Executive Summary In the domain of industrial automation, functional safety is paramount. For engineers utilizing Beckhoff’s TwinCAT automation suite, the SISTEMA Library serves as a critical bridge between hardware safety implementation and safety compliance validation. It provides a software interface that allows safety logic in TwinCAT to communicate directly with the SISTEMA calculation tool (Safety Integrity Software Tool), widely used for evaluating safety functions according to ISO 13849-1.

The programmer inserts the FB_SISTEMA_SafetyComponent blocks alongside the standard safety logic. For example, an emergency stop button is wired into a safety input terminal. The FB_SISTEMA_SafetyComponent block is instantiated to document that input terminal's safety parameters. Superior Drummer 3 Core Library Best - 3.79.94.248
Once the safety program is compiled, the user executes a command within the TwinCAT environment to "Export Safety Data." This generates the library file required by SISTEMA.
This write-up explores the functionality, architecture, and operational benefits of the Beckhoff SISTEMA Library within the context of machine safety design. To certify a machine under ISO 13849-1, engineers must calculate specific performance metrics for every safety function, most notably the Performance Level (PL) and the Probability of Dangerous Failure per Hour (PFH) .
