See how equipment actually operated, before explaining why.
Reconstruct state time, distribute load exposure, measure declared-limit excursions, and screen rapid changes from pasted historian or log data. Everything runs locally in your browser.
Machine State Log Analyzer
Reconstruct runtime, state duration, starts, exits, and transitions from timestamped state changes.
02 · LoadEquipment Load Profile Analyzer
Convert equally spaced readings into hours and share by load band.
03 · LimitsThreshold Excursion Duration Analyzer
Group below- and above-limit readings into duration-based events.
04 · DynamicsProcess Variable Rate-of-Change Screener
Find timestamp intervals that exceed declared rise or fall rates.
Four independent questions.
The state analyzer interprets categorical changes; the load tool builds a time-at-load distribution; the excursion tool measures residence outside user-supplied limits; and the rate screen evaluates change per elapsed time. None diagnoses a fault, estimates remaining life, changes a control-system alarm, or authorizes operation.
Keep the source boundary visible.
Export timestamps with time zone and units, preserve missing-data flags, and record the active equipment mode and limit revision. A clean calculation cannot repair a logger gap, a stale sensor, or a limit applied to the wrong operating state.
