On-premise local historian
A single Factry Historian instance runs locally within the production site, collecting and storing data close to the machines. It can't be simpler.
It is a straightforward setup most common in single-site companies, or when the focus is on reliable local data collection without the need to share across multiple plants.
When it’s used
- For standalone factories without a corporate-wide historian strategy
- When production data must stay entirely on-premise (e.g. due to regulation, IT policies, or latency constraints)
- In cases where local operators, engineers and managers need fast, direct access to process data
- As a first step toward digitalization before scaling to multi-site or cloud architectures
Architecture
Factry Historian runs on a server or virtual machine inside the plant network.
Collectors interface directly with PLCs, SCADA, or other OT data sources.
All data is written and stored locally; there is no dependency on external networks.
Dashboards, reporting, and APIs are served directly from this local instance.

Functions used
- Collectors buffer data locally and write it into the on-premise historian database
- Users manage configuration and access dashboards directly from the same server
- [Optional] Integrations with local MES, ERP or lab systems can be made on-site
Benefits
- The site is not reliant on internet or WAN connectivity
- Low latency access to live and historical data
- Simple to manage: one installation, one site, one team
- Sensitive process data never leaves the factory network
- Good entry point for companies starting their Industry 4.0 journey
Considerations
- Scaling is limited to the capacity of the local server (storage, CPU, redundancy)
- Requires on-site IT/OT support for maintenance, backups and upgrades
- No built-in sharing of data across sites: each historian remains an island
Summary
A local on-premise historian deployment: simple, self-contained, and reliable. Ideal for single-site factories or as a first step before scaling to centralized or multi-tier architectures.
