Field of technology

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program execution control method when editing a program of a control device, an inspection device, a measurement device, and the like, and more particularly, to a program execution control method that can switch contents of a program to be executed at execution time.

Prior art

In the program development process, when debugging a program, in order to confirm the partial operation of the developed program, a part which is not related to the operation confirmation may be commented out and executed. In addition, a program related to the developed program may be commented out and described in the same program.

To comment out, add a symbol for comment out to the program. Attempts have been made to apply such a comment out function to graphical programming that handles graphic information such as flow charts and block diagrams (see Patent Document 1, for example).

Patent Literature 1 discloses, for example, a technique of designating an area to be treated as a comment out in the program editing area so as not to code the code in order to realize a function of annotating in the drawing. That is, an area to be treated as a comment is designated in the program area, and a predetermined program object is surrounded by this area to determine whether each object is treated as a program or as a comment.

[Patent Document 1]

Japanese Patent Application Laid-Open No. 2-14370 (Patent No. 2851852)

By the way, in the programming method of converting the program to the execution code when executing the program, in order to reflect the changes to the program such as the comment out at the time of execution, it is necessary to convert the program again to the execution code before executing the changed program. . Every time a comment position is converted, the program is converted into an execution form, the converted execution form is downloaded to the program execution means, and the start of execution is instructed. In particular, in a system that takes a long time to change or download a program to executable code, such a process needs to be performed every time the program is changed, which causes a problem that the development efficiency of the program is lowered.

In addition, depending on the program, if a part of the program is executed or not executed while the program is executed online, the program may not be syntactically correct and execution may be stopped.                         

In addition, if an execution flag is set in a program, a program to be executed because it is set effectively and an invalid program because it is not set will exist, making it difficult to determine which part of the program is actually executed. There is also a problem that the readability is reduced.

It is a first object of the present invention to provide a program execution control method which does not need to be converted into an executable form each time a program is edited.

A second object of the present invention is to provide a program execution control method having a program checking means for checking whether a program is a grammatically correct program and detecting an indefinite portion of the program.

A third object of the present invention is to provide a method for controlling execution of a program with high readability by reducing the description for conditional branching in a program.

The execution control method of the program of the present invention includes program creation means for creating a program in a function block format, and program execution means for executing a program created by the program creation means, and executes the function block on the function block. An execution flag for deciding whether or not to be provided is provided, and it is possible to operate ON / 0FF of the execution flag during the stop or execution of the program described by the function block, and only the function block for which the execution flag is valid is executed. It is to be executed by the execution means.

In addition, the execution control method of the program of the present invention checks whether the program is grammatically correct as a result of operating the execution flag of the function block. The program confirmation means to detect was provided.

In addition, the execution control method of the program of the present invention provides a valid function block detecting means for detecting a function block having an effective execution flag, and displays only the function blocks that have been set and are executed at the time of execution on the program display means. It is.

Example 1

EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, embodiment of this invention is described.

1 is a block diagram showing a system configuration used in the program execution control method of the present invention. The system includes a CPU (central computing unit) 100, a ROM (lead only memory) 101, a RAM (random access memory) 102, a display device 103, and I / O as hardware resources. (Input / Output Device) 105, D / A (Digital Analog Converter) 106, and A / D (Analog Digital Converter) 107.

These are connected via a bus, but not all of them need to be equipped, and if the analog inputs are not handled, there may be no A / D 107, or the D / A 106 if the analog outputs are not handled. There is no need to. In addition, when it is not necessary to display on a screen, the display apparatus 103 can be abbreviate | omitted.

For example, the ROM 101 stores an operating system and a program for controlling the operation of the system, and the RAM 102 stores a program or data created by a user. The CPU 100 executes various functions by a program for controlling the operation of the system stored in the ROM 101.

2 is a functional configuration diagram showing the operation of the system according to the first embodiment of the present invention, wherein the CPU 100, the ROM 101, the RAM 102, the display device 103, and the input device 104 are shown. It is executed by various processes. For example, the CPU 100 functions as the display means 207 together with the display device 103, functions as the operation means 206 together with the input device 104, and the ROM 101 and the RAM. And function as a means 202 for executing a program created by a user, such as a function block execution means, together with the 102, and as an input means 204 together with the I / 0 105 and the A / D 107, It functions as an output means 205 together with I / 0 105 and D / A 106. The display device 103 is made of LCD, for example, and can display the execution status of the user program. The input device 104 consists of a touch panel attached to a keyboard or LCD, for example, and can switch the instruction | indication and process of execution of a program.

Next, various functions executed by the CPU 100 will be described with reference to FIG. 2.

The program creation means 200 is a means for creating a program for realizing a desired operation by the user. This means may exist on the same hardware as the program execution means 202, or may exist on other hardware. If it exists on other hardware, the program created there is transmitted on the same hardware as the program execution means 202 using a communication means. In the program creation means 200, a user creates a program by a program language such as a function block, but since the program execution means 202 cannot be executed as it is, the program language can be executed by the program execution means 202. The program is stored in the program storage means 201 once.

The program storage means 201 is a means for saving a program created by the program creation means 200. The program execution means 202 is a means for reading and executing a user program created by the program creation means 200 and stored in the program storage means 201. The program execution means 202 receives data from the data storage means 203 based on the operation instruction described in the program, processes the data, and outputs the data to the data storage means 203 again. In addition, the program execution means 202 receives the user's instruction from the operation means 206 and performs a corresponding process, and displays the execution status of the program on the display means 207. When the execution result is stored, the execution result is output to the execution result storage means 208.

The input means 204 and the output means 205 operate periodically or under the instruction of the program execution means 202, and input and output data stored in the data storage means 203 with an external connection device.

3 shows an example of a function block diagram (hereinafter referred to as FBD) used when a user creates a program. FBD is a program described by a function block (hereinafter referred to as FB). In this figure, when the process of FB1 31 is complete | finished, the process result in FB1 31 is input into FB232. Next, when the processing in the FB2 32 ends, it is input to the FB3 33. Finally, the processing result of the FB3 33 is output.

In this manner, in the FBD, the data processed by the individual FBs is given as input to the FBs connected by the connection lines. The value of the data storage means 203 is input to the head FB, and the value output from the last FB is output to the data storage means 203 again.

As described in the section of the background art, in the stage of program development, in order to partially check the operation of the program, it is sometimes necessary to comment out a part which deviates from the object of the operation confirmation. However, in order to comment out the program created by the user, it is necessary to change the program on the program creation means 200, and to execute the changed program, it is converted into an execution form and stored in the program storage means 201. After that, it is necessary to read the program execution means 202. It is not efficient to perform this series of operations every time the comment-out location is changed, and the program development efficiency is not high.

Therefore, in the first embodiment, an execution flag is provided in each FB, and when the program is executed by the program execution means 202, only the FB with the program execution flag is executed. In addition, ON / OFF of an execution flag shall be performed on the program after conversion to an execution form, without editing a program in the program creation means 200. FIG. For the operation of turning ON / OFF the execution flag, if the actual machine that executes the FBD has a display device such as an LCD, the ON / OFF operation is performed using the input device while watching the FBD displayed on the display device. It is possible to do It is also possible to display only execution flags on the screen without displaying the FBD, and to perform ON / OFF operations on the actual machine. In addition, when the actual machine that executes the FBD is connected to a program development environment such as a personal computer, it is also possible to display the FBD on the program development environment and operate the execution flag of the desired FB.

Whenever the position of the comment out is changed, it is not necessary to edit the program in the program creation means 200, and to read the program execution means 202 again after converting it to an execution form, thereby improving the development efficiency of the program.

Next, the means of realization will be described.

Fig. 4 is a diagram showing an example of an FB in which an execution flag is provided. Fig. 4 (a) shows that the execution flag 42 is checked, and this FB 41 is executed. On the other hand, Fig. 4B shows that the execution flag 42 is not checked and that the FB 41 is not executed. An example of the FBD described by the FB with the execution flag 42 is shown in FIG. In FIG. 5, the execution flag 42 is checked in the FB1 31 and FB3 33, but the FB2 32 is not executed because the execution flag 42 of the FB2 32 is not checked. For this reason, the program is equivalent to the FBD shown in FIG.

In this example, the FB with the checkmark in the execution flag is determined to be valid, and the FB without the check is executed. However, the FB with the checkmark in the execution flag is not executed. Alternatively, the FB may be executed without checking the execution flag.

Therefore, the operation result of each FB is substituted into the variable for saving the operation result, and the value of this variable becomes an input of the FB executed next. Therefore, if there is an FB not executed in the continuous FBs, the processing of the FBs is not reflected in the resultant value, and the same result as the comment out can be obtained.

7 shows an example of the data format of the FB in which the execution flag 42 is provided. The data of each FB includes the ID 71 of the function block for specifying the FB, the execution flag 72 for controlling execution, the inputs 1 and 73 for storing data of the connection line connected to the input pin of the FB, and It consists of the input (2) 75 and the output (1) 75 and the output (2) 76 which similarly store the data of the connection line connected to an output pin. The information of the execution flag 42 may be included in the data format of the FB in this manner, or a region containing only the execution flag 42 in a collective manner is stored, and the corresponding execution flag 42 is referred to from each FB. good.

Next, processing by the program execution means 202 will be described with reference to FIG. 8. The program execution means 202 reads one FB from the program (step 81). It is determined whether the execution flag 42 of the FB is valid or invalid (step 82), and if it is valid, the processing of the FB is executed (step 83). If it is invalid, the processing of the FB is not performed. Next, one program counter indicating the FB to be executed is advanced (step 84). Then, it is determined whether the end of the program has been reached (step 85). If the end of the program is reached, the program is terminated. If there is a continuation, the program moves to the next FB reading.

The ON / OFF of the execution flag 42 can be operated by the operation means 206 while checking the FBD displayed on the display means 207, while checking the FBD displayed on the program creation means 200. It is also possible to operate. Since these operations are performed on the FBD after conversion to the execution form, there is no need to convert the program to the execution form after the operation.

Fig. 9 is a FBD showing a method of adding a conditional statement as a method of switching the flow of execution without changing the execution format. In the figure, the conditional statements 91 and 92 are added, so that an FB different from the process originally described by the program is added to the program. The result is poor code readability and maintainability. Therefore, this is not preferable as compared with the method of providing the execution flag 42 in each FB.

As described above, when there is a part to be commented out of the program, the execution flag of the corresponding place is invalidated and the same effect as the comment out can be obtained without converting the program to the execution format. In addition, since the conversion work of the program is not necessary during program creation, the development efficiency of the program can be improved.

Example 2

Fig. 10 shows an embodiment in which a program confirmation means 1002 is provided on a program development environment for determining whether it is grammatically correct as a program. The program checking means 1002 is a means for determining whether the FBD 1001 is grammatically correct by operation of ON / OFF of the execution flag 42 of which FB. The program confirmation means 1002 may exist on the actual machine that executes the FBD.

The program checking means 1002 operates immediately after performing the switching operation of the execution flag 42, and checks the grammar of the program. Then, the confirmed result is displayed on the program display means 1003. The program display means 1003 displays a program, and examples thereof include display portions of the display means 207 and the program creation means 200.

Next, the flow of the program confirmation means 1002 will be described with reference to FIG.

The program confirmation means 1002 is activated every time when the execution flag 42 of the FB is operated. When the program confirmation means 1002 starts up, the program is read (step 111), and it is checked whether the program is grammatically correct (step 112). Next, it is checked whether the program is syntactically correct (step 113). If the program is grammatically correct, the program display means 1003 indicates that there is no problem with the program. On the other hand, if the program is grammatically incorrect, for example, an incorrect part of the program is highlighted (step 114).

12 and 13 show examples of the display of the program display means 1003. In Fig. 12, the execution flag 42 of the FB12 123 having two inputs and one output is turned OFF. If the FB12 123 is invalid, this FBD cannot be executed because it is not syntactically valid. Thus, the incorrect part is highlighted as shown in FIG.

In this example, the width of the line is thickened to emphasize the wrong part, but the wrong part can be emphasized by various methods such as changing the color of the line or changing the color of the background.

By highlighting the incorrect part in this way, it is easy to identify the part where the problem occurs.

Example 3

14 shows an example of an FB having a replacement FB 141 executed when the execution flag 42 of the FB is 0FF. In this example, the FB12 123 is the replacement FB 141 and stores the FB of AND. Since the execution flag 42 of the FB12 123 is 0FF, the FB (AND) 141 is executed instead of the FB12 123 at the time of execution. On the other hand, when the execution flag 42 is ON, the FB12 123 is executed.

An example of the data format of an FB with a replacement FB 141 is shown in FIG. 15. The ID 151 of the replacement FB is added to the normal PB day format. When the execution flag 42 is 0FF, the ID 151 of the replacement FB is read and executed.

Thus, by separately storing the replacement FB 141 executed when the execution flag 42 is set to 0FF, it is possible to prevent the program from being grammatically denied by the operation of the execution flag 42. In addition, since the execution contents of the program can be switched without changing the program and reconverting to the execution form, debugging can be made more efficient, such as registering a debug FB.

Also, in this example, one replacement FB 141 is described for one FB, but one circuit consisting of a plurality of FBs may be registered for one FB.

Example 4

The rewriting of the execution flag of the FB may be either while the program of the FBD is stopped or while it is being executed. There are two methods for rewriting the execution flag of the program of the FBD: a method performed on a practical machine, and a method performed on a program development environment realized on a personal computer or the like.

16 shows an example in the case where rewriting of the execution flag of the FB is performed on the actual machine. The execution flag operation means 161 is a means for operating the execution flag 42 of each FB of an FBD. The execution flag operation means 161 includes means for displaying the state of the execution flag, such as displaying an FB on a screen of the actual machine or listing and displaying display components corresponding to the execution flag, and operation of the execution flag 42. This is realized by the actual input device 104 which performs the operation. When the actual machine does not have a display screen, the execution flag 42 is associated with the input device 104, and the execution flag 42 is operated in accordance with the input.

The execution flag operated by the execution flag operation means 161 confirms whether it becomes a grammatically correct program by the actual program confirmation means 1002.

When the program is executed in the program development environment, the execution flag operation means 161 and the program confirmation means 1002 in FIG. 16 exist on the program development environment, and it is confirmed whether the newly set execution flag combination is grammatically correct. The combination of the execution flags that are grammatically established is reflected in the program of the execution form.

Whether the program checking means 1002 exists on the actual machine or on the program development environment, the program checking means 1002 exists in the program of the execution form when the program does not set the execution flag 42 that is grammatically correct. The execution flag 42 is not changed at all.

In this way, when rewriting the execution flag 42 online, after confirming that it is grammatically correct by the program checking means 1002, the operation of the execution flag 42 is caused by simultaneously switching the execution flag 42 of the FB. This can prevent a syntax error from occurring in the processing of the FBD and a situation in which the processing is interrupted.

Example 5

FIG. 17 shows an embodiment in the case where execution flag control means 171 for performing the operation of the execution flag 42 in the program is provided in the program. As one of the FBs, an FB for operating the execution flag 42 of the designated FB is provided. In this FB, the identification number of the FB to be operated by the execution flag 42 is specified. The identification number is a number capable of specifying one FB to be operated by the execution flag 42.

When the program execution means 202 reads the FB for operating the execution flag 42, it calls the execution flag control means 171 and performs the operation of the execution flag 42. The operation of the execution flag 42 may be turned from ON to OFF, or may be set from 0FF to 0N.

The FB to be executed can be selected by operating the execution flag 42 of the designated FB from among the programs. For this reason, the process of switching the FB to be executed according to the execution situation becomes possible.

The control of this execution flag 42 is also applicable to an FB having a replacement circuit. In addition, the execution flag 42 can be operated after confirming the program.

Example 6

In the sixth embodiment, the character string is set as the execution flag 42.

18 shows an example of the system configuration in this case, and the program execution means 202 compares and matches the character string set in the execution flag 42 with the character string stored by the valid character string storage means 181. The FB having the execution string 42 in the execution flag 42 is executed.

The effective character string storage means 181 is a means for saving a character string for comparison with a character string described in the execution flag 42 of the FB, and can save a plurality of character strings. When the character string is described in the execution flag 42 of the read-out FB, the program execution means 202 checks whether a matching character string exists in the valid character string storage means 181, and when there is a matching character string, Run that FB.

An example in which a character string is described in the execution flag 42 is shown in FIG. The execution flag 42 may describe not only ON / OFF but also a character string. This example describes "DEBUG" as a string.

When a character string is designated, only the FB having the character string defined as valid among the program execution means 202 is executed. FBs with strings that are not defined as valid will not be executed. In addition, the FB in which nothing is set in the execution flag 42 is executed as it is.

If " DEBUG " exists in the valid character string storing means 181, FB31 192 and FB41 195 are executed. On the other hand, if "DEBUG" does not exist in the valid character string storing means 181, the processing of FB31 192 and FB41 195 is not executed.

20 shows the flow of the process of the program execution means 202 in this case.

The program execution means 202 reads one FB from the program (step 2001). It is determined whether or not the execution flag 42 of the FB is a character string (step 2002). If the flag indicates 0N / 0FF rather than a character string, it is determined whether the execution flag 42 is valid (step 2003). On the other hand, when the character string is set in the execution flag 42, it is checked whether there is a matching character string in the valid character string storage means 181 (step 2004). If there is a matching character string, the corresponding FB is executed as in the case where the execution flag 42 is ON (step 2005). On the other hand, if there is no matching character string in the valid character string storage means 181, the motion is shifted to the program counter without executing the corresponding FB as in the case where the execution flag 42 is 0FF (step 2006).

After the program counter advances to the next FB, it is determined whether the end of the program has been reached (step 2007). If the end of the program is reached, the program ends. If there is a continuation, the program moves to the next FB reading. The character string defined as valid is specified by the program generating means 200 or the input device 104.

Before registering the character string defined as valid in the valid character string storage means 181, the program confirmation means 1002 can be used to confirm whether the program is grammatically correct by changing the valid character string.

When debugging information is desired, the same character string may be defined in the execution flag 42 of the FB having the data display function, and the same character string may be defined in the valid character string storage means 181 as valid. If the same character string is defined as valid, the FB for displaying the information is executed, and thus the operation of the program can be confirmed by the FB having the display function. On the other hand, after the operation check of the program is completed, it is possible to erase all the display by invalidating the same character string.

In addition, by setting the character string defined in the execution flag 42 of the FB for each product, a program corresponding to a variety of products can be created. 21 is an example of an FBD corresponding to two kinds of products.

If "workA" is defined in the effective character string storage means 181 after executing FB60 (211) and FB70 (214), FB61 (212) and FB71 (215) have FB62 if "WorkB" is defined. 213 and FB72 216 are executed. Describing the conversions for each product as conditional branching makes the program more readable because the conditional branching increases with increasing variety. As a method of setting a character string in the execution flag 42, since only the FB matching the character string stored by the effective character string storage means 181 is executed, it is possible to describe a program with high readability without describing a conditional branch. .

Example 7

FIG. 22 shows an embodiment in which valid FB detection means 222 is provided for detecting an FB in which the execution flag 42 is valid in the program. The valid FB detection means 222 refers to the execution flag 42 set in the FB in the program or the character string stored by the valid character string storage means 181, and performs valid processing at execution. Displays only the FB on the program display means 1003.

According to this embodiment, since only the FBs that are validly set are displayed, there is no need to individually check the execution flag 42 set for each FB, and the program can be displayed easily.

In addition, it is also possible to display the effective FB easily by changing the display color of the FB and other FBs that are set effectively.

Example 8

In the eighth embodiment, the flowchart is set as the execution flag 42.

FIG. 23 shows a system configuration diagram in this case. The execution flag 42 is set in each flow of the flowchart, and the execution of the flow is performed by the state of the execution flag 42 set in each flow. The flowchart execution means 233 which determines non-execution is provided.

The flowchart execution means 233 can replace and implement the part corresponding to FB among the means of Example 2-Example 7 by a flow.

According to the second embodiment, the program checking means 1002 can highlight and display a grammatically defective part of the program.

According to the third embodiment, the replacement flow is described in each flow, and when the execution flag 42 is 0FF or invalid, the contents described in the replacement flow can be executed.

According to the fourth embodiment, after confirming that the program is syntactically correct by the program confirming means 1002, the execution flag 42 in the program can be switched simultaneously by the execution flag operation means 161.

According to the fifth embodiment, the execution flag 42 of each flow can be operated using the execution flag control means 171 in the program.

According to the sixth embodiment, it is possible to designate a character string in the execution flag 42 of each flow, compare it with a character string stored by the valid character string storage means 181, and execute only a flow having a matching character string.

Example 9

In the ninth embodiment, the indicator is set as the execution flag 42. The display has a function of the display processing means reading the data of the display component and displaying the component indicated by the display data on the screen. FIG. 24 shows a system configuration diagram in this case. The execution flag 42 is set for the display parts, and the display / ratio of the display parts is changed depending on the state of the execution flag 42 set for each display part. Display execution means 244 for determining the display is provided.

The display execution means 244 can be implemented by applying the parts corresponding to the third, sixth, and seventh embodiments to the display components.

According to the third embodiment, it is possible to register a display component to be displayed instead of displaying the display component for one display component. In addition, according to the sixth embodiment, a character string that defines whether or not to display the display component is defined for the display component, and the display component can be displayed only when it is determined that the character string is valid. By arranging a plurality of display parts at the same coordinates and defining different character strings as valid, only valid display parts can be displayed. Further, according to the seventh embodiment, since only the display parts that are set to be valid by the effective display part detection means 242 are displayed on the edit screen, the editing work can be made more efficient.

Example 10

Fig. 25 is a diagram showing a unit configuration of an inspection system which is one object of the present invention. 25 shows an importer 300, an inspection station 301, an ejector 302, and a programmable inspection device 303 which controls them, and considers inspection. The programmable inspection apparatus 303 controls the loading machine 300 to carry the inspection object 304 into the inspection station 301. The inspection station 301 electrically connects the inspection object 304 and the programmable inspection device 303, such as attaching a jig to the inspection object 304, and inspects the inspection item described by a tabular program. Is carried out. After the inspection, the inspection object 304 is carried out from the inspection station 301 by the ejector 302.

The progress of the inspection can be confirmed on the display screen of the programmable inspection apparatus 303. In the program inspection device 303, it is possible to execute a tabular program that lists the items and flows of the inspection. 26 shows an example of a tabular program. The tabular program consists of a step number 400, a comment 401, a measurement condition setting unit 413, a measurement object setting unit 414, a determination reference setting unit 415, and a post-decision processing setting unit 416. .

When the tabular program is executed, the value described in the step number 400, the comment 401, the measurement condition setting unit 413 of the step being executed, the measurement target described in the measurement object setting unit 414, The values described in the determination criteria setting unit 415 and the contents described in the post-decision processing setting unit 416 can be displayed on the display screen.

The measurement condition setting unit 413 describes the conditions to be set for the inspection target 304 at the time of measurement. In FIG. 26, the test | inspection 304 has two cases of SW-1 and SW-2 as a switch, and has the channel CH-1 which inputs a voltage. All of SW-1, SW-2, and CH-1 in the tabular program shown in FIG. 26 are tags (names arbitrarily given by the user to the input / output device included in the inspection apparatus), and actually correspond to the data storage means 203. Device exists. In addition, these devices are connected to the inspection object 304 via the input means 204 or the output means 205. In the example of FIG. 26, in step 1, SW-1 is turned ON, SW-2 is set to 0FF, and 0.0V is applied to CH1. The measurement condition setting unit 413 can set any number of devices.

In the weight column 405, the waiting time from setting the measurement conditions to acquiring the measurement target value is specified. The difference of time constants according to the measurement object is adjusted by specifying the waiting time in the weight column. As a unit of time to set to a weight, a second, a millisecond, etc. are mentioned. After the time specified in the weight column 405 elapses, measurement is performed on the target specified by the measurement target setting unit 414. In the target column of the measurement target setting unit 414, the number of the channel for measuring the value of the inspection target 304 is specified. In the example of step 1 of FIG. 26, A / D1-CH3 is designated as an object. This shows that the value of the channel 3 on the first A / D board of the programmable inspection device 303 to which the inspection object 304 is connected is measured. The measured data is stored in the data type specified in the data type column 407, and is performed in the data type which also specifies later pass and fail judgments.

The value of the object specified by the target column 406 of the measurement target setting unit 414 is compared with the value specified by the determination reference setting unit 415, and it is determined whether the determination criteria are satisfied. The decision criterion setting unit 415 includes a minimum value column 408, a maximum value column 409, and a match comparison column 410. The minimum value column 408 describes the minimum value of the pass and fail determination criteria, and the maximum value field 409 describes the maximum value of the pass and fail determination criteria. If the measured value is in this range, the pass (OK) is judged. If the measured value does not fall within this value, the pass NG is determined. When there is no description of a value in the minimum value and the maximum value, and a numerical value is described only in the coincidence comparison column 410, it is determined whether the measured value and the numerical value described in the coincidence comparison column 410 coincide. If they match, pass (OK) is determined. If there is a mismatch, fail NG is determined.

The process described in the post-decision processing setting unit 416 is executed based on the determination result determined by comparing the value measured by the measurement target setting unit 414 with the value set in the determination reference setting unit 415. The post-decision processing setting unit 416 consists of two columns, an OK column 411 and an NG column 412. The OK column 411 describes the processing to be executed when the determination result is Pass (OK). The NG column 412 describes processing to be executed when the determination result is Fail NG. In the OK field 411 of the post-decision processing setting unit 416 of FIG. 26, a process of calling "Func1" which is another software object existing on the system is specified. When the determination result of step 4 becomes OK, this "Func1" is called and executed from tabular program execution means 273 which will be described later.

When the processing described in the determination processing setting unit 416 ends, the tabular program execution means 273 proceeds to the next step (row) of the same tabular program, so that the step number 400 and the comment 401 are entered. Read it. After displaying these on the display screen, the data described in the measurement condition setting unit 413 are output, and the remaining processing in this row is performed.

In this manner, when the processing of data in one row is finished, the processing advances to the next row. When the processing of the entire table program is finished, the table program is terminated.

In the tenth embodiment, each element of the tabular program is set as the execution flag 42.

FIG. 27 shows a system configuration diagram in this case. The execution flag 42 is set for each element of the tabular program, and the element is executed by the state of the execution flag 42 set for each element. • A tabular program execution means 273 for determining non-execution is provided.

The tabular program execution means 273 can be executed by applying the processing corresponding to the second embodiment to the seventh embodiment to the tabular program.

That is, in Example 2, it is confirmed by the program confirmation means 1002 whether the grammar of a tabular program is observed. In the third embodiment, replacement cells are prepared for cells of the tabular program. If the execution flag 42 of each cell is 0N, the contents described in the cell are executed. If the contents of the cell is 0FF, the contents described in the replacement cell are executed.

In the fourth embodiment, after confirming by using the program confirming means 1002 whether the state of the rewritten execution flag 42 is set to operate correctly, the execution flag 42 of the program is actually rewritten. In the fifth embodiment, the execution flag 42 of the cell is operated using the execution flag control means 171 in the tabular program. The operation of the execution flag 42 of the cell can be described by a script in the script field, and the execution flag 42 to be set in the cell together with the device and a string to be validated can also be described in the condition field. Do.

In the sixth embodiment, a character string is set in each cell and compared with the character string stored in the effective character string storage means 181. When the character string described in the cell and the character string stored in the valid character string storage means 181 match, the contents described in the cell are executed. If the character string described in the cell is not stored in the valid character string storage means 181, the contents described in the cell are not executed. If the character string is not set in the field for setting the execution flag 42 of the cell, the contents of the cell are executed regardless of the character string stored in the valid character string storage means 181.

In the seventh embodiment, the contents of the corresponding cell are displayed when the execution flag 42 is turned ON or when the valid string storage means 181 includes a character string such as a character string set in the execution flag 42. do. Other cells are not displayed. In addition, by displaying the corresponding cell and the other cells in different display colors, it is possible to display the cells which are made effective.

In the tabular program, it is also possible to specify the column unit and the row unit.

According to the third embodiment, it is possible to create replacement rows in row units or to create replacement columns in column units.

Further, according to the sixth embodiment, it is possible to set a valid character string to the execution flag 42 on a row basis or to set a valid character string on the execution flag 42 on a column basis. A row or column matching the character string stored in the valid character string storage means 181 is executed. Therefore, when describing a program that handles multiple varieties, it is possible to adjust the rows or columns to be executed by the effective character string storage means 181.

According to the present invention, by providing an execution flag that designates whether or not to execute the function block in the function block, and having a structure that can operate the execution flag even after converting the program created by the function block into the execution form, a part of the program can be Even if a change is made to a program such as a comment out, the program can be executed continuously without switching the execution flag again without changing the execution flag again, thereby improving the debug efficiency of the program.

Also, it is recommended to prompt the user to enter the correct execution flag setting by checking whether the program after the execution flag operation is a grammatically correct program, and if the grammatically incorrect program is correct, indicating to the user which part is not correct. Can be.

In addition, since only the program whose execution flag is valid among the programs can be displayed or the display colors of the valid and invalid programs can be displayed separately, the readability of the program can be ensured.
