2. Description of the Related Art In recent years,
In the technical field of production lines, disaster prevention / security systems, and plant control / monitoring, I / O operations that perform input to the system and display output from the system as the functions of the system to be controlled become more sophisticated and complicated. The number of operation switches and displays on the panel has also increased, making it larger.
This is becoming complicated, and therefore, from the viewpoint of the producer, there are problems such as a decrease in productivity and an increase in the cost of the operation panel due to the variety of operation panels.

Therefore, in recent years, a transparent touch panel is laminated on a dot display to form an operation panel, and the display screen data for the operation panel to be displayed on the dot display is used by a personal computer and predetermined drawing software. There has been proposed a graphic operation panel that can be freely created by the user (for example, Japanese Patent Laid-Open No. 2-190909).

According to this kind of graphic operation panel, it is possible to give an operation instruction to the system by pressing a position on the touch panel corresponding to the operation switch drawn on the display unit, and to display various states of the system. Can be displayed on the display. The display screen data for the operation panel created by the user is registered and stored in the memory built in the operation panel.

The graphic operation panel whose screen has been created is normally connected to an external control device such as a sequencer, a host computer and various control devices in the system used by various interfaces. Information related to, for example, the operating status of the plant, the position of the automated guided vehicle, the data display of various sensors, and anomaly notifications can be visually displayed in the form of graphics or graphs, etc., at the same time as the switch input by instructions from the external control device or internal processing Etc. to the external control device.

By the way, in this type of graphic operation panel, a rectangular shape is often adopted as the shape of the panel, but in the past, the rectangular panel is normally installed horizontally. Therefore, conventionally, even on the side of the screen creating apparatus that creates the screen data for the panel, the screen contents of the display unit and the program contents of the drawing software are set so as to be suitable for creating only standard horizontal screen data. Has been done.

Therefore, when screen data for vertical installation is created by using the conventional screen creating apparatus in order to install the panel in a place such as a column where vertical installation is more suitable,
A method of drawing by rotating figures and characters by 90 degrees is conceivable, but the display of the screen creation device does not support vertical placement, it is difficult to draw, and the previously created screen data for horizontal placement is used as an asset. There was a problem that I could not make use of it.

The present invention has been made in view of such circumstances, and when creating screen data for a graphic operation panel, it is possible to easily create screen data for a graphic operation panel so as to easily deal with any panel installation direction. The purpose is to provide a device.
