Abstract

PURPOSE:To facilitate the maintenance of a relative control table when a different kind of equipment is added by providing an equipment characteristic information table which holds specifying information on a program module that each kind of equipment requires in addition to characteristic information on each kind of equipment. CONSTITUTION:An equipment generation part 30 generates an equipment description table 36. The equipment characteristic information table 34 contains specifying information 50 on the necessary program module of equipment in addition to conventional equipment characteristic information table 13 and both of those pieces of information are stored as equipment characteristic information in each item of the equipment description table 36. A control program generation part 40 needs not have a conventional module table and scans respective items in the table 36 successively to determine necessary program modules for processing. Consequently, only the equipment characteristic information table 34 is maintained at the time of the addition and alteration of the kind of equipment.

Description

[Detailed Description of the Invention] [Summary] This is a control method for generating a control program for a computer system by combining program modules that depend on the types of devices that make up the system. In a table holding control information corresponding to each model, information specifying a program module required by each model is held together with the control information, for example, in bit-corresponding display. This method facilitates table maintenance for configuring control programs by adding and subtracting devices.

[Industrial application field]

The present invention relates to a control program generation control method when a control program for a computer system is configured by combining program modules depending on the types of devices that configure the system.

When controlling devices such as various workstations and line interfaces that are connected to a computer system using a control program such as firmware, there is a difference between a control section that performs specific control for each device type and a common control section. A widely used method is to create each program module, and when the configuration of a computer system is determined or changed, a control program consisting of program modules necessary for connected devices is generated.

[Conventional technology]

FIG. 3 is a block diagram showing an example of the configuration of a computer system, and the computer 1 can be configured to connect and control various devices 2 such as workstations.

In this case, the computer 1 has the following information in order to control each device 2:
Each device requires control information such as a device name, model of the device, model-specific information, and parameter information to identify each device in the system.

Here, the model-specific information includes, for example, the device type that indicates the classification of the model, and the hardware function details that indicate the details of the functions determined by the device type. This includes the number of dots in character display, whether graph display is possible, etc.

Parameter information is information that specifies the functions of each device that can be specified for each computer system, such as the physical machine number of the device connection location, the Japanese/English language of the output message, This includes specifications such as the size of the file area for logging data sent and received by the device.

The control information is created as a so-called device description table that can be indexed, for example, by device name, and each entry is configured to be control information for each device.

In addition, in order to generate a control program constituting firmware that realizes the control function of each device, for example, a program module prepared corresponding to each device type listed in the device description table is selected, It is necessary to be able to generate a control program by combining these selected modules.

The generation of the device description table, control program, etc. described above can be executed by the computer 1, for example, by the system operator inputting necessary commands from the operator's console 3.

FIG. 4 is a block diagram showing an example of the configuration of the control information generation process.

In processing step 11, the device description generation unit 10 receives command input from the console 3. Using this command, the operator specifies the device model name, device name, parameter information, etc. for each device.

When it is determined in step 12 that the command does not specify termination, in step 13 the model-specific information table 14 is referred to by the model name specified in the command,
Get the model-specific information.

As shown in the figure, the model specific information table 14 includes the model name,
It is configured as a correspondence table with the model-specific information as described above.

In step 15, one item of the device description table is created using the above information, and added to the device description table 16.
Or update the section with the same device name and return to the next command reception process. Note that if the command specifies deletion of the device specified by the device name, the device is deleted from the table.

Each item in the device description table 16 consists of the device name, model name, and parameter information specified by the command, and model-specific information obtained from the model-specific information table 14.

When the operator finishes inputting the command for specifying the required device description, he inputs a command indicating the end. Accordingly, according to the identification in step 12, the processing of the device description generation section 10 is ended and the processing of the control program generation section 20 is started. do.

In step 21, the machine name is read one item at a time from the device description table 16, and in step 22, the designation information II of the program module required for the machine is extracted from the module table 23 according to the model name.

The module table 23 is a correspondence table between the model name and the specification information of the program module required for that model.The specification information is prepared in the system, for example, the first bit is module A, the second bit is module B, etc. All modules are displayed in bit correspondence, and a bit of 1 indicates that the corresponding program module is required.

In step 24, the designation information to be retrieved sequentially is logically summed on an appropriate register, and in step 25, it is determined whether all items in the device description table 16 have been processed. If not, the process returns to step 21.

When all the devices have been processed, the process proceeds to step 26, where all the program modules necessary for this system are specified by the logical sum of all the necessary specification information obtained on the registers, so this information can be manually used. , generate a control program including the specified module.

[Problem that the invention seeks to solve]

According to the conventional method, when a new model of device is added, an entry for the new model name is added to the model-specific information table 14 for update registration, and the new model name is also added to the module table 23. There is a problem in that updating processing is required to add a term, making maintenance of the table complicated.

[Means for solving problems]

FIG. 1 is a block diagram showing the configuration of the present invention, and FIG. 2 is an explanatory diagram of the configuration of the model-specific information table of the present invention.

In the figure, 30 is a device description generation section, 34 is a model-specific information table, 40 is a control program generation section, and 50 is specification information for specifying a program module.

(Function) The device description generation section 30 generates the device description table 36 in the same manner as the conventional device description generation section 10, but the model specific information table 34G4 used here is different from the conventional model specific information table 34G4. Unlike the model-specific information 14, in addition to the conventional information, it also includes designation information 50 of required program modules for the model, and each item of the device description table 36 includes:
Both image information is stored as model-specific information.

The control program generation unit 40 no longer needs to have the conventional module table 23, and in the process, each item of the device description table 36 is sequentially scanned to determine a required program module.

With the above configuration, when adding/changing a model, it is only necessary to maintain the model-specific information table 34.

〔Example〕

In FIG. 1, the device description generation section 30 receives a command input in processing step 11 in the same way as the conventional device description generation section 10, determines the end of device description table generation in step 7 block 12, and Step 13 searches the model specific information table 34 for specific information.

Unlike the conventional model-specific information table 140, the model-specific information table 34, as shown in FIG. do.

In step 35, one item of the device description table including this specification information 50 is created and added to the device description table 36. Other processing is performed in the same manner as before, and the process returns to command reception processing.

Therefore, since each item of the device description table 36 stores program module specification information, the control program generation unit 40 does not need to have the conventional module table 23, and in step 42, the control program generation unit 40 stores the device description table 36. , and extracts the necessary program module specification information by scanning one item at a time.

From step 24 onwards, as in the past, the specified information to be retrieved sequentially is logically summed on an appropriate register, and step 25
It is determined whether all items in the device description table 36 have been processed. If not, the process returns to step 42. When all the devices have been processed, the process proceeds to step 26, where a control program including the designated module is generated.

With the above configuration, when adding/changing a model, there is no need for a module table, and the model-specific 1-report table 3
Only 4 needs to be maintained.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a system that generates a control program for a computer system by combining program modules that depend on the types of devices constituting the system, when adding a device model, etc. , there is a significant industrial effect of improving the economics of the system as the associated control tables are easier to maintain.
