ISO 13849 Control Performance Level (PL) Estimator

Estimate the overall safety Performance Level (PL a to e) of mechatronic controls systems according to Category architecture, MTTFd, and Diagnostic Coverage.

Purpose & Calculation Breakdown (India)

Purpose of this Tool: Verify control safety system compliance by aligning device architecture structures with probabilistic hardware reliability metrics.

• Safety Performance Level Mapping Matrix:\text{Category Structure} + \text{MTTF}_d \text{ (Years)} + \text{Diagnostic Coverage (DC)} \rightarrow \text{Estimated PL}
