2. Description of the Related Art In factories that produce things such as automobiles and electric appliances, factory automation is used.
Various machines have been introduced. FIG. 10 is a block diagram illustrating an example of mechanical equipment arranged in a factory. FIG.
As shown in FIG. 0, in a factory, a processing machine 1001 for changing the shape of an object and a robot 10 for assembling the object are provided.
02, machines such as a transporter 1003 for moving objects and an automatic warehouse 1004 for storing objects are arranged. These machines are generally controlled by a programmable controller (hereinafter, referred to as PC) 1005. In particular, this PC 1005
In some cases, the connection by the control unit 06 is controlled integrally with another machine.

The control of the machine by the PC 1005 is defined by a control program such as a ladder program.
FIG. 11 is a diagram illustrating an example of the ladder program. FIG.
In FIG. 1, X0000 and Y0030 each represent a terminal number provided in the PC. In particular, the ladder program shown in FIG.
Is turned on.

FIG. 12 is a diagram showing an example of a PC and a machine to be controlled. As shown in FIG.
Has several terminals 1102 for connecting to devices such as lamps, alarms, sensors, switches and the like.
In particular, in FIG. 12, the switch 1103 is connected to the terminal number X0000, and the lamp 110 is connected to the terminal number Y0030.
4 is connected. Therefore, this PC10
When the switch 1103 is turned on when the ladder program shown in FIG.
04 lights up.

A control program such as the ladder program is generally created by a control program creation application provided on a computer. Also, a monitoring program for monitoring the state of the machine is created by a monitoring program creation application provided on the computer. In addition, the monitoring program created by the monitoring program creation application
It is called a monitoring application. ) And a simulation application for predicting the operation of the machine are also executed on the computer.

FIG. 13 is an explanatory diagram for explaining an application example of the various applications described above. As shown in FIG. 13, a control program creation application 1201 executed on a computer, a monitoring application 1
The computer on which the simulation application 1203 and the like operate is connected to the network 1 in the factory.
By being connected to 006, a control program can be transmitted to a machine such as a PC or a processing machine, and the state of the machine can be confirmed.

Hereinafter, the monitoring application will be described. FIG. 14 is an explanatory diagram illustrating an example of a 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 a computer screen. In FIG. 14A, as an example of the parts of the picture,
A lamp 301, a meter 302, and a graph 303 are shown. Here, the parts of this picture are called objects.

Therefore, it is necessary to assign terminals of an actual machine or PC to each of the objects, and the assignment table shows the assignment. FIG. 14B shows an example of this assignment table. For example, the lamp 301 is a terminal Y as the object lamp 1.
0030 is allocated. According to this assignment table,
The monitoring application, for example, connects O to terminal Y0030.
When the signal in the N state is input, the state of the machine can be intuitively notified to the operator by changing the color of the picture of the lamp 301 or the like.

Various applications, such as this monitoring application, correspond to the above-mentioned X0000, Y0030
Although alphanumeric characters such as are used as terminal names of PCs and machines, this expression is difficult for an operator to understand and causes an error such as a setting error. Therefore, generally,
By giving the operator a name that is easy to understand, for example, "pressing the start button" and "lighting the lamp during operation", the operation on the application is facilitated. This name is called the tag name.

FIG. 15 is an explanatory diagram for explaining tag names. 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 "Segiri" and "Return" for one device name. For example, in FIG. 15, the tag name “0.8 Metal Segiri 1
"Segiri" means that the device specified by the name "0.8 Metal Segiri 1" is in the state of action "Segiri", or the device with the name "0.8 Metal Segiri 1" is ".

Therefore, in order to use the tag names, it is necessary to create a terminal name assignment table in which the tag names are associated with the terminal names. Generally, 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 used to identify the same device will be different even if the same device is specified as a control or monitoring target between applications. Is generated. This can cause confusion in developing and debugging multiple applications. Note that a combination in which a tag name is associated with a terminal name is called a tag.

Therefore, generally, in the same factory,
When multiple different applications operate, the tag names are unified among the applications.If a tag name is already created by another application at the time of creating a program that realizes the application or initial setting, A tag name sharing method of acquiring and diverting the tag name is adopted.

Hereinafter, a conventional tag name sharing method will be described. FIG. 16 is a software block diagram for explaining a conventional tag name sharing method. 16, 101 is a display device such as a CRT, 102 is an input device such as a keyboard and a mouse, 104 is a belt conveyor,
Machines such as a contact switch, 103 and 106 are applications A and B for monitoring and controlling the machine, and 105 are tag name integration applications for sharing tag names among a plurality of applications. Here, the applications 103 and 106 are:
It is assumed that the application is a monitoring application and has an initial setting function for setting project information, tag names, and the like, which will be described later.

As shown in FIG. 16, the application 103 includes a project information defining means 111, a tag name allocating means 112, a project information managing means 113, a tag managing means 115, a terminal name allocating means 116, and a tag name converting means 117. The above-mentioned initial setting function is realized.

Here, the project information defining means 111
Is a means for arranging, on a suitable screen on the display device 101, a picture component that graphically represents the machine 104 to be monitored or controlled in one factory. The tag name allocating means 112 is a means for allocating a tag name so that a person can be identified to the information of the machine linked to the picture component defined by the project information defining means 111. 113 is
This is a means for managing the project information defined by the project information definition means 111 and the tag names assigned by the tag name assignment means 112.

The tag management means 115 manages the tag name and the terminal name as a terminal name assignment table. The terminal name assignment means 116 sets the actual machine position in the tag name. The tag name conversion means 117 is means for searching for a terminal name from a tag name. Further, the application 103 includes a communication unit 118 that acquires machine information of an actual machine in accordance with the above-described project information in order to perform a monitoring operation.

Although the application 106 has the same configuration as the application 103, FIG. 16 shows only the tag management means 115 for the sake of simplicity.

On the other hand, the tag name integration application 10
Reference numeral 5 denotes a terminal name assignment table reading means 121 for reading a terminal name assignment table managed by the tag management means 115 of the application, and an identical tag name for linking the same from various tag names defined for each application A search unit 1801, a terminal name assignment table writing unit 126 for assigning a terminal name assigned by another application to a tag name to which no terminal name is assigned from a terminal name assignment table stored in the tag management unit 115; , Realizes integration of tag names.

Here, the applications 103 and 106 and the tag name integration application 105 realize the processing by each of the above means by a computer program.
This is realized by a subroutine describing the corresponding processing.

In practice, an operator operates a CRT in an environment where an application as shown in FIG.
Using the input device 102 such as a keyboard and a mouse while performing the initial setting such as the creation of the project information while viewing the display device 101 such as a PC, the operation shifts to the state monitoring operation of the machine 104 such as a PC or a processing machine. I do.

Next, the tag name integration processing at the time of initial setting of the monitoring application will be described. FIG. 17 is a flowchart showing a tag name integration process in the conventional tag name sharing method. First, the operator causes the initial setting function of the application 103 to be executed, and the input device 102
Then, the project information is created by the project information defining means 111, and the created project is arranged at an appropriate position on the display device 101 (step S201).

FIG. 18 is an explanatory diagram for explaining 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, reference numeral 301 denotes lamp 1,
302 is defined as the meter 11, and 303 is defined as the graph 21.

Subsequently, the tag name allocating means 112
Tag names are assigned to these objects to create a tag name assignment table, and the created tag name assignment table is stored in a memory or the like on a 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 so as to be unique within the same application, and does not need to know the tag names of other applications.

Next, the application 103 inquires of the tag name integration application 105 whether or not a terminal name assignment table indicating the correspondence between the tag name and the terminal name has already been created in another application (step S1). S203). Here, if the terminal name assignment table has already been created, the tag name integration application 1
05, a tag name sharing process (step S
Assignment of terminal names according to 204) is performed. If it has not been created, the operator can
3 is assigned a terminal name (step S3).
205). 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.

When the assignment of the terminal names is completed, next, for all the objects included in the project information,
The tag name assigned to the object is searched from the terminal name assignment table by the tag name conversion means 117 (step S2).
06), the associated terminal name is assigned to the lamp 1, for example, as Y0030 (step S207).
When the assignment of the terminal names to all the objects is completed (Yes at Step S208), the initial setting is completed, and the communication unit 118 performs a monitoring operation using the assigned terminal names, for example, a state in which the sensor is turned on or a state of the belt conveyor. The information of the machine 104 such as the operation speed of the machine 104 is obtained (step S209).

Next, a conventional tag name sharing process of sharing a tag name between a plurality of applications in the above-described step S204 will be described. The tag name sharing process is performed by the tag name integration application 105.
Does. 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 means 121 (step S1901), and the existing terminal name assignment table by the same tag name search means 1801. Next, a search is made for a tag name identical to the tag name assigned in the read terminal name assignment table (step S1902).

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.
In addition, the method of searching for the same tag name employs various methods used in general keyword search, such as a method of arranging names in descending order (a top order) and checking whether they match in order. Have been.

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). ).

As described above, even when a plurality of different applications have already created and used a tag name in another application, the terminal name assigned to the tag name is acquired, and its own terminal name is obtained. Tag names can be integrated by adding them to the terminal name assignment table in the application.

As a conventional technique other than the above-described tag name integration method, there is also known a method of using a single tag management means between a plurality of applications. 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 so that the process of diverting the terminal name assignment table becomes unnecessary.

[0031]

However, in order to share a tag in the conventional tag name integration method as described above, it is necessary to unify the tag name between applications in advance. Otherwise, there was a problem that the application project creation work could not be started and application development / operation efficiency was reduced.

Further, tag names defined for each application must be associated with each other. In a large-scale system, for example, in a factory having more than 3000 terminals, operation in the application becomes complicated. However, there is a problem that an operation error is likely to occur.
