, adds failure occurrence time information and in-device detailed information to the warning notification frame stored by the firmware, and sets up frame transmission trigger to transmit the warning notification frame. Also, when notification destination address information is changed, the notification destination address information is rewritten each time under firmware control.</p> |
