RF685R Siemens

Область применения



The SIMATIC RF685R stationary UHF reader is ideally suited for applications along a production line or for reading points that can be implemented with two antennas at maximum.
The SIMATIC RF685R supports the established EPCglobal Class 1, Gen 2 standard and is offered in three versions: compliant with ETSI for Europe, compliant with FCC for USA/Canada, and compliant with CMIIT for China.

The high-performance SIMATIC RF685R reader has a built-in adaptive antenna and a connection for an external antenna. This enables single reading stations with one or two antennas or two logical reading stations to be implemented for reading on conveyor systems. The high radiated power of up to 2 W ERP / 4 W EIRP (dependent on antenna and cable) permits long ranges. The high degree of protection (IP65) of the overall system enables problem-free use, even under the most difficult environmental conditions.

One special feature of the RF685R is the integrated adaptive antenna. Thanks to their variable polarization, they can achieve high reading rates, even in areas with poor radio reception. In addition, project planning and spare parts inventory management are considerably simplified. For individual reading points along a production line, the RF685R is the ideal choice of device.

The integrated processing logic of the reader enables numerous functions of the higher-level software layers to be executed in the device itself. If necessary, the digital outputs for signaling functions are automatically controlled. The advantage of the SIMATIC RF685R is that its intelligence considerably reduces the cost for additional software modules (RFID middleware). Configuration, commissioning and diagnosis is performed via an easy-to-use Web interface that can be operated with a standard Internet browser. Access to the user interface data is also possible via the TIA Portal. The reader supports commissioning, such as the orientation of the antenna(s), or determining the radiant power required by means of corresponding software tools and the extended LED display.

A variety of diagnostic displays, such as the live radio signal diagram or the diagnostic logbook considerably simplifies and speeds up troubleshooting.

Data communication in the RF685R is executed either via an XML protocol with TCP/IP or via an S7 protocol via Profinet. Two Ethernet interfaces are available for data and diagnostics, of which one has Profinet capability.

The digital inputs and outputs (DI/DO) are used for simple process interfacing (sensors, actuators). The digital I/Os can be mapped directly into the IO image of a SIMATIC controller.

All antennas of the RF600 series are supported.

Note:
If the reader is used together with the ASM 456 communication module, be aware that only one reader can be connected to this communication module at a time. Two connected readers would exceed the maximum permissible power consumption.
