When the bLogThisHour trigger is activated at the top of the hour, the program would execute a series of steps, each leveraging a different block from the library:

She’d installed it months ago but never used it—a library of pre-certified safety function blocks, direct from the TwinCAT 3 Safety toolbox. “Sistema” wasn’t just a name; it was a reference to the EN ISO 13849-1 standard, the holy book of functional safety.

The 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

Unlike standalone SISTEMA, the Beckhoff library allows runtime adjustments based on maintenance cycles. For example, if a safety relay has exceeded its contact life expectancy, you can reduce the MTTFd value in the FB and recalculate PL in real-time.

Define your machine and the specific safety function you are evaluating (e.g., "E-Stop triggered safe shutdown").

To streamline this process, the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) developed (Safety Integrity Level and Performance Level Calculation Tool). To support this ecosystem, Beckhoff provides a dedicated, pre-built SISTEMA library . This library integrates Beckhoff TwinSAFE components directly into the software, drastically reducing engineering time. What is the Beckhoff Sistema Library?

The Beckhoff SISTEMA library is an essential resource for automation engineers. It bridges the gap between hardware design and safety certification by providing for TwinSAFE components. By enabling seamless integration with the SISTEMA software, the library automates complex PL calculations, ensures compliance with machinery safety standards, and reduces engineering errors. It is a key tool for any project requiring certified functional safety.
