Supervisory unit and supervisory control system provided with the same

A supervisory unit connected via a communication line to a plurality of control units to which object loads are connected, comprising:

• a supervisory inputting section for judging the status of an object load by input signal from said object load;
• a memory section in which the communication address and the corresponding control data with respect to each of said control units to be controlled are stored in advance;
• and
• a communication/control processing section for sending out via the communication line a control request signal given an addition of said address and said control data, when judging the change of the status of the object load into on or off status by the input signal received at said supervisory inputting section or when receiving other control request signals via the communication line.

A supervisory control system, comprising:

• control units to which object loads are connected and said operation display unit is provided which includes:
• a display section for displaying the status of object loads connected to the control units;
• a memory section in which the communication address and the corresponding status data with respect to each of the control units, and a destination address of other display sections, or other supervisory units are stored;
• and a communication/control processing section for comparing said status data received from ech of the control units and said status data stored in said memory section, when receiving said status data from each of the control units having been controlled via the communication line to display the comparison result as the comparison result data on said display section, and for sending out a control request signal given an addition of said destination address of said other display units or other supervisory units to the communication line;
• and
• said supervisory unit having a supervisory inputting section for judging the status of an object load by an input signal from said object load;
• a memory section in which the communication address and the corresponding control data with respect to each of said control units to be controlled are stored in advance;
• and a communications/control processing section for sending out via the communications line a control request signal given an addition of said address and said control data, when judging the change of the status of the object load into on or off status by the input signal received at said supervisory inputting section or when receiving other control request signals via the communications line, connected to each other via the communication line, wherein:
• said operation display unit and/or said supervisory unit send out said control request signal to other operation units or other supervisory units via the communication line, when it/they receives/receive a control request signal via the communication line.

A supervisory control system, comprising:

• a plurality of control units to which object loads re connected;
• and
• said operation display unit having a display section for displaying the status of object loads connected to the control units;
• a memory section in whic the communication address and the corresponding status data with respect to each of the control units, and a destination addresses of other display sections, or other supervisory units are stored;
• and a communications/control processing section for comparing said status data received from each of the control units with said status data stored in said memory section, when receiving said status data from each of the control units having been controlled via the communication line to display the comparison result as the comparison result data on said display section, and for sending out a control request signal given an addition of said destination address of said other display units or other supervisory units to the communication line connected to each other via a communication line, wherein:
• said operation display unit sends out comparison result data to other operation display units connected to the communication line, when it receives the status data of said object load from said control unit via the communication line.

A supervisory control system comprising:

• control units to which object loads are connected;
• and
• an operation display unit having an operation section for controlling said object loads connected to each of said plurality of control units;
• a display section for displaying the status of said object loads connected to said control units;
• a memory section in which the communication address and the corresponding control data with respect to each of said control units are stored in advance;
• and a communication/control processing section for sending out a control request signal given an addition of said communication address and the corresponding control data stored in said memory section to the communication line and for comparing said status data of said object loads received from each of said control units with said corresponding control data stored in said memory section, when receiving said status data from each of said control units having been controlled by said operation display unit via the communication line and for thereafter displaying the comparison result as the comparison result data on said display section, connected to each other via a communication line, wherein:
• said control unit comprises a control section for controlling said object loads;
• a memory section in which a communication address of said control unit are stored in advance;
• a supervisory section for supervising the status of the object loads;
• a communication/control processing section for controlling said object loads when receiving a control signal via the communication line and for detecting the status of object loads having been controlled to send out the status data of said loads given an addition of said communication address stored in said memory section;
• and said operation display unit being changed into a reaction display mode when it sends out a control request single given an addition of the communication address and the corresponding data with respect to said control unit to be controlled by operation of said operation section and thereafter displaying comparison result data obtained from comparison of said status data of said object loads with said corresponding control data.

A supervisory unit connected via a communication line to a plurality of control units to which object loads re connected, comprising:

• a supervisory inputting section for judging the status of an object load by input signal from said object load;
• a memory section in which the destination address for control request signal is stored in advance;
• and
• a communication/processing section for sending out via the communication line a control request signal given an addition of said destination address, when judging the change of said object apparatus into an on or off status by the input signal received at said supervisory inputting section and for invalidating the operation of said operation section when receiving operation inhibit signal via the communication line and for removing said invalidation to permit to send out said control request signal when receiving an operation permission signal.
