Shared Variable through the internet

[_Bryan]

  We have a remote site that is running LabView to record some data.  Currently we can log on to the computer using VNC (remote control software), we use a static IP address with a port number that connects to a gateway that uses port forwarding to get to the machine of our choice.  Doing that we have control of the whole computer, but the transfer of anything is slow and the screen refreshes about every 5 seconds or so using a low (64) color setting, using full color is almost painful.

  So the latest idea is to be able to send data from the remote system and display it or save it on a local system.  The idea would be that only data is being sent which should be faster since we would not have to worry about transfering graphics and other stuff.

  I have been playing with shared variables all day and searching the forums.  From what I have read it sounds possible, but I have not been able to do it yet.  I am wondering if there is a problem with the port forwarding.  I have tried tools > shared variables > register computer, but it has not helped.  Is there any good detailed instructions on how to use shared variables over the internet?  I do not have any VI's to share because I have been using the help vi's.

Bryan,

Let me know if I understand your problem.  You are trying to remote into a computer using VNC over some sort of network to gain access of a VI that is running on that machine.

The problem is that the computer you are looking at is updating slowly.  Is the VI collecting the data returning the correct values at the correct rates?

Have you thought about using Remote Front Panels?  If you are just trying to access another VI on a computer on the network, I would try this.  You may also want to check out the Web Services, which is new for 8.6.

Have a great day,

Currently we VNC into the remote machine, which is slow over the internet (limited upstream bandwidth).  The machine is working as it should at the remote location.  I want to run a VI that will collect only data from the remote machine so that I can either plot or store it locally. 

  I figured remote panels would have the same problem as the VNC because of the limited bandwidth.  So I only want to send data and no graphics over the connection.  The remote computer is hooked up to a satellite dish for it's internet connection.  I have 8.6 for the remote machine, I just have not installed it yet, so I can look into the Web Services.
