Abstract

PURPOSE:To omit the operation by the operator at the fault occurrence time by detecting the recovery state of the faulty station via the adjacent station and then informing the state to the monitor station. CONSTITUTION:Now in case station 405 has some fault under the normal state of the data highway and thus put under the cut-off state, monitor station 400 gives the return order to the control part of station 402 and also gives the signal discontinuation order to 405 with the similar order given to the control part of station 404. Thus, atation 402 and 404 transmit the discontinuation data to 405. When station 405 has some fault, output 500 of station 402 and output 501 of station 404 are cut off at station 405. And when 405 is released, input signal 500 and 501 are repeated via 405 to be supplied to 402 and 404 in the form of 502 and 503 respectively.
