About Performance Level (PL) Calculation with SISTEMA

This event covers the compliance, engineering, and verification requirements defined by Performance Level (PL) Calculation with SISTEMA.

SISTEMA is the IFA's free software tool implementing ISO 13849-1 mathematics: modeling safety functions as subsystem chains and computing achieved PL from Category, MTTFd, DCavg and CCF inputs, replacing error-prone manual lookup of Annex K tables.

What it regulates

Practical PL verification workflow: structuring functions into input-logic-output subsystems, importing manufacturer component libraries, entering mission time and diagnostic data, and generating the documentation for the technical file.

Who must comply

Machine safety engineers verifying PLr achievement; component suppliers publishing SISTEMA libraries for their devices.

Key requirements of Performance Level (PL) Calculation with SISTEMA

  • Project structure: safety function, subsystems, channels/blocks, elements
  • Component libraries with manufacturer PL/B10d/MTTFd data
  • Automatic computation of channel MTTFd (parts-count), DCavg weighting, and PL with PFHd
  • Report generation for validation evidence

Key concepts: Performance Level (PL) Calculation with SISTEMA

B10d
For electromechanical parts, the cycle count at which 10 percent fail dangerously — converted to MTTFd via actual operation rate (nop).
nop
Annual operation count derived from usage assumptions (days, hours, cycle time) driving wear-based reliability.
Parts-count method
Summation of element failure contributions to a channel's MTTFd, capped at 100 years per channel.
PFHd
The computed average probability of dangerous failure per hour mapped to the PL bands.

Frequently asked questions: Performance Level (PL) Calculation with SISTEMA

Is a SISTEMA report sufficient validation?

It evidences the quantitative leg. Full validation per ISO 13849-2 still needs functional and fault-injection testing, software verification, and confirmation of CCF measures and application assumptions.

Why does SISTEMA cap MTTFd at 100 years?

ISO 13849-1 caps the per-channel MTTFd credit at 100 years (2015 edition) to keep claims within the method's calibration; better components then improve robustness margin, not the computed PL.
