Proficy Historian is industrial software used to collect, archive, and analyze time-series data from production equipment, sensors, and control systems in manufacturing and utility environments. Engineered for high-speed, high-volume data environments, Proficy Historian enables organizations to capture and store process and production data efficiently and cost-effectively. It supports time-stamped data collection from a wide range of industrial devices and automation systems using standard protocols such as OPC UA, MQTT, and traditional data interfaces. Operations teams, engineers, analysts, and IT professionals use Proficy Historian to improve process visibility, troubleshoot equipment issues, and support data-driven decision-making. The software plays a central role in performance monitoring, quality analysis, and regulatory compliance by enabling long-term access to historical data and seamless integration with reporting and analytics tools. Proficy Historian is designed for deployment flexibility. It can be installed on-premise at a facility, deployed at the edge to support localized data capture and buffering, or integrated into a hybrid or cloud architecture to support enterprise-wide analytics and central data aggregation. This flexibility allows industrial organizations to adapt to modern data strategies while maintaining continuity with existing infrastructure. Key capabilities include: • High-performance compression and storage of time-series industrial data to reduce infrastructure load • Support for distributed, edge, and cloud-connected architectures to align with evolving data strategies • Secure, scalable data collection from multiple sources across plants, lines, or remote assets • Integration with visualization and analysis tools, including Excel plug-ins and analytics platforms • Redundancy, filtering, and data quality features to ensure consistent, reliable data access Proficy Historian is used across industries such as power generation, food and beverage, chemicals, oil and gas, and water/wastewater. It provides a reliable foundation for industrial data management strategies, enabling manufacturers and utilities to gain insight into operations, optimize performance, and meet compliance and reporting requirements over time.
