One Click OPC UA

Tags can be automatically set up using the One Click OPC UA feature, which browses OPC UA servers automatically and creates tags based on the nodes defined in the OPC UA server. You can then delete tags from the configuration that are unnecessary.

Note: You will need to be running Open Automation Software Version 12.0.0.9 or greater to support the One Click OPC UA feature. You can download the latest version from our Open Automation Software Download page.
