For "light industrial" applications, the reader SIMATIC RF650R represents a cost-effective solution for UHF projects. Thanks to the sophisticated radio module, hookups for four external antennas with a transmitting power of 30 dBm, and the "UHF for Industry" algorithms, a wide range of applications (e.g., RFID gates or multiple individual reading points) can be realized. The integration is carried out through Ethernet, TCP/IP and XML protocols.The devices RF680R and RF685R are designed for use in production environments thanks to their high IP65 degree of protection and integrated PROFINET port. With its integrated, adaptive antenna, the RF685R solves even challenging identification tasks in highly reflective surroundings with flying colors. The antenna polarization can be configured by the user via software command – as circular, linear-vertical or linear-horizontal. The advantage: The same device can be utilized for different applications. This not only simplifies the commissioning, but also the planning and spare parts management. The particular strength of this adaptive antenna, however, lies in the automatic control by the reader. Here, not the user has to make a determination, but instead the reader automatically selects the best antenna configuration for each individual reading operation based on special algorithms. This not only saves time during the commissioning, but also makes possible significantly better reading results.
The RF680R delivers twice as much transmitting power to its four antenna ports (33 dBm) as its smaller brother (RF650R). Both readers, the RF680R and RF685R, offer a second Ethernet port, through which, e.g., maintenance personnel on-site can directly connect to the device. Standard function blocks for controllers, such as the SIMATIC S7, simplify the integration.
Whether during commissioning or diagnostics, with the devices SIMATIC RF650R, RF680R and RF685R, software installations are a thing of the past. The user interface can easily be called up with an Internet browser. As a result, maintenance engineers – for example – can remotely connect to a device and carry out tasks from their office. The user interface via Web browser, the powerful commissioning and diagnostics functions as well as the sophisticated radio module with "UHF for Industry" evaluation algorithms are the same for all devices.=
Furthermore, all devices of the new reader generation, SIMATIC RF650R, RF680R and RF685R, can be integrated into IT environments through Ethernet, TCP/IP and XML protocols. The commands and events are exchanged in XML format. For the integration into automation systems, the devices RF680R and RF685R can be connected to a controller, e.g., SIMATIC S7, by means of the integrated PROFINET port. Standard function blocks with an easy programming interface facilitate the integration into the application program.
With the combination of high-quality radio module and extensive evaluation algorithms, first-class reading results are achieved. The algorithms, such as the automatic control of the transmitting power, not only lead to a high reading rate, but also to the least amount of energy emitted – to prevent interference at neighboring readers. At the same time, overshooting is reliably avoided with them. Many functions are designed to automatically adapt to changing environmental conditions (such as moving objects or tolerances in transponder sensitivity).
The new UHF RFID readers SIMATIC RF650R, RF680R and RF685R provide all capabilities to achieve high-quality reading results – without RFID experts having to optimize every reading point. RFID projects can be implemented more safely and quickly; the risk is lowered considerably. But there is more: The costs for operating the plant also drop. Since the cause of erroneous readings is apparent at a glance, problems are recognized and corrected faster. Project managers and plant operators thus have fewer things to worry about.
