Log PLC data locally, trend historical values, and export clean CSV reports without sending plant data to the cloud.
No credit card · No internet required · Windows 10/11 (64-bit)
A historian is only useful if it records the values you care about and makes them easy to review later.
All readings stay on the Windows machine, so you can review process history without cloud hosting or internet dependency.
See how pressure, level, flow, temperature, or any other tag changed over time.
Export data for reporting, maintenance review, or offline analysis in Excel and other tools.
Log values from Ethernet and serial devices so the same historian works across your plant.
Correlate historical readings with alarm events so you can see what happened before and after a fault.
Perfect for air-gapped plants where cloud historians are not allowed or not practical.
Add a Modbus TCP or RTU device and confirm the tag list is reading live values.
Choose which tags to store and how often they should be written to the local database.
Open the historian viewer, zoom into the time range you need, and export CSV when you need to share the data.
