DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer.

In a distributed system that monitors and controls a factory line by communicating between computers via a network, an optimal model is selected for each computer, and therefore, in many cases, computers equipped with different CPUs are installed in the network. Mix.

For this reason, an application program for monitoring and control including a part of network communication is created for each of these models.

[0004]

2. Description of the Related Art FIG. 2 illustrates the configuration of a distributed system for monitoring and controlling a factory line.
A plurality of computers 10 (six computers A, B, C, D, E, and F) are connected by a network 12, and network communication between the computers 10 is performed by an application program 200 of each computer 10.

[0005]

[Problems to be solved by the invention]

The computer has a computer 1 with a different CPU.
Since 0s coexist, it is necessary to develop a program portion for performing network communication between the computers 10 in consideration of various definitions between the computers, which requires advanced technology, know-how, and experience.

For this reason, a tool is used that can develop a network communication program part very easily even between computers 10 with different CPUs, and the program part is efficiently created for each computer.

When the number of computers 10 increases and the path of network communication becomes complicated, a simple program error occurs in which communication conditions and communication partners are confused. In addition, since the network communication program portion is created for each computer, labor is required for managing them.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a computer for creating a communication program capable of reliably avoiding a simple program error and also making program management extremely easy. To provide.

[0010]

FIG. 1A shows the configuration of a distributed system (see FIG. 2). A plurality of computers 10 are connected via a network 12, and network communication is performed between the computers 10. It is.

In FIG. 1B, in the computer 10 according to the first invention, in any one of the computers 10 for creating a communication program, a definition means for defining each communication processing content between a communication source program and a communication destination program. 100, generating means 102 for generating a source code of a communication part between the communication source and the communication destination program based on the contents defined by the definition means 100, and a source code corresponding to the generated source code. Distribution means 1 for distributing to each computer 10 having the communication source and communication destination programs
04.

Further, in the computer 10 according to the second invention, in the computer 10 according to the first invention, a definition means 100 for defining each communication processing content between a program of a communication source and a program of a communication destination.
Is characterized in that a communication source and a communication destination defined in advance are selected by using a mouse.

[0013]

A computer 10 communicates with a user to define a communication condition, a communication partner, and the like, and distributes a source code generated from the definition contents to another computer 10 (the other computer 10 transmits the source code of the source code). It may be obtained by requesting transmission).

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a communication program creating method according to the present invention will be described below with reference to the drawings.

FIGS. 12, 13 and 14 illustrate the operation of the embodiment with reference to flowcharts. The user can set an application program 200 (see FIGS. 2 and 11) for performing network communication in a logical function group. (Object) and design (Step 120)
0).

Next, the computer 10 of the communication definition server (which defines the communication conditions, the communication partner, etc. in conversation with the user, and distributes the source code generated from the definition contents to other computers 10) is selected (for example, the computer 10). The computer B is selected as shown in FIG. 11), and the user logs in to the computer 10 (step 12).
02).

Further, the computer 10 of the communication definition server is provided with a source code generator (communication with the user, communication conditions,
A communication partner and the like are defined, and a program (contents of distributing a source code generated from the defined contents) to another computer 10 is installed (step 1204) and activated (step 1206).

When the source code generator is started, first, the main body of the application program 200 is programmed (step 1208: at this time, a tool specified at the time of installing the source code generator is used).

Then, the host name (computer name) and domain name (group name to which the object belongs) of the computer 10 existing in the network 12 are set on the screens of FIGS. 3 and 4 (steps 1210 and 1212), respectively. The host name and domain name where the object is arranged are set on the screen of FIG. 5 (steps 1214 and 1216).

The contents of each object are all set on the screens of FIGS. 6, 7 and 8 (steps 1300, 1300).
302), the screen of FIG. 9 or FIG. 10 (the screen of FIG. 9 is selected when the number is large, and the screen of FIG. 10 is selected when the number is small), and the communication source and the communication destination objects are designated. (Steps 1304, 1306, 1308).

When the object arrangement, the contents of the communication processing, the communication source and the communication destination are defined in this way, the computer 10 of the communication definition server generates the source code of the communication part with reference to the definition contents (step S10). 1308).

Further, the user sequentially logs in to all the computers 10 indicated by the definition contents and distributes the corresponding source codes as shown in FIG. 11 (steps 1400 and 140).
2, 1404, 1406, 1408, 1410, 141
2, 1414, 1416: In FIG. 11, computer B
Distributes the source code to the computer A, the computer D, and the computer F).

Finally, the source code is compiled and linked in the distribution destination computer 10 to generate an executable file of the application program 200 (steps 1418 and 1420), and all the application programs 200 are started (step 1418). 14
22).

As described above, according to the present embodiment, since the object arrangement, the contents of the communication processing, the communication source and the communication destination are defined by the conversation with the user using the visual screen, the simple arrangement relating to these is defined. It is possible to reliably avoid the occurrence of a program error.

Further, since all the source codes are generated only by the computer 10 of the communication definition server and these source codes are automatically distributed to the corresponding computer 10, the management of the program (200) becomes extremely easy. . In this embodiment, the source code is generated after all the communication definitions are completed. However, the source code may be generated every time the communication definition is partially performed.

[0026]

As described above, according to the present invention, one of the computers communicates with the user to define the communication conditions, the communication partner, and the like, and transmits the source code generated from the definition contents to another computer 10. Since the delivery, simple program mistakes can be avoided with certainty, and the management of the program becomes extremely easy.
