Creating an OPC-UA Tag

After creating a tag and selecting an OPC-UA device, you will be expected to fill out the following fields:

Device Browser

The device browser allows you to view a list of OPC-UA nodes and identifiers from the server. Click the browse button to show the OPC-UA Tag Browser. Nodes indicated with a folder will contain other nodes within. Nodes indicated with a tag icon are able to be read by Koios. Click on a tag to populate the form automatically.

When using a device set, use the dropdown to select the server you want to browse.

Namespace

We all float down here

The prediction from a Koios AI model is always output as floating point and then converted to the data type defined. We currently only support converting to floats, integers, booleans, and strings.
