Beckhoff Sistema Library May 2026

Beckhoff SISTEMA Library is a digital dataset provided by Beckhoff Automation to help engineers evaluate the safety of machine control systems. It is used within the SISTEMA software utility

(Safety Integrity Software Tool for the Evaluation of Machine Applications), which calculates reliability values and the achieved Performance Level (PL) according to DIN EN ISO 13849-1. Beckhoff Automation Key Features & Contents Reliability Data : Contains product-specific safety values (e.g., cap M cap T cap T cap F sub cap D cap B sub 10 cap D end-sub cap P cap F cap H sub cap D ) for Beckhoff safety-relevant components like terminals, logic modules, and safe drive technology. Pre-modeled Subsystems

: Allows users to import pre-defined blocks directly into SISTEMA projects, reducing manual entry errors. Broad Compatibility

: Covers the modular TwinSAFE portfolio, including digital inputs/outputs (EL1918, EL2911), safe motion (AX8000), and integrated logic. Beckhoff Automation How to Use the Library : Obtain the latest library file (typically a ) from the Beckhoff TwinSAFE Project Design page or directly from the Beckhoff Download Server Import to SISTEMA Open the SISTEMA software. Navigate to the Library Manager and select Add Library

Choose the downloaded Beckhoff file to integrate it into your local repository. Application

: Drag and drop the specific Beckhoff components into your safety function model to automatically populate the required safety characteristic values. Beckhoff Automation Availability and Support beckhoff sistema library

The Beckhoff SISTEMA Library is a digital data collection provided by Beckhoff to support machine safety evaluations using the SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications) utility. Purpose and Functionality Beckhoff SISTEMA Library is a digital dataset provided

Safety Evaluation: The library is used to model and evaluate safety functions under the DIN EN ISO 13849-1 standard.

Reliability Data: It contains product-specific reliability values—such as MTTFdcap M cap T cap T cap F sub d (Mean Time To Dangerous Failure), B10dcap B 10 d

, and diagnostic coverage—required to calculate the achieved Performance Level (PL) of a safety function.

Workflow Integration: Engineers import these manufacturer-provided libraries directly into the SISTEMA software to avoid manual data entry and ensure accurate safety calculations for TwinSAFE components. Access and Resources

Download: The library files (typically in .slb or .xml format) are hosted on the Beckhoff Download Server under the TwinSAFE documentation section. Mastering Safety and Efficiency: The Ultimate Guide to

TwinSAFE Context: While the SISTEMA library is used for offline calculation, the actual safety logic is developed within the TwinCAT environment using certified safety function blocks.

Support: Detailed technical information and manuals for Beckhoff products, including safety components, can be found in the Beckhoff Information System (Infosys). download/document/automation/twinsafe/SISTEMA - Beckhoff

Here’s a structured, critical review of the Beckhoff System library (Tc2_System) — which is often what users mean when they refer to the “sistema” library (from the Italian/Spanish word for “system”).

1.2 Key Components

The library consists of:

• Function Blocks (FBs): For calculating PLr (Required Performance Level) and PL (Achieved Performance Level).
• Data Structures: Predefined data types for safety components (e.g., light curtains, emergency stops, contactors).
• Diagnostic Coverage (DC) Helpers: Modules to calculate DC based on test rates and component architectures.

C. Ease of Documentation

The library facilitates the automatic generation of parts of the technical file required for CE marking and machinery directives. The exported data serves as a verified link between hardware and safety theory.
