REMOTE SUPERVISORY AND CONTROLLING EQUIPMENT

PURPOSE:To enable simultaneous control from control stations at the remote supervisory and controlling equipment by transmitting control signals simultaneously according to plural transmission words. CONSTITUTION:This device is equipped with transmission address parameter groups 91-9n corresponding to the control numbers of the control signals, all groups 101-10n for a selection complete position parameter 10 storing the transmitting position of a select complete signal corresponding to a transmission address, and all groups 81-8n for a multiple selection detecting flag 8 similarly corresponding to the transmission address. Therefore, the plural control signals can be simultaneously transmitted. Thus, the simultaneous control is enabled from the control stations while keeping the high realiability of the control signals.
