Can be.

[Action]

The central control circuit stores in advance the screen data of a plurality of screens transmitted from the host processor in the screen data memory. When a display request occurs, the screen number of the specified screen among the plurality of transmitted screens is input from the host processor, and the screen data of the specified screen is read out from the screen data memory based on the screen number and stored in the screen display memory. A display instruction is given to the giving screen control unit and displayed. Screen data to be transmitted in advance is frequently used only, and when displaying screen data not included in the screen data, the screen data is transmitted each time.

Also, the screen data of a plurality of screens transmitted from the higher-level processing device is composed of basic screen data forming a common part of the display screen, and when there is a screen portion to be added, the screen data of the screen portion added from the higher-level processing device is added. It is input from the host processor and given to the screen display memory, and the screen controller is given an instruction to display an additional screen. The screen controller reads the screen data of the screen to be added from the screen display memory based on the display instruction of the additional screen, and The information is given to the display unit and superimposed on the already displayed basic screen.

Therefore, the communication processing time can be shortened, the display response can be made faster, and the operability can be improved.
