OPC DA Server 5.22

OPC DA Server by ICS Triplex ISaGRAF Inc.

Description:
The ICS Triplex ISaGRAF OPC DA Server enables standards-based, real-time data exchange between ISaGRAF-based control applications and any OPC-compliant client, including HMI/SCADA systems, historians, and engineering tools. It exposes ISaGRAF variables and I/O points through the OPC Data Access interface, allowing client applications to browse tags, subscribe to updates, and perform read/write operations with quality indicators and timestamps. By using a widely adopted OPC DA interface, it streamlines integration, reduces the need for custom drivers, and enhances interoperability across multi-vendor environments.

Key features:

• OPC Data Access (DA) interface for real-time connectivity
• Read/write operations, tag browsing, and configurable subscriptions
• Data quality flags and time-stamping
• Support for common industrial data types (Boolean, integer, float, string, arrays)
• Flexible namespace mapping to ISaGRAF variables, tasks, and I/O
• Diagnostics and logging to aid commissioning and troubleshooting
• Access control using Windows security and DCOM settings
• Designed for Microsoft Windows environments

Typical uses:

• Connecting ISaGRAF-based PLCs and RTUs to SCADA/HMI platforms
• Publishing plant-floor data to historians and reporting tools
• Commissioning and testing ISaGRAF applications with third-party OPC clients
• Integrating mixed-vendor control systems via a common interface

System considerations:

• Requires network access to the ISaGRAF runtime or target controllers
• DCOM configuration and firewall rules may be needed for remote clients
• Performance depends on update rates, tag count, and network conditions
