2. The monitoring and control device of claim 1, wherein the control unit includes a display interruption unit for turning off screen display of the display unit if the operation input unit is not operated for a predetermined time, a display resumption unit for resuming the screen display of the display unit if the operation input unit is re-operated while the screen display is turned off by the display interruption unit, and a page determination unit for determining one of the operation pages to be first displayed on the display unit when the screen display is resumed by the display resumption unit.

3. The monitoring and control device of claim 2, further including a storage unit and wherein the page determination unit causes the storage unit to store, as a latest display page, the operation page displayed on the display unit immediately before the screen display is turned off by the display interruption unit, the latest display page being used as the operation page to be first displayed on the display unit when the screen display is resumed by the display resumption unit.

4. The monitoring and control device of claim 2, further including a storage unit and wherein the page determination unit causes the storage unit to store, as a registered page, one of the operation pages pre-selected by the user'"'"'s operation, the registered page being used as the operation page to be first displayed on the display unit when the screen display is resumed by the display resumption unit.

5. A monitoring and control device for use in a remote monitoring and control system to monitor and control loads by communications, comprising:

a display unit provided with a screen for displaying a plurality of operation buttons mated with the loads;

an operation input unit operable by a user, the operation input unit including a touch switch panel superimposed on the screen of the display unit; and

a control unit for performing display control of the display unit and load control in response to the operation of the operation input unit so that, if a user touches one of the operation buttons displayed on the display unit, the load corresponding to the touched operation button is controlled;

a clock unit for keeping apprised of a current clock time; and

a storage unit that stores different data,

wherein the control unit includes a display control unit for causing the display unit to display one operation page selected from a plurality of operation pages containing different combinations of operation buttons, a page changeover unit for changing over the operation page displayed on the display unit in response to a user'"'"'s operation, a display interruption unit for turning off screen display of the display unit if the operation of the operation input unit is not detected for a predetermined time, a display resumption unit for resuming the screen display of the display unit if the operation input unit is re-operated while the screen display is turned off by the display interruption unit, and a page determination unit for determining one of the operation pages to be first displayed on the display unit when the screen display is resumed by the display resumption unit,

wherein the storage unit stores the operation pages in a mating relationship with different time zones and the page determination unit causes the display unit to initially display, at the time of resuming the screen display, one of the operation pages corresponding to one of the time zones to which the current clock time indicated by the clock unit belongs.

6. The monitoring and control device of claim 5, wherein the time zones are defined within a day.

7. The monitoring and control device of claim 5, wherein the time zones are defined day-by-day in a one-week cycle.

8. A monitoring and control device for use in a remote monitoring and control system that includes an operation terminal provided with one or more switches each having a specific address and designed to deliver a transmission signal containing the address to a signal line in response to the operation of the switches, and a control terminal responsive to the transmission signal for controlling a load corresponding to the operated switch, the monitoring and control device comprising:

an operation input unit provided with one or more switches;

an address memory that stores the address of each of the switches; and

a control unit operable in two active modes including an operation mode in which a transmission signal containing the address is delivered to the signal line in response to at least the operation of the switches and an address-setting mode in which the address to be stored in the address memory is set,

wherein the control unit includes an operation checkup unit for starting an operation checkup mode in which the address-setting mode is stopped as a specified operation is made by the operation input unit during the address-setting mode and in which a transmission signal containing a provisional address composed of the address under setting operation is delivered to the signal line, the control unit being designed to resume the address-setting mode if the operation checkup mode comes to an end.

9. The monitoring and control device of claim 8, further including a state display unit for displaying an operation state of the load mated with each of the switches, while the control unit is in one of the operation mode and the operation checkup mode.

10. The monitoring and control device of claim 8, wherein the operation input unit includes a touch panel display including a display unit for displaying letters and figures in color and a touch switch panel superimposed on a screen of the display unit and touch-operated by a user, the areas of the touch switch panel defined by operation buttons displayed on the screen of the display unit being used as the switches, the control unit being operable in a display color setting mode in which the display colors of the operation buttons displayed on the display unit are set on a switch-by-switch basis.

11. An operation terminal for use in a remote monitoring and control system that includes an operation terminal provided with a plurality of switches each having a specific address, a control terminal connected to a plurality of loads each having a specific address, and a transmission control device connected to a signal line to which the operation terminal and the control terminal are connected in a branched manner, the transmission control device being designed to generate a control data for controlling one of the loads, in response to a monitoring data sent from the operation terminal when one of the switches is operated, and to transmit the control data to the control terminal connected the load having a mating relationship with the operated switch, the transmission control device being designed to, upon receiving an interrupt signal from the operation terminal through the signal line, search for the address of the operation terminal as a source of the interrupt signal, the operation terminal being designed to return a transmission signal containing the address thereof to the transmission control device in response to the address-searching operation of the transmission control device, the operation terminal comprising:

a transmission unit for transmitting the transmission signal and the interrupt signal through the signal line;

an operation input reception unit provided with a plurality of switches and designed to receive an operation input of each of the switches;

a storage unit that stores the address; and

a control unit for generating a monitoring data in response to the operation input received by the operation input reception unit and for causing the transmission unit to transmit a transmission signal containing the monitoring data,

wherein the storage unit is designed to store a specific changeover address having a mating relationship with a switch of an additional operation terminal,

wherein the control unit is designed to selectively change over a permission state in which the operation input received by the operation input reception unit is validated and an inhibition state in which the operation input is nullified, to perform generation of the monitoring data in response to the operation input and transmission of the transmission signal containing the monitoring data when in the permission state, to generate no monitoring data in response to the operation input when in the inhibition state, and to change over the permission state and the inhibition state in response to a control data sent from the transmission control device when the switch of the additional operation terminal having the changeover address is operated.

12. The operation terminal of claim 11, wherein the control unit is designed to nullify only the operation input corresponding to one or more switches pre-selected from a plurality of switches.
