Welcome to SystemLink Cloud!
To connect your web app to SystemLink Cloud from LabVIEW NXG 3.0 Web Module, you need a server url and an API key. The API key authenticates the web application running on your local machine for SystemLink Cloud – much like your ni.com credentials authenticate your identity.
- Go to Security.
- Click + New API key button to create an API key.
- Click Copy key to save the API key. Note: You will only see the API key once, so it’s extremely important you keep it somewhere safe.
- Open LabVIEW NXG and create a WebVI. Tip: Use the Web Application Project template to easily create a WebVI.
- Go to the diagram and navigate to Data Communications»SystemLink»Configuration.
- Select the Open Configuration node and drag it to the diagram.
- In the Function configuration dialog box of the Open Configuration node, select API Key. Changing the configuration of this node enables you to establish a connection with SystemLink Cloud.
