Beckhoff Sistema Library -

The Beckhoff Sistema Library (often referenced under the TwinCAT 3 function Tc3_Sistema ) is a software library that allows safety engineers to perform and Safety Integrity Level (SIL) calculations directly within a Beckhoff TwinCAT 3 project.

Drag the appropriate Beckhoff input module (e.g., EL1904) from the library into the Input block of your SISTEMA safety function.

If the Leader crashes, is unplugged, or loses power, the Follower detects the heartbeat loss within milliseconds and takes over seamlessly.

The Sistema Library is based on the IEC 61508 standard, which provides a framework for the development of functional safety systems. By leveraging the Sistema Library, engineers can create safety-related control systems that meet the stringent requirements of various industries, including automotive, aerospace, and process industries.
