DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an intelligent operation panel which is connected to various control devices of at a factory, a plant, a construction vehicle, a monitoring system, or the like and functions as a man-machine interface. More particularly, the present invention concerns an intelligent operation panel which has a display device for displaying various states of a system by using numerical values, characters, figures, graphs, and the like and input means for designating input states with respect to a ten-key or a numeric keypad and various switches displayed on the display device, and which is capable of generating an operation panel of an arbitrary display screen by using image-drawing software.
In addition, the present invention relates to a method of controlling highlighted display for displaying an object graphic image by highlighting the same.
BACKGROUND ART
In recent years, in the technical field for effecting the control, monitoring, and the like of production lines, disaster-prevention and security systems, and manufacturing plants, in conjunction with the trends toward sophisticated functions and complexity of the systems subject to control, input/output operation panels for displaying inputs to and outputs from the systems have become large in size and complex with increasing numbers of operation switches and display units. For this reason, from the point of view of manufacturers, there have arisen problems including a decline in productivity and higher costs of the operation panels due to a large number of types of operation panels.
Accordingly, in recent years, graphic operation panels have been proposed in which a transparent touch panel is superposed on a dot display unit to form an operation panel, and display screen data for the operation panel to be displayed on the dot display unit can be generated freely by a user by using image-drawing software (e.g., Japanese Patent Application Laid-Open No. 190909/1990).
According to this type of graphic operation panel, an operating instruction can be imparted to the system by pressing a position on the touch panel corresponding to an operation switch rendered on the display unit, and various states of the system can be displayed on the display unit. The display screen data for the operation panel, which are generated by the user, are registered and stored in memory incorporated in the operation panel.
The graphic operation panel for which the generation of the screen has been completed is usually connected to external control devices, such as a sequencer, a host computer, and various control devices, within the system being used via various interfaces. In accordance with instructions from the external control devices and internal processing, the graphic operation panel visually displays through figures and graphs information concerning, for instance, the operating condition of the manufacturing plant, the position of an automated guided vehicle, display data from various sensors, notification of abnormalities, and the like, and functions to notify switch inputs and the like to the aforementioned external control devices.
According to conventional graphic operation panels of this type, an arrangement provided is such that graphic images, characters, and marks of a high frequency of use can be registered as files during the generation of the display screen, and, when necessary, the registered files can be invoked, as required, on the display screen during generation, so as to generate the display screen.
With this conventional art, however, those which can be registered as files are the fixed display element data necessary for displaying fixed display elements which do not change with a change with each state. Therefore, in the case of those, such as a numeric keypad, which, in order to allow their functions to be completely realized, require, besides the aforementioned fixed display element data (rendering data for rendering the numeric keypad), variable display element data for variably displaying a designated key, tou
