Write down the Project Name, and then click [ OK ]. Username:. Note that not all interfaces and methods are implemented for PI MDB. The tags are defined by a path property, which should point to a node ID of a variable in the OPC-UA tree (for more information on determining node ID’s, see the Browsing the OPC-UA Server section). Steps 5-7 are similar to those from the previous example "Writing a lot of OPC tags". For any tags that you add to the Tags property, the node outputs data in an XML format. Examples VB Console, C# Console. Additionally, because no OPC client is complete without the capability to perform OPC Tag Browsing, the complex OPC client example implements a complete Tag Browsing interface with filtering. Normally they are located on 2 different computers in a Network. Reading tags and Node IDs from your OPC UA Server and moving that data to Excel can be difficult without proper documentation for the OPC UA Server. OPC UA Server.
