Does OPCTrend.NET support OPC HDA?
No, OPCTrend.NET is a client/server architecture that does not require DCOM and the communications uses the built in networking to the .NET Framework. This makes it possible for trend clients to view real-time data and historical data with OPCDatabase.NET from anywhere in the world over the Internet.
The OAS Service can bring in data values from Data Access OPC Servers, Data Access OPC Clients, databases like SQL Server, Oracle, Access, and mySQL, Microsoft Excel, and .NET applications (web, WinForm, WCF, WPF, and Windows Services).
The values can then be cached for unlimited trend clients and logged to databases with OPCDatabase.NET. Trend clients can be running on both Windows Operating systems and non Windows Operating systems like smart phones and the iPads.
