Remote computer vi

[Tak Chan]

Hi everyone,

I have a few questions regarding embedding a VI to a compact field point controller and starting it remotely, hope someone can help me with.

I have a cFP-2015 controller, and I would like to embed a VI to this controller and remotely start or stop this VI from a host computer running windows xp. I managed to embed the executable file to my controller and configured it to launch the application at boot-up. It seems to be working as it should but I have no control in stopping the program once it starts.

Then, I came across the "Remote_Computer.vi" from NI which seems to allow me to start and stop my VI remotely. However, I couldn't quite totally get this to work out.

It seems to me that all I need to do is to upload my VI (say FP2015.vi, not the exe file mentioned above) to my 2015 controller and include the corresponding path in the "Remote_Computer.vi" and run the "Remote_Computer.vi." However, after I upload my VI, re-boot the controller, and run the "Remote_Computer.vi," this VI fails to start my remote VI in the controller. I wonder if it is because my controller has not load this VI in memory or it is because I have an incorrect path name for the VI. The path I used in the "Remote_Computer.vi" is like this

C:\NI-RT\STARTUP\FP2015.VI

Is this not correct? I tried to use a wrong path but I usually get an error message with it, so I am not sure what is wrong.

Also, another thing that I don't understand is that when I embedded the exe file to the controller and re-boot my controller, my controller run my VI as it should (at this point, my FP2015.vi is still present in my controller). Now, when I run the "Remote_Computer.vi," I CAN remotely start and stop my FP2015 VI. Why is that?

Many thanks in advance!!

Tak
