The Role of the Beckhoff SISTEMA Library in Functional Safety Design
In the realm of modern industrial automation, the transition toward "smart factories" has heightened the importance of functional safety. As machines become more autonomous and complex, ensuring that control systems respond predictably to failures is critical for protecting human life and equipment. Central to this process in the European market and beyond is ISO 13849-1
, which provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems. To simplify the complex mathematical verification required by this standard, the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) developed
(Safety Integrity Software Tool for the Evaluation of Machine Applications). Beckhoff Automation supports this ecosystem by providing a free SISTEMA library
, which serves as a vital bridge between high-performance hardware and rigorous safety compliance. Simplifying Safety Calculations
The primary challenge in complying with ISO 13849-1 is the calculation of the Performance Level (PL)
. This involves evaluating various parameters, such as the Mean Time to Dangerous Failure ( cap M cap T cap T cap F sub d ), Diagnostic Coverage ( cap D cap C ), and Common Cause Failures ( cap C cap C cap F
). Manually calculating these for every component in a complex control loop is not only time-consuming but prone to human error.
Beckhoff addresses this by offering their safety component data in the standardized
(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 Getting the Beckhoff SISTEMA library for free is
The Beckhoff SISTEMA library is specifically designed to reflect the capabilities of the
system. TwinSAFE is Beckhoff’s integrated safety solution that utilizes the Fail Safe over EtherCAT (FSoE) protocol. Because TwinSAFE allows for distributed safety logic—meaning safety functions can be handled over the same network as standard control data—the architecture can become intricate.
The SISTEMA library allows designers to model these distributed architectures accurately. Whether a system uses a centralized safety PLC or distributed safety logic within I/O terminals, the library provides the building blocks to verify that the entire "safety chain"—from the sensor to the evaluation unit to the actuator—meets the required risk reduction target. Accessibility and Industry Standardization
A significant advantage of the Beckhoff SISTEMA library is that it is provided free of charge
. By removing the financial barrier to accessing safety data, Beckhoff promotes a culture of safety-first design among small and medium-sized enterprises (SMEs) that might otherwise struggle with the overhead of compliance.
Furthermore, Beckhoff’s commitment to the SISTEMA format aligns with a broader industry trend toward interoperability. Since many other component manufacturers (such as sensor or valve terminal providers) also provide free SISTEMA libraries, an engineer can build a complete, multi-vendor safety model within a single software environment. This "plug-and-play" approach to safety modeling significantly reduces "time-to-market" for new machinery. Conclusion
The Beckhoff SISTEMA library is more than just a data file; it is a critical tool for modern engineering. By providing free, validated reliability data for their TwinSAFE hardware, Beckhoff enables engineers to transition from theoretical safety concepts to documented, compliant machine designs with high efficiency. In an era where industrial complexity is soaring, such tools are indispensable for ensuring that technological progress does not come at the cost of human safety. the library into the SISTEMA software?
To obtain and use the Beckhoff SISTEMA library, follow this guide. The library is a free resource provided by Beckhoff to help engineers evaluate safety functions according to the DIN EN ISO 13849-1 standard. 1. Download the Library
You can download the latest version of the SISTEMA library directly from the Beckhoff TwinSAFE project design page.

Historical Versions: If you need older versions, they are often hosted on the Beckhoff download server. 2. Import into SISTEMA Software
Once you have the library file, you must import it into the SISTEMA utility (provided by the IFA - DGUV): Open the SISTEMA software. Navigate to the Library menu. The Software Library (TwinCAT) – Free: The
It sounds like you're looking for free libraries for Beckhoff TwinCAT (often searched with "sistema" due to Italian/Spanish influence, meaning "system").
Here’s the helpful breakdown:
Yes, the core Beckhoff library for controlling standard fieldbus devices, including Festo Sistema modules, is typically provided free of charge.
Here is the crucial distinction every engineer must understand:
The Software Library (TwinCAT) – Free: The .library file you import into TwinCAT 3 (e.g., Tc2_System, Tc2_IOFunctions, or specific Festo libraries) is included in the TwinCAT 3 ADS or TwinCAT 3 PLC environment without additional licensing fees. Beckhoff does not charge for the library itself.
The Runtime Licenses (TwinCAT) – Potentially Paid: While the library file is free, using it requires a valid TwinCAT runtime license on your Beckhoff hardware (e.g., CX series, C6015). If you are using the Engineering environment (TwinCAT XAE) in "Config Mode" or "Free Run," no license is needed. For deployed machines, you must purchase a license from Beckhoff, but this is not a fee for the library.
The Hardware (Festo) – Not Free: The library controls physical hardware. You still need to purchase the Festo valves, manifolds, and CPX terminals from Festo.
Conclusion: The library itself is legally free to download, use, and distribute as part of any TwinCAT installation.
False. Beckhoff uses a unique model: The software is free; the license is for the runtime on the hardware. You can download TwinCAT 3 from the Beckhoff website without any payment. All standard libraries come with it.
To use Tc3_Sistema in a real project:
While often used for reading, the library supports writing parameters. This allows for "on-the-fly" parameter changes.
To work effectively with the library, one must understand the underlying data structures:
ST_SISTEMA_PARA: A structure containing parameter information. It typically includes the parameter index, sub-index, data type, and value.E_SISTEMA_DATA_TYPE: An enumeration defining the data types (BOOL, INT, REAL, etc.) used to ensure type safety when reading/writing parameters.✅ Yes, it is completely free – no license key or activation required.
It is distributed as part of Beckhoff’s TcSistema package (downloaded via the TwinCAT Package Manager). There are no runtime fees, subscription costs, or hidden charges.
