CONTROLLER OPERATION SYSTEM

摘要

A controller operation system which enables flexible and smooth operation of various types of controllers using clients such as operation boards while restricting a memory capacity necessary for the clients. The image data on operation screens corresponding to the respective controllers (10 and 11) to which cache flags are added are stored in an image data storage unit (12d) of a server (12). When the operation board (13) operates the respective controllers (10 and 11), the image data on the controllers are obtained from the server (12) and displayed on a display unit (13b) while caching the image data in a cache memory (13e) in accordance with the cache flags.
