Safety profile
German: Sicherheitsprofil
In functional safety and systems engineering, a safety profile is the set of active safety assumptions, permissions, limits and protective functions for a defined operating context. Switching the context switches the profile as a whole.

- German source term
In one sentence
A safety profile bundles the active safety limits, permissions and protective functions for one operating context, such as maintenance or reduced speed.
Example
An AGV uses one safety profile for open warehouse aisles (higher speed, large scanner fields) and another for a shared picking zone (reduced speed, smaller fields, audible warning).
How it applies
- Functional safety: Specify each profile completely: active safety functions, limits such as speed or zones, permissions and the assumptions it relies on.
- Switching: The selection of a profile is safety-relevant. Define how it is selected, how the switch is verified and what happens if no valid profile is active.
- Integrated systems: Profiles of neighboring machines must fit together, for example in a shared zone. Tie them to operating modes and zone states.
- Technical documentation: Operators need to know which profile is active and what it permits. Show it on the HMI and describe each profile in the manual.
- Evidence: Verify each profile separately, and verify the transitions between them.
