WHAT IS PROFICY HISTORIAN?
Access your process and production data
Proficy Historian is a powerful process database designed for the collection, storage and distribution of large amounts of high-resolution process and production data. Time series and A&E data is collected from industrial data sources and stored securely and efficiently, with easy access for trending, analysis and reporting.
- Open interface: Data can be collected via OPC UA/DA, MQTT, ODBC, REST and XML/CSV, among others.
- One common source of process and production data across the business.
- Can be used “plant wide” across the facility, or “enterprise wide” across multiple facilities.

What prevents you from using data effectively?

Data silos
Production data is scattered across different systems that do not communicate. This makes it difficult to use data across systems and facilities, and hinders digitalisation.

Unstable data sources
Data from equipment and systems often has low resolution, variable quality or lack of history. This results in poor process understanding and makes troubleshooting difficult.

Slow data access
Other systems, such as SCADA, MES, ERP, analytics and dashboards, receive data late, in the wrong format, or via complicated integrations, creating slow reporting and inefficient workflows.

Low scalability
Traditional databases are unable to handle the growing amount of industrial data.

HOW DOES PROFICY HISTORIAN WORK?
Data collection, storage and distribution
Data collection at the millisecond level
Proficy Historian collects industrial data on edge, at high resolution, down to the millisecond level. Built-in security features ensure that critical data is never lost.
HOW PROFICY HISTORIAN HELPS:
Data is collected with complete and detailed information, ready for further use.
Get high-resolution process signals in real time, collected directly from sensors, PLCs, SCADA and other OT systems.
Data collection is done close to the source, via local collectors and open standards such as OPC UA/DA, MQTT, Modbus, REST and ODBC, among others.
Store & Forward technology caches data locally in the event of a network outage, ensuring that critical data is never lost.


Efficient and scalable storage
Proficy Historian uses advanced compression in the collector and before storage, and can store large amounts of data cost-effectively. The architecture is both scalable and deployable, and can handle increasing data volumes and multiple locations without performance degradation.
HOW PROFICY HISTORIAN HELPS:
Support for both time series and A&E data allows all history to be stored in the same database.
Powerful compression means that large amounts of data take up minimal storage space, without losing important process details.
Scalable architecture that handles 100 to 100 million tags per server.
Stable performance over time, even with increased data resolution, multiple data sources or facilities.
Distributed history allows data to be stored locally per facility, while also being available centrally.
Make data easily accessible
Proficy Historian makes stored data easily accessible across OT and IT environments, with high performance, open interfaces, and secure access control. It provides a common foundation for reporting, trending, analysis, and decision support.
HOW PROFICY HISTORIAN HELPS:
Secure deployment with role-based access control.
Fast access to both real-time and historical data via open APIs and standardized interfaces.
Seamless integration with SCADA, MES, ERP, BI tools, Analytics tools and other applications.
Visualization and trending through Proficy Operations Hub, with access to dashboards with trend curves and real-time analytics.

With Proficy Historian you get

Real-time data collection
Time series and A&E data are collected directly from equipment and systems down to millisecond resolution. Store & Forward technology ensures that data is never lost.

Efficient compression & storage
Advanced compression allows large amounts of data to be stored in a small space, without losing critical process details. You have years of high-resolution data readily available for analysis.

Secure access across IT & OT
One common source of data across the entire business: Real-time and historical data are readily available for use in MES, ERP, BI tools, and Analytics solutions.

From a facility to Enterprise scale
Proficy Historian is scalable and deployable, maintaining stable data flow and availability in complex industrial networks, from single plant to multisite environments.
A process database (such as Proficy Historian) is optimized for
continuous measurement data from sensors and production equipment. It handles high frequency, large data volumes, and time series compression.
A relational database (SQL) is designed for transactions , structured data, and table relationships. It is poorly suited for fast logging of high-resolution industrial signals. In production, they are complementary, but historical signal data should always reside in a Historian
How does Proficy Historian differ from other process databases?
Proficy Historian is designed specifically for industry, with millisecond resolution, lossy compression, enterprise architecture, A&E support, and collectors on edge, which sets it apart from general cloud-based time series databases.
Historian stores:
Time series data (real-time and historical)
– A&E data
– Calculated tags
– Metadata
This allows all process-related history to be collected in one place.
Historian supports role-based access, AD/LDAP integration, network segmentation, data-in-transit encryption, and secured API access. In addition, redundancy ensures data availability.
No. Historian does not replace SQL or other relational databases, it complements them. Time series data should reside in a Historian, while transactional data still belongs in relational databases.
Yes. Historian is designed to be vendor-agnostic and integrates easily with SCADA, MES, ERP, BI tools, and cloud-based analytics platforms via open APIs and standardized industry protocols.
Yes. Historian can run on-premise, hybrid or in the cloud. Many choose a combination of on-premises (for fast signals) and centrally in the cloud for enterprise analysis.
Proficy Historian is licensed based on the number of tags and feature level. There are options for both single-site and multi-site environments, including enterprise licenses. Contact us for more information.
A typical setup consists of one Historian server, collectors installed near the data sources, and integration with existing systems. Installation is quick, with many getting up and running within hours or a few days, depending on the project.
