Zusammenfassung:	PURPOSE:To efficiently perform addition to connection, change and deletion for transmission node, by providing a node number for each transmission node and transmitting data with only the node of transmission node managing table. CONSTITUTION:At data reception, reception is made for the transmission when the transmission data is only for the node of itself. The node always observes the flow of data on a transmission cable, only the data coincident with a node address 15 of itself is received to a reception buffer 22 for processing. On the other hand, at transmission, after the address 15 is set to a transmitted node number area 51 in a transmission buffer 21, transmission processing is made. Further, in the transmission control section, accessing is made to the node of transmission node managing table set from a middle sized computer only allowing to avoid accessing to nonconnection node. Thus, without decreasing the transmission efficiency, the transmission node can be added to connection, changed and deleted for the node unit.
