Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a PC (Programmable Sequence
This invention relates to a device that automatically assigns addresses to coils and contacts in circuit drawings for controllers, and assigns these addresses to the drawings.

[Prior art] Generally, coils and contacts in PC circuit drawings are
The work of assigning and assigning PC addresses should be done so that they do not overlap for all the coils that appear in the drawing.
This involves assigning addresses to the PC and then assigning (writing) the assigned addresses to all contacts and coils in the drawing.

Traditionally, this work was done manually.

[Problems to be solved by the invention] However, the range of addresses that can be used and the address notation (numbers only or alphanumeric characters only, alphanumeric characters only, octal notation, decimal notation, 16 decimal notation, etc.)
Since the method of assigning addresses to coils with special functions such as timers, counters, and calculation instructions differs, it is necessary to assign addresses according to the model used, which makes the work complicated and increases the risk of mistakes. The frequency of occurrence was also relatively high.

The present invention aims to solve the above points. That is, an object of the present invention is to automatically allocate and assign addresses according to the model used, thereby simplifying the work and suppressing the occurrence of work errors.

[Means for Solving the Problems] Therefore, the present invention, as shown in _FIG .
A device that automatically assigns and assigns addresses 4000, 4000, and 0100 to C ₂ , and has model name data D that represents the model name of the PC and function data E that represents the model-specific contents of the model.
When the first data file G in which the model data F for each PC is registered and the drawing data H before address assignment are input, and the model name of the PC to be used is specified, the above first data A second data file I into which model data F of the PC is input from file G.
Then, an address is assigned to each of the coils and contacts based on the model data F of the second data file I, and this address is added to the drawing data H of the second data file I before the address is assigned. A processing device J;

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

Figure 2 shows the automatic PC address assignment and
1 shows an embodiment of the configuration of the applicator.

In the figure, 1 is a keyboard, 2 is a CRT display, 3 is a processing device, 4 is a magnetic disk device, and 5 is a printer.

Next, an example of the operation of this apparatus and the flow of work by an operator will be explained based on the flowchart shown in FIG.

After setting a first magnetic file as a first data file and a plurality of second magnetic files as second data files in the magnetic disk device 4, first, in step 1, The operator performs an operation of inputting a drawing number, that is, inputting, via the keyboard 1, a drawing number previously assigned to a PC circuit drawing to which an address is to be assigned/assigned. When this drawing number is input, the processing device 3 stores in advance the drawing data of the PC circuit drawing designated by the input drawing number from among the second magnetic files, and stores the drawing data in the magnetic file (Fig. 3). (corresponding to the drawing/model data file 6 in Figure 1) to enable access to this drawing/model data file 6. The drawing data in this drawing/model data file 6 can be used to input electrical equipment codes and annotations to other data input devices (reference numeral 7 in Figure 3) for all coils and contacts of the designed PC circuit. This is the data obtained by inputting the data (representative), and corresponds to the drawing data before address assignment as referred to in the present invention.

Next, in step 2, the processing device 3 determines whether or not the model-in-use data has already been input into the drawing/model-in-use data file 6, based on the model-in-use data in the selected drawing/model-in-use data file 6. to judge. Here, the model data used is
This is data related to a PC that performs sequence control expressed in a PC circuit diagram, including model name data that indicates the model name, and model data that indicates the function specific to the model, such as input/output card type, input/output Number of input/output points per card, presence or absence of a counter,
It consists of data indicating the type of latch, the address range that can be used for the coil, the timer/counter/latch coil, how to address contacts, the type of arithmetic instruction, etc.

Since the above-mentioned machine type data has not yet been input at the start of this work, in step 3, the processing device 3 inputs the first magnetic file (corresponding to the machine type data file 8 in FIG. 3). The contents of the model data are displayed on the screen of the CRT display 2, and the operator is made to judge whether or not the model data to be used has already been registered in the model data file 8. Here, the model data file 8 has a data structure as conceptually shown in FIG.
In FIG. 5, 8a is a list of registered model names, and model name data 8 representing model names A, B, C, etc.
c, and a pointer 8d indicating the address of function data 8b representing the functions corresponding to model names A, B, and C, respectively.

If the operator determines that the desired model data is not registered, in step 4,
The operator operates the keyboard 1 to input data on the model to be used. The processing device 3 performs a process of registering the input model data in the model data file 8 in addition to other model data that has already been registered. Then, proceed to step 5.

On the other hand, if the operator determines that the desired model data has already been registered, the process proceeds to step 5 without passing through step 4.

In step 5, the operator operates the keyboard 1 to input the name of the model to be used. When the name of the model used is input, the processing device 3 searches the model data file 8 for model data that matches the name of the model used, and performs a process of inputting this model data into the drawing/model data file 6. .

Next, in step 6, the operator judges whether or not to change the model to be used in order to determine whether the model to be used is appropriate.

If it is determined that the model to be used should be changed, the process goes through steps 3 to 5 described above in order, and then returns to step 6.

If it is determined that there is no need to change the model used, an instruction is given via the keyboard 1 to automatically assign and assign addresses.

Upon receiving this instruction, the processing device 3 proceeds to step 7.
Then, addresses are assigned to all coils and contacts based on the drawing data and model data in the drawing/model data file 6, and the process of assigning these addresses to the drawing data, error checking, and address assignment table are performed. and outputting the error list to the printer 5. Details of this processing will be described later with reference to FIG. Then, this work is completed.

After that, when the drawing number corresponding to the model data entered into the drawing/model data file 6 is entered in the above process, the judgment result in step 2 will be ``YES''.
Steps 3, 4, and 5 are not executed, and the process moves directly from step 2 to step 6. Note that when the drawing with this drawing number is modified, the address assignment/assignment is redone.

FIG. 4 shows a flowchart showing the processing contents in step 7 above. This step 7 is roughly divided into step 7-1, step 7-2, step 7-3, and step 7-4.

In step 7-1, a coil list creation process and an error check are performed. The coil list creation process reads the drawing data in the drawing/model data file 6, selects coils by function such as input/output, auxiliary coil, timer, counter, latch, etc., and corresponds to the electrical equipment code. and make a list. In addition, error checks are performed to determine whether the equipment code is correctly attached to the coil, and whether the use of coils with functions such as counters and latches is correct (for example, whether a latch coil appears in the drawing even though the PC does not have a latch function). etc.). The latter determination is made based on the contents of the model data. Errors discovered by the check are temporarily stored in an error data file 9 in order to output the contents to a printer later. Note that this error storage also applies to error checking, which will be described later.

Next, in step 7-2, addresses are assigned based on the coil list. The address to be allocated at this time is based on the information on the usable address range in the model data. Also, as an error check, it is checked whether the number of coils is too large and exceeds the usable address range. The assigned addresses are recorded in the address column of the coil list, and the coil list is in the form of a correspondence table between the electrical equipment code of the coil and the address.

When the process of step 7-2 is completed, a process of assigning an address to the drawing is performed in step 7-3. Here, read the drawing data again, pick out all the coils and contacts, search the coil list for the electrical equipment code attached to it, and add the address assigned to that electrical equipment code in the drawing. In other words, add it to the drawing data. At this time, addresses for timers, counters, latches, arithmetic instructions, etc. are assigned in accordance with rules based on the model data used. Also, as an error check, check whether instantaneous contacts or arithmetic instructions for timers, counters, and latches that cannot be used with the model are used in the drawing, whether the electrical equipment code for the contact is correctly attached, and whether the electrical equipment that is the same as the contact is used. It is checked whether there is indeed a coil with the code, and whether there is any coil for which no contact appears after all the connections have been applied.

Finally, in step 7-4, an address allocation table is printed based on the final drawing data in the drawing/model data file 6, and an error list is printed based on the contents of the errors found in the error data file 9. 5 and completes the address assignment/assignment.

As explained above, the only work required by the operator to assign and assign addresses to drawings is to register the model of the PC to be used and to specify the model name (however, the registration work only needs to be done when the PC is used for the first time). be done.

As another example, in the above example, the order of steps 3, 4, and 5 in FIG. The processing device 3 may be made to determine whether the model is registered, and if the model is not registered, the function of model registration may be automatically selected and executed.

[Effects of the Invention] As described above, according to the present invention, the work of assigning and assigning addresses to drawings is limited to the work of registering the model to be used and the work of specifying the model name (however, the registration work is done only when the PC
Only when used for the first time. ), it is possible to reduce the huge amount of man-hours that were previously required, and automation can reduce work errors.

In addition, according to the above-described embodiment, since an error check is also performed, it is possible to easily discover simple mistakes in drawings.
