Beckhoff SISTEMA Library is a free data package provided by for use with the SISTEMA software tool

. It is not a TwinCAT PLC library for programming, but rather a safety characteristics database

used to calculate and verify the Performance Level (PL) of safety functions according to the DIN EN ISO 13849-1 Beckhoff Automation Key Features Standardized Format : The data is provided in the VDMA 66413

format, which is a universal neutral interface for safety-related characteristic values. Comprehensive Data : It includes reliability values (e.g., cap M cap T cap T cap F sub d cap B sub 10 d end-sub ) for Beckhoff

components, such as EL69xx safety logic terminals, EL19xx digital inputs, and EL29xx digital outputs. Seamless Integration

: Once imported into SISTEMA, you can drag and drop Beckhoff components into your safety function model to automatically calculate the total Performance Level. Beckhoff Automation Review: Strengths and Weaknesses download/document/automation/twinsafe/SISTEMA - Beckhoff Overview

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

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. Key features

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?

False. Beckhoff provides free technical support for all libraries included in the TwinCAT installation. You can contact Beckhoff support (during the warranty period of your hardware) for help with Tc2_System.

  • Version Consistency: Because the data is embedded in the function blocks within TwinCAT, it ensures that the safety calculation matches the specific version of the hardware and firmware being used in the project, reducing the risk of "version mismatch" errors during audits.

    • Programmable safety systems are migrating from dedicated safety PLCs to integrated environments like Beckhoff TwinCAT 3. The Tc3_Sistema library (Sistema = Sicherheitstechnisches System - Safety Technology System) allows standard TwinCAT developers to write safety application code using Function Block Diagrams (FBD) or Structured Text (ST) in the same environment as non-safe logic.

    Problem Statement: Many engineers ask: "Is the Beckhoff safety library free, or does it require a paid license?"
