Performance level (PL)

You might say: safety integrity

Performance Level (PL) is a discrete reliability level for a safety-related control function, from PL a to PL e.

What it does

Sets the required architecture, diagnostic coverage, and reliability evidence for that safety function.

Ask

What required performance level (PLr) did the risk assessment assign to each safety function?

Typical

The required performance level (PLr) is determined for each safety function by the risk assessment.
