Multiple Execution of VIs in TestStand

[jensw@my-deja.com]

Hi everybody,
I'm trying to run multiple VIs with TestStand. Right now I'm using the
ActiveX command : Engine.NewExecution to start multiple Sequences which
contain 1 VI. To communicate between these Sequences, I have to use
StationGlobals. Is there a possibility to use one Sequence File with
all my Subsequences and LabVIEW steps, that could be called once and
then executes the steps at the same time, so that I don't have to use
StationGlobals and different Files.

Thanx Jens

Hi Jens,

You will need to use station globals or a file to communicate. Each
execution makes its own runtime copy of FileGlobals and these runtime
copies are not shared between the different executions.

I'm not sure if you are attemption to run VIs of the same name at the
same time. If so, you can set those VIs to be Reentrant. But you
will need to upgrade to TestStand 1.0.1. You can upgrade at
www.natinst.com/advisor. It is a free upgrade.

Thanks,

Thank you very much,
you are right, I want to execute the same vi twice with TestStand (I'm
already using StationGlobals for the communication). I will upgrade
then the next days.

Best Regards
Jens

Jens,

If you are calling VIs of the same name and if those VIs display their
front panel, those VIs cannot be set to reentrant. However, we made a
step type that works around this issue. You can download an example
named, "Step Type that Executes LabVIEW Code Modules in Parallel" from
the NI examples database at:
http://digital.natinst.com/explprog.nsf/web%2Fswgrp?
OpenView&Start=1&Count=500&Expand=7.1#7.1
This example also requires TS 1.0.1. If your VIs don't display their
front panels, then you should make your VIs reentrant as I mentioned in
a previous message.

You can always get to the examples DB from www.natinst.com/support
