Set the transmission data to , and while holding it, transmit the data on the communication line A through the transmission (b) j11518. At the same time, the response monitoring timer 15 is activated. Then, the communication control device 1 of the receiving station transmits the data sent from the transmitting station onto the communication line A to the receiving station 1.
6 and sends it to the reception control section 17. At that time, there is a means to determine the reception status! 1 collects uke (/f) from the control unit 17 and discriminates it.

In order to turn on only the signal line a, the receiving bark mode distinguishing means 11 activates the normal response means 12 via the AND gate 21, and a normal response is returned to the transmitting station 31 via the transmitting circuit 18. . The communication control equipment &l of the transmitting station detects a normal response in the response detection circuit 20 via the reception circuit 16 and resets the response monitoring timer 15.

Start 3. After a certain period of time has elapsed, when the response waiting timer 13 reaches 9, the signal line C is turned ON, and the abnormal response means 14 is activated via the OR gate 23 and AND gate 21, and the abnormal response is sent to the transmitting station through the transmitting circuit 18. will be returned to. The communication control device 1 of the transmitting station detects that the response is an abnormal response in the response detection circuit 20 via the reception circuit 16, resets the response monitoring timer 15, and at the same time activates the transmission buffer 19 via the signal line f. call and retry sending. That is, since the abnormal response is returned within a certain period of time 61, there is a high probability that the abnormal state will be resolved and the transmitting station will succeed in retrying transmission in response to the abnormal response.

なっても必ず失敗するからである。Further, when it is determined that the abnormal state is a temporary abnormal state that does not last as shown in Figure @4, the receiving state determining means 11 turns on only the signal 41d, so the abnormal state responding means 14 through the OR gate 23 and the AND gate 22 is activated directly, transmitting circuit 1
The communication control device l of the transmitting station, which immediately returns an abnormal response to the transmitting station via the receiving circuit 16, sends the response 7i,
The detection circuit 20 detects that it is an abnormal response, and
At the same time as resetting each supervision timer 15 (&
This activates the transmission buffer 19 and retries the transmission. Since it is an instantaneous abnormality that does not last, the transmitting station's retry of transmission is sure to succeed.1 In addition, if it is determined that the abnormality is permanent as shown in Figure 5, only the signal i1e is turned ON. Therefore, both the normal response means 12 and the abnormal response means 14 are connected to the AND gate 21,
Since activation is inhibited by the AND gate 22, no response is returned. In the communication control device 1 of the transmitting station, if the timer value of the response monitoring timer 15 is set to a value larger than the timer value of the response waiting timer 13, it is possible to determine whether the response is caused by an abnormality that lasts forever. Only when no response is returned, the response monitoring timer 15 times out. When the response monitoring timer 15 times out, the signal lid g
From K, the transmission buffer 19 is cleared and transmission retry processing is not performed. This is because the communication control device of the receiving station is in an abnormal state that lasts forever, so even if the transmission is retried, it will always fail.
