Abstract

PURPOSE:In a device that one key station performs the distant supervisory control on plural receiving stations, rapidly to inform the state of all receiving stations to a key station by a poling method of repeating the communication between a key statin and controlled receivig stations and between a key station and the other receiving stations out of the controlled receiving stations reciprocally.
