RTLS system for real-time locating

With SIMATIC RTLS, you always know where everything is located in industrial applications. Thanks to seamless real-time positioning, the scalable RTLS makes it possible to precisely locate relevant assets in production and logistics. Precision for automation. Driven by data.

Fixed reference points

The permanently installed gateways receive real-time positioning data from the transponders, furnish it with a timestamp, and transmit it to the server.

Workplace safety

During challenging times in particular, RTLS is especially important for determining and monitoring distances between employees. If the distance falls below a defined minimum, the relevant employees immediately receive a warning signal.

Automated guided vehicles

Automated guided vehicles (AGVs) have become an essential component of many industrial processes. RTLS is able to track their movements and ensures that an AGV “sees” potential obstacles and avoids them.

Installation on moving objects

Transponders are fitted to workpieces, robots, vehicles, etc. and transmit signals at defined intervals. They can visualize information on an e-ink display and are available in different designs, including OEM versions.

Maximum transparency through indoor and outdoor locating

Real-time locating of relevant assets ensures maximum transparency and opens up brand-new prospects in a wide range of applications. With the knowledge of what is moving where and when and the ability to visualize these data points, you’re able to remove bottlenecks and boost throughput and efficiency.

Significantly reduce your search times

SIMATIC RTLS lets you locate relevant assets in real time with an accuracy measured in centimeters – whether workpieces, tools, automated guided vehicles (AGVs), robots, or even employees. As a result, you can eliminate time-consuming search processes and optimize your material inventory.

Complete positioning solution – and trailblazer for the digital transformation

SIMATIC RTLS (real-time locating system) is a critical component of industry on the way to implementing your customized digitalization strategy and enables you to advance the digital transformation of your company.

Tap into the digital future

SIMATIC RTLS completes the digital twin of your processes – from delivery to further processing to final assembly. For this purpose, all relevant objects in the plant or warehouse are first equipped with a transponder. Gateways bundle the transponder signals and make them available to the higher-level system Locating Manager. Here, the positions of the objects are calculated and forwarded to intelligent automation systems and production units.


RTLS uses highly precise and reliable ultra-wideband (UWB) technology, which utilizes an extremely wide frequency range (3-7 GHz) with a bandwidth of at least 500 MHz for short-range radio communication.

Greater transparency in production and logistics – without paper

SIMATIC RTLS4083T, Plus provides precise locating data for relevant assets and people in real time on its 3" display. Thus, the compact ePaper transponder with rechargeable battery in high protection class plays a key role for more efficient processes.

  • Better process management and paperless production
  • Real-time process monitoring
  • Implementation of safety concepts in challenging times

Real-time positioning data for maximum transparency based on optimization

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.

Comprehensive overview of material flows and order information

Using Location Intelligence, you can link transponder IDs to order data in order to display order information on SIMATIC RTLS ePaper transponders – while remaining completely paperless. The resulting increase in transparency makes it possible to optimize processes individually. The key is “geofences” – virtually defined areas that can be created using drag and drop and allow you to monitor when a transponder enters or leaves an area. These entrance and exit events as well as throughput times can be statistically evaluated, visualized, or linked to additional actions. Consequently, bottlenecks and deviations from the production schedule are detected and optimization measures are implemented quickly and strategically.

The Location Intelligence Event Handler enables a highly flexible and targeted assignment of actions to these events – such as controlling a PLC or sharing information with an ERP, MES, or shop-floor management system. It also makes it possible to transfer KPIs, including dwell and throughout times, to the cloud for advanced analytics while production is still in progress. This allows you to use apps that are already available on Siemens’ MindSphere cloud platform, like Predictive Learning and Performance Insight, without having to invest in your own analysis tools. You can also compare workflows across locations.

The tremendous potential of real-time positioning data

Data creates value. This is especially clear when it comes to locating relevant assets in production and logistics.

Function block library for more efficient process control and automation

The integration of your PLC systems in SIMATIC RTLS enables much more efficient process control and process automation. All you need is the new LRTLS function block library, which allows SIMATIC S7 controllers to receive locating data directly from the Locating Manager. Other function blocks make it possible to implement geofencing functions – in other words, to monitor defined physical areas – using the transponder coordinates received from the S7. In addition, AGVs always “know” their exact location by linking their local position to RTLS factory coordinates.
