Manufacturing management equipment, manufacturing management system, manufacturing management methods and manufacturing management procedures

Abstract

A manufacturing management device monitors manufacturing data related to a manufacturing process and responds with status information including manufacturing data and timing information of when the manufacturing data changes. The manufacturing management device includes at least one memory and at least one processor. Whenever the manufacturing data changes, the processor generates status information at the time of the change and sequentially overwrites and stores the generated status information in the memory. Simultaneously, it receives requests associated with timing information included in the response and responds only with the status information stored in the memory if the timing information associated with the request differs from the timing information stored in the memory.
