MANUFACTURING CONTROL NETWORK

A communications system includes a plurality of work stations and a relational database operatively linked therewith. Each of the workstations includes a computer terminal having a display and at least one input device, test apparatus operatively coupled to said computer terminal, and an assembly application program which generates a first display of an assembly procedure to be followed by an assembler on said display of said computer terminal and a second display screen for display of test results obtained by said test apparatus on said display of said computer terminal. The relational database stores data which is independent of the assembly program and which indicative of the assembly procedure used by the assembly application program. A data structure of the relational database includes an tracking table and an action table, in which the tracking table being used to link to data contained in the action table. The tracking table identifies a type of product, a serial number of the product, and process steps associated with the product, and the action table identifies work instructions, test files and automated manufacturing files.
