Edge Stack

Secure Machine Connectivity & Industrial Edge Computing

Secure Machine Connectivity & Edge Computing

SOTEC Edge Stack is a flexible software solution built to connect shop-floor machines to the cloud securely and efficiently. It collects, processes, and transmits data, executes edge computing applications, and provides the foundation for remote maintenance and centralized fleet management. Thanks to its containerized architecture, Edge Stack runs hardware-independently on existing infrastructure and scales modularly with your needs.

Broad support for industrial protocols – including OPC UA, Modbus, and Siemens S7 – ensures seamless integration into legacy and modern production environments. While configurable ingress components guarantee reliable data acquisition from diverse devices, egress components handle standardized forwarding to higher-level systems like SOTEC Scitis or leading public clouds. This flexible architecture allows the software to be tailored precisely to your operational requirements.

Key Benefits

Universal Machine Connectivity

Seamless integration of your existing machines through support for all common industrial protocols such as OPC UA, Modbus, or S7.

Integrated OT Security

Protect your production data and comply with future security standards (such as the Cyber Resilience Act) today through a consistent security-by-design principle.

Field-Tested Reliability

Rely on an industrial-grade solution proven in demanding 24/7 production environments across diverse customer deployments.

Hardware-Independent Architecture

Avoid vendor lock-in by deploying on any Docker-capable hardware and utilizing your existing infrastructure.

Modular Flexibility & Scale

Grows with your requirements – from connecting individual devices to managing entire machine fleets.

High Resource Efficiency

Minimize hardware footprint with a lightweight system design optimized for low-power devices and embedded systems.

Technical Features

Universal

Connectivity

Seamless protocol and cloud integration

  • Protocol Variety:Native connection of legacy machines via established standards like OPC UA, Modbus TCP, Siemens S7 or direct analog and digital I/Os.
  • Smart Bridges:Local data preprocessing on the shop floor and standardized transfer to the SOTEC Scitis platform or leading public clouds.
  • Secure Transport: Encrypted transmission of all machine data to protect against interception and manipulation.

Container Middleware

(Docker)

Modular app and software platform

  • Docker Foundation:Consistent use of microservices for clean software encapsulation and high system stability.
  • Open for Custom Apps:Seamless integration and containerized execution of custom applications and AI/ML algorithms.
  • Resource Efficiency:Lightweight system design optimized for minimal hardware requirements and embedded systems.

Lifecycle & Fleet

Management

Secure maintenance & automated updates

  • Central Edge Manager: Intuitive remote management, configuration, and monitoring of your entire device fleet through a single interface.
  • Signed OTA Updates: Secure over-the-air distribution of patches and features with robust dual-partition (A/B) rollback protection.
  • Secure Remote Access: Encrypted tunnel connection for rapid, reliable remote diagnostics and maintenance without onsite intervention.

Edge Stack securely collects and processes machine data at scale—helping you minimize downtime, manage your fleet centrally, and accelerate your digital manufacturing strategy.

Typical Use Cases

Machine Retrofit

Modernize legacy machines without costly capital expenditures. Edge Stack captures vendor-specific control signals directly at the machine level and converts them into standardized, cloud-ready data streams.

Energy & Consumption Monitoring

Collect real-time electricity, compressed air, and water consumption data directly from equipment and sensors via Modbus or OPC UA. Edge Stack continuously streams structured metrics to on-premises or cloud-based energy management software.

Predictive Maintenance

Extract key operational metrics like pressure, vibration, or cycle times straight from the PLC. Leveraging its open container runtime, Edge Stack allows you to deploy custom AI/ML models locally on the edge for real-time anomaly detection before failure occurs.

Cyber Resilience Act Ready

Edge Stack is built on modern security-by-design principles. With automated vulnerability management and tamper-proof, signed OTA updates, it guarantees the long-term integrity and security of your production environment.
