Introduction to Beckhoff and TwinCAT
Beckhoff Automation is a leading global provider of automation technology, renowned for its innovative products and solutions in the fields of industrial automation, process control, and building automation. One of the key software components of Beckhoff's automation solutions is TwinCAT, a comprehensive software platform for the development and implementation of automation projects.
What is TwinCAT?
TwinCAT (Twin Control) is a software system developed by Beckhoff that enables users to create and execute automation projects on various hardware platforms. TwinCAT provides a comprehensive range of functions for programming, testing, and commissioning of automation systems. With TwinCAT, users can create PLC (Programmable Logic Controller) projects, configure HMI (Human-Machine Interface) applications, and implement motion control and process control solutions.
Key Features of TwinCAT
Some of the key features of TwinCAT include:
Beckhoff System Library Free
The Beckhoff System Library Free provides users with a range of pre-developed function blocks and tools to speed up the development of automation projects. The library includes various components, such as:
By providing a comprehensive software platform and a range of free libraries and tools, Beckhoff's TwinCAT and System Library Free enable users to efficiently develop and implement automation projects, reducing development time and costs. beckhoff sistema library free
The Beckhoff SISTEMA library is a free data resource provided by Beckhoff to help engineers evaluate the functional safety of machine control systems using the SISTEMA software. What is the Beckhoff SISTEMA Library?
The library contains essential safety-related reliability values—such as MTTFdcap M cap T cap T cap F sub d B10dcap B sub 10 d end-sub
, and diagnostic coverage—for Beckhoff TwinSAFE components. Instead of manually entering technical data from catalogs, users can import this library to "drag and drop" components directly into their safety calculations, significantly reducing errors. Where to Download the Library for Free
Beckhoff provides these libraries at no cost through their official support and download channels.
Official Beckhoff Download Link: You can find the latest SISTEMA library files (often in .slb or .ssllib formats) in the Beckhoff SISTEMA Download Directory.
Beckhoff Download Finder: Use the Download Finder and search for "SISTEMA" to access updated version lists and documentation.
IFA DGUV Repository: As SISTEMA is maintained by the Institute for Occupational Safety and Health (IFA), they also host a collection of manufacturer libraries, including Beckhoff's. How to Use the Library in SISTEMA
Download and Extract: Download the ZIP file from the Beckhoff directory and extract the library file to a local folder. Import to SISTEMA: Open the SISTEMA software.
Go to the "Library" menu and select "Local library" or "Import".
Navigate to your extracted Beckhoff file to add it to your permanent repository. Model Your Safety Function: Create a new project or safety function (SF) in SISTEMA.
Identify the Beckhoff components used (e.g., EL1904 safe input terminal or EL6910 TwinSAFE Logic).
Drag these from the library into your project to automatically populate the performance level (PL) and reliability data. Why Use the Beckhoff SISTEMA Library?
Compliance: Simplifies verification of ISO 13849-1 standards for machine safety.
Accuracy: Uses manufacturer-certified data, ensuring your Performance Level (PL) calculations are valid.
Efficiency: Saves hours of manual data entry for complex TwinSAFE systems with multiple I/O points. TwinSAFE project design | Beckhoff Worldwide

The Beckhoff SISTEMA Library is a specialized, free-to-download data collection that simplifies the safety evaluation of machine control systems. It is designed for use within SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications), a widely used tool for calculating the safety Performance Level (PL) of machines according to the DIN EN ISO 13849-1 standard. What is the Beckhoff SISTEMA Library?
In functional safety engineering, you must prove that your safety-related control system meets specific reliability requirements. Instead of manually entering technical data for every Beckhoff component, you can import the SISTEMA library.
Component Data: Contains pre-calculated safety characteristic values (such as MTTFdcap M cap T cap T cap F sub d , B10dcap B sub 10 d end-sub , and PFHcap P cap F cap H ) for Beckhoff's TwinSAFE and standard I/O products.
Automation: Eliminates manual data entry errors by providing a "drag and drop" library of safety-certified blocks for hardware components.
Compatibility: The library is compatible with all versions of the SISTEMA software, including the latest SISTEMA 3.x. How to Access and Use the Library
Beckhoff provides these safety libraries free of charge as part of their commitment to the TwinSAFE ecosystem. Software: SISTEMA libraries - IFA - DGUV
The Beckhoff SISTEMA Library is an essential, free tool for engineers using the SISTEMA software (Safety Integrity Software Tool for the Evaluation of Machine Applications) to calculate the Performance Level (PL) of safety-related control systems. Overview & Utility
Instead of manually entering complex safety parameters for every Beckhoff component—such as MTTFdcap M cap T cap T cap F sub d (Mean Time to Dangerous Failure), B10dcap B sub 10 d end-sub
values, or diagnostic coverage—you simply import this library into the SISTEMA utility. It covers a vast range of Beckhoff’s safety portfolio, including TwinSAFE modules, digital I/O, and drive technology. Key Benefits Beckhoff System Library Free The Beckhoff System Library
Time Efficiency: It eliminates the need to hunt through datasheets for reliability values. You can drag and drop components directly into your project architecture.
Accuracy: Since the data is provided directly by Beckhoff, it ensures your safety calculations comply with ISO 13849-1 standards without manual entry errors.
Zero Cost: The library is provided as a free download, typically in .slib or .vslb formats, making it accessible for any project size.
Comprehensive Coverage: It includes data for standard components used in safety functions, not just dedicated "Safety" modules, which is vital for calculating the entire safety chain. Potential Drawbacks
Update Frequency: 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.
SISTEMA Specific: This library is built specifically for the IFA’s SISTEMA tool. If you are using a different safety calculation suite, you may need to convert the data or look for SISTEMA-compatible imports. How to Get It
