OPC UA .NET Client SDK + OPC Classic

How to use

The OPC UA .NET Client SDK enables the development of OPC UA client applications according to OPC UA v1.03 and higher. The support of OPC Classic enables communication with OPC Classic servers via OPC DA, OPC HDA and OPC AE. To establish a client connection, the server address including the transport protocol scheme (see below) is sufficient. To connect to an OPC Classic server, the ProgId and ClassId are also required. No membership in the OPC Foundation and no licence other than that for Traeger's SDK is required for development!

An OPC UA client can be realised with a few lines of code. The OPC UA Client shown below reads the value of a data node with the NodeId "ns=2;s=Hello" and outputs it on the command line.

Access to the respective data nodes works with the usual NodeId syntax (even after optional resolution via the Browse and Translate services). Any .NET language such as C#, VB.NET and C++/CLI can be used for programming. The interfaces themselves only differ in terms of the programming language used. For the connection to OPC Classic Server, the SDK must be used under Windows.

Undecided?

Only OPC UA servers need to be addressed? The OPC UA SDK is also available without OPC Classic: OPC UA .NET Client SDK

The data of the OPC (UA) server should be retrievable via REST API, stored in a database, forwarded to other devices or simply visualised? Take a look at our OPC UA Middleware: Codabix Industrial Edge

Licensing

Once purchased, a licence is valid indefinitely (= unlimited licence lifetime) and allows the development of any number of products as well as their unlimited distribution without further licence costs (= royalty-free). Included are 12 months Top Level Support by our developers as well as updates including new functions.

Shortly before the support expires, it is possible to extend it for at least another 12 months for 15% of the current list price. Updates and new functions can only be obtained with valid support. Support requests can still be submitted, but will be processed on a priority basis depending on their scope. Up to one month before the expiry of active support, we will notify you of the possibility of support renewal. Support renewal is possible at any time in the first year after expiry of support for 30%, in the second year for 60% and in the third year for 80% of the current list price. From the fourth year onwards, a new licence must be purchased for the support renewal.

Branch License

A Branch License applies to all developers who use the product for software development exclusively at the location (= a postal address at which development takes place) according to the licence agreement.

Single Developer License

A Single Developer Licence applies to a single developer who, according to the licence agreement, is the only one (= full contact details of the developer and employer) to use the product for software development.
