This job comprises adding OPC DA and UA access to an existing WPF application. The OPC library preferred right now is Advosol, but other libraries may be considered if the developer has previous experience with a library. If needed, the core DA functions requested can be created in a separate application.
The application will have to support several instances of long running OPC actions including flat browsing, tree browsing, reading and writing large amounts of data items.
The application will involve some modifications to an existing WPF GUI including modifying treeview and datagrid controls.
Hand drawn application wireframes and specifications will be provided.
