Issue Details

I am trying to publish data on a Web GUI using LabVIEW HTTP Client VIs. When I run this code on my host computer is works fine. However, when I run this code on a cRIO controller, I get the following error:

 

Error 7 occurred at Call Library Function Node in LabVIEWHTTPClient.lvlib:OpenHandle.vi:6450001->Publish_To_PTC.vi

 

Possible reason(s):

 

LabVIEW: (hex 0x7) File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.
 

Solution

Install the HTTP Client with SSL Support on your real-time controller to use LabVIEW HTTP Client VIs.
