SIMATIC RTLS in practical use

Transparent electronics production in Fürth

With about 2,000 boxes of material in constant circulation, this is a production environment with a low volume but a high mix of final products. Using SIMATIC RTLS means increased throughput, with a minimum of search effort.

Flexible, adaptable locating solutions with SIMATIC RTLS

The system

One seamless, precise, and complete locating solution

Know what’s where and when: SIMATIC RTLS uses seamless locating to position all relevant assets –your workpieces, tools, even vehicles or robots – to within a few centimeters. Dynamically, in real time, and with precision. No matter where they are on the premises. It then makes that information available to higher-level systems. With such transparency, that all you need to do to optimize the movement of your assets, is analyze the location data.

Tap into the digital future

SIMATIC RTLS completes the digital twin of all your processes – from delivery to further processing and final assembly. How? All relevant objects in a plant or warehouse are fitted with a transponder for a start.

The transponder signals are bundled by gateways and picked up by a higher-level system. The calculated position is then provided to intelligent automation systems and manufacturing units.

Ultra-wideband technology (UWB) enables maximum precision and reliability: For local wireless communication, an extremely wide frequency range (3-7 GHz) with a bandwidth of at least 500 MHz is used to transmit weak wireless signals. This prevents the risk of interference with other systems.

The result is extremely precise object location with accuracy down to centimeters.

Location Intelligence

Real-time data as added value for even more transparency

Location Intelligence expands SIMATIC RTLS to include a digital twin of performance. This web-based software analyses and displays motion data, processes events, and can be activated directly from local ERP or MES systems. The result is a seamless solution linking software and hardware, IT and OT, and shop floor and top floor.

End-to-end overview of material flow and order information 

By connecting transponder ID and order data, Location Intelligence makes it possible to display order information paperlessly on SIMATIC RTLS ePaper transponders depending on the process stage and order status. Users can also follow individual workpieces or the entire order in real time using a digital card.


The transparency achieved in this way lets you individually optimize production and logistics processes. The key elements are what’s known as Geofences – virtually defined areas you can set using Drag & Drop. You can use these to monitor when a transponder enters or leaves a given area. These entry and exit events, and also throughput times, can be statistically evaluated, displayed, or linked with additional actions.


Using the Location Intelligence Event Handler based on Node-RED, a flow-based low-code programming tool, these events can trigger numerous actions, such as writing to an ERP system, controlling a PLC, sharing information with a shop floor management system, and much more besides.


You can also transfer KPIs, such as throughput for a given workflow or idle times, to the Cloud for further analysis while production is still in progress. That means you can make use of existing apps like Predictive Learning or Performance Insight on the Siemens Cloud platform MindSphere, with no need to invest in your own analytical tools. It’s also possible to compare workflows between locations in order to gain even deeper insights.


The combination of local and business information also ensures transparent workflows: Search processes are kept to a minimum and quality is improved since the positions of all relevant objects are displayed in real time on a range of terminals. Bottlenecks or deviations in the production plan are avoided thanks to the Geofences. At the same time, real-time analysis reveals undiscovered potentials for factory optimization, supporting rapid decision-making.

Expand your view of locating information

Data brings value. Tracking assets seamlessly offers unexpected and valuable insights into your production. Providing crucial information for higher-level systems. And laying the foundation for smooth, highly efficient, and safe workflows.

Module library for more efficient process control and automation

Easy integration of PLC systems and the SIMATIC RTLS locating system makes the next step possible for more efficient control and automation of processes using real-time data.

Using the new LRTLS library module, SIMATIC S7 controllers can receive location data direct from the Locating Manager. The data transfer uses the ExportAVT communication protocol based on TCP/IP. Additional function modules make it possible to implement basic Geofencing functions using the transponder coordinates received from the S7 – in other words, to monitor defined physical ranges. Another potential application: By connecting their local position with the RTLS plant coordinates, AGVs always know their precise location. Because the distance between two transponders can be precisely calculated in real time, it’s possible to maintain defined distances, which opens up totally new opportunities.

Benefits at a glance:

  • Use of real-time capability with no level in between
  • Easier to use for process control, regardless of additional business logic
  • Small sized use of defined physical ranges 

Quality according to plan

Get rid of the paper trail in your factory with a system that lets you locate every workpiece seamlessly. E-paper transponders display processing information in context of the current location – meaning your workers have access to information such as the order number or next process step directly on the E-ink display.

This is also more flexible and advantageous than traditional paper dispatch forms with processing statuses automatically recorded and continuous production documentation guaranteed. Enjoy this new dimension of quality management, based on a seamless digital infrastructure.

Employee safety has become an increasingly challenging topic: Intelligent approaches are in demand in the manufacturing industry and in logistics companies. This will become even more important, when capacities and productivity are ramped up again.

SIMATIC RTLS enables the measurement, monitoring and maintenance of the safety distance between individual employees. Using wearable transponders that interact with infrastructure devices, employee movements can also be monitored.

The new SieTrace application also helps ensure workforce distancing. It processes the location data of the transponders using an algorithm, recognizes distances between employees, and triggers an alarm signal to all groups of people involved if the distance is less than 1.5 meters.

SIMATIC RTLS – a smart decision:

  • Contact tracing via the RTLS monitoring software, which maintains a history of employee movements
  • RTLS infrastructure can be used for other tasks beside social distancing – e.g. production control and asset tracking
  • Tools such as the Production Digital Twin can utilize RTLS data to optimize processes and safety
