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. The Management Console provides multiple methods to manage nodes. This feature allows you to import nodes via CSV file. You can first modify the CSV file in your confortable way and update OPC UA nodes.

What can I do with it?

This feature helps you import nodes via CSV file. During the process, it runs CSV-validation based on the OPC UA specification and the Management Console’s data structure. If you want to edit nodes belonging to an already deployed data source, check this page to export a CSV file
