The state change detection / notification unit 44 detects a state in which resetting is required, such as when the system is started up, when the failure of the common signal line is recovered, when the individual processor is started up, and notifies the line control method determination unit 41. The communication line control unit 45 resets the communication line 52 between the communication processor 40a and the opposite communication processing device 50 according to the reset instruction from the line control method determination unit 41 and the like. The common signal line control unit 46 detects that the failure of the common signal line 51 has been recovered, and notifies the state change detection / notification unit 44.

The operation of the communication line reset device having the above configuration will be described with reference to FIGS. In the description of FIG. 2, the internal configuration of the communication processing processor 40b is the same as the internal configuration of the communication processing processor 40a, and the description thereof is omitted. However, in FIGS. , The message transmitting / receiving unit 73,
A state change detection / notification unit 74, a communication line control unit 75, and a common signal line control unit 76 are included.

FIG. 4 uses the configuration diagram shown in FIG.
It is a figure explaining the processing procedure of simultaneous reset performed at the time of system start-up, and is a figure explaining especially the procedure until a reset message is transmitted. In the figure, the parts necessary for explanation are mainly displayed.

First, at system startup, for example, the state change detection / notification unit 44 of the communication processor 40a
Event E1 is detected in the line control method determination unit 41 of the control processor 40d by detecting that the system is in the startup state.
Send a "restart occurrence notification". The event E1 “restart occurrence notification” includes information indicating the transmission source. The description of each of the other events described below is complicated because the description of each event is complicated, but is omitted, but includes information indicating the transmission source.

Upon receiving the event E1 "restart occurrence notification" together with the sub-event information "simultaneous reset request", the line control method determination unit 41 sets the communication processor 40a in the "reset state" of the section D6 of the line control information storage unit 42. Refer to the “reset state” in the column of the opposite communication processing device 50.

If the "reset initial state" is set in that column (the "reset initial state" has already been set), the line control method determination unit 41 determines that the event E1 has been set.
Communication processor 40a that has transmitted the "restart occurrence notification"
In the status change detection / notification unit 44 of the event E, the event E is sent together with the sub-event information "reset message is transmitted"
2. Send the "restart occurrence notification response". At the same time, the line control method determination unit 41 writes the identification number of the communication processing processor 40a in the field of the opposite communication processing device 50 of the "reset sending processor number" of the section D3 of the line control information storage unit 42. Further, the line control method determination unit 41 sets the “reset start state” in the field of the opposite communication processing device 50 in the “reset state” of the section D6 of the line control information storage unit 42.

The state change detection / notification unit 44, which has received the event E2 "restart occurrence notification response" together with the sub-event information "reset message transmitted", sends the event E3 "reset message transmission notification" to the message transmission / reception unit 43.

Upon receiving the event E3 "reset message transmission notification", the message transmitting / receiving unit 43 transmits the event E4 "reset message" to the opposite communication processing device 50 via the common signal line 51.

Note that the line control method determination unit 41 detects the state change of the communication processor 40b following the event E1 "restart occurrence notice" sent from the state change detection / notification unit 44 of the communication processor 40a. / When the event E5 “restart occurrence notification” is sent from the notification unit 74, the line control method determination unit 41 causes the communication processing processor 40b to perform the opposite communication process in the “reset state” of the section D6 of the line control information storage unit 42. The column of the device 50 (the same as the column of the opposite communication processing device of the communication processor 40a) is referred to.
When the "reset start state" is set in that column (the "reset start state" is set at this stage), the line control method determination unit 41 transmits the event E5 "restart occurrence notification". The event E6 “restart occurrence notification response” is transmitted to the state change detection / notification unit 74 of the communication processing processor 40b together with the sub-event information “no reset message transmission”.

Upon receiving the event E6 "restart occurrence notification response" together with the sub-event information "no reset message transmission", the state change detection / notification unit 74 notifies the message transmission / reception means 73 (not shown) of the event "reset message transmission notification". Is not sent. This prevents the reset message from being transmitted to the opposite communication processing device multiple times when the system is started up.

After that, the reset response message is returned to the communication processing device 40. The operation of the communication processing device 40 after the reset response message is returned will be described.

For example, it is assumed that the message transmitting / receiving unit 73 of the communication processor 40b receives the event E7 "reset response message" sent from the opposite communication processing device 50 via the common signal line 54. The event "reset response message" may be sent to the message transmitting / receiving unit 43 of the communication processor 40a.

The message transmitting / receiving unit 73 sends the event E8 "reset response message reception notification" to the line control method determining unit 41. The line control method determination unit 41 uses the “other station accommodation processor N” of the section D5 of the line control information storage unit 42.
"o", the number of the communication processing processor connected to the communication processing device 50 facing the communication processing processor 40b that has transmitted the event E8 "reset response message reception notification" is read. In this case, the communication processors 40a and 40b are recognized. Each communication line control unit 45 of the communication processing processors 40a and 40b recognized by this,
75, the line control method determination unit 41 determines that the event E9
The "communication line reset notification" and the event E10 "communication line reset notification" are transmitted. When all of these transmissions are completed, the line control method determination unit 41 sets the field of the opposite communication processing device 50 in the “reset state” of the section D6 of the line control information storage unit 42 to the “reset completed state”.

The communication line control unit 45, to which the event E9 "communication line reset notification" is sent, receives all the communication lines 52 between the own communication processing processor 40a and the opposite communication processing device 50.
To reset. At the same time, the communication line control unit 75 to which the event E10 “communication line reset notification” is sent also resets all the communication lines 53 between the own communication processing processor 40b and the opposite communication processing device 50.

After the reset processing (described above with reference to FIGS. 6 and 7) is performed in the opposite communication processing device 50, the reset response message is returned to the communication processing device 40. The operation of the communication processing device 40 after the reset response message is returned will be described.

For example, it is assumed that the message transmitting / receiving unit 73 of the communication processor 40b receives the event E25 "reset response message" sent from the opposite communication processing device 50 via the common signal line 54. The event "reset response message" may be sent to the message transmitting / receiving unit 43 of the communication processor 40a.

The message transmitting / receiving unit 73 sends the event E26 "reset response message reception notice" to the line control method determining unit 41. The line control method determination unit 41 uses the “other station accommodation processor N” of the section D5 of the line control information storage unit 42.
communication processor 40b which has transmitted the event E26 "reset response message reception notification" with reference to "o"
The number of the communication processing processor connected to the communication processing device 50 opposite to is read out. In this case, the communication processors 40a and 40b are recognized. The communication line control units 45 of the recognized communication processors 40a and 40b,
75, the line control method determination unit 41 determines that the event E2
7 "Communication line reset notification" and Event E28 "Communication line reset notification" are transmitted. When all of these transmissions are completed, the line control method determination unit 41 sets the field of the opposite communication processing device 50 in the “reset state” of the section D6 of the line control information storage unit 42 to the “reset completed state”.

Event E27 "Communication line reset notification"
The communication line control unit 45, which has been sent, sends all communication lines 5 between the own communication processing processor 40a and the opposite communication processing device 50.
Reset 2. At the same time, the communication line control unit 75 to which the event E28 “communication line reset notification” is sent also resets all the communication lines 53 between the own communication processing processor 40b and the opposite communication processing device 50.

In this way, the communication processor 40
All the communication lines 52, 53 between the a, 40b and the opposite communication processing device 50 are reset all at once. FIG. 10 is a diagram for explaining the processing procedure of the individual reset when individually starting the communication processing processors in the communication processing apparatus by using the configuration diagram shown in FIG. 2, and particularly until the reset circuit message is transmitted. It is a figure explaining the procedure of. In the figure, the parts necessary for explanation are mainly displayed.

FIG. 10 shows a reset processing procedure at the time of individually starting the communication processing processors in the communication line reset device of the present invention in which the simultaneous reset processing is realized as described above.

For example, when only the communication processor 40a is started up, the state change detection / notification unit 44 of the communication processor 40a sends the event E29 "restart occurrence notification" to the line control method determination unit 41 of the control processor 40d. .

The line control method determination unit 41, which has received the event E29 "restart occurrence notification", refers to the "connected processor information" of the section D2 of the line control information storage unit 42 and transmits the event E29 "restart occurrence notification". It is recognized whether the number of communication processing processors connected to the communication processing device 50 facing the communication processing processor 40a is singular or plural.

If the number is singular, there is no problem even if the above-mentioned simultaneous reset processing is performed, so the line control method determination unit 41 sends the event E29 "restart occurrence notification" to the communication processor. The event E30 "restart occurrence notification response" is transmitted to the state change detection / notification unit 44 of 40a. The subsequent procedure is the same as that after the event E2 “restart occurrence notification response” shown in FIG. 4 is transmitted.

On the other hand, when the number of communication processors connected to the opposite communication processing device 50 is plural (this is the case in the example of FIG. 10), the line control method determination unit 41 notifies the event E29 "restart occurrence notification". To the state change detection / notification unit 44 of the communication processor 40a which has transmitted the message "E30", the event E30 "restart occurrence notification response" is transmitted together with the sub-event information "reset circuit message transmission request".

Event E30 together with sub-event information "reset circuit message transmission request"
The state change detection / notification unit 44 that has received the “restart occurrence notification response” sends the event E31 “reset circuit message transmission notification” to the message transmission / reception unit 43.

The message transmitting / receiving unit 43 which has received the event E31 "reset circuit message transmission notification"
Is event E32 "Reset Circuit Message"
To the opposite communication processing device 50 via the common signal line 51. The communication processor 40a is designated in the event E32 "reset circuit message".

Upon receiving the event E32 "reset circuit message", the opposite communication processing device 50 resets only all communication lines 52 with the designated communication processing processor 40a. When that is completed, the event “reset circuit response message” is transmitted to the communication processing device 40.

FIG. 11 is a diagram for explaining the processing procedure of individual reset when individually starting the communication processing processors in the communication processing apparatus by using the configuration diagram shown in FIG. It is a figure explaining the procedure after receiving a message. In the figure, the parts necessary for explanation are mainly displayed.

The event E33 "reset circuit response message" transmitted from the opposite communication processing device 50 is
It is sent to the message transmitting / receiving unit 43 of the communication processor 40a via the common signal line 51.

Upon receiving the event E33 "reset circuit response message", the message transmitting / receiving unit 43 sends the event E34 "communication line reset notification" to the communication line control unit 45. In response to this, the communication line control unit 45 resets all communication lines 52 between the communication processor 40a and the opposite communication processing device 50.

As a result, it is possible to reset only the communication line between the specific communication processing processor and the opposite communication processing apparatus when there is a single communication processing processor in the communication processing apparatus or when there is a plurality of communication processing processors. Is.
