Introduction

The TwinCAT RFID Reader Communication library makes communication with RFID readers possible from the PLC program.

RFID readers can be both pure readers and write/read devices. The term RFID reader is therefore used below without implying any restriction of functionality.

Even extensive applications that use different functions of the RFID reader can now be implemented easily. The implementation expenditure is very low, because no manufacturer-specific interface protocol needs to be investigated in detail and implemented. The frame structure, telegram composition, command designation, telegram detection and several other protocol peculiarities are implemented automatically by the library. The user can concentrate fully on his application and saves valuable development time.

The handling of the PLC library is the same for all supported RFID reader models. Even in the case of a change of manufacturer, only small changes need to be made to the application.

With the TwinCAT RFID library, the entire world of RFID technology can be used for the first time without expenditure.
