<P>PROBLEM TO BE SOLVED: To allot a highly reliable control right and to reduce a burden such as change of definition data in increase and decrease of monitoring control systems when monitoring control is performed from each of a plurality of computers. <P>SOLUTION: There is provided a monitoring control method in which a control relay device is arranged 10 between one or more pieces of control object equipment 4a-4n at remote places and the plurality of computers 2a-2n which perform the monitoring control of the pieces of control object equipment 4a-4n and the monitoring control of the pieces of control object equipment 4a-4n is performed from the computers 2a-2n via the control relay device 10. In the monitoring control method, a switching instruction of the control right of the control relay device 10 and state data of the control relay device 10 are transmitted by a telecontrol format determined between the respective computers and the pieces of control object equipment 4a-4n for each of the computers 2a-2n. <P>COPYRIGHT: (C)2011,JPO&INPIT |
