ALSPA Optiplant OPC .Net API 1.0

ALSPA Optiplant OPC .Net API is a managed software development kit from ALSTOM that enables .NET developers to connect ALSPA OptiPlant and other OPC-compliant industrial data sources to custom applications. It streamlines access to real-time process values, alarms and events, and historical data (when supported by the underlying OPC server), making it easier to build HMIs, dashboards, analytics, and plant optimization solutions.

Key capabilities include:

• Browsing and discovery of the OPC address space
• Synchronous and asynchronous read/write operations with timestamps and quality
• Subscription-based updates with efficient change notifications
• Alarm and event handling, including filtering and acknowledgment when available
• Historical data queries if exposed by the server
• Robust connection management with error handling, retries, and diagnostics
• Documentation and sample code to accelerate development

Designed for industrial environments, the API promotes reliable, standards-based data exchange between ALSPA control systems and .NET applications, reducing integration effort while supporting interoperability within the OPC ecosystem.
