PURPOSE:To perform simultaneous operations of a plurality of types of various devices in a plurality of substations by previously setting operating order of the various devices in the case of the simultaneous operation, and sequentially transmitting operation requests of the various devices from a host apparatus to terminal units according to the order. CONSTITUTION:Various devices 41-1-4m-n to be executed for simultaneous operations and their operating order are previously set, and stored in an operation object machine information memory means 6 of a host apparatus 3. If simultaneous operations are instructed, an operation request is transmitted from operation request transmitting means 7 to terminal units 21-2m. In this case, all the units to be executed for the simultaneous operations are designated as destinations, and an operation request of the device having a highest operating order is transmitted. Then, when operating request receiving means 91-9m of the units 21-2m receive the request, the devices 43 4m-n are operated by device operation control means 101-10n. Thereafter, after the apparatus 3 receives an operation confirmation, the operation request for the device of next order is transmitted. |
