[0014]
As shown in FIG. 3, the logic table 15 displays the operation of one application in a predetermined description format and describes the operation contents data in a sequential manner. The function table 16 and the object table 17 are referred to. It is possible.
[0015]
The function table 16 describes operations related to the display screen configuration that can be actually operated and viewed by the operator, and display content data in a predetermined description format, and what figure, character string, and reference at any position on the panel 11 Display the status data of the input / output device specified in the object table 17 and where to write the status data as input data input from the input means 10 (for example, data for production instructions, For example, the control device PLC is written as an input device).

Consists of screen configuration data related to the display screen configuration for displaying graphics, numerical values, and character strings, and function identification data for identifying which processing unit of the graphic panel system 4 the screen configuration data is processed by Has been.
[0016]
The object table 17 is a table that is referred to by the logic table 15 and the function table 16. In the logic table 15 and the function table 16, which input / output device (machine tool M / C 1, M / C 2... M / Cn abnormality or tool information) The operation for designating whether to read / write state data of the detection device, memory, file, etc.), and device designation data as display content data are set in a fixed format as shown in FIG.
[0017]
Next, the operation will be described. In a state where the transfer machine 1 is in operation, the communication sequence between the graphic panel system 4 and the control device PLC and between the production information recording system 5 and the control device PLC is adjusted by the general control system 3. And the status data of each machine tool M / C1, M / C2,... M / Cn respectively requested by the production information recording system 5 is exchanged via the communication system 2.
[0018]
One of the appropriate operation tables is read into the graphic panel system 4 and an application based on the operation table is realized, and the state data corresponding to the request of the application, that is, the graphic panel system 4 is read. The state data based on the description of the operation table is displayed on the panel 11 with a display screen configuration corresponding to the state data. As shown in FIG. 2, when the tool information is displayed on the panel 11, an operation table for displaying the tool information is read into the graphic panel system 4, and the display and operation set in the operation table are displayed. The content data is set in the corresponding variable of the program of the graphic panel system 4, and the logic processing unit 12 is executed according to the operation of the logic table 15 and the display content data.
[0019]
Each function processing unit 13 is executed by referring to the function table 16 of the logic table 15. Corresponding to each function identification data of the function table 16, each function processing unit 13 displays a figure or a character string at a predetermined position on the panel 11 according to the screen configuration data to constitute a display screen. For example, as shown in FIG. 2, the character string drawing function of the function table 16 is executed by the character string drawing function processing unit, and a character string “tool information” is displayed at a predetermined position on the panel 11. The numerical display function is executed and processed by the numerical display function processing unit, and the state data of the device designated by the device designation data in the referenced object table 17 is read from the state data storage means 8 and the state data (for example, FIG. 2, a value XXX indicating the number of rotations of the tool is displayed at a predetermined position on the display screen.
[0020]
Further, in a state where the screen is displayed on the panel 11 by referring to the function table 16, the logic processing unit 12 monitors the input from the input means 10 according to the logic table 15. The object table 17 is referred to, and the status data of the designated device is displayed. If there is an input to display the next page from the input means 10 in order to display the information of other tools in the state where the information of five types of tools is displayed on the panel 11 as the first page, the logic processing unit Reference numeral 12 refers to the object table 17 in accordance with the operation content data of the logic table 15, and displays the following five types of tool information different from the tool information on the first page as the second page on the panel 11.
[0021]
When other status data, for example, abnormality information is displayed on the panel 11 instead of the tool information display by input from the input means 10, the operation table for abnormality information is read instead of the operation table for tool information. The graphic panel system 4 realizes an application for displaying the abnormality information, and the abnormality information is displayed on the panel 11 in accordance with the display screen configuration described in the function table 16 in order to display the abnormality information. Further, the state data recorded in the recording unit 14 by the production information recording system 5 can be displayed by selecting the operation from the input unit 10.
[0022]
As described above, since the graphic panel system 4 is an application that executes each function based on the display and operation content data set in each operation table, when a new display or operation function is to be added, a predetermined format is used. The operation table describing the operation and display content data may be added according to the above. If the configuration of the machine tools M / C1, M / C2,... M / Cn is changed, the device designation data in the object table 17 is changed to device designation data for designating a new machine tool detection device. Only the state data to be displayed is changed with the operation and display functions as they are, and when the specification is changed for each transfer machine, the operation table display and display content data may be changed.
[0023]
Since it is only necessary to add and change the operation table in this way, there is no need to change the program itself, and changes, development and compilation from the source of the program are newly made to change specifications and add functions as before. After linking, the effort to verify the operation of the program is reduced, and all specifications can be handled quickly. In addition, since the operation table is a collection of data described in a predetermined description format corresponding to the variables of the graphic panel system 4, it is much easier to create than the case of describing the program source, and the operation table for each function. Even if the creators of the table are different, the description is unified, and even when a person different from the creator of the action table modifies and changes, the description contents of the action table can be easily understood and modified easily.
[0024]
Further, the production information recording system 5 implements an application that reads the data collection table and collects state data, and the realized application requests the state data from the general control system 3. In response to a request from the production information recording system 5, the integrated control system 3 allows communication between the production information recording system 5 and the control device PLC to collect state data of the production information recording system 5. Collection of the state data at this time is automatically performed based on the data collection table. For example, when the production information recording system 5 collects and records data indicating abnormality of the machine tools M / C1, M / C2,... M / Cn as state data, a data collection table for recording the abnormal data is produced. An application which is read into the information recording system 5 and records the abnormal data in the recording means 14 according to the description of the data collection table is realized, and the abnormal data is collected from the control device PLC. If the state data to be collected is data related to production information, a data collection table for recording the production information data is read and the production information data is recorded in the recording means 14 according to the description of the data collection table. Application is implemented, and status data relating to production information is collected from the control device PLC. The production information recording system 5 can be easily created and modified because the data collection table is described in a predetermined unified description format in substantially the same manner as the graphic panel system 4.
[0025]
【The invention's effect】
Above in the present invention is as, displayed on the graphic panel system reads the operation table that sets the operation content data, the graphics panel system based on the read operation table display is suitable can be realized and the operation function.
[0026]
In addition, since the operation table includes a logic table, a function table, and an object table for each data indicating a functional operation, a display screen configuration, and an input / output device, the data in each table can be easily edited.
[0027]
If the object table display and operation content data are changed, even if the configuration of the transfer machine is changed, the status data to be displayed is changed without changing the operation and display functions of the monitoring system, and the change in configuration can be easily handled. In addition, when adding new display and operation functions, it is only necessary to add an operation table and a data collection table. When responding to different specification requirements, the operation table and the data collection table can be edited according to the specifications. As a result, it is possible to respond quickly to all specifications and improve work efficiency, compared with the case of changing and developing from a conventional program source.
[0028]
In addition, the graphic panel system is a program that implements multiple functions by reading the content data into variables, including the variables set in the operation table , the display set in the operation table , and monitoring even if the transfer machine configuration is different Each system can be used in common, and development and specification changes can be made quickly and easily.
