Introduction: The Convergence of Automation and Safety Certification In the world of industrial automation, two forces are increasingly intertwined: high-performance machine control and strict functional safety compliance . For engineers using Beckhoff’s TwinCAT 3 software, bridging this gap traditionally meant manual calculations, external safety validation tools, and double-checking Parameter (P) values against complex standards like ISO 13849-1.
