Abstract
A programmable logic controller has a wireless communication interface. A radio frequency identification chip set is mounted to, and is in communication with, the active elements of an integrated circuit on one or more circuit boards in the programmable controller. The chip set provides for radio frequency communication between the controller and other components either inside the controller or external to the controller. Identification information recorded on the chip may be interfaced over a network, particularly, an on-line network such as the Internet.
