A system for designing visual information on a monitor unit which enables the use of the monitor unit manufactured at a reduced cost but assures rapid reproduction of the intended visual information. The monitor unit is utilized in combination with a programmable logic controller (PLC) for monitoring a task to be performed by I/O devices managed by the PLC. The monitor unit includes a display, a controller section, and a memory. The system includes an image design tool operating on a personal computer for creating a source display code of the visual information to be reproduced on the display. The image design tool has a conversion means which translates the source display code into a corresponding bitmapped image and exports the bitmapped image to the monitor unit for immediate reproduction of the visual information on the display. Consequently, the monitor unit can be dispensed with a costly component of translating the source image code into the bitmapped image, yet effecting rapid reproduction of the visual information on the display directly from the bitmapped image transferred from the image design tool.

A moving object identification system with a novel coding scheme achieves 75% transmission efficiency. With this system, a transmittable range is expanded. Logical value assignment for residual resonant oscillations in a residual resonant signal is performed by comparing a residual frequency with a threshold frequency. A wave energy reduction of an ASK modulated signal is used to decrease the energy of the signal in order to distinguish similar residual frequencies in the case of extremely close communication. Reliability of Write/Read instructions in this system is improved by employing a test writing before an actual writing and a voltage monitoring device.
