<p>PURPOSE:To obtain a compact control panel and to display freely the messages in terms of quantity and expression by extracting a message sentence corresponding to the input/output information out of a storage means and displaying it on a display means. CONSTITUTION:A starting file memory 4 stores the control information on the messages related to the information received from equipments. A video memory 5 stores the message information in response to the control information. A CPU 6 carries out a sequence program stored in a program memory 3. A CPU 7 transfers the arithmetic results of the CPU 6 to the equipments and the display information to a loader 2 respectively. A CPU 9 controls the transfer of the font information to a display device 11 from a video memory 10 based on the display information received from a programmable controller 1. Thus the messages are displayed on a CRT screen and various types of control panels are obtained in the compact sizes in response to the arithmetic results and the input/output information received from external equipments.</p> |
