Siemens Introduces Their New Generation of UHF Readers

By Admin

The new generation of UHF readers from Siemens comprises three devices with different functions and performance categories.


They offer a variety of options to reduce costs for project execution and downtimes. The integrated software, for example, features many commissioning
and diagnostics tools, and the Simatic RF685R reader is equipped with an adaptive antenna for particularly high coverage.

Reliable readers for production
The UHF reader Simatic RF680R with four connectors for external antennas and the Simatic RF685R with one integrated antenna and one external antenna connector are primarily designed for use in automated environments ‒ for example, in production lines. But they can also be used in applications in logistics processes that are closely related to production, so they have a high degree of protection (IP65) and are equipped with a wide array of diagnostics options. The integrated dual polarization antenna is the key feature of the RF685R. When plants are being designed, it is not always immediately clear whether antennas with linear or circular polarization will be needed, which is why the integrated antennas of the RF685R, which can switch from one mode to another, prove to be an advantage. The antenna can be adjusted automatically, increasing the reading and writing reliability. Furthermore, the RF685R also performs difficult identification tasks in highly reflecting environments. With the integrated Profinet port, the UHF reader can be easily integrated into Simatic S7 automation systems using the appropriate function blocks. The device is configured in TIA Portal. Diagnostics can be performed during operation, either via remote control or locally via a second Industrial Ethernet connection, without having to interrupt the higher-level system.

Powerful readers for logistics
The Simatic RF650R UHF reader is an economical alternative for logistics applications that do not require a special degree of protection or do not have high transmission power requirements.

Easy integration and diagnostics
All the devices in the new generation of readers can be integrated into IT environments using Ethernet, TCP/IP, and XML protocols. The integrated web server makes it possible to commission, configure, and troubleshoot all three types of devices – RF680R, RF685R, and RF650R – via web-based management. It is not necessary to install additional software on the PC or update existing configuration and diagnostics software.
