Pass parameter to LabView-VI in batch mode

[geraldW]

Hello,

I am executing LabView-VIs in batch mode, that means my batch-file calls the VI and the VI immediately executes, since its VI-properties are set in this way.
However, my requirement is that I pass a parameter value to the VIs (a string).
How can I do this in batch mode?

Hi geraldW,

look for search topic "command line parameter" here in the forum - you will find many threads on this topic with quite good explanations on hwo to do it!
There are examples provided by NI too!

Hello,

thanks for your help.
The parameter passing works, I took the VI CommandLine and modified it.
However, you have to close LabView each time you want to pass new parameters to the VI. I would like to run this VI in a sequence and each time pass new parameters.
Thereby it is time-consuming to restart LabView each time. Is there a way around this?

Hi Gerald,

make an executable from your vi! This should be the preferred way when you need to call your program from within a batch file.
Instead of loading LabView development environment this only loads the runtime engine and will speed up loading this way...

Hi,

I am using LabView Full Development System, therefore I have no Application Builder. I cannot build an exe without Application Builder?
I would prefer not to buy the Application Builder. Isn't there a way for passing parameters in a reasonable way without using executables?

Hi Gerald,

of course there are other ways.
One way could be to use a text file to pass parameters like this:
*** snipppet of batch file
echo parameter1 > c:parameters.txt
wait 100
echo parameter2 > c:parameters.txt
*** snippet end

Your vi is running all the time and checks the parameter.txt-file for new data (file palette-> file/directory info). When new data is passed, the file is read and parsed...
