## Abstract

Integration of Radio Frequency Identification (RFID) technology with an industrial controller to facilitate RFID tag printing and application of the RFID tags to manufactured items. RFID tags are printed based on RFID tag information that is generated and/or received by the industrial controller. A middleware software module can be included in the industrial controller to organize and schedule the RFID tag information in a manner compatible with an RFID tag printer. The RFID tag printer accesses the organized RFID tag information and tag printing occurs in conjunction with one or more industrial processes. The industrial controller can update a global registry with RFID tag information associated with printed RFID tags. The registry update procedure can be facilitated by creating email messages related to the RFID tags that have been created.
