How We Ensure Quality
Functional safety by design
For safety-critical systems we apply the IEC 61508 methodology and build custom safety-critical software and hardware designed up to SIL3.
Built for the field
We select long-lifecycle, industrial-temperature-grade components (typically −40 to +85 °C) and plan for obsolescence, because integrating a new device into a production chain can take years.
Deterministic timing where it matters
We design with explicit timing budgets: RTOS for the standard cases, FPGA-based solutions when microsecond determinism is non-negotiable.
Verification & validation
Structured design reviews, hardware and firmware testing, environmental/EMC testing, and a DFM approach before serial production.
Quality management system
ISO 9001-certified processes and standards compliance maintained through our EtherCAT Group, PI, OPC Foundation, and CLPA memberships.
Secure-by-design embedded systems
Secure boot, signed firmware updates, hardened communication stacks, and threat-model reviews — applied to the parts of your product that face the network.
Case Studies
Universal Nvidia-Based Robotics Platform
Challenge: Robot manufacturers had to build and maintain extra integration layers to connect standard modules and servo drives.
Solution: We developed a versatile robotics platform based on the NVIDIA Jetson Orin, supporting EtherCAT, PROFINET, and EtherNet/IP.
Result: Manufacturers connect standard modules and servo drives directly — without any additional integration layer.
Industrial Network Switch for Data Acquisition Systems
Challenge: Dewesoft needed a TSN-ready switch that wouldn't fail in harsh conditions and couldn't afford the field-reliability risk of their product.
Solution: We designed and prototyped an industrial network switch for DAQ systems based on ARM Cortex-A53 and Microsemi switching silicon.
Result: A TSN-ready hardware platform with high port density, custom power sourcing, and an enclosure engineered for reliable industrial operation.
EtherCAT Stepper Driver
Challenge: The client was locked into third-party drivers that lacked the fieldbus support and protection logic their next-gen platform needed.
Solution: We developed a custom solution supporting EtherCAT, CANopen, Modbus TCP/IP, and Modbus RTU, with 8 micro-step resolutions.
Result: Smooth motor movement with overvoltage and overcurrent protection, soft-start, and idle-current reduction.
OEM Servo Drive Platform
Challenge: The client depended on third-party servo-drive vendors and wanted to own its production and service model.
Solution: We developed a custom, OEM-branded servo drive concept for conveyor equipment, prepared for serial production.
Result: Lower BOM cost, full control over repair and service, supply-chain independence, and a clear path to serial production.
Firmware for Modbus RTU and HART Integration
Challenge: Euromisure WIKA Italia needed to modernise their interface module by adding support for two key industrial protocols.
Solution: FreeRTOS-based firmware with Modbus RTU and HART support, improved UART driver, and integrated code with full documentation.
Result: Extended product capability without disruption to existing customers, and a cleaner codebase the WIKA team can maintain in-house.

What is the difference between the IIoT and the standard approach in industrial automation systems and the power sector?
The standard approach solves specific tasks in controlling industrial processes. IIoT is an autonomous predictive system that usually is not directly part of the production process.
With IIoT, processes can be monitored by measuring the metrics needed for predictive maintenance, enabling faster decisions at the business level. It uses edge processing, where data is transmitted to the cloud, bypassing the transmission level to the PLC and SCADA system.
Why is real-time networking important for industrial automation, and what technologies and tools do we use to achieve this?
For most industrial automation systems, timing is crucial: they must be well-coordinated and react in real time to external events at critical moments to guarantee the safety and efficiency of the whole process. To ensure this, we use safe real-time operating systems and, for supercritical systems, industrial-standard FPGA solutions.
What is the lifecycle and temperature grade of components in industrial automation?
Solutions built for industrial automation have a long component lifecycle. Innovations must be considered from many angles, because selecting a new device or embedded system — and integrating it into the production chain — can take years, even decades. The temperature grade usually ranges from −40 to +85 °C, and our developers select components within these time and temperature constraints.
What is SIL? How is security defined at the hardware and software levels?
SIL stands for Safety Integrity Level and refers to the certification of software and hardware components to ensure their reliability and safety. SIL certification identifies all process hazards, assesses the risk of failure, and ensures that if a failure occurs, the component will "fail safely." For a given process there can be four levels, from SIL 1 to SIL 4, determined by the risk reduction factor (RRF). The level is ensured across software, hardware, and documented failure scenarios; each level has an acceptable failure rate — the higher the level, the lower the rate.
Why is industrial automation a conservative industry?
Plants are critical facilities. Reliability and resilience are essential for manufacturing systems because they directly affect people's lives — from industrial injuries to technological disasters. To prevent attacks on industrial facilities, systems must be minimally vulnerable at the device and protocol levels.
New technology takes time to industrialize and standards take a long time to adopt, so change comes slowly: for example, HMS Networks' research showed that, at the start of 2022, wireless protocols accounted for only 7%, with most data still transmitted over wired networks.
The hardware evolves, but popular networking technologies persist, and many industrial protocols are proprietary, so engineers must join the organization that develops a standard to learn how it works. That high entry threshold reflects the high reliability demands placed on these systems and it's what makes industrial automation so conservative.
