• New computing platform makes the use of AI in industry transparent and secure

• Seamless integration with ctrlX OS and existing PLC systems

• Benefits for predictive maintenance and data-driven process optimization

Cambridge/Nuremberg, 18 November 2025 – Technology company Signaloid is expanding Bosch Rexroth’s ctrlX OS ecosystem with an innovative hardware solution that brings trustworthy artificial intelligence (AI) to industrial automation. The solution will be presented at the SPS trade fair in Nuremberg.

Signaloid’s technology enables real-time assessment of the reliability of AI and machine learning models — from predictive maintenance to production process optimization. The result: increased machine uptime, lower maintenance costs, and more efficient use of resources.

With its C0-microSD+ modules, Signaloid provides a compact, energy-efficient computing platform that fits directly into the microSD slot of Bosch Rexroth’s ctrlX CORE controllers. Thanks to its plug-and-play design, companies can execute AI models using real-time data from the ctrlX OS Data Layer — complete with quantitative uncertainty analysis of results.

“With Signaloid, we are bringing a technology into the ctrlX OS ecosystem that enables the safe and transparent use of AI in industrial environments,” says Hans Michael Krause, Director Partner Ecosystem at Bosch Rexroth. “Trustworthy AI and edge AI are key enablers for our customers — especially in applications where automation systems make autonomous decisions. We are excited that existing PLC systems can now be upgraded in this way through Signaloid’s technology.”

Unlocking the Full Potential of AI for Industry

Artificial intelligence and machine learning open up vast opportunities for industrial applications — from process optimization and predictive maintenance to more efficient resource utilization. These capabilities rely on data-driven predictions made by algorithms. However, these predictions are often based on uncertain or noisy data, for example due to sensor inaccuracies or loss of information during the digitization of real-world measurements. Such uncertainties can lead to incorrect decisions.

Signaloid solves this problem by making data uncertainties visible and quantifiable throughout computation. At the heart of the platform lies the C0 processor, a proprietary architecture capable of processing not only single values but entire probability distributions. This allows uncertainties to be quantified in real time, delivering dramatic performance gains compared to conventional processors. In benchmark tests, for example, the Signaloid platform achieved around 2,000 times faster uncertainty analysis for infrared camera data and roughly 95 times faster modeling of radiation absorption.

As a result, users can see how confident a prediction or decision truly is — providing the foundation for trustworthy AI in industrial applications.

“Imagine receiving not only a warning that a machine might soon fail, but also the exact probability of that happening. That’s what our technology delivers,” explains Prof. Phillip Stanley-Marbell, founder and CEO of Signaloid. “We enable companies to deploy machine learning and AI with confidence. Our partnership with Bosch Rexroth is an important step in making this technology available to the strong industrial base in the DACH region.”

Seamless Integration with ctrlX OS and Existing PLC Systems

Together with Bosch Rexroth’s ctrlX OS, the open Linux operating system for industrial controllers and edge devices, Signaloid’s platform integrates seamlessly into existing production environments. Plug-and-play modules in microSD or M.2 format allow existing PLC systems to be upgraded directly — without adding load to the main processor. This makes edge AI applications not only faster but also transparent and reliable. Alternatively, the Signaloid platform can also be deployed via cloud or hybrid solutions.

Key Benefits for Users

• Trustworthy AI/ML: Real-time assessment of model reliability for explainable and traceable AI decisions

• Predictive Maintenance: More accurate early fault detection and improved maintenance planning through probabilistic analysis

• Plug-and-Play Integration: Extend existing PLC systems without changes to control logic or infrastructure

• Edge Performance: Uncertainty analyses up to 2,000× faster than classical Monte Carlo simulations, with minimal energy consumption

• Compatibility: Full integration with ctrlX OS via standardized APIs, available for cloud, on-premise, and edge environments

SPS – Smart Production Solutions 2025 in Nuremberg

The Signaloid solution will be showcased at SPS – Smart Production Solutions 2025 in Nuremberg, November 25–27, 2025, in Hall 6, Booth 255.5. Together, Signaloid and Bosch Rexroth will demonstrate how AI-enabled control systems within the ctrlX OS ecosystem can operate securely, transparently, and resource-efficiently.
