Claims

[Scope of utility model registration request]

A signal in which communication paths between predetermined processing units are connected in a circular manner to form respective communication loops, and each communication loop has a data destination address signal, a data signal, and an idling period to form one information signal block. For example, in a multiplex communication system in which information processing terminal stations in each of the processing units exchange information, and the communication loops are connected by a control unit to exchange information between the communication loops, each of the information signal blocks an idling detection circuit that detects the end of an idling period and issues an output signal; a first gate circuit that transmits the data destination address signal every time the information signal block is input; a comparison match determination circuit that compares the data destination address signal and the address code of its own station to determine whether they match; an address signal selection section having a second gate circuit that subsequently outputs a data capture command signal; a data capture section that captures the data signal from the other communication loop based on the output of the second gate circuit; and the second data circuit. Signal transmission between communication loops of a multiplex communication system, characterized in that the control unit is provided with a signal cutoff section that cuts off a signal directly transmitted from the input terminal section to the output terminal section of the control unit based on the output of the control unit.
