A system for designing visual information displayed on a monitor unit used in conjunction with a programmable controller

摘要

The monitor unit is coupled to a programmable controller (PLC) to monitor the work carried out by the I / O device controlled by PLC. The monitor unit comprises a display, a control unit and a memory. This system has an image creation tool, and generates a source image code of visual information reproduced on the display by the image creation tool. The image creation tool comprises a conversion means for converting the source image code into a corresponding bitmap image to transfer the bitmap image to the memory of the monitor unit in order to reproduce the visual information immediately to the display. For this reason, it is possible to eliminate the necessity of providing a high cost component for converting the source image code into a bitmap image on the monitor unit, and the visual information can be displayed on the display at high speed.
