An RFID reader and/or writer module in an industrial controller (e.g., PLC). The RFID module interfaces internally to the controller for tight integration therewith. The RFID module can also be part of a controller communications framework and as a standalone module with the PLC as a master device, and interact with the RFID module in the same manner as it interacts with other I/O devices connected to the controller. In another aspect, RFID read/write tag technology is incorporated into some or all major PLC and rack components, and utilized for wireless communication both between PLC system components and between the PLC and other devices, locations, and media. The RFID tag can be used to store and exchange electronic keying data, security information, module diagnostics and warranty information, series and revision levels code, I/O configuration data, and, replacement data. Artificial intelligence is also employed.
