Abstract

PURPOSE:To reduce the manhour of programming, and simultaneously, to improve the quality of programming by inserting a delimiter symbol of a character or a symbol between plural information in a comment to plural inputs and outputs of a programmable controller. CONSTITUTION:An input comment is delimited and prescribed by using a delimiter symbol at every symbol and character, and also, its sequence and position, etc., are determined. That is, a comment input means 4 executes setting of an input and an output, editing of a comment part at the time of editing, segmentation, etc., a comment analyzing 1 divides the delimiter symbol, character information, etc., of the comment, a comment storage means 2 stores these comments in a comment memory 3, and a comment retrieving means 5 retrieves the names, operation and state information of every comment without overlooking them. In such a way, input and output items at the time of debugging a program can be confirmed easily and clearly without overlooking them.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input method for comment input in programming of a programmable controller that controls a mechanical device.

[Prior Art] In programming a conventional programmable controller, it was necessary to define input and output in addition to writing the program. The inputs and outputs of this programmable controller are numerically predefined within the controller by alphanumeric input/output numbers such as YOOI and X0O2, similar to computer inputs and outputs and memory addressing.

In the simplest case, a program is written using these input/output numbers, but comments are usually used to indicate the names and operations of input/output environments such as input/output devices to help designers understand.

The method for processing the above comment is JP-A-63-1723.
As described in Publication No. 03, a program buffer is edited using a program display editing function, a comment buffer is edited using a comment display editing function, and a program with comments is displayed.

[Problems to be Solved by the Invention] The conventional method described above has a problem in that the number of comments increases dramatically as the scale of the mechanical device to be controlled increases.

Further, although the above comments contain a lot of information regarding mechanical equipment, they are merely used superficially as memorandum data accompanying input/output.

SUMMARY OF THE INVENTION An object of the present invention is to provide a comment input method and a programming device for a program controller that utilize comments having information on the mechanical device to be controlled to reduce programming man-hours and downtime of the mechanical device.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention divides and describes input comments for each symbol and character using a delimiter, and further determines the order, position, etc. of the input comments.

Furthermore, a comment analysis means for classifying the delimiters, character information, etc. of the above-mentioned comments, a comment storage means for storing these contents, and a comment search means for searching and displaying the above-mentioned stored contents for each item using a search table. [Function] In the comment input method of the present invention configured as described above, the comment input means is configured to input/output settings The comment section is edited, cut out, etc. during editing, the comment analysis means separates the comment delimiters, character information, etc., the comment storage means stores these contents in the comment memory, and the comment search means separates the comments for each comment. Search for names, operations, and status information without overlooking them.

[Example] FIG. 1 is an explanatory diagram of the operation of one embodiment of the present invention.

With the configuration shown in FIG. 1, comments are input and input/output information is stored according to the model of the controlled object (mechanical device).

The comment input means 4 inputs the contents of each comment in the order of input/output numbers. At this time, a delimiter is used to distinguish the type of content, and in this embodiment, as an example, a colon (colon) is used as the delimiter. Also, the order in which the comments are written is the name, operation, and status of the input/output device. The above delimiters and the order in which the comment contents are written can be changed as necessary.

To explain an example of the above comment, for example, when the output corresponding to the address number YOOI describes the ascent of a drill, the next word after YOOI is ``Trill: Ascent Pattern'' as described in the comment input/output means 4. In addition, if the input/output number X0O2 indicates that the drill should rise to the upper limit and stop, then '''Drill:
Rise: Completed'' is written as ``Drill u'' above.
For example, a term such as ``P+rise'' may be changed to ``drill movement tT.
, I+rises''.In this example, the first term of the comment content describes the attribute of the input/output, and the second term describes the operation. do.

In FIG. 1, comment analysis means 1 identifies the delimiter (:) of an input comment and classifies the contents of the corresponding section. Next, the comment storage means 2 stores the contents of each section of the comment in the comment memory 3 in correspondence with the input/output numbers, as shown in FIG. As a result, it becomes possible to clearly categorize and organize each piece of information within a comment.

Figure 2 shows an example of storing a single comment such as "Y 001" and "Drill" rising.Since "Drill" has 3 characters, add 3 in front of it, and similarly, "Rise" Add the two characters 2 in front of it, and then add the total number of characters 7, including the above 3 and 2, in front of it, store this as one comment content in the data area of comment memory 3, and write it at the beginning. Address number YOO3 is stored in the address management area.

The comment search means 5 searches various lists.

FIG. 3 is a diagram showing an example of the above search. That is, the second term related to the input/output attribute (first term) input by the user is searched, and if there is a third term, this is displayed at the end.

In Figure 3, if drill is specified in the first term, YOO1 and
0O2 is searched, YOOI raises the drill, and X
002 indicates that a series of operations in which the raising of the drill is completed has been retrieved.

FIG. 4 shows another example of the above search display. In this way, in this embodiment, the first term is grouped for each common input/output attribute and related comment contents are displayed sequentially, and the third term is executed after the second term, so the last term is so that it is placed in

Next, a search performed when a mechanical device breaks down will be explained using FIG. 5. With conventional methods using program lists and cross-referencing of input/output programs, the effective order of programs can be grasped, but the interrelationships between inputs and outputs are known only to the designer of the mechanical system to be controlled, and are not known to others. were often difficult to analyze.

Additionally, each commenter often uses different expressions (terms) for the same action, and some of the terms that have already been used are overlooked when searching, making it impossible to search for the comment you want. There was a problem.

In order to solve the problem of overlooked comments, the present invention includes a search table that stores all of the term information that may be used in the comment search means 5, and uses this as a dictionary to Inquire and classify the contents of each section.

so that it can be displayed. For example, "raise" in the operation (second term) of the above drill (item 1) is "raise".
, and "retreat", and "descend" is also a synonym for "lower" and "advance", so when searching for "trill" or "drill up" or "downward pa", use Figure 5. As shown, the terminology information in the comment search means 5 is searched and all synonyms are extracted and displayed to ensure that no related comment is overlooked.

The operation of the present invention described above is basically as shown in FIG. This can be achieved by performing analysis processing and determining, setting characters, symbols, etc. in the buffer 11 according to the above determination results, and storing them in the comment storage means 2 in units of comments.

As shown in FIG. 1, the buffer 41 is stored in the comment input means 4, and the buffer 11 is stored in the comment analysis means 1.
located within.

FIG. 7 is a flowchart illustrating the operation of the present invention in more detail.

In step S1, one character input from the keyboard is captured,
This is stored in the buffer 41 in the comment input means 4 in step S2.

In the next step S3, if the above-mentioned one character is an end symbol such as a carriage return (CR), it is determined that the comment input has been completed for one time, and the process returns to step S1.It is determined that the comment input has been completed for one time, and the process returns to step S1. , move on to input the next comment.

In step S4, the comment in the buffer 41 is cut off one character at a time, and in the next step S5, if this is an end symbol, the process moves to step Sll and the number of characters of the entire comment is set in the buffer 11 in the comment analysis means 1. Then, in the next step S12, the contents of the buffer 11 are transferred to the comment storage means 2, and the process ends.

In step S5, if the character sent from step S4 is not an end symbol, it is determined in the next step S6 whether or not this is a delimiter, and if this is not a delimiter, in step S9 this character is stored in the comment analysis means 1. Set it in the buffer 11 of Then, in the next step SIO, the number of characters in the term is counted up by one, and the process returns to step S4.

If the delimiter is determined in step S6, the number of characters in the term corresponding to the delimiter is set in the buffer 11 in the comment analysis means 1 in the next step S7. Then, in the next step S8, in order to analyze the subsequent terms in the same way, the process moves to the next term and returns to step 4.

In FIG. 7 above, the analysis proceeded while capturing the comment character by character, but as an alternative method, the entire comment separated by delimiters may be captured into the buffer 41 in the comment input means 4 in step S4. From now on, you can also analyze each comment in the same way.

[Effects of the Invention] According to the present invention, input/output items can be easily and clearly confirmed during program debugging without being overlooked, thereby reducing programming man-hours and improving programming quality at the same time. can.

Similarly, it is possible to shorten the time required to analyze the cause and take countermeasures when a failure occurs in a mechanical device.
