<p>PURPOSE:To reduce the scale of data processing and to reduce a reception disable state due to unprocessed reception data at a master station. CONSTITUTION:A master station 1 sends a program and a data to slave stations (1)2, (2)3,... (N)4 connected to the station 1 by a communication line L. The slave stations (1)2, (2)3,... (N)4 form a ring network based on the down-loaded data. The slave stations (1)2, (2)3,... (N)4 start monitoring the state of equipments between adjacent slave stations (slave stations (1)2, (2)3,... (N)4) based on the down-loaded data. When a fault is detected between the adjacent slave stations (1)2, (2)3,... (N)4, the slave stations (1)2, (2)3,... (N)4 detecting the fault inform the fault state of the equipments to the master station 1.</p> |
