This article explores what the Beckhoff SISTEMA library is, why it is essential for machine builders, and how you can leverage it to streamline your safety evaluations. What is the Beckhoff SISTEMA Library?
: Like many manufacturer libraries, you must manually check the Beckhoff website to ensure you have the latest version. Using an outdated library may result in calculations that don't reflect current hardware revisions.
The is a free data package that allows you to import Beckhoff-specific safety component data directly into the SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications) utility. This tool is essential for evaluating machine safety functions and calculating Performance Levels (PL) according to DIN EN ISO 13849-1 .

Once imported, applying these components to a safety function evaluation follows a structured workflow: 1. Define the Safety Function
The Beckhoff SISTEMA library is a free, downloadable data file containing all the safety-relevant technical parameters for Beckhoff’s TwinSAFE and standard automation components. Instead of hunting through PDF datasheets for safety values, you simply import this library directly into SISTEMA. The library includes pre-configured safety data for:
Beckhoff provides its SISTEMA libraries completely free of charge. No software licenses or active maintenance contracts are required to access them. Step-by-Step Download Instructions Visit the official website. Safety functions require an Input, a Logic processor,
Once external field devices (such as physical E-stop buttons or contactors) are added to the loop alongside the TwinSAFE hardware, SISTEMA will automatically compute the total . Compare this against your Required Performance Level ( PLrcap P cap L sub r ) determined during your initial machine risk assessment. Troubleshooting Common Issues "Library File Format Not Supported"
When your architecture is complete, SISTEMA generates a comprehensive PDF safety report. Because you used official, pre-verified Beckhoff library data, your final report serves as clean, audit-ready documentation for safety inspectors, clients, and regulatory bodies. Summary of Benefits
The library is typically bundled as a .slb (SISTEMA Library) file or contained within a compressed .zip archive labeled "SISTEMA libraries for TwinSAFE components".
(SISTEMA Library) format. This library contains the "safety-related reliability values" for their TwinSAFE components, including digital inputs, outputs, and logic terminals. By importing the Beckhoff library into the SISTEMA software, engineers can simply select the specific hardware they are using, and the software automatically populates the necessary reliability data. This automation ensures that the final PL calculation is based on manufacturer-validated data. Integration with TwinSAFE What is the Beckhoff SISTEMA Library
Adding a reference to the library makes its entire suite of powerful functions available for your program.
SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications) is a free software utility developed by the IFA (Institute for Occupational Safety and Health of the German Social Accident Insurance). It is recognized globally as the standard tool for calculating the achieved Performance Level (PL) of safety-related parts of control systems.
