protection_tms_preview

Purpose and availability

Read-only arithmetic preview for changing only a backup IDMT relay time multiplier from a verified receipt. It does not recommend settings, run a study, write a project, establish device suitability, or provide engineering approval.

Before invocation

Inspect the current definition and exact version/project binding before invoking. Required fields, enums, bounds and consent fields below are authoritative. Omit no required input and do not invent unavailable values.

Results, errors and safety

Inspect the structured result and retained IDs/artifacts. Errors, unsupported profiles, missing data and cancellation remain explicit. A successful call grants no human engineering approval. Do not retry inference automatically. See Workflows, History and Project tools.
