Safety functions, required Performance Levels / SILs and verification — EN ISO 13849-1 (PL-first) with optional EN 62061 (SIL)
Identify the machine, then choose how safety functions are verified: a full in-tool assessment, or external verification in SISTEMA (upload the project + report instead).
Please sign in — assessments save automatically to the cloud.
💡 SISTEMA mode hides the per-function register — attach the SISTEMA project file and verification report below instead. Switching modes keeps the other mode's data.
EN ISO 13849-1 (PL) is always assessed. Tick this to add SIL targets, hardware-fault-tolerance and systematic-capability fields per function.
Describe your machine and let AI draft a safety-function list with PLr starting points and architecture hints. You review everything before anything is applied — manual entries are never overwritten.
Attach the SISTEMA project and its verification report. The report records this section as externally verified — the browser never recalculates SISTEMA results; a competent person must verify the contents inside SISTEMA.
No files attached yet.
Lifecycle prompts per EN ISO 13849-1 Ch. 10 / EN 62061 Ch. 6–7, plus the validation plan and sign-off. Applies to the native register above.
Review and export your PL/SIL assessment. Incomplete functions are flagged, never hidden.
