Beckhoff Sistema Library =link= -

Beckhoff SISTEMA Library is a digital product database used by engineers to calculate and verify the safety of machine control systems. It is designed specifically for use with

• sDesignation: Component name.
• eCategory: The structural category (B, 1, 2, 3, or 4).
• rMTTFd: Mean Time To Dangerous Failure.
• eDC: Diagnostic Coverage.
• nChannels: Number of channels (single vs. dual channel).

Safe Automation with TwinSAFE (Whitepaper): A comprehensive guide on distributed safety architectures, CAD integration, and runtime customization using the TwinSAFE Loader. beckhoff sistema library

While the SISTEMA library is used for external safety verification, Beckhoff’s TwinSAFE system handles the actual implementation of safety logic. The TwinSAFE application guide provides a collection of pre-certified samples that can be paired with SISTEMA calculations to speed up the certification process. Beckhoff SISTEMA Library is a digital product database

Example check in code:

// Decision logic bMachineAllowed := (eStopResult.PL >= rRequiredPL) AND eStopResult.Valid; sDesignation : Component name

Beckhoff has done the heavy lifting of TCP/IP synchronization and election logic. Your job is simply to decide what data to synchronize and when to hand over the keys.

• TwinCAT Runtime: deterministic task scheduling, real-time kernel, PLC and NC runtimes.
• Core Libraries (TcCOM, TcBase, TcSys, etc.): base services, data type mappings, error handling.
• Fieldbus & Protocol Libraries: EtherCAT master, PROFINET, EtherNet/IP, CANopen, OPC UA stacks.
• Motion & Robotics Libraries: NC PTP/Continuous, coordinated multi-axis motion, interpolation, camming.
• Device and I/O Libraries: driver wrappers and device descriptions for Beckhoff EtherCAT Terminals and other I/O families.
• System and Diagnostics Libraries: logging, time synchronization (PTP), safety integration (TwinSAFE), and redundancy.
