Abstract

PURPOSE:To simplify a program for display by editing display data into screen format at a remote maintenance center and printing out the data. CONSTITUTION:A service processor 20 which maintains and diagnoses an information processing system 10 executes a write command to display data on a display device 30 at an actual sit. The write command consists of a write command code, display data length, display position, and display data, and the display position is specified with a row and a column number. a remote maintenance processor 60 converts a write command received from the service processor 20 into the write command of the remote-spot display device 70 and executes it to display data on the remote-spot display device 70. Control commands other than the write command are converted by a remote maintenance processor 60 into control commands of the remote-spot display device 70 and then executed similarly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a display system in a remote maintenance center when an information processing system is maintained from a remote location.

Conventional technology If Figure 1 is a sand layer, the conventional remote maintenance system is an information processing system 10. This system 101' (a service processor 20 connected to it, a remote maintenance processor 6° connected to the service processor 20, and a communication line 50)
．． It is comprised of a local display device 3o and a local printing device 40 connected to the service processor 2°, and a remote location display device 70 and a remote printing device 8° connected to the remote maintenance processor f60.

First, we will explain the on-site maintenance diagnosis of the information processing system 0. When the operator inputs a command for maintenance diagnosis from the keyboard of the on-site display device 3o, the command is decoded and executed by the service processor 20. Maintenance diagnosis of the information processing system 10 is performed by outputting the maintenance diagnosis results to the on-site display device 30 and the on-site printing device 40. Next, maintenance diagnosis from a remote location - To explain, a command similar to the command for local maintenance diagnosis is input from panel a of the remote display device 70, and is sent to the service processor 20 via the remote maintenance processor 60 and the communication line 50. By communicating with the information processing system 10, remote maintenance of the information processing system 10 is performed.

Problems to be Solved by the Invention Regarding the display of maintenance diagnosis results, during on-site maintenance, it is possible to simultaneously output to the on-site display device 30 and on-site printing device 40, but during remote maintenance, display data and print data cannot be combined. 4 to send both of them through the at- 4 need 6
9. There is a drawback that the amount of transfer increases and the output performance of the remote location display device 70 and the remote location printing device e80 decreases. To resolve this drawback, is it possible to send only display data onto the line and use a remote maintenance processor? However, since the local printing device 30 under the service processor 20 and the remote location display device r1170 under the remote maintenance processor 60 are generally different, In addition to the display data sent to the device 30, it is also necessary to edit the display data sent to the line so that the data can be obtained correctly during the maintenance process 60, which complicates the display program of the service processor 20. There is a rough drawback. Additionally, because the edited data generally sends out space characters, the amount of data transferred increases, causing a drop in performance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a universal remote maintenance display that ensures that all correct notes are copied.

90 Ways to Solve Problems The display method of the present invention is applied to an information processing system VC-NI, and a service processor that controls maintenance diagnosis of the information processing system.

a remote maintenance processor having a storage unit connected to the Mlci service processor via a communication line and controlling maintenance diagnosis from a remote location by communicating with the service processor via the communication line;

a display device and a printing device connected to the remote maintenance processor;

a screen buffer provided in a storage section of the remote maintenance processor, displays display data received from the service processor on the display device, creates data for printing device output in the screen buffer, and displays the display data received from the service processor on the display device; The present invention is characterized in that the data for outputting the printing device is output from the screen buffer to the printing device in response to a copy command from the processor.

Example The present invention will be explained in detail using the drawings.

Referring to FIG. 2, one embodiment of the present invention includes an information processing system 10, a service processor 20 that is connected to the information processing system 10 and performs maintenance diagnosis of the information processing system 10, and a system that is controlled by the service processor 20. The on-site display device 30 and the on-site printing device 1t4o, the service processor 20 and the remote maintenance processor 6.O connected by the communication line 50, and the remote location display device 70 and the remote location printing device 80 controlled by the remote maintenance processor 60. ,
The screen buffer 90 is secured in a storage section included in the remote maintenance processor 60.

Next, the display method on the local display R30 and the remote location display device 70 will be explained. The display on the local display device 30 is performed by the service processor 20 executing the write command shown in FIG. 3 (al).

The write command is composed of a write command code, display data length, display position, and display data.The display position is specified by a row number and column number, and can be displayed at any position on a 25×80 screen. As a simple example, 1 is shown in Figure 3(b).
-ABC” is displayed from the 0th row and 20th column.The display on the remote location display device 70 is based on the remote location display of the write command shown in FIG. This is done by converting it into a write command for the device 70 and executing it. Control commands other than the write command are similarly converted by the remote maintenance processor 60 into control commands for the remote location display device 70 and executing them.

Next, a method of hard copying display data to the remote printing device 80 according to the present invention will be explained with reference to FIG. FIG. 4 is a flowchart showing a process in the remote maintenance processor 60 for outputting the same control command as the local display device 30 to the remote location display device 70 and the remote location printing device 80.

If the data received from the service processor 20 is a write command, the screen buffer 9
By writing the display data to the position corresponding to 0, data identical to the image displayed on the remote location display device 70 is created, and is converted into a loading command for the remote location display device 70 and executed. This allows the remote location display device 70
Displayed twice. If the received data is a read command, it is executed after being converted into a read command for the remote location display device 70, and an input prompting display is performed, and after the operator finishes inputting from the remote location display value 7170 keyboard, the input data is It is written to the corresponding position in the screen buffer 90. Thereafter, the data is converted into the read data format of the local display device 30 and sent to the service processor 20. Furthermore, if the received data is a command to move the display screen up or down by one line, or a command to erase the entire screen, the screen buffer 90 performs the corresponding processing, and then the remote display device 70 It is converted into a command corresponding to the operation and executed. As described above, the remote maintenance processor 60 always retains the screen displayed on the remote location display device 70 in the screen buffer 90. The service processor 20 communicates with the remote maintenance processor 60 via the communication line 50 upon completion of screen creation, etc.
When a copy command is sent to the remote maintenance processor 60, the content of the screen buffer 90, which has already been created as a screen image by the copy command, is transferred to the remote printing device 18.
Output to 0.

The above explanation is shown below as a simple printing example using FIGS. 5(a) to (C1). Now, as shown in FIG. If there is a display instruction, and then the manual operation of ■ is performed by the read command, if the displayed data is printed sequentially as it is, ■→■→■
→J- in ■ is printed as shown in Figure 5 (bl). Therefore, it does not match the display screen in Figure 5 (al). Therefore, the display data is not printed sequentially and the screen buffer is printed in response to the write command. If a screen image is created in step 90 and printed from the screen buffer 90 in response to a separate copy command from the service processor 20, it will be printed in the order of ■→■→■→■ as shown in FIG. 5(c). A hard copy that matches the display screen shown in Figure (a) can be made.

Effects of the Invention The present invention has the advantage that by editing display data in screen format at a remote maintenance center and then printing it out, it is possible to obtain a notebook that correctly reflects the screen regardless of the display order.
