により接続し優先処理や障害時の制御を行なっている。(b) Prior Art and Problems FIG. 1 is a diagram showing an example of the configuration of a cross-call system. The host device 1.2 constitutes a host device of the control device 5, and each of the lower devices 7, 8 is selected and used individually through the control device 5. The higher-level devices 3 and 4 are higher-level devices of the control device 6, and each selects and uses the lower-level devices 7 and 8t through the control device 6 independently. The system to which the control device 50 belongs and the system to which the control device 6 belongs are common lower-level equipment fili7
．． A cross-call interface 9 is provided between the control devices 5 and 6 to avoid confusion when simultaneously accessing the control devices 5 and 6.
The system is connected to perform priority processing and control in the event of a failure.

５より制御装置６へ発する。If the higher-level device 3 now reserves and deselects the lower-level device 7 using the control device 6t, the higher-level device 4 can use lower-level devices other than the lower-level device 7 via the control device 6. Select 8 and perform various operations. At this time, if the higher-level device 3 abnormally stops, the lower-level device 17 is reserved, so even if the higher-level device 2 attempts to use the lower-level device 7, it is rejected by the control device 6 via the cross-call interface 9. In order to cancel the reservation of the lower-level device 7, it is necessary to disable the selection between the higher-level device 3 or 4 and the control device 6, so a 9 forced disconnection command (hereinafter abbreviated as BR8W) is sent from the control device 5 to the control device 6. emanate.

が断たれることとなる。Conventionally, BR8W is issued to other operating systems, and the selection between the operating control device and the host device is separated, which has a large impact. In this example, the selection between the higher-level device 4 and the control device 6 is disconnected, and the connection between the lower-level device 8 and the higher-level device 4 is severed.
従って現在は人間が介在してＢＲ８Ｗを発する様にして
いるためシステムの自動運行が妨げられる欠点がある。Therefore, at present, the system requires human intervention to emit BR8W, which has the drawback of interfering with automatic operation of the system.

運行を可能とすることにある。(C) Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks. In a cross-call system, when a host device abnormally stops and a BR8W is issued, the control device that receives the BR8, W activates the BR8W. By deciding whether to recognize and execute it, or to judge it as invalid and ignore it, there is no need for the intervention of two people, and the system's

し操作を行なわないようにした本のである。In agreement, rn determines that the higher-level device has stopped abnormally while retaining the selection, and disconnects the selection from the higher-level device. In the case of mismatch, the higher-level device abnormally stops after completing the selection, and it is determined that another higher-level device is in operation, so that the operation for selecting and disconnecting from the higher-level device is not performed.

~9r! 9th r! The same is true. Registers 10 and 11 are installed in the control devices 5 and 6, respectively, for updating and recording the machine number of the lower device 7 or 80 each time the higher-order devices 1, 2, 3, and 4 select the lower-order device 7 or 8. . Assuming that the higher-level device 3 selects and makes a reservation to the lower-level device 71 via the control device 6 and then abnormally stops, the machine number of the lower-level device 7 is recorded in the register 11 of the control device i16. There is. When the higher-level device 1 attempts to select the lower-level device 7, the control device 6 returns a busy message to the control device 5 via the cross-call interface 9 to notify that another thread is reserved. After a certain amount of time or a certain amount of time has elapsed, the host device 1 determines that the host device 3 or 4 has stopped abnormally, and sends a message to the control device 5.

常の動作を行なう。The control device 5 issues BR8W'f: to the control device 6 via the cross call interface st-m. Control device 6 is BR8
When the W is received, the lower device 7 receives the message from the control device 5.
The machine number is compared with the machine number in the register 11. In this case, since the control device 6 is not selected by any of the higher-level devices 4 other than the higher-level device t3, the register 11 retains the machine number of the lower-level device 7, which matches the machine number sent from the control device 5. Therefore, the control device 6 determines that the host device 3 or ri4 has stopped abnormally during selection, and
Let the selection response signal line ft& be the selection response signal line ft&. Upper device 1 is BR
After the 8W operation is completed, the reservation of 7 is erased in the lower unit in the control device 1i6, and the lower unit 7 is selected, and normal operation is performed.

選択し通常の動作を行なう。Next, a case will be described in which the higher-level device 3 reserves the lower-level device 7, cancels the selection with the control device 6, and then abnormally stops. If the upper-level device 4 selects the ninth lower-level device 8 that can use lower-level devices other than the lower-level device 7 via the control device 6, the register 11
The machine number of lower-level device 8 is recorded, and the lower-level device 70 machine number disappears. At this time, when the higher-level device 1 tries to use the lower-level device 7, the higher-level device 3 has reserved the lower-level device 7 and is stopped, so the control device 6 calls the controller 6 via the cross-call interface 9 because it is busy. Returned to 15. When a certain amount or a certain amount of time has elapsed, the host device 3 or 4 issues a BR8W to the control device 5, assuming that the host device 3 or 4 has stopped abnormally, and the control device 5 transmits the BR8W to the control device 6. The control device 6 has a cross-call interface 9 and an incoming command 1
Since it is a 1BR8W, the machine number of the lower unit F17 sent at the same time and the machine number recorded in the register 11 are checked, but they do not match, so the upper unit number is different from the one that is abnormally stopped. It is determined that the BR8W is in operation, and the BR8W is not executed. Upon completion of BR8W, the higher-level device 1 erases the reservation information regarding the lower-level device w7 in the control device 6, selects the lower-level device 7, and performs normal operations.

なくなりシステムの有効運用、自動運用が可能となる。([) As described in detail of the invention, the present invention has a control device that monitors the status of the host device and can execute a forced disconnection command when the host device stops abnormally, regardless of the state of the host device. This eliminates the situation where a forced disconnection command cannot be issued until the operation of another system is completed, or where a forced disconnection command is issued through human intervention, making it possible to effectively and automatically operate the system.
