Historical Replay

See What Actually Happened Not What Someone Remembers

When something goes wrong on the floor, the first question is always 'what happened?' Sandhed's Timemachine lets you scrub back to any moment and see your entire facility exactly as it was.

The Problem

Where Things Break Down

When an incident happens on the floor, the investigation starts with questions and ends with guesswork. Operators remember things differently. Log files are scattered across systems. By the time someone pulls the data together, the details are fuzzy and the timeline has gaps. Shift handoffs lose context because there is no record of what actually happened, only what someone thought to write down. Compliance audits are worse. Auditors ask for proof of conditions at a specific time, and your team spends days collecting screenshots, exporting CSVs, and stitching together a timeline from fragmented sources.

Incident investigations rely on memory

When something goes wrong, the first step is asking people what they saw. Different operators give different accounts. The actual sequence of events gets lost because nobody can replay what the equipment was doing at that exact moment.
Days to reconstruct a single incident timeline

Compliance audits require manual evidence collection

Auditors want proof that conditions were within spec at a specific time. Your team exports data from PLCs, pulls logs from SCADA, and screenshots from HMIs. Assembling a complete picture for one audit finding can take a full day.
8+ hours per audit finding for evidence collection

Shift handoffs lose critical context

The outgoing shift tries to communicate what happened in 5 minutes at the board. Equipment issues that developed slowly get summarized or forgotten. The incoming shift starts without knowing what to watch.

Our Approach

What Sandhed Does Differently

Sandhed records every machine state change, sensor reading, alert, asset position, door event, and work order status continuously. The Timemachine lets you scrub back to any point in time and see your 3D floor plan exactly as it was at that moment. Machines show their actual status. Assets appear where they were. Alerts that were active are visible. You can play events forward at 2x, 5x, or 10x speed to watch how a situation developed. Event markers on the timeline highlight state changes and alerts so you can jump directly to the moments that matter. For longer time ranges, data is automatically aggregated so you can review a full week or month without waiting for raw data to load.

Full State Reconstruction

Scrub to any timestamp and see every machine's operational status, sensor readings, and position exactly as they were. The 3D floor plan rebuilds the complete state including active alerts, door positions, and work order status.

Timeline with Event Markers

A visual timeline bar shows colored markers for alerts and state changes within your selected time range. Hover to see event details, click to jump directly to that moment and zoom to the affected asset.

Variable-Speed Playback

Play events forward at 0.5x to 10x speed to watch how a situation developed over time. See machines transition between states, alerts trigger and resolve, and assets move through your facility in accelerated replay.

Smart Data Aggregation

For short time ranges you get raw sensor data. For longer periods the system automatically switches to 15-minute, hourly, or daily aggregates. You can review a full month of operations without waiting for millions of raw data points to load.

FAQ

Common Questions

By default, the Timemachine stores a full year of historical data. Your organization can configure a custom start date if you want to restrict how far back users can browse. The system stores all machine states, sensor readings, alerts, asset positions, door events, and work orders continuously.

Everything you see in the live view is reconstructed in the Timemachine: machine operational states (running, idle, warning, error, maintenance), sensor metrics (temperature, OEE, cycle time), asset positions from RTLS tracking, active alerts, door states (open, closed, locked), and work order status with milestone timestamps.

No. The Timemachine runs in a separate mode indicated by an amber banner at the top of the screen. Your live monitoring, alerts, and dashboards continue to operate normally. You can switch between live and historical views instantly.

Data is automatically downsampled based on the time range you select. Ranges under 1 day show raw sensor data. 1 to 7 days uses 15-minute aggregates. 7 to 30 days uses hourly aggregates. Over 30 days uses daily aggregates. This keeps the interface responsive regardless of the time window.

Yes. You can navigate to any specific timestamp an auditor asks about and show the complete facility state at that moment. Machine conditions, sensor readings, alert status, and maintenance activity are all visible. This replaces the manual process of exporting data from multiple systems and assembling evidence.
