What runtime files are required to view a LabVIEW VI "web page"

[Chuck Schumann]

I'm writing a Windows LV application that will serve up the front panels as web pages. I need to put the LV PDA runtime files on the PDA so that the VI will display. What files need to be loaded onto the PDA? Where do they need to be placed?

Hi Chuck!

If you are just wanting to be able to monitor the front panel from your PDA, you will be able to do so pretty easily and without any installations on your PDA. To do so, in the Web Publishing Tool, set the front panel to "monitor" or "snapshot" (not "embedded"). Then when you view it on the PDA it will be just like a normal webpage.

However, you will not be able to control the front panel (by setting it to "embedded" in the Web Publishing Tool) from your PDA. This requires the LabVIEW Run-time Engine, which PDA does not support because of the ActiveX controls. To be able to control (communicate with) your VI, you will need to implement to separate VIs. The actual VI running on the host PC, and one for the PDA. The two VIs can communicate via TCP communication, which will enable you to read and write values between the two VIs.

For more information, please read this KnowledgeBase:

This is very unfortunate. When I was quoting and specifying this project I read somewhere, and I thought it was on the NI site, that the only think only thing needed to control a VI with in the web browser on the PDA was the runtime. Which make a lot of sense. Now that my project has been bid and accepted I learn that the code development needs to be a PDA target, which is much more tedious to say the least.

Are there any examples of a PC and a PDA exchanging messages using TCP?

Hi Chuck,

I'm sorry to hear that you were previously misinformed on this issue. If you were presented this information somewhere on NI.com, please notify me of the location. Furthermore, hopefully these links will be able to assist you in your development!
