30+ Years of Automation Excellence



OPC HDA (Historical Data Access) is a specification for communication between industrial control systems and data historians. It provides a standardized way for industrial applications to store and retrieve time-series data, such as process data, events, and alarms. OPC HDA enables industrial applications to archive and analyse large amounts of data, allowing for improved process control and decision making. The specification was developed by the OPC Foundation, an organization dedicated to creating open standards for industrial automation and information exchange. OPC HDA is designed to work with other OPC specifications, such as OPC UA and OPC DA, providing a unified and interoperable solution for industrial automation systems. With OPC HDA, industrial control systems can benefit from improved data management and historical analysis, leading to enhanced efficiency and performance.
