Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a same group changing method in the same device system. In recent years, simplification of computer systems has been demanded. In the device definition function of connection management, the device systems are grouped, but if the same device system and the same group are used, only "the same name exists" is displayed. In order to make the device definition function efficient, it is necessary to change the group automatically.

[0002]

2. Description of the Related Art Conventionally, a plurality of device systems (display, server, remote window, printer, etc.) are grouped and connected to a central processing unit. For example,
What is displayed on the display is output to the printer of the group corresponding to the display.

In the device definition function of connection management of a plurality of device systems with respect to the central processing unit, if the devices are in the same device system and in the same group, an error occurs and "the same name exists" is displayed.

[0004]

In such a conventional device definition function of connection management, if the same device system and the same group are used, it is simply displayed that the same name exists. There is a problem that it takes time and effort to make a correction, and the performance of the device cannot be improved.

The present invention has been made in view of such conventional problems, and an object thereof is to improve the performance of the apparatus by automatically changing the group.

[0006]

FIG. 1 illustrates the principle of the present invention. In FIG. 1, (a) is a step of setting a flag for identifying a device system on a table, (b) is a step of checking duplication of groups of the same device system, and (c) is the same device system when the groups are the same. (D) is a step of automatically changing the group name when the same, and (e) is a step of displaying the change.

[0007]

According to the present invention, a flag for identifying a device system is set on the table, a duplication check of groups of the same device system is performed, and it is checked whether the device systems are the same. , The group name is automatically changed and the change is displayed.

Therefore, unlike the prior art, it is not necessary to make a group correction, and the performance of the device can be improved.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 2 to 9 are views showing an embodiment of the present invention.
In FIG. 2, reference numeral 1 denotes a central processing unit, and a plurality of device systems 2 and 3 are grouped and connected to the central processing unit 1.

The device systems 2 and 3 are composed of, for example, servers 4,5, displays 6 and 7, remote windows 8 and 9, printers 10 and 11, and the like. Another printer 12 or the like is connected to the central processing unit 1. A memory 13 is provided in the central processing unit 1, and the group changing program 14 of the present invention is stored in the memory 13.

Further, in the memory 13, a table 15 for identifying the device systems 2 and 3 and check addresses 16 and 17 for performing a group check are respectively provided. As shown in FIG. 3, the table 15 has bytes for the number of device descriptions (= n), and is initially in the off state. The table 15 is turned on according to the device definition example of FIG. 4 or 5. For example, in FIG. 4, since A is a DSP (display), the first bit is turned on (0100
0000). Since B is an SVR (server), the second bit is turned on (0010000). C is RWD
Since it is a (remote window), the third bit is turned on (00010000). Since D is a DSP (display), the first bit is turned on as in A (01000000).

As shown in FIG. 6, the check addresses 16 and 17 are for performing a group check. The check address 16 is the group name of the checking side, and the check address 17 is the group name of the checked side. Put in. Each check address 16 and 17 contains information about the (n) th device description name. Next, the operation will be described.

FIG. 7 is a flowchart of the group changing process. In FIG. 7, first, in step S1, a flag for identifying the device systems 2 and 3 is set (see FIG. 3). For example, A (DSP) is 01,000,000, B (SVR) is 00100000, C (RWD) is 00010000,
D (DSP) is set to 01,000,000.

Next, in step S2, the number of device descriptions (= n)
It is determined whether or not the process of (3) is completed, and when it is completed, the flowchart is terminated. If not, the process proceeds to step S3. In step S3, it is determined whether or not the groups have the same name. First, in FIG. 6, 1 (G
1 and FIG. 4 will be described as an example. ) Is entered, and 2 (G1) is entered in the check address 17. Next, the check address 16 remains unchanged (G1), and the check address 16 contains 3 (G1). When the check address 17 reaches n, 2 (G1) is entered in the check address 16. Similarly, when the check address 17 reaches n, 3 (G1) is entered in the check address 16, and so on ... Until n is entered in the check address 16. If the group names are the same, the process proceeds to step S4 while holding the check address 16 and the check address 17.

In step S4, it is determined whether the device systems 2 and 3 are the same. For example, as shown in FIG.
It processes the R instruction. That is, if two numbers are the same, 0 is set, and if they are not the same number, 1 is set. When the device systems 2 and 3 having the same group name are processed by the EOR instruction and all 8 bits are 0, step S5
If it is 1, the process returns to step S2.

For example, as shown in the device definition example of FIG.
When the SVR of B and the SVR of C are in the same group, the group is changed and a change flag is set in step S5.
That is, the SVR G1 of C is, for example, G100000.
Change to 1. Then, in step S6, the display after the change is displayed on the displays 6 and 7 as shown in FIG. In this way, in the case of the same device system and the same group,
Since it is not necessary to modify the group and the group is automatically changed, the performance of the device can be improved.

[0017]

As described above, according to the present invention, it is determined that the same device system belongs to the same group,
Since the group is changed automatically, the performance of the device can be improved.
