Imagine designing a complex safety matrix. You need an E-Stop, a light curtain, and a safety door interlock, all feeding into a safe speed monitor. With the Sistema Library integration, you drag these blocks into your TwinCAT project. When you are ready to validate the system, you don't open a separate PDF to look up failure rates. Instead, TwinCAT can export the configuration directly into a SISTEMA project file.
Because the library blocks are pre-certified, SISTEMA instantly recognizes them. It pulls in the failure probabilities, the diagnostic coverage, and the architectural constraints. What used to be days of data entry becomes a near-instantaneous validation. beckhoff sistema library
For every FB_Step, set a realistic tMaxTime. If a pneumatic cylinder takes 0.5 seconds normally, set the timeout to 1 second. If it exceeds that, the library will call the onTimeout method where you can trigger an alarm and abort the sequence. This turns intermittent mechanical issues into diagnosable faults.

To get the most out of Tc2_Sistema, follow these guidelines: Limitations & Considerations
The library is pre-certified by IFA. Using it ensures that your calculation methods comply with:
While developed by Beckhoff, the library exports data for the SISTEMA tool, which is a vendor-neutral standard (developed by IFA). This allows Beckhoff systems to be seamlessly integrated into safety calculations that include non-Beckhoff devices (e.g., a third-party safety laser scanner paired with a Beckhoff PLC), provided the third-party data is entered manually into the TwinCAT logic blocks.
