2 CIP Div. A DATA TERMINAL FOR A POINT-OF-MANUFACTURE DATA ACQUISITION SYSTEM Abstract of the Disclosure A data terminal for a point-of-manufacture data acquisition system for an industrial facility including a series of work stations through which workpiece units are transferred, the system comprising a multiplicity of identification members used to identify workpiece units, production operations, and operators. Each data terminal includes a simple, manually-operated data scanner; when punched card identification members are employed, the data scanner comprises one LED and one photo-transistor. The data terminal also includes a data store, a data display, and a microprocessor which controls entry and retrieval of data in the store and processes that data; each data terminal further includes program means for the microprocessor effectively controlling the sequence and acceptability of all data. The data terminal derives its power from DC power pulses transmitted to the terminal in synchronous shared time relation with data signals along transmission lines connecting all terminals to a central processor. A modification for use of optical or magnetic bar code identification members is also described. -1-
