When the mark of the landmark is displayed on the selected character card on the CRT screen, the mouse 6 is operated again, and the instrument displayed on the CRT screen (in FIG. 1, the instrument displayed on the right half of the screen). The instrument to be hung is selected from among the instruments. When the meter is selected, information on the position specified by the mouse is transmitted to the hanging display processing unit 11 via the keyboard 5 and the input processing unit 3, and
The bill display processing unit 11 stores the transmitted position information and the current CRT
After the selected meter is detected based on the coordinates of the image signal being transmitted, the setting address corresponding to the selected meter is read from the data memory 12.

Next, the tag display processing unit 11 searches the registered character card memory 9, searches for the character card with the mark, reads the identification code of the character card, and reads the identification code first. The data is transmitted to the communication processing unit 38 of the process control device via the communication processing unit 32 and the communication line 25 together with the setting destination address determined corresponding to the instrument. The communication processing unit 38 stores the transmitted identification code in a corresponding location of the identification code storage unit 40 according to the set destination address transmitted at the same time. Wallet display processing unit 11
Sends the identification code and the setting destination code to the communication line 25, and then outputs an image review signal requesting that the image currently displayed on the CRT be reviewed to the screen display processing unit 4. Upon receiving the image review signal from the hanging display processing unit, the screen display processing unit 4 stores the element of the instrument to be displayed from the identification code storage unit 40 of the process control device in the same manner as when the display of the general screen 34 is requested. For each figure, all stored identification codes are collected via the communication line 25, a character card corresponding to the collected identification code is read out from the registration / character card memory 9, and the elemental figure of the meter is read. Is superimposed and displayed. When the corresponding character card is read from the registered character card memory 9 in accordance with the identification code read out from the identification code storage unit 40 by the screen display processing unit 4, even if the mark is attached, the character card is removed except for the mark. Is read. That is, the mark of the landmark is not displayed on the attached character card. Note that the image review signal output by the tag display processing unit 11 is transmitted to all the process operation consoles connected to the communication line 25 via the communication processing unit 32 and the communication line 25.

If another instrument is designated by the mouse 6 after the hanging, the character card with the mark is attached to the newly designated instrument by the same procedure as described above. Next, when another character card without the mark in the menu display on the CRT is designated by the mouse, the mark of the mark in the registered character card memory 9 is not set at two or more places at the same time. , The previously set mark mark is deleted, and the mark mark is displayed on the newly designated character card in the same procedure as described above.

When the hanging is completed and the menu display of the character card becomes unnecessary, a signal for canceling the menu display is sent from the operator via the keyboard 5 to the screen display processing unit 4 via the input processing unit 3, and the screen display processing unit 4 Cancels the composition of the registered character card menu display. When the tag is no longer required and is to be removed, the corresponding character card position on the CRT screen is selected by the mouse 6 and when the tag release is designated, the position information and the release signal are input to the keyboard 5 and the input processing. It is sent to the bill display processing section 11 via the section 3. Wallet display processing unit 11
Detects the corresponding character card and the meter from the image signal output from the screen display processing unit 4 at that time and the information on the position, and outputs a signal for releasing the identification code of the corresponding character card and the process control device. The setting destination address of the corresponding instrument in the identification code storage unit 26 is transmitted to the communication processing unit 38 of the process control device 26 via the communication processing unit 32 and the communication line 25. After outputting the cancellation signal and the setting destination address, the hanging display processing section 11 outputs an image review signal to the screen display processing section 4. Also in this case, the image review signal is transmitted to all the other process operation consoles connected to the communication line 25 via the communication processing unit 32 and the communication line 25.

The communication processing unit 38 deletes the corresponding identification code stored in the transmitted setting destination address. When the screen display processing unit 4 searches the setting address of the identification code storage unit 40 corresponding to the instrument displayed on the CRT at that time according to the image review signal, the identification of the character card selected to cancel the tag is described. Since the code has been deleted, the character card for which the cancellation of the bill is specified by the mouse 6 is not displayed on the selected meter on the new screen.

The location of the element figure of each instrument at which the bill is to be placed may be the position designated by the mouse each time, or may be a position set in advance for each figure type.

Next, details of the processing of the screen display processing unit 4 will be described with reference to the flowchart shown in FIG. It is assumed that element figures representing a plurality of instruments are displayed on CRT1. First,
In step 14, a request input from the mouse 6 or the keyboard 5 is input to the input processing unit 3. In step 15, the request content is determined, and the process branches to a predetermined processing procedure. If the request content is a menu display of a character card, the process branches to step 16, where the screen display processing unit 4 reads the memory content of the registered character card memory 9 and places the read character card in the designated area of the screen being displayed. Merge menus and output screen data.
If the request content is a request for selecting a bill, the process branches to step 17, where the screen display processing unit 4 registers a character card including a character card with a mark based on a screen review signal output from the bill removal processing unit 10. Read the contents of the character card memory 9 and
Create screen data to replace the menu display part displayed on the CRT. If the request content is a bill display, the process branches to step 18 and, based on the image review signal output from the bill display processing unit 11, the identification code storage unit 40 of the process control device 26.
The identification code stored at the setting destination address determined for each of the instruments is read in association with the instrument. The character card corresponding to the read identification code is read from the registered character card memory 9, and screen data to be superimposed on the corresponding element graphic display position of the meter is created. Finally, in step 20, the screen data is converted into an image signal and output to CRT1.

FIG. 2 does not describe the cancellation of the menu display and the cancellation of the bill display, but as described above,
Processing is performed in a similar procedure.

Further, in the above-described embodiment, the character attached to the instrument is described as a character card. However, the present invention is not limited to the character card, and may be a graphic, a symbol, and the like.
