How do i run two VI's on two computers over a ethernet link and control from both ot them at the same time, just like PcAnywhere connection.

[spradecom]

I Have two computers, one of them has DAQ cards and some other communication cards in it, this pc is in the wiring closet, i have another PC(PC2) which is situated about 100mtrs from the main pc and they are linked with a CAT5E 100mbps switched ethernet.

I want to control the VI's running on the main PC from PC2, I also want to control to happen from the main pc also. I'm running about
100 -200 different VI's (25 of them are in the mem at all the times) on the Main PC which are doing a lot of things such as aquisition, control , monitring and logging of a Paper Manuf. Plant.

what will be the best and eas
iest method to accomplish the task

Check out VNC. It sends a local screen image to a remote computer,
much like X does for Unix. Viewers and Servers are available in a lot
of formats (Windows, Linux, other Unixes, (Mac?), Java, even
Palm). And it has a GPL license.

thanks, i've been using VNC for the last 3years, but this is not the solution that i'm looking for.
what i'm looking for is that the two machines should be working independently, and the data should be updated between them, but the actual field control should take place from the main pc and not the remote pc the remote pc should be able to send commands which will show up on the main pc and what ever commands are seen on the main pc should be seen on the remote pc. it is just like using datasockets publish and subscribe feature and doing a enable multiple writers on the same.(This I just found out there is not documentation on data sockets , Labview 6i documentation sucks, its horrible, non existant. I have LV 5 and it came with soooooo much documentation(printed
) that you could do weight training with it.

VNC is good, but Radmin 2.0 ist better.
Remote Administrator v2.0 is much faster than VNC.

You can use either datasocket: easiest way or TCP/IP: more complex but more performant.
I do agree does not support these features as it should.
Alternatively I'd suggest a book: Internet Applications in LabVIEW which is absolutely a must for all communications tasks.
You can find it on Amazon.
