ClientAce - OPC .NET Toolkit
  DA Junction Control

The DA Junction control is a customized .NET control that enables Visual Basic .NET and C# programmers to easily develop OPC client applications that access any OPC UA, OPC DA, and XML DA servers. No detailed knowledge of OPC Data Access interfaces is required. The DA Junction will perform the connection handling procedure between your custom client application and the OPC server, as well as monitor and reconnect when necessary.

ClientAce DA Junction

ClientAce DA Junction Features:
  • The component completely covers the connection handling procedure for one or multiple OPC servers.
  • Conversion of OPC data from different OPC Data Access interfaces into .NET data types.

PC Hardware Requirements

Refer to Microsoft's .NET Framework hardware requirements for the version that will be used in the Visual Studio project:
  • 100 MB available disk space
  • Microsoft Visual Studio Requirements
When deploying the custom client applications created using ClientAce, the .NET Framework requirements depend on the version of Visual Studio that was used for development. For more information, refer to the appropriate section in Deploying Your Client Application.

PC Software Requirements

The following requirements must be met in order for the application to operate as designed:
  • Microsoft Windows operating system requirements are the same for both ClientAce and the Microsoft Visual Studio development environment that is used to develop ClientAce applications. If the operating system's requirements for the version of Visual Studio being used does not list the operating system intended for use, then ClientAce is not supported for use on that operating system.
  • UAC on Windows Vista and Windows 7
  • To ensure that all components function correctly in the design environment, turn UAC off on machines being used to develop applications with ClientAce.
  • UAC limits access to folders and files in the design environment, which will affect some objects in the design environment. UAC does not affect these objects in the Runtime environment.
Runtime Requirements

Visual Studio 2010 C++ Runtime Redistributables
  • Part of the low-level OPC layer for ClientAce is written using C++ in Visual Studio 2010. As such, ClientAce has a dependency on the redistributables for that version. It is important that these files be present when deploying a custom client application created using ClientAce. The installer for the redistributables can be found in the ClientAce Install folder.

OPC Foundation Core Redistributables
  • OPC DA client/server connectivity requires the OPC Foundation Core Redistributables, which are usually installed when an OPC client or server is installed to an operating system. When deploying a custom client application created using ClientAce to a PC that has never had an OPC client or server installed, the components must be installed for it to work. The installer for the OPC Foundation Core Redistributables can be found in the ClientAce Install folder.
