Beckhoff Sistema Library

In short, the Sistema library provides the function blocks necessary to synchronize two independent Beckhoff PLCs (a Leader and a Follower) so they act as a single logical unit.

The library consists of:

Pull the component into your project's safety function block. SISTEMA will automatically calculate the achieved beckhoff sistema library

Navigate to the section or search directly for "SISTEMA". In short, the Sistema library provides the function

The Beckhoff SISTEMA library bridges the gap between hardware application and regulatory compliance. By combining the flexibility of PC-based TwinSAFE control loops with automated safety calculations, automation professionals can design high-performance machinery that is fundamentally safe, reliable, and globally compliant.

: Some library entries might feature different configuration subsets (e.g., single-channel vs. dual-channel usage). Always select the library entry that mirrors how your hardware is wired in the electrical schematics. : Some library entries might feature different configuration

The library includes comprehensive data for the entire TwinSAFE ecosystem:

Once the safety logic is running, the library allows you to calculate dynamically based on:

Remember that ISO 13849-1 relies heavily on system architecture (Category B, 1, 2, 3, or 4). Even with certified Beckhoff components, your physical wiring and diagnostics deployment must match the designated Category requirements in SISTEMA.

Beckhoff provides a specialized library of function blocks—pre-written code modules—that are delivered with their SISTEMA parameter files. This creates a seamless handshake between the safety logic (the code) and the safety certification (the math).
