OPC Watch
Download: https://docs.traeger.de/en/software/sdk/opc-ua/net#download
Usage: Browse, read, write, subscribe nodes or generate code for user defined types from server or nodeset.

Features:
• DA: Data Access
• HDA: Historical Data Access
• AE: Alarms & Events + Conditions
• IO: FileAccess
• API: Methods and Enumerations
• OPC Classic Support
• Others:
 • Units of Measurements
 • Complex/Structured Data Types

Characteristics:
• Simple and fast Client & Server Development
• Minimum number of lines of code
• Uses OPC Foundation Stack v1.03.351.0
• Significantly reduced lines of code compared to OPC Foundation Stack

Framework Features:
• Data Types using Name-Value pairs, .NET dynamic and user defined types
• Linq to Objects support to browse nodes
• Simplified automatic certificate management
• Advanced node identifier formats like compound, URI or Foundation
• Database Cursor like historical data access
• Event driven programming model for certificates and subscriptions

Tested with:
• SIMATIC S7-1500, SIMOTION, SINUMERIC, ...
• and many more other vendors

Works on:
• Windows
• Ubuntu
• Debian
• macOS

Optimized for:
• SIMATIC S7-1500 / S7-1200
• SIMOTION
• SINUMERIC
• all OPC UA Servers from Siemens and other providers

The OPC UA .NET SDK comes with an evaluation license which can be used unlimited for each application run for 30 minutes. If this restriction limits your evaluation options, you can request another evaluation license from us for free. Just ask our support (via support@traeger.de) or let us consult you directly and clarify open questions with our developers!
