  • LabVIEW Remote Panel Server
  • LabVIEW Application Builder Module

Issue Details

I am having multiple LabVIEW executables on my machine. Is it possible for me to access these executables simultaneously using Remote Panels through a web browser in different computer?

Solution

This can be done. There are two factors to consider. The first is Remote Panel Licensing and the second is the Web Server.
  • Remote Panel Licensing: You must have a license for each instance of your executables which will be opened. For instance, if you are hosting three executables, and they will each be simultaneously referenced by three computers, you will need multiple connection licenses. When creating your LabVIEW application, remember to include Remote Panel License Support. This can be set in the Advanced options in the Installer Settings tab of the Application Builder. Note: This applies to LabVIEW versions older than 2011. Versions of LabVIEW 2011 and later do not require any licenses for remote front panels.
 
  • Web Server: Each executable must be running its own separate Web Server. This is accomplished by serving each executable through a different port number. Within the Web Server: Configuration options for your executable, you can set which port number serves each executable. To access the executables, use the following http address format in your browser's window: http://[server ip address]:[port number]/[application name].htm
 

Additional Information

Sometimes, you will encounter an error when starting to use the remote front panel from the web browser such as blocked plugin and Microsoft Silverlight issue. Please kindly refer to the knowledge base: Remote Front Panels, NI Network Browser, or WIF Don't Work in Browser .
