Description

  The present invention relates to a setting value management apparatus, a setting value management method, and a program. For example, the present invention relates to a technique useful in replacing processing logic used in equipment such as a plant and managing setting values used in the processing logic.

  Conventionally, in various plants such as a rolling plant and a power plant, the operation is generally controlled by a digital control device (computer) that inputs and outputs digital data. The program executed by the digital control device is created by the program creation device based on a logic diagram in which processing logic is described.

  When the program creation device creates a program from a logic diagram, the logic diagram is input in a module-divided form, and the compiler analyzes the logic diagram to create an intermediate source program. Thereafter, the intermediate source program is analyzed by the linker and then loaded into the digital control device, so that the digital control device can execute the program. The program is displayed on the monitoring screen in the form of a logic diagram, and is used for monitoring the operation of the digital control device.

  Here, in the plant, for example, the temperature of steam used in equipment such as boilers and turbines is measured with a sensor such as a thermocouple, and the operation value of the equipment is calculated based on the engineering value obtained by converting the measured value output by this sensor into the engineering value I know the situation. In the following description, assigning engineering values measured within a predetermined measurement range equally to the predetermined range is referred to as “normalization”. For example, when the engineering value changes between 0 ° C. and 300 ° C., the normalized set value changes between 0% and 100%. In this way, the facility is controlled by the processing logic using the normalized set value obtained as a percentage so that the lower limit value of the engineering value is 0% and the upper limit value is 100%.

  In recent years, along with the development of information processing technology, a large number of digital control devices connected via a network autonomously control the operation of facilities, and the digital control devices have set values that are normalized in real time. A distributed control system that can be acquired has been constructed. As described above, in the distributed control system, since each facility autonomously controls the operation, maintenance or the like can be performed for each facility.

  Here, there is a case where the processing logic used in the distributed control system is newly replaced with another processing logic to update the distributed control system. At the time of this update, the new processing logic to be replaced is required to perform the same operation before and after replacement by taking over the operation controlled by the existing processing logic as it is. That is, the engineering value calculated by the existing processing logic needs to be the same as the engineering value calculated by the new processing logic. Similarly, with respect to the normalized set value, the values calculated by the existing processing logic and the new processing logic must be the same.

  When replacing the processing logic, the following procedure is used. First, the operator acquires a setting value for normalization from the existing processing logic. Next, the operator manually calculates the setting value used in the new processing logic while visually confirming the setting value. Then, the set value is manually reflected in the new processing logic. After such work, the replacement of processing logic has been completed. Here, for visual confirmation, a logic diagram in which a configuration of processing logic, a calculated set value, and the like are described is used.

  Japanese Patent Application Laid-Open No. H10-228688 discloses a technique that enables operation control condition data of a plant to be changed during execution of process control using processing logic, thereby adjusting control characteristics.

Japanese Patent Laid-Open No. 11-265201

  By the way, there are a large number of setting values that are input to and output from the processing logic. To obtain the same output results from the processing logic before and after replacement, the setting values must be calculated and managed so that inconsistencies in the output results do not occur. Don't be. However, conventionally, when the processing logic is replaced, the operator manually calculates the set value, and a large burden is imposed on the operator due to the large amount of work. In addition, since the quality at the time of control performed using the replaced processing logic becomes unstable due to a calculation error or erroneous description of the set value, it is necessary to eliminate such a human error.

  The present invention has been made in view of such a situation, and manages setting values before and after updating.

In the present invention, the first processing logic is generated from the first logic diagram representing the first processing logic and the first processing logic is used in the first processing logic from the source file indicating the processing order of the first processing logic. The setting value is extracted, and the extracted first setting value is written in the setting value management table for managing the first setting value.
Then, the first setting value read from the setting value management table is converted into the second setting value used by the second processing logic replaced from the first processing logic, and the second setting value is set as the setting value management. Write to the table.

  According to the present invention, the setting value management table in which the first and second setting values are written is automatically generated based on the first logic diagram. This makes it possible to create a logic diagram that does not cause a mismatch between the first and second setting values before and after the replacement of the processing logic, thereby reducing the burden on the operator for checking the setting values.

  Hereinafter, an embodiment of the present invention (hereinafter referred to as “this example”) will be described with reference to the accompanying drawings. In this embodiment, when replacing a part of processing logic used in a digital control device that controls the operation of a plant or the like, various setting values used in this processing logic are managed, and the replaced processing logic is used. An example applied to the setting value management apparatus 20 that reflects the setting value will be described. Note that the setting value management apparatus 20 of the present example implements a setting value management method performed by the internal blocks in cooperation by executing a program. In the following description, the existing first processing logic is called “existing logic”, and the second processing logic updated by replacing the existing logic is called “updated logic”.

FIG. 1 shows an internal configuration example of a set value management apparatus 20 that manages the correspondence between the set values of existing logic and the set values of updated logic.
The set value management apparatus 20 includes a set value management tool 21 that manages set values (engineering values and normalized values) used in existing logic and updated logic. In the existing logic and the updated logic, a set value in which a required engineering value is normalized is used for processing as an input / output parameter. The setting value management apparatus 20 includes a source file generation unit 1 that generates an existing source file D2 from the existing logic diagram D1, and the existing source file D2 is input to the setting value management tool 21.

  The set value management tool 21 is updated from the existing logic using the existing logic diagram D1 (first logic diagram) representing the existing logic and the existing source file D2 (source file) indicating the processing order of the existing logic. Manages conversion of set values to post-logic. Further, the set value management tool 21 is manually input by an operator using a logic diagram D3 (second logic diagram) after normalization update and a logic diagram D4 after engineering value update (third logic diagram), which will be described later. 22 is printed on a paper medium or the like, or displayed on the screen of a display device (not shown). To do. Detailed contents of these logic diagrams and the like will be described later.

  Further, the setting value management tool 21 extracts an existing logic setting value extraction unit 2 that extracts an existing normalization setting value (first normalization value) used as the first setting value in the existing logic from the existing source file D2. Converting the existing logic of the existing source file D3 to the updated logic to generate the normalized and updated logic diagram D3, and converting the existing normalization setting value (first setting value) of the existing logic to the existing engineering value The normalized engineering value conversion unit 7 for converting the setting value (first engineering value) and the existing engineering value setting value of the existing logic into the updated final setting value (second engineering value) used in the updated logic An existing post-update setting value conversion unit 9 for conversion is provided. The normalization engineering value conversion unit 7 and the existing post-update setting value conversion unit 9 convert the existing normalization setting value read from the setting value management table 15 into an updated final setting value used by the post-update logic replaced from the existing logic. Then, it is used as a set value conversion unit for writing the updated final set value in the set value management table 15.

  Further, the set value management tool 21 reflects the final updated set value (second engineering value) used in the post-update logic on the normalized post-update logic diagram D3 generated by the conversion unit 4 to perform engineering. The update unit 11 that generates the logic diagram D4 after the value update, and the engine value extraction unit that extracts the second engineering value of the updated logic from the logic diagram D4 after the engineering value update as the logic diagram current value A logic current value extraction unit 12 and a collation unit 14 that collates the updated final set value with the logic diagram current value and outputs a collation result to the collation result list D5.

Hereinafter, an operation example of each unit will be described.
The existing logic diagram D1 is a diagram that describes the processing logic used in an existing plant or the like, and the existing source file D2 is a diagram that lists the processing logic in the order of processing. In the existing logic diagram D1, information on a macro for automatically performing a plurality of processes (hereinafter abbreviated as “macro information”) is described as an example of processing logic, and this existing logic diagram D1 is used during operation of the plant. The operation state of the plant and the process amount are controlled based on the control logic described in (1).

  The macro information includes, for example, a macro name and an input / output address of a parameter input / output to / from the macro, and various processes performed in the plant are expressed by combining a plurality of macros. When the existing logic diagram D1 does not exist in a server (not shown) or when the existing logic is obtained based on the existing logic diagram D1 in which the specification of the existing logic is unknown, the manual input 22 performed by the operator is input. The existing source file D2 is generated by the operation.

  The existing logic setting value extraction unit 2 has an existing logic setting value extraction function for extracting an existing normalization setting value (first setting value) used in the existing logic from the existing source file D2. For this reason, the existing logic setting value extraction unit 2 extracts the existing normalization setting values used in the existing logic from the existing source file D2 input from the source file generation unit 1, and manages the existing normalization setting values. The existing normalization setting value is written in the existing normalization setting value field 6 of the value management table 15. At the same time, the existing logic setting value extraction unit 2 writes the existing calculation macro information of the macro extracted from the existing source file D2 in the existing calculation macro information field 3 as information related to the existing logic.

  The converting unit 4 converts the existing normalization setting value (first normalization value) extracted from the existing source file D2 into a normalized setting value (second normalization value) used by the post-normalization logic diagram D3. A conversion function for converting to). Here, when the setting value used in the existing logic represented in the existing source file D2 is a normalized existing normalization setting value, the conversion unit 4 uses the existing normalization setting value in the updated logic. Is converted into a second normalized value. Then, the converting unit 4 generates a normalized and updated logic diagram D3 in which the second normalized value is reflected in the updated logic, and sets the existing calculation macro information, the updated calculation macro information, and the existing normalization setting value. Write to the updated calculation macro information field 5 of the value management table 15.

  Here, when the conversion function of the conversion unit 4 is not used, the existing logic setting value extraction unit 2 automatically generates the existing calculation macro information field 3 and the existing normalization setting value field 6 provided in the setting value management table 15. The information written in the existing calculation macro information field 3 and the existing normalization setting value field 6 is automatically extracted from the existing source file D2 through the existing logic setting value extraction unit 2. At this time, when the conversion function of the conversion unit 4 is not used, the existing logic setting value extraction unit 2 uses the existing calculation macro in the setting value management table 15 as the macro information of the macro included in the existing logic extracted from the existing source file D2. Write to the information field 3 and write the existing normalization setting value to the existing normalization setting value field 6.

  Further, an unknown format is used in the existing logic diagram D1, and it is assumed that it is difficult for the existing logic set value extraction unit 2 to automatically extract the set value. In this case, the operator reads the existing source file D2 visually, and the updated calculation macro information is obtained by manual input 22 performed by the worker, and the updated calculation macro information field of the setting value management table 15 as information about the updated logic. 5 is written.

  On the other hand, when the conversion function of the conversion unit 4 is used, the conversion unit 4 automatically generates the existing calculation macro information field 3, the post-update calculation macro information field 5, and the existing normalization setting value field 6 provided in the setting value management table 15. To do. At this time, the conversion unit 4 writes the macro information of the macro included in the existing logic as the existing calculation macro information in the existing calculation macro information field 3, and the post-update logic as the post-update calculation macro information in the post-update calculation macro information field 5 Write the macro information of the macro contained in. Further, the conversion unit 4 writes the normalized setting value (first normalization value) used in the macro included in the existing logic as the existing normalization setting value field 6.

  Then, the normalized engineering value conversion unit 7 converts the existing normalized setting value read from the existing normalized setting value field 6 of the setting value management table 15 into an engineering value (first engineering value). ) Is written into the existing engineering value set value field 8 of the set value management table 15.

  Next, in the updated final set value field 10 provided in the set value management table 15, the settings read from the existing calculation macro information field 3, the post-update calculation macro information field 5 and the existing engineering value setting value field 8 are read. As an engineering value obtained by converting the value, an updated final setting value (second engineering value) used in the updated logic is automatically input through the existing updated setting value conversion unit 9. At this time, the existing updated set value conversion unit 9 updates the existing engineering value setting value based on the existing calculation macro information and the updated calculation macro information read from the setting value management table 15 and the existing engineering value setting value. The updated final set value (second engineering value) used in the post-logic is converted, and the updated final set value is written in the post-update final set value field 10 of the set value management table 15.

  The reflecting unit 11 adds the updated final setting value (second engineering value) read from the updated final setting value field 10 of the setting value management table 15 to the updated logic represented in the normalized post-update logic diagram D3. Reflecting this, a logic diagram D4 after engineering value update is generated. At this time, the reflection unit 11 represents the normalized second normalization value used in the post-update logic diagram D3 generated by the conversion unit 4 from the set value management table 15. An engineering value-updated logic diagram D reflected by the read updated final set value (second engineering value) is generated. However, when the logic diagram D3 after normalization update does not exist, the logic diagram D4 after engineering value update is input by the manual input 22.

  The updated logic current value extraction unit 12 is generated by the reflection unit 11 or when the conversion unit 4 is not used, the logic diagram current value (first value) extracted from the engineering value updated logic diagram D4 generated by the manual input 22. 2) is used as an engineering value extraction unit for writing the current value in the logic diagram current value field 13 of the set value management table 15.

  The collation unit 14 is converted by the logic diagram current value (second engineering value) extracted by the updated logic current value extraction unit 12 and the existing updated setting value conversion unit 9 and read from the updated final setting value field 10. The updated final set value (second engineering value) is collated, and a collation result list D5 is output as a collation result. As a result, the user can discriminate whether or not the engineering value-updated logic diagram D4 created by the manual input 22 is equal to the set value used in the automatically-updated logic.

FIG. 2 shows a description example of the existing logic diagram D1.
The existing logic diagram D1 describes the existing logic and parameters to be input to and output from the existing logic. In this example, the processing logic used to set the flow rate of the supernatant water in the limestone slurry tank is described along with the macro processing order indicated by the numbers in each block. Note that “existing macro” is defined as an example of the existing logic described above, and “updated macro” is defined as an example of the updated logic described above.

  In this example, the setting value and the like will be described by paying attention to the macro 23 among a plurality of macros shown in the drawing. The macro 23 has a function of outputting a predetermined value based on a plurality of input values, the macro name being represented as “AW”. As shown in the figure, in the macro 23, 1.0, 1.0, 0 are set for the gains G1 to G3, 0 is set for the bias B, 100 is set for the upper limit value HL, and the lower limit is set. The value LL is set to 0. The macro 24 is a “large macro” that is an aggregate of a plurality of macros, and will be described later with reference to FIG.

FIG. 3 shows an example of macro functions in the existing logic and the updated logic. In this example, an example in which the macro 23 is replaced with a macro 25 (see FIG. 6 described later) will be described. 3A shows a function example of a macro AW (hereinafter “existing AW”) in the existing logic, and FIG. 3B shows a function example of the macro AW (hereinafter “updated AW”) in the updated logic. Indicates a function example of a macro LIM (hereinafter, “updated LIM”) in the updated logic.
The macro 25 (see FIG. 6 to be described later) in the post-update logic performs a process equivalent to the existing AW by using the post-update AW and the post-update LIM obtained by dividing the function of the existing AW. In the following description, HL represents the first threshold value of the output value Y, and LL represents the second threshold value of the output value Y. The first and second thresholds satisfy the relationship LL ≦ HL.

  As shown in FIG. 3A, the macro 23 in the existing logic has an adder with gain and bias, and outputs an output value Y when three input values X1 to X3 are inputted. The macro 23 determines the gains G1 to G3 and the bias B by the mathematical formula shown in the line including the existing AW, and the output value Y is obtained. The output value Y is limited so that it falls within the range of LL ≦ Y ≦ HL.

  As shown in FIG. 3B, the updated AW included in the macro 25 in the updated logic outputs an output value Y when three input values X1 to X3 are input. The macro 25 determines the gains G1 to G3 and the bias B by the mathematical formula shown in the row including the updated AW, and the output value Y is obtained. The output value Y output from the updated AW is not limited.

As shown in FIG. 3C, the updated LIM included in the macro 25 in the updated logic outputs the output value Y when the input value X is input. The output value Y output by the LIM after this update is limited with respect to the input value X as shown in the following three conditions.
(1) If X> HL, Y = HL.
(2) When LL ≦ X ≦ HL, Y = X.
(3) When X <LL, Y = LL.

FIG. 4 shows a description example of the existing source file D2.
The existing source file D2 is managed by the setting value management device 20. One or a plurality of existing source files D2 are stored in a directory format in the controller name folder arranged in the temporary folder. In the existing source file D2, macro information such as a macro name and a macro input / output address is described together with a macro processing procedure.

  Here, the header information of the file is described in the first line at the top of the existing source file D2, and the updated macro sheet number and the like are described. In the second line, a value is set at the time of macro integration or division. In the third and subsequent lines, macro information is described in accordance with the macro numbers indicating the macro operation order shown in FIG.

FIG. 5 shows an example of a function for writing the macro setting values described in the existing source file D2 into the setting value management table 15.
This writing is performed using an existing logic setting value extraction function of the existing logic setting value extraction unit 2 or a conversion function of the conversion unit 4. This example shows an example in which the same symbol as that in the existing macro exists in the macros of the existing calculation macro information field 3 and the updated calculation macro information field 5.

  The existing source file D2 includes an existing macro name field for storing an existing macro name, a symbol field for storing an upper limit value or a lower limit value of a setting value used in the macro, and a setting value field for storing a setting value. . In the existing macro name field of the existing source file D2, the name of the macro “DG2” representing the macro 24 in FIG. 2 is written. In the symbol field, symbols “T”, “HH”, “LL”, “HH”, and “LL” are written in order from the top record. Here, “T” represents the minimum value of the step size of the changing set value. The setting value (first normalization value) corresponding to the symbol written in the symbol field is written in the setting value field of the existing normalization setting value field 6.

  The existing calculation macro information field 3 shown in FIG. 1 includes an existing macro name field and a symbol field, and the existing normalization setting value field 6 includes a setting value field. When the existing source file D2 passes through the existing logic setting value extraction unit 2 or the conversion unit 4, the setting values (first normalized values) in the setting value field are rearranged. In this example, a set value (first normalization value) in which the arrangement order is changed in accordance with symbols “HH”, “HH”, “LL”, “T”, “LL” whose arrangement order is determined in advance. ) Is written in the existing normalization setting value field 6.

  Specifically, the setting value is stored in the existing calculation macro information field 3 with priority given to the order (row order) in the setting value management table 15. For example, consider a case where the setting values extracted from the setting values 107 to 111 of the existing macro 101 are stored in the setting values 118 to 122 of the existing normalization setting value field 6. At this time, after matching symbols 102 to 106 of the existing macro 101 and symbols 113 to 117 of the existing macro 112 are found through the existing logic set value extraction unit 2 or the conversion unit 4, the set values are stored according to the symbols. To do. For example, since the symbol 102 (“T”) of the existing macro 101 matches the symbol 116 (“T”) of the existing macro 112, the setting value 107 (“1.0000”) of the existing macro 101 is the setting of the existing macro 112. It is stored in the value 121 (“1.000”).

  Further, when the same symbol is used, such as the symbol 103 (“HH”) and the symbol 105 (“HH”) of the existing macro 101, the setting value management table 15 is given priority in the order (line order) in the existing source file D2. The setting value is stored in the existing calculation macro information field 3. Therefore, the setting value 108 (“100.0000”) of the symbol 103 (“HH”) of the existing macro 101 is changed to the setting value 118 (“100.0000”) of the symbol 113 (“HH”) of the existing macro 112. Stored. On the other hand, the setting value 110 (“50.0000”) of the symbol 105 (“HH”) of the existing macro 101 is stored in the setting value 119 (“50.0000”) of the symbol 114 (“HH”) of the existing macro 112. Is done.

FIG. 6 shows a description example of the logic diagram D4 after engineering value update.
As shown in the macro 25, in the updated macro, the macro AW included in the macro 23 shown in FIG. 2 is divided into a macro AW and a macro LIM. Here, it is shown that each parameter is also divided and distributed to the macro AW and the macro LIM. As shown in the figure, in the updated AW of the macro 25, the gains G1 to G3 are set to 1.0, 1.0 and 0.0, respectively, and the bias B is set to 0.0 [t / h (tons). / Time)], 60.0 [t / h] is set to the upper limit value HL, and 0.0 [t / h] is set to the lower limit value LL in the updated LIM. Thus, the setting value converted into the engineering value is reflected in the macro 25 in the updated AW and the updated LIM.

FIG. 7 shows an example of detailed data of the set value management table 15.
The set value management table 15 is created based on a template sheet created in advance for each type of existing macro, using spreadsheet software executed by the set value management apparatus 20. In this spreadsheet software, one file can have a plurality of sheets, and one sheet manages one type of existing macro and macro information of an updated macro corresponding to this.

  The set value management tool 21 is set in the sheet as a calculation formula for automatically converting a parameter required for each field in the sheet shown in FIG. 7 into a normalized value or an engineering value. . Here, when the number of necessary parameters differs between the existing macro and the updated macro, an empty cell in which an arbitrary value can be input is set in the set value management table 15. In the empty cell, zero is displayed as the value input to the cell. However, a hyphen “-” may be displayed in an empty cell in which no data is input in order to identify whether there is no data itself.

  When a large macro is generated by combining a plurality of macros used in the updated macro, the large macro recognition number is set as the macro recognition number representing the updated macro assigned to uniquely recognize the macro. Here, the macro name assigned to the “large macro name” in the large macro attribute is set.

  Note that a cell composed of a plurality of rows is created in a cell combination state in which a plurality of cells are combined into one cell. The reason for creating a cell in this way is that it is necessary to automatically determine the number of rows allocated to one macro based on the number of rows occupied by the “NO.” Column. In the cell combination state, since the value is stored in the cell in the first row, it is easy to read the value from the cell or write the value to the cell. For the number of digits after the decimal point, since the cell display format has priority, it is required that the attribute (display format) of each cell is accurately defined in the template sheet.

  In the setting value management table 15, a plurality of types of columns are further subdivided as described above with reference to FIG. Here, the macro names of the existing logic and the updated logic are set in the template sheet. Then, the existing logic setting value extraction unit 2 writes the setting values extracted from the existing source file D2 in the loop sheet number field and the block number field in the existing calculation macro information field 3.

  When the conversion function is used, the conversion unit 4 automatically writes the updated macro information in the logic sheet number field and the recognition number field of the updated calculation macro information field 5. However, when the conversion function is not used, the operator manually inputs macro information. Further, the existing engineering value set value field 8 and the updated final set value field 10 are automatically input using the normalized engineering value conversion unit 7 and the existing updated set value conversion unit 9, respectively. In the logic diagram current value field 13, the current value extracted from the engineering value updated logic diagram D4 is input.

FIG. 8 shows a description example of the matching result list D5.
In the collation result list D5, differences for each macro read from the updated final set value field 10 and the logic diagram current value field 13 are described in the order of records described in the set value management table 15. When there is a difference, it is described how many different points exist, and when all the points match, it is described that there is no difference.

  According to the setting value management apparatus according to the present embodiment described above, the setting value extracted from the existing source file D2 generated from the existing logic diagram D1 in which the existing processing logic is described is written in the setting value management table 15. . Then, after the set value conversion is performed on the set value management table 15, the set value is converted in accordance with the replaced processing logic, and the set value management table 15 automatically manages the converted set value. Therefore, the normalized and updated logic diagram D3 and the engineering value and updated logic diagram D4 can be automatically generated from the set value management table 15. As described above, since the work from the creation of the set value management table 15 to the maintenance is automatically performed, the time required for checking the set values is reduced when the processing logic is replaced from the existing logic to the updated logic. At the same time, it is possible to support the improvement of the quality of the logic diagram generated after the processing logic is replaced.

  Further, the engineering value is written in the setting value management table 15 by converting the setting value normalized in the existing processing logic into the engineering value, and then converted into the setting value used in the processing logic for reading and replacing the engineering value. Then, this set value is written in the set value management table 15. For this reason, the operator can check the setting values used in the processing logic before and after replacement at a glance and determine whether or not the setting values are appropriate.

  Further, the conversion unit 4 converts the processing logic represented in the existing source file D2 to generate a normalized and updated logic diagram D3. Then, the reflecting unit 11 generates the engineering value updated logic diagram D4 in which the engineering value read from the normalized updated logic diagram D3 is reflected in the setting value read from the updated final setting value field 10. For this reason, it is possible to easily generate a logic diagram in which an engineering value is reflected on a logic diagram generated using the conventional conversion unit 4.

  Further, there is a case where an engineering value-updated logic diagram D4 is created by updating the engineering value from the existing logic diagram D1 by the manual input 22 of the operator. In this case, the engineering value updated logic diagram D4 is automatically checked by collating the current value extracted from the engineering value updated logic diagram D4 against the setting value reflected in the setting value management table 15. It is possible to ascertain whether or not there is an error in the setting value set in error. Also, a collation unit that collates whether the updated final setting value written in the updated final setting value field 10 in the setting value management table 15 matches the logic diagram current value written in the logic diagram current value field 13. 14, the collated result is automatically generated as a collation result list D5. For this reason, the quality of the set value described in the logic value D4 after engineering value update created by the manual input 22 can be appropriately determined.

  Note that the set value management device 20 according to the above-described embodiment may be applied to a social infrastructure using a transmission / substation, a railway system, a smart grid, and the like in addition to a plant such as a power plant. Even in this case, it is possible to accurately replace the existing processing logic with another processing logic.

  The series of processes in the above-described embodiment can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, it can be executed by a computer in which a program constituting the software is incorporated in dedicated hardware or a computer in which programs for executing various functions are installed. is there. For example, a program constituting desired software may be installed and executed on a general-purpose personal computer or the like.

  Further, a recording medium on which a program code of software that realizes the functions of the above-described embodiments may be supplied to the system or apparatus. It goes without saying that the function is also realized by a computer (or a control device such as a CPU) of the system or apparatus reading and executing the program code stored in the recording medium.
