The Beckhoff SISTEMA library is a critical tool for safety engineers, providing pre-calculated reliability data for components. This data is imported into the SISTEMA software
(Safety Integrity Software Tool for the Evaluation of Machine Applications) to calculate the Performance Level (PL) of a safety function according to DIN EN ISO 13849-1. 🛡️ Key Functions
Enables modeling of safety functions before or after realization. Reliability Data: Provides parameters like cap M cap T cap T cap F sub d cap B sub 10 d end-sub cap D cap C sub a v g end-sub for Beckhoff safety hardware. Validation:
Outputs the final achieved Performance Level (PL) to ensure regulatory compliance. 🚀 How to Use the SISTEMA Library Get the latest Beckhoff SISTEMA library file (usually ) from the Beckhoff website Open the SISTEMA software and use the Library Manager to import the Beckhoff file.
Drag and drop Beckhoff safety components (e.g., EL6910 logic, EL1904 inputs) into your safety function project. Calculate:
The software automatically uses the library's product data to calculate the overall system reliability. 🛠️ TwinSAFE & SISTEMA Integration
While SISTEMA is a separate calculation tool, it works hand-in-hand with engineering: TwinSAFE Logic: Program your safety logic in TwinCAT.
Validate that the hardware configuration meets the required PL (e.g., PL d or PL e). Documentation:
Use SISTEMA's generated reports as part of your machine's official safety file. Pro-Tips for Safety Engineering Always Check Versions:

Beckhoff SISTEMA Library: Comprehensive Integration Report Beckhoff SISTEMA Library
is a specialized collection of safety-related characteristic values provided by Beckhoff to facilitate the verification of safety functions in machinery. This library is designed for use within the
(Safety Integrity Software Tool for the Evaluation of Machine Applications) utility, which calculates reliability values and achieved Performance Levels (PL) in accordance with DIN EN ISO 13849-1 1. Overview and Purpose beckhoff sistema library
Modern machine safety requires rigorous calculation of safety integrity. The Beckhoff SISTEMA library simplifies this by providing pre-validated data for components. Modeling Capabilities
: Allows users to model safety functions before realization or evaluate them after implementation. Reliability Data : Contains essential parameters such as cap M cap T cap T cap F sub d (Mean Time To dangerous Failure), cap D cap C sub a v g end-sub (Average Diagnostic Coverage), and cap C cap C cap F (Common Cause Failure). Compliance : Supports the universal VDMA 66413
format, which ensures compatibility across different safety assessment tools. 2. Key Components Covered
The library typically includes data for Beckhoff's extensive safety portfolio:
: Digital and analog safety terminals (e.g., EL19xx, EL29xx series). Safety Controllers
: Dedicated TwinSAFE Logic components like the EL6910 or software-based controllers. Motion Control
: Safety-related drive functions for integrated motion solutions. 3. Integration Workflow

The Beckhoff SISTEMA library is a collection of safety-related parameters for Beckhoff components (like TwinSAFE I/Os and logic units) designed for use in the SISTEMA software. This tool allows engineers to evaluate the Performance Level (PL) of safety functions according to ISO 13849-1. 1. Downloading the Library
You can find the Beckhoff SISTEMA library files (typically with a .slb or .ssplib extension) through the following official channels:
Beckhoff Download Finder: Search for "SISTEMA" on the Beckhoff Download Finder to locate the latest safety data. The Beckhoff SISTEMA library is a critical tool
Direct FTP/Web Directory: Files are often hosted in the TwinSAFE documentation directory on Beckhoff's download server.
IFA Website: The IFA (Institute for Occupational Safety and Health) maintains a list of manufacturer libraries, though it often directs users to the manufacturer's own site for the latest versions. 2. Importing into SISTEMA
Once you have downloaded the file (usually a .zip containing the library): Extract the file to a local folder. Open SISTEMA software. Go to Library -> Local library in the menu.
Click Add library and browse to the extracted Beckhoff file.
Note: If you are using SISTEMA 3.0 or higher and have an older .slb file, you may be prompted to use the SISTEMA Library Version Converter to update the format. 3. Using the Library in Your Project
Select Components: After importing, you can search the library for specific Beckhoff terminals (e.g., EL1904 for safe inputs, EL2904 for safe outputs).
Modeling Safety Functions: Drag and drop the component into your SISTEMA safety function. The library automatically populates critical safety values like MTTFd, DCavg, and Category.
Reference Application Guide: For complex setups, Beckhoff provides a TwinSAFE Application Guide that includes sample calculations and hardware interconnections that have been pre-verified by TÜV SÜD. Commonly Used Safety Components Software: SISTEMA libraries - IFA - DGUV
Before writing a single line of code, draw your machine states (using FB_StateMachine) and your sequence steps (using FB_StepChain). This forces rigorous thinking about transitions, especially error paths.
Standard safety validation follows a disjointed process:
When you use the Tc2_Sistema blocks, TwinCAT automatically exposes rich diagnostic information. You can watch the active step index, the time remaining on the step timer, and the current machine state directly in the TwinCAT Runtime (System Manager). This is invaluable for commissioning.
