Kepware Client Ace

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 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.

• 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.

The Server Browser control provides functionality to browse OPC Data Access servers on local and remote machines. The Server URL is returned in an event to be used in the application for establishing connections and data acquisition.

The Item Browser control provides functionality to browse tags/items in an OPC Data Access server on local or remote machines. Items/tags are selected and their information is returned to the application. The selections are used to request updated data from the server.

The Channel Settings control provides functionality to view and make certain changes to the properties of a channel and devices within an OPC server provided by Kepware. The ability to write to system-level tags must be enabled in the server.

The Server State control provides functionality to view the properties of a Kepware OPC server project. The properties include the number of clients connected to the server, the total number of tags added by the clients, and the total number of tags that are actively being polled.
