Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention assigns addresses to the coils and contacts that are the constituent elements in a circuit diagram representing the constituent elements of sequence control executed by a PC (Programmable Controller).・This relates to an automatic PC address assignment/assignment device that can be assigned.

[Prior Art] Conventionally, when an electrical sequence control device is configured using a PC, a circuit diagram expressing the operation of the electrical sequence control device includes PC-specific addresses for the coils and contacts that are the components of the circuit. are assigned and assigned for practical use. Further, this address assignment/assignment must be unique to each component, and duplicate address assignment/assignment must be avoided.

[Problems to be Solved by the Invention] However, although the circuit diagram of an electrical sequence control device using a PC is extremely complex and has a large number of components, conventional address assignment and assignment is not possible using the circuit diagram. Moreover, the work was done manually, resulting in low work efficiency and frequent errors.

In addition, the range of addresses that can be assigned and assigned depending on the model of the PC used, and the address notation (numbers only or alphanumeric characters + numbers, octal display, decimal display, 16
Since the addresses assigned and assigned to coils with special functions such as digit display, etc.) and timers, counters, and arithmetic instructions are different, it is necessary to assign and assign addresses for each model of PC used, which is extremely complicated. I was getting used to the work.

Furthermore, when assigning and assigning addresses to the circuit drawings, there are cases where the addresses of specific coils or contacts are determined in advance. In other words, because the control panel has been manufactured or is in the process of being manufactured, addresses must be assigned and assigned as actually manufactured. Second, in order to connect and control multiple PCs in parallel operation, you must assign specific addresses to the coils and contacts that send signals to and receive signals from other PCs. If not. The third type is a contact that the PC itself has, such as a dead battery contact or a one-second pulse contact, and the address is fixed in advance. In order to allocate and assign such addresses, special processing must be performed on only a portion of the circuit drawing, which further reduces work efficiency.

The present invention was made in view of the above problems, and
Even if there is a coil or contact that requires a specific address assignment in a part of the circuit diagram on the PC's electrical sequence control, the circuit diagram for other components can be used without changing the specific address assignment. The purpose of this invention is to provide an excellent automatic PC address assignment/assignment device that can automatically assign/assign addresses without duplication.

[Means for Solving the Problems] The means constructed by the present invention to solve the above problems is as shown in the basic configuration diagram of FIG. It is equipped with a data storage means M1 and a circuit drawing data storage means M2 for storing circuit drawing data of the constituent elements on the sequence control performed by the PC, and automatically assigns addresses to the constituent elements of the circuit drawing data based on the specific data. In an automatic PC address assignment/assignment device that assigns and assigns PC addresses automatically, among the constituent elements of the circuit drawing data, a component to which an address arbitrarily set in advance is assigned/assigned, and an arbitrary PC address that stores the designated address. The designated data storage means M3 and the components stored in the arbitrarily designated data storage means M3 are assigned and given the designated addresses with priority, and while detecting and avoiding duplication with the designated addresses, the unique Data storage means M
The gist of the present invention is an automatic PC address assignment/assignment device comprising: an address assignment/assignment means M4 for assigning and assigning addresses to constituent elements of the drawing data based on the specific data of 1.

[Function] The unique data storage means M1 of the present invention stores unique data representing the functions of the PC to be used, that is, the type of input/output card, the number of input/output points per input/output card, the presence or absence of a counter, the type of latch, It stores data indicating the range of addresses that can be used for coils, timer, counter, latch coils, how to address contacts, types of arithmetic instructions, etc. Address allocation and
The assigning means executes the processing.

The circuit drawing data storage means M2 stores circuit drawings consisting of components (various coils and contacts) for sequence control executed by the PC. That is, it stores a circuit diagram showing all the components to which addresses need to be assigned and assigned.

The arbitrarily specified data storage means M3 means that among all the components stored in the circuit drawing data storage means M2, an address arbitrarily specified in advance is allocated and stored.
It stores the assigned components and the designated addresses. The specific address allocation/assignment stored in the arbitrarily specified data storage means M3 is absolute, and the address allocation/assignment means M4, which will be described later, processes this data with top priority.

The address allocation/assignment means M4 executes the following processing based on the data of the above-mentioned constituent means.

That is, among the components (various coils and contacts) stored in the circuit drawing data storage means M2, those whose addresses are specially designated are searched from the arbitrarily designated data storage means M3, and the components are stored according to the arbitrarily designated data. Executes address assignment/granting. Then, for the constituent elements other than the constituent elements to which the address assignment/assignment has been completed, the unique data storage means M1
Address allocation/assignment is executed in accordance with the unique data stored by the server and while avoiding duplication.

Hereinafter, in order to explain the present invention more specifically,
This will be explained in detail by giving examples.

[Example] Figure 2 is a block diagram of the automatic PC address assignment/assignment device according to this example. It is equipped with a CRT display 4 that visually displays results etc. to the operator. 6 is a magnetic disk device as a unique data storage means M1, a circuit diagram storage means M2, and an arbitrarily specified data storage means M3; and 8 is a printer for outputting hard copies of various processing results.
Each of these devices is controlled by a central processing unit 10 consisting of a computer that also functions as address assignment/assignment means M4.

Here, the unique data, circuit drawing data, and arbitrarily designated data stored in the magnetic disk device 6 are as follows.

First, unique data refers to matters that serve as standards for address assignment, such as which area addresses should be assigned to coils and contacts based on the PC's functions, and how to assign addresses to coils and contacts with special functions. be.

As shown in Figure 3, the circuit drawing data refers to the electrical sequence circuit diagram that the PC realizes expressed in the form of a ladder diagram, and the electrical equipment codes R2, D1, and D for each of its component coils and contacts.
It consists of 2,...

Additionally, the optionally specified data includes the electrical equipment code that requires specific address assignment as shown in Figure 4, and the address (0010, 0010,
4000, 4001, ...) as a pair of information.

Next, the operation of the PC address allocation/assignment device configured as described above and the processing flow resulting from the operation will be explained.

FIG. 5 schematically shows the entire process, and shows the relationship between the flow of the process and the constituent devices operated by the process. Here, the circuit drawing data as shown in FIG. 3 stored in the magnetic disk device 6 is inputted in advance by a data input device 12 such as an image reading device.

First, when an operator operates the keyboard 2 to instruct the central processing unit 10 to perform address assignment/assignment, the address assignment/assignment as shown in the flowchart of FIG.
Execution of the grant routine begins. Then, in step 100, the drawing number is input by the operator. A drawing number is a number assigned to a drawing to which an address is to be assigned/assigned from among a large number of circuit drawing data. When this number is input, the central processing unit 10 stores it in the magnetic disk device 6. The circuit drawing data with the input drawing number is selected from among the plurality of files of circuit drawing data, and access to the selected circuit drawing data is made possible from now on. If the circuit drawing data with the input drawing number does not exist in the magnetic disk device 6, the reason will be displayed on the CRT display 4 and the user will be prompted to input the drawing number again. In the next step 200, unique data such as model data of the PC to be used for this address assignment/assignment, and optionally specified data are input from the keyboard 2. This input data is then stored and memorized as PC-specific data and arbitrarily specified data in the magnetic disk device, and is used for subsequent processing. The details of the processing in step 200 are shown in the flowchart of FIG.

That is, when the processing of the central processing unit 10 moves to step 200, step 201 is executed first, and the
It is determined whether or not the unique data has been input, and if the input has not been completed, the keyboard 2 is pressed in step 202.
After prompting the user to input data, steps 203 and 204 are executed, and if the input has been completed, the process advances to step 205. In the case of circuit drawing data for which this work is being performed for the first time, this PC-specific data has not yet been input, so steps after step 202 will be executed. In step 203, it is determined by the operator's keyboard 2 input whether there is a coil or contact whose address needs to be specified arbitrarily in the circuit drawing data, and if necessary, step 204 is executed to update the data. Waits for the input, and if it is determined that it is not necessary, proceeds to the next step 250.

Therefore, step 205 is performed after the optionally specified data has been input in step 204, or when it is determined in step 203 that there is no need to input the optionally specified data, or if the PC-specific data has already been input in step 201, that is, it is targeted. This work is executed when this work is performed for the second time or later on the circuit drawing data. Here, the settings and input in each step above are shown.
It is determined by the operator's operation of the keyboard 2 whether or not the PC-specific data or arbitrarily designated data needs to be changed, and if there is no change, the entire process of this step 200 is terminated. If there is a change, the processes after step 206 are executed.

First, in step 206, it is determined whether the current change requires a change in PC-specific data or not.
If the PC-specific data is to be changed, the process advances to step 207, where the user is prompted to input the PC-specific data; otherwise, if arbitrary specified data is to be changed, the process advances to step 208, where the user is prompted to input that data, and the process returns to step 205.
The processing will then move on.

When the input of the PC-specific data and optionally specified data is completed in this way, the judgment in step 205 is NO, and the address is automatically assigned after step 300.
The granting process is executed.

The automatic address assignment/assignment process can be roughly divided into steps 300: coil list creation, error check A,
Step 400 address assignment and error check B,
Step 500 address assignment and error check C,
Processing is performed in the order of outputting the address allocation table and outputting the error list in step 600. The processing contents will be explained below in order of steps.

A flow diagram of step 300 is shown in FIG. first,
At step 301, the storage area of the coil list prepared in advance in the magnetic disk device 6 is cleared. FIG. 8 shows the structure of this coil list 14. The coil list 14 has an electrical equipment code column 14A,
It consists of a coil type field 14B, a page field 14C, a line field 14D, an address field 14E, and a check field 14F. Next, in step 302, one page of circuit drawing data is read out, and step 303 reads out one page of circuit drawing data.
Search for coils at . Then, a decision is made in step 304, and if there is no coil, the process proceeds to step 309, and if a coil is found, the decision in step 304 is made.
YES, and in the next step 305 it is checked whether the coil can be used with the PC to be used and whether the correct electrical equipment code has been attached. If this is correct, it is further checked in step 306 whether the electrical equipment code is already in the coil list, that is, whether the coils are duplicated. If the coils are not duplicated, in step 307, the input/output, dummy, timer,
After adding the type of counter latch, the page and line where the coil exists, and the electrical equipment code to the coil list, the process returns to step 303 to search for the next coil. If an error is determined in step 305 and step 306, an error check A is performed to check the content of the error in step 308.
This is temporarily stored in the error data file 16, and the process returns to step 303. The error data file 16 is a file for temporarily storing the contents of errors detected by the error check in order to output them as an error list to the printer 8 in step 600, which will be described later. It is also used for error checking, and becomes unnecessary once all processing is completed.

Next, if there are no more coils in that page, it is determined in step 309 whether all pages have been processed, and if not, the process returns to step 302 and proceeds to process the next page. When all pages are completed, the processing in step 300 is completed and the process proceeds to step 400.

A detailed flowchart of step 400 is shown in FIG.
In step 400, an address is assigned to each electrical equipment code in the coil list 14 of FIG. 8 created in step 300, and the value is entered in the address field 14E. First, in step 401, one electrical equipment code is extracted from the coil list, and in step 402
Search to see if the electrical equipment code is included in the optional address data. If it is optionally specified, proceed to YES in step 403, and proceed to step 404.
The specified address is set in the address column 14E, and in step 405, a value indicating that the address has been arbitrarily specified is set in the check column 14F. If not specified, step 403
The process proceeds to NO, and in step 406, an address is automatically assigned for each type of coil, and the address is set in the address column 14E. Automatic address assignment
Within the range of addresses that can be used for each type of coil specified in the PC-specific data, addresses are allocated sequentially starting from the lowest number. When one electrical equipment code has been assigned, it is determined in step 407 whether all assignments have been completed, and if not, the process returns to step 401 to repeat the process for the next electrical equipment code. When the judgment in step 407 is YES, the address column 14E of the coil list 17
If the address is filled in and the address is arbitrarily specified, a value indicating that the address is arbitrarily specified is set in the check field 14F. Furthermore, the range of addresses used in automatic allocation is also being determined. Then, as the next process, it is checked whether the arbitrarily specified address overlaps the range of automatically allocated addresses. First, in step 408, information for one electrical equipment code is extracted from the coil list 14, and in step 409, it is determined from the value in the check column 14F whether it has been arbitrarily designated. If it is arbitrarily specified, it is determined in step 410 whether the address overlaps with the automatically assigned address range, and if it is, in step 411 the information is checked as an error and checked for error. It is stored in the error data file 16 as .
In step 412, the check field 14F is cleared again for the subsequent step 500. When the check for one item is completed, it is determined in step 413 whether all the checks have been completed, and if not, the process returns to step 408 and the check is repeated. After checking all electrical equipment codes, the step
Step 400 ends and the next step 500 begins.

A detailed flowchart of step 500 is shown in FIG.
In step 500, the circuit drawing data is read out again and a process of assigning assigned addresses to all the coils and contacts therein is performed. First step 501
One page of circuit drawing data is read out in step 502, and a coil or contact is searched from therein in step 502. If a coil or contact is found, the process advances to YES in step 503, and in step 504 it is determined whether it is a coil or a contact. If it is not a contact, proceed to step 508; if it is a contact, proceed to step 508.
If the contact is a momentary contact in 505, the PC used
Check to see if it can be used with the device and if it has the correct electrical equipment code. If this is correct, it is further checked in step 506 whether the electrical equipment code is in the coil list. If it is in the coil list, a value indicating that there is a contact with that electrical equipment code is set in the check field 14F, and in step 508, the address assigned to the address field 14E is read out and the circuit drawing data is read out. Assign it to the address field according to the type of contact (ordinary contact, instantaneous contact, etc.). If the contact is not included in the coil list in step 506, a search is made in step 509 to see if the electrical equipment code is included in the address arbitrary designation data. Step if optional
The process advances to YES in step 510, and the specified address is assigned in step 511 according to the type of contact. If an error is determined in step 505, or if the coil is not in the coil list in step 506, error information is written in step 512. Here, even if an address is assigned in step 511, error information is written in the error list in order to inform the operator that the coil corresponding to that contact does not exist in the circuit drawing data. This is to do so. On the other hand, if it is a coil at step 504, the check has already been completed at step 504.
300, so search for the corresponding electrical equipment code in the coil list and step through the address assigned to the address field 14E.
Granted with 508. Once the address has been assigned for one coil or contact, repeat the steps to search for the next coil or contact.
Return to 502. If the coil or contact disappears in step 503, addressing for that one page has been completed, and therefore, in step 513, the circuit diagram data for that one page is re-stored in the original location of the magnetic disk device 6. Then, in step 514, it is determined whether processing has been completed for all pages of circuit drawing data, and if it has not been completed, the process returns to step 501 and proceeds to address assignment processing for the next page. After completing all pages, check column 14 of coil list 14.
F contains a value representing only the electric equipment code in which a contact exists, and the next process is to check for coils that do not have a corresponding contact. First, in step 515, information for one electrical equipment code is extracted from the coil list, and in step 516, it is determined from the value in the check field 14F whether a corresponding contact exists. If the corresponding contact does not exist, the information is written as an error check C error in step 517. step 518
At step 515, it is determined whether or not all electrical equipment codes have been checked. If not, the process returns to step 515 and the check is repeated. Step 500 after checking all electrical equipment codes
ends.

In step 600, which is executed last, the information in the coil list 14 is sent to the printer 8 as an address assignment table in the form of an easy-to-read table in the order of addresses, along with annotations added to the positions of the coils in the circuit drawing data. Output. Furthermore, error data file 16
The error information stored therein is rearranged in page and line order and output as an error list to the printer 8, thereby completing the entire process of automatic address assignment and assignment.

As explained above, the automatic PC address assignment/assignment device of this embodiment is complicated and prone to errors.
Not only can PC addresses be automatically assigned and assigned, but the predetermined addresses for assignment and assignment are stored as optionally specified data, which requires parallel operation of the control panel and PC being manufactured. This makes it an excellent device that can be used for any purpose. Furthermore, special circuit components such as contacts that do not have a corresponding coil in the circuit drawing can be printed in hard copy by the printer 8 at the end, which also has the effect of improving the efficiency of related work. be.

[Effects of the Invention] As described above in detail with reference to embodiments, the automatic PC address assignment/assignment device of the present invention includes a unique data storage means for storing unique data representing the functions of a PC, and a circuit drawing data storage means for storing circuit drawing data of components on sequence control to be performed, and automatically assigning and assigning addresses to the components of the circuit drawing data based on the unique data. In the allocation/assignment device, among the constituent elements of the circuit drawing data, a component to which an address arbitrarily designated in advance is assigned/assigned, an arbitrarily designated data storage means for storing the designated address, and the arbitrarily designated data. For the components stored in the storage means, the above specified address is assigned with priority.
and address assignment/assignment means for assigning and assigning addresses to constituent elements of the drawing data based on the unique data of the unique data storage means while detecting and avoiding duplication with the designated address. This is a characteristic feature.

Therefore, the assignment and assignment of PC addresses, which has traditionally been done manually, resulting in low work efficiency and many errors, can be automatically executed, resulting in a significant improvement in efficiency.

Furthermore, among the components in the circuit drawing, address assignment/assignment is performed with priority for components stored as arbitrarily designated data in the arbitrarily designated data storage means, and a designated address designated in advance is assigned.・Since the address is assigned, if there are special components such as components whose addresses are specified in advance or contacts that do not have corresponding coils in the circuit drawing, these components can be stored as arbitrary specified data along with the specified address. By doing so, it is possible to allocate and assign addresses without changing the addresses of these components.

In addition, since all data is stored in the storage means, there is no need to re-input arbitrary specified data even when address assignment/assignment processing is required again due to circuit modification etc. This has great effects, such as the ability to automatically create a PC program from circuit drawing data to which an address has been assigned and write it onto a cassette magnetic tape.
