Siemens releases UHF RFID readers

October 10, 2014 - Siemens releases Simatic RF685R, RF680R and RF650R UHF RFID readers. The three devices in different functional and performance classes enable users to implement RFID projects more quickly and to reduce plant downtimes. Thanks to their high IP65 degree of protection and integrated Profinet connection, the Simatic RF680R and RF685R devices are designed for use in the production environment, e.g. for the manufacture of multi-variant products. Users in the logistics sector can implement cost-efficient UHF projects using the Simatic RF650R.

Thanks to four interfaces for external antennas, the Simatic RF650R and RF680R can be used for applications such as RFID gates or multiple individual reading stations. For the first time, the RF685R reader has an adaptive antenna. This integrated, polarization variable antenna simplifies commissioning and engineering of RFID applications in the production environment. What is more, the automatic antenna adaptation improves reading and writing reliability. In addition, the RF685R also performs difficult identification tasks in highly reflective surroundings.

The high-quality wireless module and extensive evaluation algorithms boost the reliability of all new readers in the read and write processes. Functions such as the modification of performance or the dynamic "RSSI limit" adapt automatically to changing environmental conditions. This enables the readers to deliver precise results even when reading moving objects or when the transponders are subject to sensitivity tolerances. All devices in the new generation of readers can be integrated into IT networks by means of Ethernet, TCP/IP and the XML protocol.

For integration in automation systems, the RF680R and RF685R devices can be connected via the Profinet port to a controller, such as the Simatic S7. In this case the configuration and programming is carried out in the TIA Portal. Standard function blocks with a simple programming interface make integration into the user program easier, thereby reducing costs and potential sources of errors. This means the reader can be configured by means of Web-based Management which can be called, for example, directly from the TIA Portal. In addition to configuration and commissioning, users can also access extensive diagnostics options (for example: signal strength, recording frequency and transmit power) using an Internet browser.

Whether by remote connection or locally via the second RF680R/RF685R Ethernet port, diagnosis can take place during system operation without having to interrupt the higher-level system. This reduces not only the necessary effort and expense, but also the risk of incorrect readings and failures.
