Export OPC UA Nodes as a CSV File

Requirements:

• Management Console Downloaded & Installed
• Logged in to the Management Console
• A UMH instance is installed
• An uninitialized connection is added

When should I use it?

At initializing connections or editing data sources of OPC UA, you need to add/edit nodes for them. If you want to download the current nodes as .csv and edit them, this tutorial helps you.

What can I do with it?

This feature allows you to download the already configured OPC UA nodes, which belong to the selected uninitialized connection or datasource, as .csv file.

How can I use it?

1. First, open the device overview page and click on the datasource tab. You shall be able to see the overview of datasources now. Click a three-dot icon of a connection which you want to initialize, then click on the Initialize button.

   

   

   

   

2. The next page displays status of the connection and allows you to configure some security settings (coming soon). Make sure that the Connection Health status is Good and click on the CONTINUE.

   

   

3. You will be asked to choose a method for adding or editing node subscriptions. Click on the ADD OPC UA NODES VIA .CSV FILE.

   

   

4. Now, you shall be able to see an example .csv layout. Click on DOWNLOAD CSV to start the process.

   

   

5. Next, choose your directory and enter your file name. Clicking on save stores csv data in the specified file.

   

   

The content of .csv file downloaded by this tutorial is empty because the connection is not initialized, i.e., subscribed nodes are not configured.
