Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network integrated control device and a program generator control device, and more particularly to a plurality of control devices such as a sequencer for sequence control of industrial robots and NC machine tools used in FA factories. The present invention relates to a network integrated control device that can be controlled in an integrated manner, and a program generator control device for combining a plurality of programs of these control devices to manufacture a new program.

[0002]

2. Description of the Related Art A production line in an FA factory comprises a plurality of processes. For example, an automobile assembly line includes a door mounting process, a tire mounting process and the like. In an FA factory having such a line, different types of industrial robots and NC machine tools are installed for each process, and actuators for operating these are controlled by various control devices such as a sequencer.

In the current FA factory, in order to produce high quality products with high production efficiency and safely, even if control devices used in each process are mixed with those of different manufacturers, In recent years, it has been requested to select the one that exhibits the best performance and to collectively control a plurality of control devices.

However, since the control device of each maker is designed on the basis of the operation of a single unit, there is no technology for connecting and controlling the control devices of different makers. Therefore, even if the automation of each process can be achieved by using the control devices of each manufacturer in a mixed manner, it is not possible to realize the unified centralized management of all processes.

Therefore, recently, a network system that enables centralized management of all processes by allowing mutual exchange of data between control devices of respective manufacturers has been studied.

However, if the manufacturers of the control devices are different, the data formats of the control devices, how to make signals, command words, etc. are different, and the data formats and the like of the same manufacturer are often different. Therefore, if it is attempted to create a network system in such a situation, in a network system composed of a plurality of control devices of different models as described above, it is not necessary to create converter means that enables the data conversion between the control devices. must not. However, in a network system consisting of a large number of control devices, the combination of control devices trying to exchange the data is a geometric series number, and it is very difficult to create a converter program that covers all of them. there were. Then, there is a problem that more converters must be created each time a new control device is created.

Due to the above reasons, it is practically impossible to realize the network system. Therefore, in the conventional FA factory, in order to give priority to centrally controlling a plurality of control devices, there are many examples in which the control devices in each process are all of the same model made by the same manufacturer. However, the control device that exhibits the best performance in each process is often of a different model, and using a control device of the same model in all processes results in production efficiency not being able to use a control device with good performance. There was a problem of being greatly damaged.

In addition, conventionally, for example, in such an FA factory, it is necessary to newly create a sequencer program for controlling the operation of these processes due to addition of new processes or modification of existing processes. May come.

In this case, it is convenient to create a new program by combining programs of a plurality of sequencers for controlling a predetermined function in a certain process, as compared with creating a program from the beginning. This is being attempted.

However, since the work for combining a plurality of programs to obtain a normally operating new program is considerably complicated and takes a long time, such an attempt is almost unsuccessful. It was the current situation.

It is an object of the present invention to provide a network integrated control device capable of controlling these control devices in a centralized manner even if the control devices of different models are used. Another object of the present invention is to provide a program generator control device that can combine a plurality of programs and easily create a new program.

[0012]

SUMMARY OF THE INVENTION In order to achieve such an object, the present invention provides a standard file in which a plurality of control devices, a common network connected to each control device, and data recorded in each control device are accumulated.

It is a program generator control device.

This program generator controller is
It has a fixing means for fixing a common address commonly used by a plurality of programs. This fixing means has an instruction file for instructing the type of common address to be fixed as a common address, and fixes the common address based on this instruction file.

Further, the program generator control device has a shift means for shifting a unique address which is used in duplicate among a plurality of programs. This shift means has an instruction file for instructing an unused address to which the unique address should be shifted, and shifts the unique address based on this instruction file. A sequencer can be exemplified as the control device.

When the invention of the program generator is applied to the network integrated control device, the invention of the network integrated control device further symbolizes and displays a plurality of programs recorded in the program file, and arranges them in a desired order. In addition, a configuration for combining programs based on this arrangement is provided.

According to the present invention, a standard file is prepared, and data can be exchanged between control devices of different models via this standard file. In this case, the conversion means that enables data exchange between the standard file and the control device may be prepared by the number of standard file types determined by the number of control device models. Since it is not necessary to prepare a huge number of data conversion means, a network integrated control device for centrally managing a plurality of control devices can be realized easily and surely.

Further, according to the present invention, one program can be grasped as a component on the screen by symbolizing the program. Therefore, the programs can be easily combined by a method of assembling desired parts in a predetermined order on the screen. As a result, it is possible to create a program in which the functions of the programs are combined. Moreover, even if multiple programs use duplicate addresses, this address can be shifted to an unused address to eliminate the address overlap, so that the created new program operates normally. You can

Here, the duplicate addresses are fixed as a common address, and the shift destinations as the unique addresses are stored as an instruction file, so that the matching of the duplicate addresses is executed at one time based on the instruction file. You can As a result, it is possible to perform the matching operation of the duplicated addresses in a short time. Therefore, the creation of the program is completed in a short time and easily.

Each standard file and each sequencer are connected by an I / O circuit 11 via the network circuit 10. Therefore, the data of each sequencer is
The standard files can be loaded (uploaded) through the network circuit 10 and the I / O circuit 11, and data can be loaded from the comment file 12A, the device name file 12B, the program file 12C, and the device code file 12E. , Load to each sequencer via I / O circuit 11 (download)

Then, the central processing computer 16
Can read the contents of each standard file via the I / O circuit 14 and display the contents on the display device 18, and also comment file 12A, device name file 1
2B, program file 12C, device code file 1
The contents of 2E can be updated and the newly created data can be loaded into each of these files. still,
The CRT device 18 can display the contents of the desired standard file or files. Then, data of a desired single or plural sequencers can be uploaded to each standard file. The display device 18 can also display the contents of the program file as a ladder diagram (a diagram of the contents of the program).

The central processing computer 16 also has a function as a program generator that combines a plurality of programs of each sequencer to create a new program. In order to achieve this function, the central processing computer symbolizes (designs) each program, displays the program as so-called parts on the display device 18 (symbol display means), and arranges these parts on the screen. (Arrangement means), and combining these (coupling means)

It has a database for recording symbols (designs).

Next, the operation of this embodiment will be described according to the operation procedure of the central processing computer 16. Figure 2
Is a schematic flowchart showing the operation procedure thereof. When the central processing computer is activated, an initial menu screen is displayed on the display device 18 in step 200. The function of the central processing computer 16 is to display the contents of one or more desired files of the standard files, or to select the desired contents of the comment file 12A, the device name file 12B, the program file 12C and the device code file 12E. "Display / correction function" that can update the contents of one or more files, and "Upload function" that can upload the data contents of one or more desired sequencer among multiple sequencers to the desired standard file 2, a "download function" capable of downloading the contents of a desired standard file to a desired sequencer, and an "end function" capable of ending the processing operation of FIG.

Next, in step 201, when a desired function is selected from these functions and "display / correction function" is selected, the process moves to the flowchart of FIG. 3 and the upload function is selected. If the download function is selected, the process proceeds to the flowchart of FIG. 4, and if the download function is selected, the process proceeds to the flowchart of FIG. Then, when the end function is selected, the series of processing shown in FIG. 2 is ended.

Next, the "display / correction function" shown in FIG. 3 will be described. First, step 400 and step 301
And in step 302, the desired sequencer is determined. The desired sequencer can be determined by designating the address of the sequencer. That is,
In step 300, a station of the sequencer (which station the sequencer belongs to can be determined) is selected. Next, in step 301, a sequencer unit (a plurality of sequencers existing in the process can be determined by this unit) is selected. Next, in step 302, the address of the sequencer is determined by selecting the desired sequencer (the address of a specific sequencer can be determined from a plurality of sequencers belonging to the process), and the central processing computer 16 is determined. Causes the intermediate file storage device 13 to access the desired sequencer. By setting the addresses of a plurality of sequencers, it is possible to access a plurality of sequencers at the same time.

Next, in step 303, a desired one or more standard files are selected from the plurality of standard files. If the data of the sequencer selected here is uploaded to the standard file,
If it is not uploaded yet, the process proceeds to the next step and the process of FIG. 4 is performed prior to the process of step 304 to upload in advance. In addition, even if the contents of each standard file are modified, the contents before modification can be stored. Therefore, when the standard file is selected, not only the standard file type can be selected, but also files having the past contents can be selected from the standard files of the same type.

In step 304, the contents of the selected standard file are displayed for the selected sequencer.
This display is executed by the display device 18. Then, the content of the selected standard file is corrected by updating the screen of the display device while using the input device 20.

Then, the process proceeds to step 305. In this step, a save menu for saving the contents of the modified standard file is displayed. This save menu saves the modified standard file, downloads it to the selected sequencer, and ends the series of processing with the "download function" and saves the modified standard file and selects it. A "save function" that completes a series of processing without downloading to a sequencer
"Exit function" that terminates a series of processing without modifying or simply saving the displayed standard file, and without downloading it to the selected sequencer
Consists of Next, at step 306, a specific function is selected from these various functions, and the corresponding processing is executed. The download is executed by the process shown in FIG.

Next, the "upload function" will be described with reference to FIG. In step 400, by the same method as steps 300, 301 and 302 in FIG.
The sequencer address is determined. Here, when the address of the sequencer is determined, the model of the sequencer can be determined, and the relationship between the two is preset in a predetermined storage area of the central processing computer 16. Next, in step 401, the standard file of the other party to which the sequencer data is uploaded is selected. A specific converter that enables data exchange between the two is selected by determining the model of the sequencer and the type of the standard file. Then, the data is read from the selected sequencer, the data of the sequencer is converted by the selected converter, and then the converted data is uploaded to the selected standard file (step 402). There are as many converters as there are combinations of the number of models of sequencers and the number of standard files, and these converters are set in advance in a predetermined storage area of the central processing computer 16.

Next, the "download function" will be described with reference to FIG. In step 500, by the same method as steps 300, 301 and 302 in FIG.
The sequencer address is determined. Here, when the address of the sequencer is determined, the model of the sequencer can be determined, and the relationship between the two is set in a predetermined storage area of the central processing computer 16. Then, in step 501, the desired standard file is selected.
Next, in step 502, the data of the standard file selected by the specific converter is converted into the data of the sequencer of the selected model and downloaded to this sequencer. There are as many converters as there are combinations of the number of types of sequencers and the number of standard files, and these are set in advance in a predetermined storage area of the central processing computer 16. In this way, by downloading the data uploaded from the sequencer and accumulated in the standard file to the other sequencer from this standard file, it is possible to perform data conversion between different-type control devices.

According to the present embodiment, assuming that the number of sequencer models is 100, the number of converters is 100 × 5 = 500, considering that there are five standard files. It is an individual. Therefore, if this number of converters is prepared in advance, it becomes possible to exchange data between arbitrary sequencers via the standard file. On the other hand, in the case without the intermediate file structure as in the present invention, 4950 converters must be prepared. Usually, for example, in an FA factory that assembles automobiles, the number of sequencers tends to increase due to demands for higher functionality of automobiles, improvement in designability, or improvement in productivity, and all converters are required. It is extremely difficult to prepare.

In a network system having no intermediate file structure, every time a new model of sequencer is added, a converter must be provided between that sequencer and all existing sequencers.
In the network system of this embodiment, it is only necessary to add a converter between the newly added sequencer and standard file. Therefore, it is possible to easily cope with the version upgrade of the network integrated system.

The case where data exchange is required between sequencers is, for example, the case where it is desired to adjust the operation sequence, operation timing, etc. of actuators by loading data from one sequencer to another sequencer. . More specifically, taking an FA factory for automobile production as an example, a part of the equipment used in the door mounting process is diverted to a part of the tire mounting process, and a specific part for the tire mounting process is used. This is the case for fine adjustment.

Further, according to the present embodiment, various data individually set in each sequencer based on the model-specific specifications of each manufacturer can be organized into the contents of the five types of files. Therefore, the type of data can be easily specified, and the data exchange between the sequencers can be facilitated by saving the trouble of adapting the type of data converted between the sequencers of different manufacturers or different models. More specifically, taking an FA factory for automobile production as an example, when a new factory is established or the manufacturing line of the factory is changed to new equipment, the manufacturer or model of the sequencer used is changed. This is the case.

In this embodiment, step 2 in FIG.
A standard file creation function can be added to the initial menu shown in 00. When this "standard file creation function" is selected, the contents of the selected standard file can be newly created and downloaded to a desired sequencer, and new sequence control can be executed. With such a configuration, it is easy to upgrade the version of the network integrated system. Usually, for example,
In automobile production plants, it is necessary to upgrade the network integration system to enable production of new models. At this time, in a network system having no intermediate file structure as in the present invention, new data must be loaded for each individual sequencer, but in the network integrated system of the present invention, a newly created standard file or Since the contents of the updated standard file can be loaded into desired plural or all sequencers at a time, the version upgrade of the network integrated system can be performed easily in a short period of time.

Further, according to the present embodiment, since a network system connected to a plurality of sequencers can be constructed, the central processing computer can access a desired sequencer via the network. Therefore, even when a malfunction occurs in a certain sequencer and repair work is required, the remote operation of the sequencer can be performed without visiting the site. As a result, a safer automation line can be formed, which is extremely effective in eliminating personal injury. Since the sequencer can be remotely operated, it becomes possible to bypass the defective sequencer without going to the site and restore the repair completion line after repairing the sequencer.

Further, according to the above-mentioned embodiment, since the highest performance sequencer can be used for each process, the production efficiency in the FA factory can be greatly improved. The standard files are not limited to the above five types, and standard files capable of accumulating other types of data can be provided corresponding to the types of data set in the sequencer. As such, for example,
There are standard files that correspond to the information currently held by the sequencer itself, such as sequencer operation parameters and system memory. Further, in the present embodiment, the case where the control device is the sequencer has been described, but it goes without saying that the present invention can be applied to the construction of a network integrated system including other types of control devices.

Next, the operation when the apparatus of this embodiment functions as a program generator is changed by the flow chart (FIG. 6) and the screen of the display device (FIG. 7) which is changed as the routine shown in this flow chart progresses. Through 9). The processing routine of FIG. 6 is started by selecting the program generator function of the central processing computer 18, and in step 600,
The central processing computer 16 reads the contents of the program file 12C of the standard file and stores the program of each sequencer in a predetermined storage area. Here, it is assumed that the operation files of a plurality of sequencers are stored in advance in the program file.

Next, in step 602, each program is symbolized to create a database in which the programs and symbols are stored, for example, in the form of a table. Here, symbolization means associating a predetermined graphic with a program unit (the size of the program is not particularly limited) having a certain specific function. Therefore, the symbolized program unit can be visually recognized and can be grasped as one component such as one building block. This symbolization can be performed on the operation screen of the display device, which will be described with reference to FIG. 7 showing the operation screen.

The contents of the read program are displayed in the area 80 in the form of a ladder diagram. The displayed program is componentized as a specific symbol desired in the designated area of the area 81, and each componentized symbol has a desired name of 85 and / or a number of 84 (program function). Is preferably assigned to each program) so that a predetermined program is associated with a specific symbol so that the programs can be distinguished from each other.

"Part" with desired name and number
Are sequentially set in a predetermined storage area, and the position displayed as the menu is displayed at the position specified in the area 82. After that, by selecting a desired "part" displayed in the menu area of the area 82, a corresponding program is selected. The selected corresponding program is displayed in area 81 as a specific symbol 83 and its number as 84.

Further, the contents of the selected predetermined program are displayed in the area 80 in the form of a ladder diagram. The other area can be used as an operation area for giving an additional function.

Next, in step 602, "parts" are selected and arranged. The operation of this step is
As shown in FIG. 8, this is performed by sequentially arranging desired parts (symbols) adjacent to a symbol 90 corresponding to a predetermined process having a certain length represented by a rectangle. The component is selected from the component menu displayed in the area 80, and the component is displayed from the beginning of the process according to the order of selection. The arrangement of these parts is executed in the ladder diagram display area 91.

In the state shown in the figure, two dissimilar parts 96, 98 are arranged from the start side of the process, and the part 94 displayed at the first position in the equipment menu at the third position in the process. Indicates the state in which the array is about to be arranged. In the area 82, the enlarged symbol of the selected part, the part name, etc. are displayed.

Here, the array number 97 and the name 99 of the parts are displayed in the upper part of the arranged parts. The symbol corresponding to the program can be a graphic corresponding to the content of the program. For example, in the symbol 94, assuming that three rectangular small circles mean each of the robot arms, the program corresponding to the symbol recognizes that the three robot arms are used for control. .

Next, in step 603, the parts that are arranged are combined, that is, the programs that correspond to the parts are combined. In this step, the central processing computer stores the arrangement of the parts on the screen in a predetermined storage area in advance, fetches the contents of the program corresponding to the parts from a predetermined database, and arranges these programs in the arrangement order of the parts. Join. At this time, in the case of the program of the sequencer as in the present embodiment, the addresses may be commonly used among a plurality of programs, and when the programs are simply combined, signals that conflict with each other may be generated at the same address. It is often input in a short time, and the actuator cannot be normally operated using such a program in many cases. Therefore, on the operation screen corresponding to this step, a list of component names and used addresses is displayed in the order of arrangement of the components on the operation screen shown in FIG.

As a result, as shown in FIG. 9, the overlapping address can be immediately recognized visually.
Each range of used addresses corresponds to a fixed / shift selection area 110 as a means for selecting whether to fix or shift the address, and a range that is not a common address is selected by selecting the fixed side, Addresses are treated as fixed. On the other hand, the unique address is shifted to an unused address by selecting the shift side. For example, in the programs of the component array numbers 1 and 2 shown in the figure, the addresses X000 to X00F are used in duplicate, but the shift side is selected for the addresses in this range of the program of number 2 and The head address of the address range in which the unique address is to be shifted by the used address is input to the area 102.

The central processing computer 16 saves an address shift or fixed command, a shift range, and a shift destination as an instruction file in a predetermined storage area. Therefore, the central processing computer can immediately fix or shift the use address of each program based on this instruction file. And
After the addresses are fixed or shifted, the programs are combined in the set order to obtain a new program. As a result,
The used addresses of the input / output I / O cards of the obtained combined program are displayed in a list on the operation screen as shown in FIG. 10 (step 60).
4). In FIG. 10, a markup with a mark "○" next to the address indicates that it is a used address.

This used address is the I / O being used.
It is equal to the number of O-ports and is an important value for parts management.
A numerical value obtained by summing this numerical value for each individual card is displayed in the display area 101 as the number of points used.

As a breakdown for each card, the numerical value of the total count is displayed in the display areas 102 and 103 for the input card.
The output cards are displayed in the display areas 104 and 105, respectively, to support the parts arrangement work. The operation of the central processing computer described so far will be described more specifically based on the apparatus of FIG. Now, taking as an example a case of newly constructing a new process, a program of each sequencer for controlling a target operation in an existing process (for example, door installation or door welding in an automobile assembly line). Is read to the program file 12C in the standard file via the network.

Next, the central processing computer combines these programs based on the operation described in FIG. 6 and stores the combined program in the program file. Then, the saved new program can be operated based on the new program by downloading it from the program file to the sequencer existing in the newly provided process.

By doing so, a new program can be easily constructed only by combining existing programs without creating a new program from the beginning. This advantage is particularly remarkable in sequence control such as control of an industrial robot used in the production process. That is, a production process such as an assembly process is a series of individual processes, and the construction of a new process often depends on the order in which each of the individual processes is assembled. Therefore, it is extremely effective that a program adapted to a new process can be created only by freely combining programs corresponding to individual processes on the screen. In the above description, it is assumed that the central processing computer 16 has a standard file structure when a new program is created. However, the central processing computer can display a program unit on the display screen without the standard file structure. You can also create a new program by combining with.

[0058]

As described above, according to the present invention, since data can be exchanged between arbitrary control devices via the standard file, even if control devices of different models are used. It is possible to provide a network integrated control device capable of centrally controlling these control devices. Further, it is possible to provide a program generator control device capable of easily creating a new program by combining a plurality of programs.
