Versatile UHF RFID reader

Thanks to the use of M12 industrial connectors and aluminium die-cast housings, the reader is said to be rugged enough to meet the most demanding requirements – as found in railway applications, for example – while the flexible software concept means that a few clicks are all it takes to switch the unit to a completely different application.

Typical applications might range from a simple PLC connection to the integration of signals with an ERP system or a connection to a train control system.

The UHF RFID reader is based on four basic versions: the LLRP 1.1, which is also designed to connect to the HARTING Ha-VIS middleware; a unit with OPC UA support that meets the Companion Specification for Auto ID Devices for uniform connection to ERP and PLC systems (interface description available at [email protected] or from the OPC Foundation); a Modbus TCP version for easy connection to PLC systems (which is also suitable for communication with older PLC systems); and a version containing embedded middleware for complete standards-based data pre-processing. Various communication facilities such as web services, database connections, UDP and TCP telegrams are available for configuration.
