Server Development SDK for OPC DA/AE

The OPC DA/AE Server SDK offers a fast and easy access to the OPC Data Access (DA) and OPC Alarms&Events (AE) technology. Develop OPC DA 2.05a, 3.00 00 and OPC AE 1.00, 1.10 compliant Servers with any compiler capable of either

  • generating a Windows DLL (OPC DA/AE Server SDK DLL). This results in a generic server executable plus a Windows DLL.
  • generating a .NET 4.8 assembly (OPC DA/AE Server SDK .NET). This results in a generic server executable plus a .NET 4.8 assembly.
  • generating one server executable without the use of any DLLs (Source code version required).

The developer can concentrate on his application and servers can be developed fast and easily without the need to spend a lot of time learning how to implement the OPC specifications. The server API is easy to use and many OPC specific functions, e.g. creating a group or adding an item to a group are handled by the framework. Even the complex asynchronous read/write handling is handled by the framework.

The “Framework” includes all OPC DA 2.05a, 3.00 and OPC AE 1.00, 1.10 handling and ensures the OPC compliance. It is implemented as a generic C++ based executable.

The “Server API” defines easy to use interface functions required for developing OPC DA/AE compliant servers. The OPC server is supplied as an EXE file with full C++ source code and the application adaptation part in 1 file. This imposes some limitations on the adaptation possibilities but makes the adaptation much easier and quicker. By using this API OPC servers can be easily implemented by adapting just a few functions, e.g. there are only 5 functions that have to be implemented for an OPC DA Server. The functions handle the configuration of the server and the read/write functionality of items.

The OPC DA/AE Server SDK offers unique features for performance and functionality improvements of the developed OPC Server like Event Driven Mode for Device Access; Dynamic address space with items added when they are first accessed by a client and removed when they are no longer in use; Item browsing can be implemented to browse the cache or the device/database.
