Abstract

A tag for use in a press machine includes a reprogrammable storage area provided in the form of a read/write memory for storing reprogrammable die information associated with the die assembly. A communications device provided in the form of a transceiver transmits die data supplied by the read/write memory and receives data for storage in the read/write memory. The tag, which is integrally attached to one of the die members, establishes a wireless bi-directional communications link with a production monitoring system provided in the form of a reader module integrally associated with the press machine. The reader includes a transceiver arranged for RF communication with the tag transceiver. Die data received by the reader from the tag is supplied to a press controller, which may also provide the reader with information to transmit to the tag.
