Keep the data on your machine

A historian is only useful if it records the values you care about and makes them easy to review later.

Local SQLite storage

All readings stay on the Windows machine, so you can review process history without cloud hosting or internet dependency.

Trend charts

See how pressure, level, flow, temperature, or any other tag changed over time.

CSV export

Export data for reporting, maintenance review, or offline analysis in Excel and other tools.

Modbus TCP + RTU

Log values from Ethernet and serial devices so the same historian works across your plant.

Alarm context

Correlate historical readings with alarm events so you can see what happened before and after a fault.

Offline operation

Perfect for air-gapped plants where cloud historians are not allowed or not practical.

How it works

  1. Connect your device

    Add a Modbus TCP or RTU device and confirm the tag list is reading live values.

  2. Enable historian logging

    Choose which tags to store and how often they should be written to the local database.

  3. Review and export

    Open the historian viewer, zoom into the time range you need, and export CSV when you need to share the data.
