The present invention relates to an industrial control device and a control method that are controlled by a selected client terminal.

2. Description of the Related Art FIG. 6 is a block diagram showing a configuration of a conventional industrial control device of this kind.

As shown in FIG. 6, a conventional industrial control device 200a includes a sequencer 220 for sequentially controlling the operation of an equipment machine 240 installed in a factory,
Ethernet 250 with T250 and keyboard 251
0, a client terminal 210 accessing a database stored in the server 200, and a facility machine 240.
Of operating conditions and equipment 24 during sequence control
It is composed of an intelligent display unit 230 for displaying the operation condition and operation state that are input as 0, and are individually installed.

[0004] In the above, the server 200 and the client terminal 210 are connected by the Ethernet 50. Further, the client terminal 210 and the sequencer 220
Is connected by serial communication, and the sequencer 220
And the intelligent display 230 are connected by RS232C.

FIG. 7 is a diagram showing the internal configuration of each part of the conventional industrial control device shown in FIG.

In FIG. 7, a client terminal 210
Is equipped with an Ethernet communication unit 211 for establishing communication with the server 200 via the Ethernet 50 and a database access unit 212 for accessing a database.

[0007] The sequencer 220 includes a serial communication unit 221 for performing data communication with the client terminal 210 by serial communication, and a facility machine 240 via an I / O control unit 223.
Sequence control unit 222 for controlling the operation of RS232C
RS23 which communicates with intelligent terminal 230 via
2C communication unit 224 is provided.

The intelligent display 230 has a screen display / input unit 231.

[0009] Conventionally, when equipment machines installed in a factory are connected to each other to form a network, as shown in FIG. 6, when a database is stored in a server 200, a client terminal is connected to a database. Used a personal computer to make it easier to access. The facility machine 240 is generally controlled by the sequencer 220, and displays input operation conditions and sequence control of the facility machine 240 when operating the industrial control device 200. Note that the sequence control is to control the operation of the equipment machine or the like in accordance with a predetermined fixed sequence (operation procedure).

In this conventional example, the client terminal 210
A personal computer is used as a server, and the database on the server 200 is accessed by a Windows application (registered trademark of Microsoft Corporation) or a UNIX application (registered trademark of ATT Corporation). Windows applications and UNIX applications run on the client terminal 210
Stored on a hard disk (not shown). The sequencer 220 that controls the facility machine 240 is programmed in a special language dedicated to each sequencer.

In the intelligent display device 230 as well, the data setting input of the sequencer 220 and the display of the operation state are created by a screen creation tool in a special language which is not very familiar.

[0012]

In the conventional example shown in FIGS. 6 and 7, the client terminal 210, the sequencer 220 and the intelligent display 230 are individually installed as described above. Was connected by serial communication and RS232C. Therefore, there are problems that not only a plurality of devices are required for constructing the system, but also that the interface between the devices becomes complicated and high-speed processing cannot be performed.

When a personal computer is used as the client terminal, access to the database mounted on the server 200 is performed by a Windows application. In this case, it is possible to access the database without any problem.

However, when the server 200 is based on UNIX, there is a problem in the connectivity with the client terminal 210 from a functional point of view. It is known that an object-oriented language, for example, a Java (registered trademark of Sun Microsystems) language is appropriate for eliminating the occurrence of the connectivity problem. The Java execution environment can be implemented on a personal computer. However, since the programs running on Windows are large in size, a large-capacity hard disk for storing the programs is required, and a CPU having a very large heat generation is required as a CPU capable of high-speed processing. Here, since the hard disk has movable parts, it is easily affected by external operating environment conditions, and there has been a problem that stable operation in a place where operating environment conditions are poor such as a factory cannot be guaranteed. In addition, the surrounding environment temperature rises due to the large amount of heat generated by the CPU, which also limits the operating temperature conditions, which limits the installation location of the device and requires strict temperature control. There was a problem.

On the other hand, the sequencer 220 for controlling the equipment machine 240 is a highly reliable device having a large number of operation results, and programs have been developed for these devices in a special language that differs for each sequencer. Therefore, the sequencer 220 has a very high degree of hardware dependency, and there is no versatility of the control program developed with great care. For this reason, if the sequencer is changed to a sequencer of another manufacturer, there is no compatibility between the control programs, and the sequencer of another manufacturer cannot execute the control program. As a result, a control program must be developed each time, and not only a great deal of labor and cost is required, but also program resources are not inherited.

Similarly, in the intelligent display 230 connected to the sequencer 220, the input of the sequencer 220 and the display of the operation state can be easily created by a screen creation tool. However, this screen creation tool is also written in a special language that is not very common, and if it is changed to another manufacturer's intelligent display, there is no versatility of the program, so the other manufacturer's intelligent display is Program cannot be executed. Therefore, similarly to the sequencer, a control program must be developed each time, and not only a great deal of labor and cost are required, but also the program resources are not inherited.

Further, a keyboard and a CRT are required to display the setting input of data for accessing the database of the server 200 and the communication status. However, since the intelligent displays 220 cannot be shared between the sequencers 220, the number of the intelligent displays 220 is required by the number of the sequencers, and the apparatus becomes large and the installation space is increased. there were.

In view of the above, the emergence of an industrial control device equipped with the following functions has been desired.

The database stored in the server can be easily accessed.

Stable operation can be guaranteed in a place where operating environment conditions are bad, such as a factory.

The operation of the equipment machine and the robot can be controlled by a general-purpose program.

The data setting input and the display of the operation state of the industrial control device can be realized by a general-purpose program.

Data input and display of operation status can be performed for both the server, the facility machine, and the robot.

The multifunction and miniaturization of the industrial control device can save the installation space in the factory.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems and needs of the related art, and is intended for an industrial machine which controls the operations of equipment machines and robots by client terminals interconnected by a network.
