JPS63128431A - Producing device for process language string collation type flow chart - Google Patents

Abstract

PURPOSE:To enable even a worker working at a job site to easily carry out a debugging job, etc., based on a flow chart by adding the collating information on the corresponding relation with a process language train to the position of each flow chart symbol contained in a produced flow chart. CONSTITUTION:An absolute address AD (with a jumping destination label L if needed) of the corresponding mnemonic code is added to the position of each flow chart symbol K of the flow chart information in the form of the collating information. Thus a flow chart is compiled. Then the absolute address of the mnemonic code concerning each symbol K can be immediately grasped since the address AD and the label L corresponding to each other on a program list are added to each symbol K in the form of the collating information. Thus it is possible to directly understand a flow of control actions by the flow chart.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to an apparatus for creating a processing language column-contrastive flowchart suitable for debugging work and the like.

(Summary of the Invention) In the present invention, in a data processing device that performs programming using a flowchart, such as a flowchart-based programmable controller, the correspondence relationship between an input flowchart and a processing old word string of the data processing device is established. It creates a flowchart that can be easily checked.

(Prior Art and its Problems) As shown in FIG. 7, programming in a flowchart type programmable controller is generally performed in the following steps.

First, use a graphic programming console unit (hereinafter referred to as GPC) or a normal personal computer to draw flowchart symbols such as processing step symbols and two-branch symbols at the cursor position on the screen while running the editor software. to create flowchart information. This flowchart information is written as a pair of each flowchart symbol and its XY coordinates.

Next, this flowchart information is converted into a binary sequence corresponding to the processing language sequence of the programmable controller using predetermined conversion software.

This binary sequence is then downloaded into the program memory of a field-located programmable controller to complete programming.

By the way, when debugging this type of programmable controller, for example, prepare a hard copy of the originally created flowchart and program list (mnemonics table), and if a problem is found on the flowchart, For example, by searching for the relevant 21 Monik in the program list, inputting its storage address from the on-site programming tool, the corresponding 21 Monik is read out on the display of the tool, and checked or corrected. Repeat the work.

However, it is not always easy for on-site workers to understand the correspondence between problem locations in the flowchart and twenty-one monitors on the program list. This is because in the case of a ladder diagram programmable controller, the order in which each symbol (relay, contact, etc.) on the ladder diagram is written almost corresponds to the order in which the secondary symbols are written in the program list. While it is relatively easy to understand the correspondence relationship between flowcharts, programmable controllers that use flowcharts have flowchart symbols such as branches and returns in the middle, which makes it difficult to understand the order in which the flowchart symbols are written on the flowchart. The order in which the two-monics are listed on the program list is often not unambiguously determined, and even if workers at this type of site are angry at ladder diagrams, they are usually unfamiliar with flow diagrams. This makes it difficult to understand the correspondence between the flow chart and the program list.

(Objective of the Invention) The object of the present invention is to easily grasp the correspondence between flowcharts and processing language strings in a data processing device that performs programming using flowcharts, such as the flowchart-based programmable controller described above. An object of the present invention is to provide a processing language string-contrastive flowchart creation device.

(Structure and Effects of the Invention) In order to achieve the above object, the present invention includes a flowchart input means for inputting flowchart information corresponding to desired job content, and a flowchart input means for inputting flowchart information corresponding to desired work content, and a flowchart input means for decoding the inputted flowchart information to input a specific data processing device. a flowchart editing means for converting into a processing language string and adding collation information indicating a correspondence between the obtained processing language string and the inputted flowchart to each flowchart symbol position in the inputted flowchart information; and each flowchart symbol. The present invention is characterized by comprising: flowchart output means for performing flowchart drawing processing based on flowchart information in which collation information is added to the position.

According to such a configuration, collation information indicating the correspondence with the processing language string is attached to each flowchart symbol position in the created flowchart, so that the correspondence between the two can be clearly understood. The on-site work Q can also easily perform debugging using flowcharts.

(Description of Embodiments) FIG. 1 is a perspective view showing the appearance of a processing language string comparison flowchart creation device (hereinafter referred to as creation device) 1 according to the present invention.

As shown in the figure, the creation device 1 includes a printer 11°CRT
Display 12. It is composed of a keyboard 13, a personal computer 14, and the like.

The personal computer 14 constituting the creation device 1 is equipped with a conventionally known editor for creating flowchart information based on operations on the keyboard 13, and is also equipped with a control program shown in FIG. 3, particularly in relation to the present invention. Newly prepared.

That is, when a flowchart as shown in FIG. 4 is drawn on the screen of the CRT display 12 using the keyboard 13, flowchart information is created and stored by the action of a known editor (see FIG. 2).

As is well known, this flowchart information is written by sequentially arranging each flowchart symbol and its XY coordinate as a pair.

The created flowchart information is then processed according to the flowchart of FIG. 3, and finally the two-monic column contrast type flowchart of the present invention is created.

That is, when the program starts at 1 in FIG. 3, first, as an initial process, the coordinate registers
Label register N and absolute address register ADR are cleared (step 301).

Next, while sequentially searching each X and Y coordinate in the flowchart information (step 305), the flowchart description @K of the coordinate position is
is read out (step 302).

Then, when each flowchart symbol K is read out, whether the flowchart symbol K is a symbol that generates a jump destination label (step 3
03) Or a symbol that generates a 21 Monik code (
The determination in step 304) is performed each time.

Here, if it is determined that the symbol generates a 21-monic code (Yes in step 304), the flow chart symbol K is converted into a 21-monic code according to a known algorithm (step 307), and the obtained 2-monic code is converted into a 2-monic code. The X and Y coordinates of @ and the absolute address ADH where the 21 Monik is stored are temporarily stored as one set (step 308
), the absolute address ADR is updated by +1 (step 309), and the above operations are repeated.

On the other hand, if it is determined that the flowchart symbol generates a jump destination label (Yes at step 303), the jump destination label r
After generating LBL NJ (step 310), the label register N is incremented by +1 each time (step 31).
1) Regarding the jump destination label, in the same manner as described above, the corresponding X, Y coordinates and the storage absolute address ADR of the jump destination label are temporarily stored as a set (step 308);
The absolute address ADR is updated by +1 (step 309) and the above operations are repeated.

While repeating the above, when the search is completed to the predetermined end of the X, Y coordinates (step 306 tl!), as shown in FIG. is completed.

Note that FIG. 5 shows a state in which the program list has been printed out, and therefore, the storage of the X and Y coordinates for each binary, which is related to the present invention, is not shown.

In this way, when the conversion from the flowchart information to the two-monitor sequence is completed, in step 308, based on the temporarily stored X, Y coordinates and the previously created flowchart information, The flowchart is edited by adding the absolute address ADR (if necessary, the jump destination label L) of the corresponding two-monitor as collation information to the position of each flowchart symbol (step 312, see FIG. 2).

Next, based on the new flowchart information that has been edited, the printer 11 or CR7 display 12 is driven to perform drawing processing, thereby creating a two-monitor row contrast type flowchart as shown in FIG. (Step 313).

As is clear from FIG. 6, each flowchart symbol K of the flowchart obtained from this creation device 1 has a corresponding absolute address AD and jump destination label L on the program list.
is added as verification information, so based on these, the absolute address of the binary associated with each flowchart @K can be immediately grasped, and therefore the flow of control operations can be intuitively understood by the flowchart. At the same time, the correspondence between this flowchart and the two-monitor sequence can be clearly understood, which is extremely convenient for debugging operations by field workers and the like.

In addition, in the case of this embodiment, since the jump destination label L is also displayed, it is possible to visually understand the relationship with the 21 Monique, which cannot be seen in a mere flow chart, and the 2-
It is possible to more easily understand the correspondence with the monitor string.

In addition, in the above embodiment, the programmable
Although the present invention has been described in the case where it is applied to a controller, the application of the present invention is not limited thereto, and can be widely applied to various data processing devices that perform programming using flowcharts.

Moreover, although the flowchart information is input by operating the keyboard 13 in the above example, it is of course possible to read the flowchart information directly from a floppy disk or the like.
