Abstract

PURPOSE:To decide the priority for the data collection and thus facilitate the easy understanding for the overall condition of the circuit, by having the comparison at the master station which monitors plural number of slave stations for the number of the transmission request signals which are sent from slave stations when the subject of measurement has some change. CONSTITUTION:In the system which gives the monitor at master station 2 to N groups of slave stations in which M units of slave stations 1-1-1-M are set into one group, station 2 has the polling by sending in sequence the address signals of each slave station via address curves 4-1-4-N. At the slave station, the coincidence is secured between the received slave station address and the self-address. And the change of the measuring subject, if any, is detected by the sensor, and then the voltage level to be applied to data circuits 3-1-3-N is varied to be sent to station 2 in the form of the transmission request signal. Station 2 has the comparison for the potential of circuits 3-1-3-N with every group and then decides the priority for the transmission control of the N units of circuits to then select the circuit of the data collection. In such way, the operating condition can be known at station 2 for the entire circuit region, at the same time ensuring an easy comparison for the abnormal degrees of each circuit.
