The OPC UA DA Server per client Honeywell CV-OPCUDA is a specialized software license that enables OPC UA Data Access (DA) server functionality within the PlantCruise automation platform, operating on a per-client basis. This license is essential for systems requiring standardized data exchange with external clients using the OPC UA protocol, which has become the industry standard for secure and reliable interoperability. The implementation of the HONEYWELL CV-OPCUDA allows the PlantCruise system to act as a comprehensive data server, making real-time process information, historical data, and alarms available to authorized third-party applications such as Manufacturing Execution Systems (MES), enterprise resource planning (ERP) systems, and custom analytics platforms.

A critical technical aspect of the CV-OPCUDA OPC UA DA Server per client is its resource requirements, which must be carefully considered during system design. For every 1,000 points exposed through the OPC UA server, an additional 150 MB of RAM is recommended to ensure optimal performance. The server itself should run on a robust platform, typically a quad-core processor with a clock speed of 2.0 GHz or higher, to handle the computational load of data encoding, security management, and client connections. The Honeywell CV-OPCUDA OPC and Data Exchange is designed for PlantCruise R500 and later versions and requires a batch manager license (CV-BATCHMGR) as a foundation, with its underlying database leveraging SQL Server 2019 or a compatible version.

The functionality provided by the Honeywell CV-OPCUDA is distinct from other connectivity options included in the base PlantCruise database license, such as the DNP3 interface. While base licenses cover fundamental connectivity, it specifically expands the system's capability to serve data to modern OPC UA clients, each connection representing a Client Application Instance (CAI). This per-client licensing model provides scalability, allowing plants to purchase exactly the number of concurrent external connections needed for their operational and enterprise integration requirements.

In summary, the Experion LX parts Honeywell CV-OPCUDA is a crucial enabler for Industry 4.0 and digital transformation initiatives within process plants. By implementing it, organizations can securely bridge the gap between the operational technology (OT) environment of the control room and the information technology (IT) systems that drive business decisions. This license ensures that critical process data flows seamlessly and securely across the enterprise, supporting advanced analytics, centralized monitoring, and improved operational intelligence.
