RFID system - UHF range

RFID system - UHF range

With SIMATIC RF600, identification tasks are performed in the UHF range that demand a range of several meters. The system is suitable for storing and recording a unique identification according to the EPCglobal standard (Electronic Product Code) on products, containers or transport units. Storage of additional, freely-definable user data is also possible.

Various data carriers – from low-cost SmartLabels through to heat-resistant transponders that can be used for several thousand cycles – are available for industrial applications.

SIMATIC RF600 can be used with SIMATIC controllers, OPC UA clients, EtherNet/IP-based controllers and PC/IT systems. It can communicate data with cloud systems via an industrial IoT gateway.


SIMATIC RF600 has been specially developed for the requirements of industry. It enables economical and reliable use of RFID in production, materials management and logistics.

SIMATIC RF685R reader on a conveyor belt

SIMATIC RF600 is designed for the contact-free identification of every kind of object, such as transport containers, pallets, and production goods. It is also intended for general use such as recording goods in bulk. As a rule, these applications are open loops in which passive SmartLabels on goods, products, bulk containers or transport units are used. In this case, the system distinguishes itself due to its high reading speeds, large data transmission rates and the fact that it can handle long reading distances.

In addition, the system is suitable for reading and writing reusable transponders that are used in closed loops.

Typical applications include:

  • Acquisition of deliveries in incoming/outgoing goods departments.
  • Identification of transport containers, barrels or containers at important stations in the process; creation of a “Container passport” for automatic creation of a usage history.
  • Control of material flow and production in multi-variant, order-related production.
  • Labeling of products under severe ambient conditions, e.g. dust, dirt, high temperatures.
  • Stock monitoring and usage monitoring of tools and devices.
  • Automation of warehouses and distribution centers with industrial trucks.


SIMATIC RF600 readers are available both in versions with integrated antennas (RF610R, RF615R, RF685R) as well as with options for connecting external antennas (RF615R, RF650R, RF680R, RF685R).

For quick and easy cabling, pre-assembled cables are available in various lengths.

Multicolored LEDs indicate the status of reader and transponder.

The high degree of protection of the readers (up to IP67) enable them to be used in harsh industrial environments.

The SIMATIC RF600 series of transponders are used as mobile data carriers.

Transponders suitable for a wide variety of different requirements can be selected from an extensive range: The transponders are attached to the object to be identified, e.g. by means of screws, adhesive or pre-assembled spacer.

All of the SIMATIC RF600 readers are suitable for reliable reading and writing tasks in the UHF range and very long ranges up to 8 m.

The SIMATIC RF610R, RF615R, RF680R and RF685R readers are especially well-suited for use in production environments where a high protection class and integration into SIMATIC controllers are required. These readers also come with an extensive toolset for commissioning and diagnostics.

One special feature of the SIMATIC RF685R is the integrated adaptive antenna. Whether linear (horizontal/vertical), circular or automatic polarization, the integrated antenna of the RF685R achieves the best reading rates, even in difficult radio reception environments.

The compact SIMATIC RF610R and RF615R readers are offered for use in confined spaces, such as in conveyor systems. These new readers each have an internal, circular polarized antenna and ranges of up to 1 m. An external antenna can also be connected to the SIMATIC RF615R compact reader, which increases the range up to 4 m.

User-friendly function blocks simplify programming in Step 7 or the TIA Portal. Special functions are available in areas hostile to wireless communication encountered in production environments, such as reflections and dead zones resulting from metal or superimposed radio fields due to a high reader density.

In this manner, process stability is substantially increased by automatic adaptation of the transmit power and intelligent filtering of the reading results. The multi-stage filter concept ensures that, based on the wireless properties, the correct transponder within the RF field of the reader is always processed. The appropriate data storage medium is automatically selected on the basis of various indicators, such as the evaluation of the RSSI value (Received Signal Strength Indicator), the reading frequency, or the transmit power required.

Transponders that have already been processed can be stored in a “blacklist” in the reader and thus filtered out. Various mechanisms can be activated according to requirements.

All SIMATIC RF600 readers can be set up and diagnosed using a web browser. For the SIMATIC RF610R, RF615R, RF680R and RF685R readers, commissioning and diagnostics in the TIA Portal is also possible.

The SIMATIC RF650R reader is used mainly in logistics applications where a high protection class and SIMATIC integration are of lesser importance. With its four external antenna connections, as many as four individual reading stations or large gate applications can be implemented. The integrated processing logic allows comprehensive filter functions and control of the digital inputs/outputs in the reader itself. Configuration, commissioning and diagnostics are easily possible by means of a web browser, without the need for installing additional software.

The SIMATIC RF600 readers support OPC UA as an interface to the IIoT world and communicate using the data model of the OPC UA AutoID Companion Specification V1.0. Especially in the context of the Siemens solution portfolio for Industrie 4.0 and digitalization, this interface plays a key role in networking sensors, automation systems and IT systems. As standard, the OPC UA interface enables vendor-independent communication within automation systems and a standardized connection of the SIMATIC RF600 readers to cloud applications such as the open, cloud-based MindSphere IoT operating system via an industrial IoT gateway such as RUGGEDCOM RX1400 with CloudConnect or MindConnect Nano. This opens up exciting new possibilities for using current production data and enables worldwide availability of KPIs.

External sensor technology (e.g. light barriers or motion detectors) and indicator lamps or acoustic signaling elements are integrated by means of the digital inputs and outputs.


A wide range of communication modules, function blocks, as well as high-performance drivers and function libraries enable easy and quick integration into user applications.

The SIMATIC RF610R, RF615R, RF650R, RF680R and RF685R devices can be integrated in PC/IT environments using a simple XML protocol or via OPC UA. Programming examples are available for this purpose.

Because the SIMATIC RF610R, RF615R, RF680R and RF685R readers are part of Totally Integrated Automation (TIA), connection to automation systems such as SIMATIC S7 is easy via plug-and-play. The device information and easy-to-operate identification profile function blocks are included as standard features in TIA Portal V14 and higher (RF650R, RF680R, RF685) or V15.1 and higher (RF610R, RF615R).
