The primary resource for "Beckhoff SISTEMA library" is the official component library provided by Beckhoff for the SISTEMA software utility (Safety Integrity Software Tool for the Evaluation of Machine Applications). This library contains safety-relevant product data needed to calculate Performance Levels (PL) under DIN EN ISO 13849-1. Key Documentation & Downloads
SISTEMA Library Files: You can download the component data in .slb or .zip format directly from the Beckhoff TwinSAFE Project Design page.
Application Guide: The TwinSAFE Application Guide provides step-by-step examples for calculating safety parameters using these libraries. beckhoff sistema library
VDMA 66413 Standard: Beckhoff provides data in the VDMA 66413 universal database format, which is compatible with SISTEMA and other safety assessment tools. How to Use the Library
Import: Open SISTEMA and use the "Library" menu to import the downloaded Beckhoff .slb file. The primary resource for "Beckhoff SISTEMA library" is
Modeling: Select specific Beckhoff components (e.g., EL1904, EL2904) to automatically pull in their MTTFd, DCavg, and PFH values.
Calculation: The tool calculates the final PL for your safety function based on the components selected from the library. Where to Find Help It ensures that the safety validation is based
Beckhoff Information System: For technical manuals on TwinSAFE hardware, search the Beckhoff Information System.
IFA SISTEMA List: You can also find the latest manufacturer library links on the IFA Website. Software: SISTEMA libraries - IFA - DGUV
It ensures that the safety validation is based on the actual programmed configuration. If the hardware changes in TwinCAT, the export changes accordingly, alerting the safety engineer that recalculation is necessary.
The library typically consists of several function blocks designed to handle different levels of the safety architecture:
FB_SISTEMA_SafetyFunction: A higher-level block used to group components into a complete safety function (e.g., "Emergency Stop Stop Category 0").
