Sicherungssystems

Sicherungssystems is a term used to describe integrated systems designed to maintain safety, reliability, and security in complex technical environments. They are intended to prevent harm, minimize damage, and ensure continued operation by continuously monitoring conditions, evaluating risk, and initiating corrective actions when necessary. The exact composition varies by application, but typical components include sensors, controllers (such as safety PLCs), actuators, power supplies with fallback options, communications networks, and human–machine interfaces.

Design principles emphasize redundancy and diversity of channels, fail-safe or safe-state operation, and the segregation of safety functions from non-safety functions. Many Sicherungssystems implement multiple layers of protection, with safety integrity levels (SIL) or similar metrics guiding risk reduction. Verification, validation, and safety-case documentation are essential parts of the development and maintenance process.

Development and lifecycle follow hazard analysis, risk assessment, system architecture, hardware and software engineering, integration, testing, commissioning, operation, maintenance, and eventual decommissioning. Standards such as IEC 61508/61511, ISO 26262 for automotive, and railway standards influence design, assessment, and certification.

Applications range from industrial process control, building automation and security, medical devices, automotive safety systems, and transport infrastructure to data centers and critical IT services. In practice, Sicherungssystems bridge safety engineering and security engineering, integrating physical, logical, and organizational measures to reduce risk.
