Updated Dec 11, 2025

Environment

Software

  • SystemLink Cloud
  • LabVIEW
  • SystemLink

To send and receive data from the client to SystemLink Cloud, you need to use the functions described in this API reference . Here we will see how to use the SystemLink API available in LabVIEW to create, write, and delete tags from LabVIEW running on the client to SystemLink Cloud.

  1. Log in to SystemLink Cloud . Click here for information on how to activate your SystemLink Cloud account. When accessing and data communication from a client PC to System Link Cloud using API, it is necessary to issue API Keys in the security item.



  2. From the API keys screen, select NEW API KEY, this will create a new key.



  3. When the API key is issued as shown below, click Copy Key and save this API key in another location. 



  4. Next, open the menu button on the upper left and open the Tags of the Data item. Here you can check, create, update and delete tags registered in SystemLink Cloud. This time, we will use the LabVIEW sample program to create a tag on SystemLink Cloud.
  5. Open LabVIEW and access the NI Sample Finder(Help>> Find Example) . For SystemLink related samples program to show up in the sample finder,  SystemLink API should be installed.
  6. Insert "Tag" as keyword to filter out Tag related sample programs, and open the "Simple Tag Manager.lvproj". 



  7. From the Simple Tag Manager.lvproj, open the Simple Tag Manager Client.vi,  and enter the API key you created earlier in System Link Cloud.
  8. To create a tag, navigate to the "Create Tag" tab, insert a Tag name (Tag Path), value and run the program. This will create a Tag with the specified name and value in SystemLink Cloud's Tag Screen as displayed in the below picture.  Tag Path can only use alphanumeric characters. 



    You can use the "Write Tag" tab and "Delete Tag" tab to respectively write or delete tag in Systemlink Cloud.
