Abstract

PURPOSE:To restrain the influence dependent upon the fault of the communication line to a minumum, by inserting prescribed repeaters in proper positions of the signal line and disconnecting and separating the signal line when the transmission signal from the master machine is broken. CONSTITUTION:Repeaters B... are inserted to signal line 2 from master machine 1. When the transmission signal from the master machine is broken due to disconnection short-circuit, etc., of the signal line, this repeater disconnects and separates the signal line of the master machine side and the signal line of the terminal side from each other; and when the signal is input, the repeater restores disconnection and separation. Consequently, since the signal line of the master machine side from the repeater which is nearer to the master machine than the faulty position of the signal line is not faulty, normal remote control can be performed for terminals connected to these signal lines. Thus, the influence dependent upon the fault of the signal line such as short-circuit can be restrained to a minimum.
