• the control display apparatus including a recording means for storing therein screen data, and a transmitting means for transmitting the screen data stored in the recording means in accordance with a request from a terminal apparatus;
• a server apparatus including:
• a server-end communication means for acquiring device data from the control display apparatus, and for transmitting the device data, the device data indicating the state of the device;
• and
• an execution program recording means for storing therein an applet for causing a terminal apparatus to perform an action of inquiring the server-end communication means about the device data corresponding to the screen data transmitted, and an action of displaying the one of the display-use screens on the terminal apparatus in accordance with the device data corresponding to a process instruction word and a response to the inquiring:
• a plurality of terminal apparatuses each including:
• a terminal-end recording means for storing screen data in a format suitable for display processing, the screen data being for the display-use screen and including one or more process instruction words each including one or more reference information referred to for each carry-out event which is generated in advance in order to display in accordance with device data of a predetermined device;
• the screen data is obtained by combining process instruction words including:
• a process inst ction word for displaying, on a predetermined area of one of the display-use screens, a display element corresponding to predetermined device data;
• and a process instruction word for specifying an input operation;
• a display processing means for inquiring the server-end communication means about whether or not the server-end communication means has acquired the device data corresponding to the process instruction word of the screen data stored in the teiiiiinal-end recording means, and for displaying the display-use screen in accordance with the device data corresponding to the process instruction word which is transmitted from the server-end communication means, and
• a terminal-end communication means for communicating with the server-end communication means via a local network so as to receive the inquiry from the display processing means and the device data as a reply for the inquiry.
