Steag Hamatech PLC DCS Servo Control System
The Steag Hamatech PLC/DCS/Servo Control system is a comprehensive automation platform engineered for advanced industrial control applications. Developed by the German manufacturer Steag Hamatech GmbH, this system integrates programmable logic control (PLC), distributed control system (DCS) capabilities, and high‑precision servo motion control into a unified architecture. It is specifically designed for complex production environments such as semiconductor manufacturing, solar panel production, and high‑end packaging machinery, where precise coordination of multiple axes and processes is critical.
At the core of the system is a modular controller that supports various I/O modules, communication interfaces, and servo drive connections. The platform is built on a robust real‑time operating system, ensuring deterministic response times even under heavy network loads. Its scalable design allows configurations ranging from stand‑alone machines to large, networked production lines with hundreds of axes and thousands of I/O points. The system is programmed using standard IEC 61131‑3 languages, including ladder logic, structured text, and sequential function charts, making it accessible to automation engineers worldwide.

Redundancy Ready: Supports CPU and communication redundancy for high‑availability applications (e.g., 24/7 production lines).
Web‑based Visualization: Integrated web server allows remote monitoring via standard browsers without additional software.
Typical Application Domains
Semiconductor manufacturing: Wafer handling, die bonding, and inspection systems.
Solar cell production: Coating, printing, and sorting machines with multiple indexing axes.
Pharmaceutical packaging: High‑speed filling, capping, and labeling lines.
Printing and converting: Web handling with tension control and register correction.
Installation and Commissioning Notes
System installation follows standard industrial control cabinet practices. The controller and I/O modules are mounted on DIN rails. Fieldbus cabling must adhere to the respective network specifications (e.g., shielded twisted‑pair for EtherCAT). Commissioning is performed using the engineering software, which provides a step‑by‑step wizard for hardware configuration, network parameterization, and axis tuning. The system includes an auto‑tuning function for servo drives, which calculates optimal gains based on the mechanical load. All configuration data can be stored in a central project file, simplifying system duplication and maintenance.
Compliance and Standards
The system complies with IEC 61131‑2, EN 61800‑3 (EMC for drives), and EN 62061 (functional safety). It carries CE marking and is RoHS compliant. The controller and modules are rated for pollution degree 2 environments.
Conclusion
The Steag Hamatech PLC/DCS/Servo Control system offers a powerful, unified platform for demanding automation tasks. Its seamless integration of logic, process control, and high‑precision motion makes it an excellent choice for machine builders and system integrators working on complex, multi‑disciplinary automation projects.
