Abstract
PURPOSE: To perform the failure detection of the terminal unit, by constituting the failure detection mode blocking the data delivery from the terminal unit.
CONSTITUTION: The unit adds the counter 16-2' by one bit to the low rank of the interrupt retrieval counter 16-1 by one bit and it is used as the lock signal 22'. Further, the lock signal 22' is not used at the terminal device 12 but used as the output block signal of the decoder 20 in the control section 7. The count value of the counter 16-1 consists of the failure detection mode A and the interrupt detection mode B. The output 33 of the failure detection flip flop 37' is the failure report signal to the central processing unit 1, which blocks the failure detection by locking the inhibit gate 34 until the failure flip flop clear signal 35 is incoming
