Note that, in the description of FIG. 2, the internal configuration of the communication processor 40b is the same as the internal configuration of the communication processor 40a, and the description thereof is omitted. However, in FIGS. , The message transmitting and receiving unit 73,
A state change detection / notification unit 74, a communication line control unit 75, and a common signal line control unit 76 will be described.

FIG. 4 uses the configuration diagram shown in FIG.
FIG. 7 is a diagram for explaining a simultaneous reset processing procedure performed at the time of system startup, and in particular, a procedure for transmitting a reset message. In the figure, parts necessary for explanation are mainly shown.

First, when the system is started, for example, the state change detection / notification unit 44 of the communication processor 40a
Detecting that the system has been started up, the line control method determining unit 41 of the control processor 40d sends the event E1
Send "Restart occurrence notification". The event E1 “restart occurrence notification” includes information indicating the transmission source. Any other event described below includes information indicating a transmission source, although the description thereof will be complicated and omitted.

The line control method determining unit 41, which has received the event E1 “restart occurrence notification” together with the sub-event information “simultaneous reset request”, sets the communication processor 40a in the “reset state” in the section D6 of the line control information storage unit 42. "Reset state" in the column of the opposing communication processing device 50.

If "Reset initial state" is set in that column ("Reset initial state" has already been set), the line control method determining unit 41 sets the event E1
The communication processor 40a that has transmitted the "restart occurrence notification"
The state change detection / notification unit 44 sends the event E
2. Send a "resume 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 column of the counter communication processing device 50 of the “reset transmission processor number” in the section D3 of the line control information storage unit 42. Further, the line control method determining unit 41 sets “reset start state” in the column of the counter communication processing device 50 of “reset state” in the section D6 of the line control information storage unit 42.

The state change detection / notification unit 44 which has received the event E2 “resume notification notification response” together with the sub-event information “reset message transmission is present” sends the event E3 “reset message transmission notification” to the message transmitting / receiving unit 43.

The message transmission / reception unit 43 that has received the event E3 “reset message transmission notification” transmits the event E4 “reset message” to the opposite communication processing device 50 via the common signal line 51.

After the line control method determining unit 41 receives the event E1 “restart notification” from the state change detection / notification unit 44 of the communication processor 40a, the line control method determination unit 41 detects the state change of the communication processor 40b. When the event E5 “restart occurrence notification” is sent from the / notification unit 74, the line control method determination unit 41 determines that the communication processing processor 40b has performed 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 (same as the column of the remote communication processing device of the communication processor 40a) is referred to.
If “Reset start state” is set in that field (“Reset start state” is set at this stage), the line control method determining unit 41 transmits event E5 “Restart occurrence notification”. The event E6 “resume notification notification response” is transmitted to the state change detection / notification unit 74 of the communication processor 40b together with the sub-event information “no reset message transmission”.

The state change detection / notification unit 74 that has received the event E6 “resume occurrence notification response” together with the sub-event information “no reset message transmission” sends the event “reset message transmission notification” to the message transmitting / receiving means 73 (not shown). Do not send. This prevents the reset message from being transmitted to the opposing communication processing device a plurality of times when the system starts up.

FIG. 5 uses the configuration diagram shown in FIG.
FIG. 9 is a diagram for explaining a procedure of a simultaneous reset process performed when the system is started, and particularly, a procedure after a reset response message is received. In the figure, parts necessary for explanation are mainly shown.

As shown in FIG. 4, an event E4 “reset message” is sent to the remote communication processing device 50, and the remote communication processing device 50 performs a reset process (described later with reference to FIGS. 6 and 7). After that, the reset response message returns to the communication processing device 40. The operation of the communication processing device 40 after the return of the reset response message 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” transmitted 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 section 73 sends an event E8 “reset response message reception notification” to the line control method determining section 41. The line control method deciding unit 41 sets the “other station accommodation processor N” in the section D5 of the line control information storage unit 42.
With reference to “o”, the number of the communication processor connected to the communication processor 50 facing the communication 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 of the communication line controllers 45 of the communication processors 40a and 40b,
In response to the event E9,
A "communication line reset notification" and an event E10 "communication line reset notification" are transmitted. When all these transmissions are completed, the line control method determination unit 41 sets the column of the remote communication processing device 50 in the “reset state” of the section D6 of the line control information storage unit 42 to “reset completed state”.

The communication line control unit 45, which has received the event E9 "communication line reset notification", transmits all communication lines 52 between the own communication processor 40a and the opposite communication processing unit 50.

2. Read the number of the communication processor connected to the communication processor 50 facing the communication processor 40a that has transmitted the "reset message reception notification". In this case, the communication processors 40a and 40b are recognized.
Then, the recognized communication processor 4 in the “reset processing completion display” of the section D4 of the line control information storage unit 42
The reset processing status columns corresponding to 0a and 40b are turned on.

For each of the communication line control units 45 and 75 of the recognized communication processors 40a and 40b, the line control method determination unit 41 sends an event E13 "communication line reset process notification" and an event E14 "communication". "Line reset processing notification" is transmitted.

The communication line control unit 45 that has received the event E13 “communication line reset processing notification” resets all communication lines 52 between the own communication processing processor 40a and the opposite communication processing device 50. At the same time, the communication line control unit 75 that has received the event E14 “communication line reset processing notification”

As shown in FIG. 8, an event E22 “reset message” is sent to the remote communication processing device 50,
After the reset processing (described above with reference to FIGS. 6 and 7) is performed in the opposite communication processing apparatus 50, a reset response message returns to the communication processing apparatus 40. The operation of the communication processing device 40 after the return of the reset response message 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” transmitted 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.

Message transmitting / receiving section 73 sends event E26 “reset response message reception notification” to line control method determining section 41. The line control method deciding unit 41 sets the “other station accommodation processor N” in the section D5 of the line control information storage unit 42.
o ”, the communication processor 40b that has transmitted the event E26“ reset response message reception notification ”
The number of the communication processor connected to the communication processing device 50 facing the device is read. In this case, the communication processors 40a and 40b are recognized. Each of the communication line controllers 45 of the recognized communication processors 40a and 40b,
In response to the event E2,
7 "Communication line reset notification" and event E28 "communication line reset notification" are transmitted. When all these transmissions are completed, the line control method determination unit 41 sets the column of the remote communication processing device 50 in the “reset state” of the section D6 of the line control information storage unit 42 to “reset completed state”.

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

Thus, the communication processor 40
All communication lines 52 and 53 between the communication processing devices 50a and 40b and the opposing communication processing device 50 are reset at the same time. FIG. 10 is a diagram for explaining the individual reset processing procedure when individually starting up the communication processors in the communication processing device by using the configuration diagram shown in FIG. 2, and in particular, until the reset circuit message is transmitted. It is a figure explaining the procedure of. In the figure, parts necessary for explanation are mainly shown.

FIG. 10 shows a reset processing procedure when individually starting up the communication processors in the communication line reset apparatus 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, the state change detection / notification unit 44 of the communication processor 40a sends an event E29 "restart occurrence notification" to the line control method determination unit 41 of the control processor 40d. .

The line control method determining unit 41 having received the event E29 “restart occurrence notification” refers to the “connection processor information” in the section D2 of the line control information storage unit 42, and transmits the event E29 “restart occurrence notification”. It recognizes whether the number of communication processors connected to the communication processing device 50 facing the communication processor 40a is singular or plural.

If this is a singular number, there is no problem even if the above-mentioned simultaneous reset processing is performed, so the line control method determining unit 41 transmits the event processor E29 “restart occurrence notification” to the communication processor. An event E30 “response of a restart notification” is transmitted to the state change detection / notification unit 44 of 40a. Subsequent procedures are the same as after the transmission of the event E2 “resume occurrence notification response” shown in FIG.

On the other hand, when the number of communication processors connected to the remote communication processing device 50 is plural (the example in FIG. 10 is this case), the line control method determining unit 41 sets the event E29 “restart occurrence notification To the state change detection / notification unit 44 of the communication processor 40a that has transmitted the event E30 "resume occurrence notification response" 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 “resume notification notification response” sends an event E31 “reset circuit message transmission notification” to the message transmission / reception unit 43.

Message transmitting / receiving section 43 having received event E31 “Notification of reset circuit message transmission”
Is event E32 "Reset circuit message"
To the opposing communication processing device 50 via the common signal line 51. Note that the communication processor 40a is specified in the event E32 “Reset circuit message”.

The opposite communication processing device 50 that has received the event E32 “Reset Circuit Message” resets only the entire communication line 52 with the designated communication processor 40a. When this is completed, an event “reset circuit response message” is transmitted to the communication processing device 40.

FIG. 11 is a view for explaining an individual reset processing procedure when individually starting up the communication processors in the communication processing apparatus by using the configuration diagram shown in FIG. 2. In particular, FIG. It is a figure explaining the procedure after receiving a message. In the figure, parts necessary for explanation are mainly shown.

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.

The message transmitting / receiving unit 43 that has received the event E33 “Reset circuit response message” sends an event E34 “communication line reset notification” to the communication line control unit 45. Upon receiving this, the communication line control unit 45 resets all communication lines 52 between the communication processor 40a and the opposite communication processing device 50.

Thus, it is possible to reset only the communication line between a specific communication processor and the opposite communication processing device, not only when there is a single communication processor but also when there are a plurality of communication processors in the communication processing device. It is.
