Next, referring to FIG.
Will be described. The monitor data memory 4 is roughly divided into a head address information header 30 for storing information relating to the configuration of the entire monitor data memory, such as a head address where each screen data of the entire monitor data memory 4 is stored, The memory stores canvas figure information for storing such a figure to be displayed, information about which device of the programmable controller 22 is to be monitored, information about characters to be displayed on each screen, and information about other auxiliary functions. The above-mentioned head address information header 3
0 is a head address header, and the head address information header 30 stores the total size of the stored monitor data memory 4, the canvas screen data information header 31, the monitor condition setting information header 33, and the text canvas setting information header 35. And an address indicating each of the auxiliary function information headers 37 are stored. The canvas figure information header 31 stores the total number of screens and the starting address of the canvas figure for each screen. After that, canvas figure data 3 for each screen
2 is stored. The canvas graphic data 32 mainly includes a portion indicating the type of graphic such as a straight line, a circle, and a square,
A portion indicating the type of line, such as a thin line, a thick line, and a broken line, a portion indicating a color, and coordinates indicating where on the screen the figure is to be arranged are displayed. Is configured. The monitor condition setting information header 33 includes the number of screens for which monitor conditions are set,
Also, the head address where the monitor condition setting information 34 for each screen is stored is stored. Thereafter, the monitor condition setting information 34 corresponding to each screen is stored.
The monitor condition setting information 34 for each screen includes a portion indicating the type of monitor such as a numerical value display, a character string display, and a component display;
And a monitor timing unit that indicates the timing of referring to the display position and the device of the programmer controller. By collecting a plurality of these, monitor condition data for one screen is configured. The text canvas setting information header 35 includes the number of screens for which the text canvas is set, and the text canvas setting information 3 for each screen.

By collecting a plurality of these, canvas text data for one screen is configured. The auxiliary function information header 37 stores the set auxiliary function start address. After that, conditions for operating the respective auxiliary functions are stored.

As described above, monitor data is created by operating the S / W package 24 for creating monitor data on the personal computer 23 or the like. The data to be set at this time includes a basic graphic portion to be displayed on the display device 8 and characters to be displayed therein, and, if necessary, device information inside the programmable controller or a device changed by key input. And so on. Thus, the monitor data is created.

The monitor data created as described above is
RO with a serial I / F such as RS232C from a personal computer
Transfer to M writer 25. After that, data is written to the monitor data memory 4 by the ROM writer 25. Normal,
The monitor data memory 4 is a memory such as a ROM. By writing data to the monitor data memory 4, monitor data is stored in the ROM. The ROM

Monitor data can also be written to the Further, the configuration and operation when the above-described monitor device is applied to a production line will be described. FIG. 13 shows a production line in a factory. In such a production line, a management personal computer or a larger computer 23a is usually installed at the beginning of the production line, and control information corresponding to a production plan and a product to be produced is transmitted to the production line (conveyor 28). To communicate. This management computer 23
The monitor data is stored in the storage device a. Usually, transmission of information related to manufacturing, for example, work instructions and assembly information is performed by a personal computer or a management computer such as a programmable controller. In other words, the management computer 23a always manages the position of the work 26 on which pallet 27 on which position on the conveyor 28 (tracking), and based on the information, gives production information such as work instructions to each station. To communicate. Therefore, if the product (work 26) is pulled out of the conveyor 28 without knowing the management computer, for example, when a site worker mistakenly pulls out the product (work 26), the production information of the subsequent product is obtained. Will be wrong. For example, it is assumed that products (workpieces 26) of the types A, B, C, D, and E are sequentially put into a production line and have different assembling contents. It is assumed that the product of C disappears where the management computer cannot be managed. Then, the production information such as work instructions is normally transmitted to the products A and B, but the product D flows on the line where the product C should originally come. But,
Since the management computer does not know that C has disappeared, it transmits the production information of C. That is, the information of C should be transmitted where the work information of D should be transmitted, and an incorrect product is produced.

[0011]

The conventional monitor device is configured as described above. When displaying a plurality of monitor data on the monitor device, the number of monitor data stored in the monitor data memory in the monitor device increases. Therefore, there is a problem that a large capacity monitor data memory is required, which increases the cost of the monitor device and increases the size of the monitor device. Further, when displaying a plurality of monitor data on the monitor device, it is necessary to temporarily store the monitor data in the monitor data memory in the monitor device, so that there is a problem that the monitor data processing time becomes longer. Further, as described above, the conventional flow working device uses the program in advance to move the work 26,
Further, since the passage timing of the station is set, the production information of the predetermined work 26 is set to be sent to the monitor device of the station with respect to the monitor device of each station in accordance with the preset passage timing. , A, B, C, D, E
When the C product (work 26) is lost in the continuous product, there is a problem that the screen display contents on the monitor device are displayed erroneously.

The present invention has been made to solve such a problem, and a first object of the present invention is to provide a monitor device capable of reducing a memory capacity in the monitor device.

A second object is to provide a monitor device capable of shortening a monitor data processing time in the monitor device. A third object is to always display accurate information on a monitor device used for a line.
