Problems running remote 6.0 VIs from 6.1?

[Ian Renton]

I am attempting to run a number of VIs on remote machines from one machine (the front panel machine), using Open Application Reference and Open VI Reference, then telling it to run the referenced VI. This seems to work for VIs on three machines that are running LabVIEW 6.1 (as is the front panel computer), but when I attempt to run a VI in this way on a machine using 6i, it doesn't start running. I'm loading the VI first using Telnet, which works, but the VI just doesn't run when it is told to.

Any thoughts? In the end we may upgrade the 6i machine to 6.1, but being able to run a VI remotely on a 6i machine would be useful until then.

You'll need to use the same version of LabVIEW.

Do you get any errors coming from the error cluster?

Another option that _might_ work (although it isn't designed to work cross versions) is to use DCOM via activex rather that using vi server.

Thanks for the help.

Open Application Reference and Open VI Reference both seem to work, but the Invoke Node produces an Error 1 (An input parameter is invalid). I assume that's implying that the Invoke Node in LV 6.1 can't handle something about the data that Open VI Reference is sending out.

It seems upgrading to 6.1 might be the easiest solution anyway...
