<p>PURPOSE:To transmit a fault of own device and to display assuredly the working state of the device by supplying a command signal given from own data processor or a command signal given from another data processor which receives the clock of a data transmission line and then transmitting the clock after a fixed period of time. CONSTITUTION:A clock signal (a) is produced from a clock generating circuit 1 of a clock transmission circuit and supplied to the input of one side of a logical integration circuit 11 of a transmission clock generating circuit 2. While the output of a monostable multivibrator 12 is supplied to the input of the other side of the circuit 11. The output of the circuit 11 is sent to a transmission circuit from the circuit 2 in the form of a transmission clock signal (d) via a driver 3. A command signal given from an own data processor and a command signal given from another data processor are supplied to the multivibrator 12. Then a clock signal is transmitted from the circuit 2 after a fixed period of time. The state of a fault of the own data processor is transmitted accurately to another data processor connected via a transmission line. Thus the working state of the data processor is displayed assuredly.</p> |
