0003

[Problems to be Solved by the Invention] Conventionally, the operation panel 21 connected to a host device is operated to display the status of the host device on a console (engineering) on an external terminal 25 connected via a communication path.・For example, referencing/updating data in the storage device, referencing/updating registers in the instruction control device, referencing/updating instruction control microprograms, etc. were displayed as a console (console), so external devices displaying the console were displayed as a console. Terminal 2
If the external terminal 25 and the operation panel 21 are located far apart, it is necessary to go back and forth between the external terminal 25 and the operation panel 21, which is extremely time-consuming and difficult to conduct quickly. There was a problem.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to display the stop state of a host device on an external terminal as a console without leaving the external terminal.

[0005]

[Means for Solving the Problems] Means for solving the problems will be explained with reference to FIG. In FIG. 1, a console control microprogram 5 displays its contents on a console when the host device 1 is stopped. The external terminal 9 is a terminal connected to the input/output device 2 of the host device 1.

[0006]

[Operation] As shown in FIG. 1, in response to a console display request from an external terminal 9 connected to the input/output device 2 of the host device 1, the input/output device 2 notifies the console activation signal. The host device 1 is stopped and the console control microprogram 5 is activated in this state. It is displayed as a console on terminal 9.

[0007] Therefore, when displaying data on the stop state of the host device 1 on the external terminal 9 as a console, it is possible to do so without leaving the external terminal 9.

[0008]

Embodiment Next, the structure and operation of an embodiment of the present invention will be explained in detail using FIGS. 1 to 3. In FIG. 1, a host device 1 is an information processing device that is connected to an external terminal 9 via a transmission path and performs various processes. Here, an input/output device 2, a system control section 3, a console control microprogram 5, an operation panel 6
, an instruction control device 7, a storage device 8, and the like.

The input/output device 2 is a workstation or the like, and sends and receives data to and from an external terminal 9 via a transmission path. The system control section 3 performs system control, and in this embodiment starts the console control starting section 4 in response to input of a console starting signal from the operation panel 6 or the input/output device 2. It performs various controls such as

The console control activation section 4 is activated based on a console activation signal, and after stopping the operation of the command control device 7, etc., starts the console control microprogram 5. The console control microprogram 5 displays the contents of the command control device 7, storage device 8, etc. in the host device 1 as a console.

The operation panel 6 is used to perform various inputs such as inputting console display instructions using keys. The command control device 7 is a control device that executes commands. The storage device 8 stores programs and data. The external terminal 9 is an external terminal connected to the input/output device 2 via a transmission path, and in this embodiment, notifies the host device 1 of a console display request, displays the console, etc., and executes microprograms, This is used to investigate problems with macro programs, etc.

The console (engineer console) also: - References/updates data in the storage device 8 - References/updates registers in the instruction control device 7 - References/updates instruction control microprograms - Input/output device 2 It displays data such as microprogram references/updates.

Next, a process for displaying data in the storage device 8 as a console (engineer console) on the external terminal 9 will be specifically explained in accordance with the order shown in the flowchart of FIG. In FIG. 2, S1 performs an engineer console display operation from the operation panel 6.

[0014] In step S2, the engineer console display operation is performed from the external terminal 9. Processing from S3 onwards is performed from both S1 and S2. In S3, the console control activation section 4 in the system control section 3 stops the command control device 7 in operation. This is done by notifying the console control starting unit 4 of a console display operation from the external terminal 9 in FIG. 4 stops the command control device 7 and the like.

At S4, the console control starting section 4 starts and executes the console control microprogram 5. In S5, the console control microprogram 5 activated in S4 acquires data from the command control device 7 and the storage device 8. S6 edits the above results and creates screen data for the engineer console.

[0016] S7 requests the workstation input/output device to transfer the screen data to the external terminal. In S8, the workstation input/output device sends data. In S9, the external terminal 9 displays the transferred data as a console. As described above, by performing a console display operation on the external terminal 9 or performing a console display operation on the operation panel 6, the console control microprogram 5 can be activated while the instruction control device 7, storage device 8, etc. are in a stopped state. The data in the command control device 7 and storage device 8 can be created as screen data and displayed on the external terminal 9 as a console. This makes it possible to display a console for fault investigation on the external terminal 9 by operating it from the external terminal 9 during the development of microprograms and macro programs. There is no need to go to the location.

Next, the operation when referring to the storage device 8 on the console will be described in detail in accordance with the order shown in the flowchart of FIG. In FIG. 3, S11 performs an operation for referencing the storage device 8 using the external terminal 9. In S12, the workstation input/output device 2 notifies the console control microprogram 5 of the above data.

In S13, the console control microprogram 5 analyzes the notification data. In S14, it is determined whether the result analyzed in S13 is a reference to the storage device 8 or not. Since the answer is YES here, the process advances to S15. In S15, the console control microprogram 5 analyzes an arbitrary address in the notification data.

In S16, the console control microprogram 5 acquires data at the arbitrary address analyzed in S15 from the storage device 8. S17 edits the above results and creates screen data for the engineer console. S18 requests the workstation input/output device 2 to transfer the above screen data to the external terminal 9.

In S19, the workstation input/output device 2 sends data. In S20, the external terminal 9 displays the transferred data as a console. As described above, by performing the operation of referring to the storage device 8 on the external terminal 9,
The console control microprogram 5 can create screen data from the data stored in the storage device 8 and display it on the external terminal 9 as a console. This makes it possible to display the contents of the storage device 8 on the external terminal 9 by operating the external terminal 9 in order to investigate a failure when developing a micro program or a macro program.

[0021]

[Effects of the Invention] As explained above, according to the present invention,
In response to a console display request from the external terminal 9, a console activation signal is sent via the input/output device 2, and the console control microprogram 5 is activated while the command control device 7 and the like are stopped. Since the configuration is such that data from the storage device, instruction processing device, etc. is displayed on the console on the external terminal 9 via the input/output device 2, the data in the stopped state of the host device 1 can be displayed on the external terminal 9 as a console. When doing so, it can be displayed without leaving the external terminal 9. As a result, a console display operation can be performed from the external terminal 9 connected to the host device 1 via the transmission path, and the information can be displayed on the external terminal 9, thereby making it possible to investigate a fault quickly and efficiently.
