Drag and drop the corresponding Beckhoff input terminal (e.g., EL1904) into the block.
or use the "Add Library" button to select the downloaded Beckhoff file. Build Your Safety Function beckhoff sistema library
: Drag and drop Beckhoff components (like TwinSAFE terminals) from the library into your safety function project to automatically populate reliability values. Integration with TwinSAFE
Modern machine safety requires rigorous calculation of safety integrity. The Beckhoff SISTEMA library simplifies this by providing pre-validated data for components. Modeling Capabilities stConfig
The library covers EtherCAT safety terminals (EL series) and EtherCAT Plug-in Modules (EJ series), including:
Once the Beckhoff components are assigned to their respective channels, SISTEMA will automatically calculate the overall Performance Level of your system. If the green checkmark appears, your system satisfies the target safety requirements. You can then export the final documentation as a PDF report for your machine's technical file. Best Practices for TwinSAFE Evaluation If the green checkmark appears, your system satisfies
Remember to also download SISTEMA libraries for 3rd-party sensors (light curtains, e-stops) used with Beckhoff I/O. Automation: TwinSAFE Loader
: Access the Beckhoff Download Finder or the SISTEMA directory and download the .xml or .slb library files. Import to SISTEMA : Open the SISTEMA software on your PC. Navigate to Edit > Libraries .
In the world of industrial automation, the complexity of machine programming has grown exponentially. Modern machines are no longer collections of independent cylinders and motors; they are highly interdependent systems requiring state management, error handling, and coordinated motion. While standard PLC programming (using TIA Portal, RSLogix, or TwinCAT’s standard libraries) provides the building blocks, managing large-scale applications often leads to monolithic, hard-to-debug code.
SISTEMA automatically aggregates the data. It checks if the safety chain meets the Required Performance Level ( PLrcap P cap L sub r ) specified by your machine risk assessment. Key Benefits for Engineers
