BACKGROUND OF THE INVENTION
The present invention relates to a tag name sharing apparatus, a tag name sharing method, and a tag name sharing method for sharing tag information for identifying a device to be controlled among a plurality of control programs for controlling devices arranged in a factory or the like The present invention relates to a computer-readable recording medium on which a program for causing a computer to execute the method is recorded.
[0002]
[Prior art]
In factories that produce things such as automobiles and electrical appliances, various machines have been introduced by factory automation. FIG. 10 is a block diagram illustrating an example of mechanical equipment arranged in a factory. As shown in FIG. 10, in the factory, there are a processing machine 1001 for changing the shape of a thing, a robot 1002 for assembling things, a conveyor 1003 for moving things, an automatic warehouse 1004 for keeping things, etc. The machine is arranged. These machines are generally controlled by a programmable controller (hereinafter referred to as a PC) 1005. In particular, the PC 1005 may be integratedly controlled with other machines by being connected via the network 1006.
[0003]
The machine control by the PC 1005 is defined by a control program such as a ladder program. FIG. 11 is a diagram illustrating an example of a ladder program. In FIG. 11, X0000 and Y0030 represent terminal numbers provided in the PC. In particular, the ladder program shown in FIG. 11 describes that Y0030 is turned on when X0000 is turned on.
[0004]
FIG. 12 is a diagram illustrating an example of a PC and a machine to be controlled. As shown in FIG. 12, the PC 1005 includes several terminals 1102 for connecting to devices such as a lamp, an alarm device, a sensor, and a switch. In particular, FIG. 12 shows a state in which the switch 1103 is connected to the terminal number X0000 and the lamp 1104 is connected to the terminal number Y0030. Therefore, when the ladder program shown in FIG. 11 is executed by the PC 1005, the lamp 1104 is turned on when the switch 1103 is turned on.
[0005]
A control program such as this ladder program is generally created by a control program creation application provided on a computer. A monitoring program for monitoring the state of the machine is also created by a monitoring program creation application provided on the computer. Furthermore, a monitoring program created by the monitoring program creation application (hereinafter referred to as a monitoring application), a simulation application that predicts the operation of the machine, and the like are also executed on the computer.
[0006]
FIG. 13 is an explanatory diagram for explaining an application example of the various applications described above. As shown in FIG. 13, a computer on which a control program creation application 1201, a monitoring application 1202, a simulation application 1203, and the like that are executed on a computer operate is connected to a network 1006 in a factory, so that a PC, a processing machine, and the like. The control program can be transmitted to the machine and the state of the machine can be confirmed.
[0007]
The monitoring application will be described below. FIG. 14 is an explanatory diagram for explaining an example of the monitoring application. In particular, the monitoring application performs a monitoring operation based on an allocation table created in advance. This monitoring operation is realized by displaying picture parts representing the state of each machine on the screen of the computer. In FIG. 14A, a lamp 301, a meter 302, and a graph 303 are shown as examples of the parts of the picture. Here, the parts of this picture are called objects.
[0008]
Therefore, it is necessary to assign an actual machine or a PC terminal to each object, and the assignment table represents the assignment. For example, FIG. 14B shows an example of the allocation table. For example, the lamp 301 is assigned as the object lamp 1 to the terminal Y0030. With this assignment table, the monitoring application can intuitively inform the operator of the state of the machine, for example, by changing the color of the picture of the lamp 301 when an ON state signal is input to the terminal Y0030. .
[0009]
Like this monitoring application, various applications use alphanumeric characters such as X0000 and Y0030 as the terminal names of PCs and machines, but this expression is difficult for the operator to understand and errors such as incorrect settings occur. Cause. Therefore, in general, names on the terminals that are easy for the operator to understand, such as “press start button” and “lighting lamp during operation” are given to facilitate the operation on the application. This name is called a tag name.
[0010]
FIG. 15 is an explanatory diagram for explaining a tag name. As shown in FIG. 15, the tag name is configured by a combination of a name of a device such as a connected sensor and an action name representing an operation. In particular, there are a plurality of action names such as “SEKURI” and “RETURN” for one device name. For example, in FIG. 15, the tag name “0.8 Metal Sekir 1 Sekir” puts the device specified by the name “0.8 Metal Sekir 1” into a state of action “Sekir”, or This indicates that the device with the name “0.8 Metal Seki 1” is in the “Sekir” state.
[0011]
Therefore, in order to use this tag name, it is necessary to create a terminal name assignment table in which the tag name is associated with the terminal name. In general, this terminal name assignment table is individually created and held by each of a plurality of applications operating in the same factory. However, if each application creates a tag name individually, the name that identifies it will differ even though the same device is specified as a control or monitoring target between applications. Produce. This causes confusion in developing and debugging multiple applications. A combination in which a tag name is associated with a terminal name is called a tag.
[0012]
Therefore, in general, when multiple different applications operate in the same factory, the tag names are unified among the applications. Therefore, when creating a program that implements the application or at the time of initial setting, the tag is already used by another application. When a name is created, a tag name sharing method is adopted in which the tag name is acquired and used.
[0013]
A conventional tag name sharing method will be described below. FIG. 16 is a software block diagram for explaining a conventional tag name sharing method. In FIG. 16, 101 is a display device such as a CRT, 102 is an input device such as a keyboard and mouse, 104 is a belt conveyor, a machine such as a contact switch, 103 and 106 are applications A and B for monitoring and controlling the machine, Reference numeral 105 denotes a tag name integrated application for tag name sharing among a plurality of applications. Here, it is assumed that the applications 103 and 106 are monitoring applications and have an initial setting function for setting project information, tag names, and the like, which will be described later.
[0014]
As shown in FIG. 16, the application 103 uses the project information defining unit 111, the tag name assigning unit 112, the project information managing unit 113, the tag managing unit 115, the terminal name assigning unit 116, and the tag name converting unit 117 as described above. Implement the setting function.
[0015]
Here, the project information definition unit 111 is a unit that arranges a picture part graphically representing the machine 104 to be monitored or controlled in one factory on an appropriate screen on the display device 101. The tag name assigning means 112 is a means for assigning a tag name named so as to be understood by a person to the machine information linked to the picture part defined by the project information defining means 111, and is a project information managing means. Reference numeral 113 denotes a means for managing the project information defined by the project information defining means 111 and the tag names assigned by the tag name assigning means 112.
[0016]
The tag management means 115 is means for managing tag names and terminal names as a terminal name assignment table, and the terminal name assignment means 116 is means for setting the actual machine position to the tag name. The conversion means 117 is a means for searching for the terminal name from the tag name. Furthermore, the application 103 includes a communication unit 118 that acquires machine information according to the above-described project information for an actual machine in order to perform a monitoring operation.
[0017]
The application 106 has the same configuration as that of the application 103, but only the tag management unit 115 is shown in FIG.
[0018]
On the other hand, the tag name integrated application 105 is identical to the terminal name assignment table reading means 121 that reads the terminal name assignment table managed by the tag management means 115 of the application, and the various tag names defined for each application. Of the same tag name search means 1801 for associating the terminal name and the terminal name assignment table stored in the tag management means 115 with the terminal name assigned by another application assigned to the tag name to which no terminal name is assigned Integration of tag names is realized by the allocation table writing means 126.
[0019]
Here, the applications 103 and 106 and the tag name integrated application 105 realize processing by the above means by a computer program. For example, each means is realized by a subroutine describing corresponding processing. Is done.
[0020]
Actually, the operator creates the project information using the input device 102 such as a keyboard and a mouse while viewing the display device 101 such as a CRT in the environment where the application as shown in FIG. 16 is executed. After the initial setting such as the above, the state shifts to the state monitoring operation of the machine 104 such as a PC or a processing machine.
[0021]
Next, tag name integration processing at the time of initial setting of the monitoring application will be described. FIG. 17 is a flowchart showing tag name integration processing in a conventional tag name sharing method. First, the operator executes the initial setting function of the application 103, creates project information from the input device 102 by the project information defining unit 111, and arranges the created project at an appropriate position on the display device 101 ( Step S201).
[0022]
FIG. 18 is an explanatory diagram for explaining the project information. As shown in FIG. 18A, the project information includes object information, a tag name assignment table, and a terminal name assignment table. Here, the object refers to a picture part used to represent the state of the machine as shown in FIG. In the object information, a name for identifying each object is defined. In FIG. 18B, 301 is defined as lamp 1, 302 is defined as meter 11, and 303 is defined as graph 21.
[0023]
Subsequently, the tag name assigning means 112 assigns tag names to these objects to create a tag name assignment table, and the created tag name assignment table is stored in a memory on the computer by the project information management means 113 ( Step S202). As shown in FIG. 18C, the tag name assignment table is a table in which names defined for each object and tag names correspond one-to-one. The operator only needs to name the tag name to be assigned unique within the same application, and does not need to know the tag name of another application.
[0024]
Next, the application 103 inquires of the tag name integrated application 105 as to whether or not a terminal name assignment table indicating the correspondence between tag names and terminal names has already been created in another application (step S203). Here, if a terminal name assignment table has already been created, the tag name integration application 105 assigns terminal names by tag name sharing processing (step S204) described later. If not created, the operator assigns terminal names on the application 103 (step S205). The terminal name assignment table is tabular electronic data in which each tag name and terminal name correspond one-to-one as shown in FIG.
[0025]
When the assignment of the terminal names is completed, the tag name conversion unit 117 searches for the tag names assigned to the objects from the terminal name assignment table for all the objects included in the project information (step S206). The associated terminal name is assigned to the lamp 1, for example, as Y0030 (step S207). When the assignment of terminal names to all objects is completed (Yes at step S208), the initial setting is completed, and the monitoring operation using the assigned terminal names is performed by the communication means 118, for example, the sensor is turned on or the belt conveyor Information of the machine 104 such as the operation speed is acquired (step S209).
[0026]
Next, a conventional tag name sharing process for sharing tag names among a plurality of applications in step S204 described above will be described. The tag name sharing process is performed by the tag name integration application 105. FIG. 19 is a flowchart showing a conventional tag name sharing process. In FIG. 19, first, the tag name integration application 105 reads the terminal name assignment table from the application 103 by the terminal name assignment table reading unit 121 (step S1901), and the existing tag name assignment table 1801 by the same tag name search unit 1801. Then, the same tag name as the tag name assigned in the read terminal name assignment table is searched (step S1902).
[0027]
Here, the existing terminal name assignment table is also read by the terminal name assignment table reading means 121, for example, from the tag management means 115 of another application 106. The same tag name can be searched using various methods used in general keyword searches, such as checking whether or not the names arranged in descending order are in order. Has been.
[0028]
When the search for the tag name is completed, the terminal name assigned to the searched tag name is written into the terminal name assignment table in the corresponding project information by the terminal name assignment table writing means 126 (step S1903).
[0029]
In this way, when a tag name has already been created and used by another application even between different applications, the terminal name assigned to that tag name is obtained and By adding to the terminal name assignment table, tag names can be integrated.
[0030]
As a prior art other than the tag name integration method described above, a method of using a single tag management means between a plurality of applications is also known. FIG. 20 is a software block diagram for explaining another conventional tag name integration method. In the method shown in FIG. 20, the application 107 is created in advance so as to share the same tag management means 119, and the process of diverting the terminal name assignment table is not necessary.
[0031]
[Problems to be solved by the invention]
However, in order to share tags in the conventional tag name integration method as described above, it is necessary to unify tag names between applications in advance. There was a problem that application development / operation efficiency was not able to be started, and it had fallen.
[0032]
In addition, tag names defined for each application must be associated one by one. In a large-scale system, for example, a factory with more than 3000 terminals, the operation in the application becomes complicated and an operation error occurs. There was a problem that was likely to occur.
[0033]
The present invention has been made in order to solve the above-described problems. A tag name sharing apparatus, a tag name sharing method, and a method for efficiently sharing a tag when a plurality of applications share a tag. An object of the present invention is to obtain a computer-readable recording medium in which a program to be executed is recorded.
[0034]
[Means for Solving the Problems]
In order to solve the above-described problems and achieve the object, the tag name sharing apparatus according to the present invention uses a name that can be intuitively understood by a person as a definition element that identifies the device and the state of the device. Between applications that assign a tag name, manage a terminal name assignment table in which the terminal name of the device is assigned to the assigned tag name, and perform control, monitoring, simulation operation, etc. of the device by displaying or specifying the tag name In the tag name sharing apparatus for sharing the tag name, the terminal name assignment table reading means for reading the terminal name assignment table managed by the application, the tag name integrated among a plurality of applications, and the The integrated terminal name assignment table to which the device terminals are assigned is managed by dividing the tag name into the device name and the action name, and the terminal name assignment table reading method. When the tag name in the terminal name assignment table read out by is divided into the device name and action name, and the divided device name is not included in the device name in the integrated terminal name assignment table, the device name is Integrated terminal name assignment that adds to the integrated terminal name assignment table when the action names that are added to the integrated terminal name assignment table and the divided action names are not included in the action names in the integrated terminal name assignment table A table management means, a tag name in the terminal name assignment table read by the terminal name assignment table reading means, and a tag name included in the integrated terminal name assignment table; Vs Attachment Ruta Group name association means; Matched by tag name matching means Terminal name assignment table writing means for writing the contents of the integrated terminal name assignment table into the terminal name assignment table managed by the application.
[0035]
According to this invention, the tag name defined in each application is read, and the read tag name If the divided device name is not included in the device name in the integrated terminal name assignment table, the device name is additionally registered in the integrated terminal name assignment table and divided. If the action name is not included in the action name in the integrated terminal name assignment table, the action name is additionally registered in the integrated terminal name assignment table, and the read tag name is already included in the integrated terminal name assignment table. Map the tag name Because it writes in the pin name assignment table of each application, In addition to being able to manage and integrate tag names in more detail for new tag names, It is possible to easily identify which tag name is newly registered in the integrated terminal name assignment table, and as a result, a common tag name is used between the applications. be able to.
[0038]
In the tag name sharing method according to the next invention, a tag name, which is a name that can be intuitively understood by a person, is assigned to a definition element that identifies a device and the state of the device, and the assigned tag name includes the above-described tag name. Tag name sharing that manages a terminal name assignment table that assigns terminal names of devices and shares the tag names between applications that control, monitor, or simulate operations of the devices by displaying or specifying the tag names In the method, a terminal name assignment table reading step for reading a terminal name assignment table managed by the application, and a tag name in the terminal name assignment table read by the terminal name assignment table reading step are used as a device name and an action name. And the divided device name is assigned a tag name integrated between a plurality of applications and the terminal of the device, and the tag name is the device name. When the device name is not included in the device name in the integrated terminal name assignment table managed by dividing it into the integrated terminal name assignment table, the device name is added to the integrated terminal name assignment table, and the divided action name is the integrated terminal name. When not included in the action name in the name assignment table, the terminal name read by the integrated terminal name assignment table management step for adding the action name to the integrated terminal name assignment table and the terminal name assignment table reading step The tag name in the allocation table and the tag name included in the integrated terminal name allocation table Vs Attachment Kick Tag name association step and association in the tag name association step Was And a terminal name assignment table writing step of writing the result into the terminal name assignment table managed by the application.

[0043]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a tag name sharing apparatus and a tag name sharing method according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.
[0044]
FIG. 1 is a software block diagram for explaining a tag name sharing method according to the present embodiment. In FIG. 1, parts that are the same as those in FIG. 16 are given the same reference numerals, and descriptions thereof are omitted here. In particular, in FIG. 1, the tag name integration application 120 is different from the tag name integration application 105 shown in FIG.
[0045]
The tag name integration application 120 includes a terminal name assignment table reading unit 121 that reads tag names defined by various applications, a tag name analysis unit 122 that divides the tag name into a device name and an action name, and a divided device Device name management means 123 that stores names as device name lists, action name management means 124 that stores divided action names as action name lists, and tag names of various applications using the device name list and action name list. It has integrated terminal name assignment table management means 125 for managing one integrated terminal name assignment table, and terminal name assignment table writing means 126 for writing tag names into the terminal name assignment tables of various applications.
[0046]
The tag name integration process at the time of initial setting of the monitoring application will be described below. Note that the flow of the tag name integration process is as shown in FIG. 17. In this embodiment, only the tag name sharing process (step S204 in FIG. 17) is different. In particular, tag name sharing processing will be described.
[0047]
FIG. 2 is a flowchart showing tag name sharing processing in the tag name sharing method according to the present embodiment. In the tag name sharing process according to the present embodiment, first, the tag name integration application 120 reads the terminal name assignment table stored in the tag management unit 115 of the application 103 by the terminal name assignment table reading unit 121, The tag name analysis unit 122 divides the tag name into a device name and an action name. FIG. 2 particularly shows this division process.
[0048]
In FIG. 2, the tag name integrated application 120 first confirms whether or not the tag name includes a character string registered in the action name list held by the action name management unit 124 (step S501). FIG. 3 is a diagram showing examples of the device name list and the action name list. In step S501 described above, the action name list as shown in FIG. This confirmation is performed by comparing character strings, but the method is not limited.
[0049]
If the tag name includes a character string registered in the action name list as shown in FIG. 3B, the remaining character string is added to the device name list held by the device name management unit 123. (Step S502). If it does not exist, it is confirmed whether or not the tag name includes a character string registered in the device name list as shown in FIG. 3A held by the device name management means 123 (step S503). If it is included, the remaining character string is added to the action name list held by the action name management means 124 (step S504).
[0050]
In FIG. 3A, A-M1 is a convenient number given to the device name and means device name 1 of application A. In FIG. 3B, A-O1 represents application A's name. Means action name 1. The device name list and the action name list are created as, for example, an electronic file in a tabular format.
[0051]
In step S503, if the tag name does not include the character string registered in the device name list, the operator divides the tag name into the device name and action name, and inputs the divided device name and action name. The device 102 is used to register the device name list and the action name list (steps S505 and S506). After that, tag integrated list creation processing for creating an integrated terminal name list is executed (step S507).
[0052]
FIG. 4 is a flowchart showing a tag integration list creation process. In FIG. 4, first, the operator associates a device name corresponding to an existing tag name with a device name corresponding to a new tag name (step S801). FIG. 5 is a diagram illustrating an example of contents already registered in the integrated terminal name assignment table. 5A is an example of an existing terminal name assignment table defined in application B. B-T1 is the first tag name of application B, and B-M1 is the first device of application B. B-O1-1 represents the first action of the first action name of application B. FIG. 5B is an example of a terminal name list and an action name list defined in the application B.
[0053]
FIG. 6 is a diagram illustrating an example of contents newly registered in the integrated terminal name assignment table as the application 103. The device name list and action name list corresponding to FIG. 6 are as shown in FIG. These tables have already been created by the operators of application B and application A, respectively. Therefore, in this example, the above-described step S801 associates the device name shown in FIG. 5A with the device name of the existing tag name and the device name shown in FIG. 6 as the device name of the new tag name. Do it.
[0054]
Specifically, the association by the operator is performed under a graphical user interface displayed on the display device 101. FIG. 7 is an explanatory diagram for explaining a specific procedure of association. For example, as shown in FIG. 7A, in order to associate the existing device name “B-M1” with the new device name “A-M1”, the information is displayed in the box 1501 as shown in FIG. 7C. The tag name “ST1-upper claw opening / closing” corresponding to “A-M1” in the new device name list and the tag name “B-M1” in the existing device name list displayed in the box 1502 are displayed. “Open / close upper nail 1” is selected by the input device 102 and the association button is pressed. Then, by repeating this procedure, a device name association result as shown in FIG. 7D is finally obtained.
[0055]
Next, the association between the existing action name list and the new action name list is performed in the same manner as the association of the device name list described above (step S802). For example, as shown in FIG. 7B, the existing action name “B-O1” is associated with the new action name “A-O1”. Thus, by associating the device name with the action name, an integrated tag list name is created, and the created integrated tag list name is stored as a terminal name assignment table by the integrated terminal name assignment table management means 125 ( Step S803). Finally, the terminal name assignment table writing unit 126 uses the integrated tag list name in the terminal name undetermined portion corresponding to the tag name in the terminal name assignment table stored in the tag management unit 115 of the application 103. Write the associated terminal name.
[0056]
FIG. 8 is a diagram illustrating an example of a tag integration list finally obtained. As shown in FIG. 8, the terminal names of control or monitoring target devices that are common between the application 103 and the application 106 can be specified even when the tag names are different.
[0057]
FIG. 9 is an explanatory diagram for explaining the association between a tag name and a device name / action name. In FIG. 9, the tag name “ST1 upper claw opening / closing” (A-T1) of the application 103 is composed of a device name A-M1 and an action name A-01-1, which is a device name B-M1 of the application B. And B-T1 ("upper claw 1 open / closed open") composed of the action name B-01-1, and eventually it can be known that the terminal name is X1A.
[0058]
As described above, according to the tag name sharing apparatus and tag name sharing method according to the embodiment, after creating a project in which a tag name is defined for each application in each application, Since tags with different tag names between multiple applications are linked and the linked results are given to each application, device information can be shared between multiple applications, application project creation work can be easily started, The efficiency can be increased.
[0059]
