DF-07Foundational
Automated Data Quality Control
Continuously checks incoming data for stuck sensors, impossible values, missing periods and broken units, and reports the field’s data health as a number.

In one sentence
Gets the live sensor data out of the control system safely and stores it at full resolution, which almost nothing else on this site does.
The problem
Control system historians are sized for operations, not analytics: they compress aggressively, keep months rather than years, and are often on hardware nobody wants to add load to. Meanwhile every predictive capability needs years of full-resolution history.
How it works
Collection is read-only and unidirectional from the OT network, through a DMZ and where required a data diode, following IEC 62443 zone and conduit principles. Data lands in a time-series database sized for years at full resolution, with store-and-forward buffering at the edge so a WAN outage delays delivery rather than losing data.
Data required
- Read-only access to OPC-UA, OPC-DA or the historian API, agreed with the control system owner
- Network path through the DMZ with firewall rules defined
- Tag list with engineering units, ranges and descriptions
- On-premise storage sized for the retention target
What you get
- Full-resolution time-series store with years of retention and fast query
- Tag catalogue with units, ranges and data-quality statistics
- Buffered edge collection that survives network outages without data loss
What it cannot do
History that was never recorded cannot be recovered: if the existing historian compressed to a dead band for ten years, that is the history you have, and full-resolution data begins on the day collection starts. Tag descriptions in most control systems are inconsistent and incomplete, and building a usable tag catalogue is a manual effort that usually surprises the project plan.
Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
