Sistema Library — Beckhoff
: Open SISTEMA and use the "Library" menu to import the downloaded Beckhoff .slb file.
The MTTFd_Channel_A input expects years (per ISO 13849-1 standard). For electronic components with very high MTTFd (e.g., 10,000 years), the library caps the value at the maximum level (2500 years + high value = "high").
The is a digital data collection provided by Beckhoff to support machine safety evaluations using the SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications) utility . Purpose and Functionality
Safe outputs include digital output terminals (e.g., EL2904) and integrated drive safety functions like the AX5000 or AX8000 servo drives featuring Safe Torque Off (STO). The library provides the exact probability of a dangerous failure per hour (PFHd) for these complex electronic subsystems. Step-by-Step Integration Workflow

The library is not a replacement for TwinSAFE logic (which runs on EL6900 terminals). Instead, it is a . You can pass parameters from TwinSAFE safety inputs (via ADS communication) into the Tc3_Sistema function block running on the standard PLC core.
To understand the magic of the Beckhoff implementation, we first have to look at the source. (Safety Integrity Software Tool for Evaluation and Machine Application) is a software tool developed by the IFA (Institute for Occupational Safety and Health) in Germany. It is the global gold standard for calculating the safety performance of machinery. It answers the critical question: “Is this safety system reliable enough to prevent injury?”

Comprehensive Coverage: The library includes data for the entire TwinSAFE ecosystem, from EL series EtherCAT Terminals to integrated safety in AX5000 servo drives. How to Use the Beckhoff SISTEMA Library
In the era of Industry 4.0, safety should not be a static sticker—it should be a living calculation. With the Beckhoff Sistema Library, it finally is.

This manual offers a compilation of sample applications, hardware interconnections, and mapping within safety projects using pre-certified function blocks. It is available via the Beckhoff TwinSAFE Project Design page. The is a digital data collection provided by
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. Step-by-Step Guide: How to Use the Beckhoff SISTEMA Library
If you are currently engineering a system with TwinSAFE terminals, downloading the latest SISTEMA library is the single best step you can take to guarantee a safe, compliant, and well-documented automation system.
Locate the downloaded Beckhoff .slb (SISTEMA Library) or .xml file to add the components to your local database.
Ensuring machinery complies with international safety standards is a critical requirement for modern automation engineers. To simplify this process, the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) developed SISTEMA. This widely accepted software tool helps engineers calculate the Performance Level (PL) of safety-related control systems according to ISO 13849-1.
