The library typically consists of several function blocks designed to handle different levels of the safety architecture:
Modern Beckhoff servo drives (like the AX5000 or AX8000 series) feature built-in safety options such as STO (Safe Torque Off) and SS1 (Safe Stop 1). The SISTEMA library includes the safety profiles for these option cards, treating the drive correctly as an "Output" subsystem element.

To certify a machine under ISO 13849-1, engineers must calculate specific performance metrics for every safety function, most notably the and the Probability of Dangerous Failure per Hour (PFH) . The library typically consists of several function blocks
When the bLogThisHour trigger is activated at the top of the hour, the program would execute a series of steps, each leveraging a different block from the library: When the bLogThisHour trigger is activated at the
Build the Safety Function: In your SISTEMA project, create a new Safety Function (SF). You can then pull Beckhoff components from the library into the "Subsystems" or "Elements" tabs.
