Multiprocessor communication system having a paritioned main memory where individual processors write to exclusive portions of the main memory and read from the entire main memory

摘要

A communication system which makes possible a very fast data exchange between connected stored program controls, which is important especially for the control of industrial processes. A total storage area is subdivided into partial storage areas, which are assigned to the stored program controls. Only in the start-up phase of a stored program control are complete data words transmitted, whereas during operation only data which has changed is transmitted.
