Abstract

PURPOSE: To make the control easy with less hardware, by constituting a bidirectional bus of hierarchical structure consisting of a master bus and a slave bus.
CONSTITUTION: A master device 1 controls the this system entirely and includes a bus controlling circuit 2, and it controls a master bus 3. Bus relay circuits 41W48 are connected to the master bus 3, and the bus relay circuits 41W48 have slave buses 51W58 respectively for the directional control of incoming and outgoing among the master bus 3 and slave buses 51W58. The slave buses 51W58 are connected with every 8 sets of slave devices (611W618)W(681W688), and the slave devices include the interface controlling circuit with the slave buses.
