Scilab Script in Labview

I am trying to invoke a Scilab (v4.1.2) script in an empty Labview (v8.5.1) VI, and am continually receiving an error simply telling me that an error occurred while running the script. The script works in scilab alone. I've commented out the 'd' input in the script to try and have labview control it just as my first attempt at an interface between these two programs.
Can anyone see where I am going wrong, or possibly how I could figure errors like this out on my own? It just doesn't point me in any direction to find the error, so I'm stuck.
Thanks

Hello,
I see some problems when running the script as well. It seems there are some slight problems communicating with the Scilab software.
First, when looking at the text in the Scilab script node, I see an extra character before the new line. Upon closer investigation, the script contains both a carriage return and a line feed at the end of every line. This currently causes a problem with the Scilab software. I was able to eliminate the extra character (the CR) by loading the script from disk in a text editor and copying and pasting it into the script node.
Second, getcwd may not return what you expect. It is not the directory in which the VI resides (unless you happened to put the VI in Scilab's default working directory). You can find out what it returns by simply calling that function and then creating a string output variable on the script node. Another method to specify the location of your data file is to pass in a string that is the current VI's location on disk. You can find this using the Programming >> File I/O >> File Constants >> Current VI's Path primitive. Simply use the Strip Path primitive to get the directory name. Wire that into the script node as a string input and then append the filename like you currently do.
Third, comments in the script seem to cause some problems. The script node doesn't actually return an error, but most of the script simply doesn't execute. Try removing all your comments from the script.
Last, the Scilab-LabVIEW Gateway currently does not support plotting from the Scilab software, so your plot commands will not work.

Problem creating inputs, outputs and text in Scilab Script Block

I have recently installed the Labview to Scilab Gateway. I am running Labview 11.0 and Scilab 5.3.3. The example files run properly, However, when I try to define any inputs, or outputs, there is no option to add the ports. The block also ignores any text I type in it or copy to it. I have been trying this on a blank vi.
Solved!

Hi Ronny,
I have a few more questions to help us debug this issue. You said you tried the same right-click procedure to create inputs and outputs on a normal script block and it worked as expected. What specifically do you mean by a "normal script block"?
How did you drop the empty Scilab script node on a blank VI? Did you drop it from a palette or paste it from another VI?
Can you post an image of your Help >> About LabVIEW screen (feel free to obscure your name, company, and license number)? If not, can you provide the LabVIEW version number specified from that screen? There have been a few patches to LabVIEW 2011 and it will help us to reproduce the issue if we know exactly which version you have. Also on that screen, do you have LabVIEW Base, Full, or Professional (or maybe an Evaluation or Student edition)? The Scilab script node will not work in LabVIEW Base and the right-click menu will look as you describe. You can verify your LabVIEW activation in the NI License Manager.
Do you have any other versions of LabVIEW installed on your computer? Is LabVIEW 2011 the most recent LabVIEW you installed? How about previous versions of Scilab? Do any previous versions remain or did you remove a previous version of Scilab AFTER installing Scilab 5.3.3?

Same code gives different results in Matlab Script in Labview and Matlab

I am implemeting a Matlab code into a LabVIEW application using Matlab script. When I import the exactly same code to the Matlab Script in LabVIEW it gives a different result than it is in Matlab. This code is a simulation code including first kind bessel functions. Using LabVIEW 7.1 and Matlab R14 service pack 3.

Labview 8.5
Matlab R2009b
Attached are the graphs produced by matlab script in labview and in matlab.
The minimum of graph produced by matlab code is below 1 and that in labview is above 1.
Thanks a lot for your reply.
Sorry, I haven't quantified the "sometimes" yet.

Calling a vi in scilab script

Hello!
What I'm trying to do here is the following: I am developping a VI that uses a certain algorithm to function. I put the algorithm into a Scilab script structure, no problem here I already did that.
The problem is, during the execution of the script at many points I need to get additional data through a sub-VI. I want to avoid a structure that looks like Script=>sub-VI=>Script=>subVI=>etc...so my question is: how can I call a sub-VI from inside the Scilab script?
Thank you very much!

Hello, thanks for the quick answer.
I do not have a screen capture at hand, besides my VI a a bit too messy at the moment, but hopefully it can be explained quite clearly.
Basically, I am implementing a Nelder-Meads simplex method, where the input of the script is the coordinates of 3 points, and from it the coordinates of one or two other points are calculated. Problem is, from here the algorithm needs to go measure those new points physically, using another sub-VI. After which I need to input those measurements into another script so I can compare all the points and choose which ones are better.
Actually I decided to code it like I described, alternating scripts and sub-VIs (I kinda had a schedule to follow ), but I thought it would still be interesting to know if it is actually possible to do it with one big script.
During my search I found some interesting leads using matlab, namely using ActiveX (there) but I couldn't find corresponding commands in Scilab.
Any ideas about that? or any other ways to do it?
thanks!

Scripting in LabVIEW

Hi, could you please let me know what is the easiest scripting method that can be used in LabVIEW, we have engineers that know nothing about LabVIEW, they want an scripting language to do simple things like assignments , for loop, while loop and basic math functions such Mean . Is math script ( Matlab) the best choice?
The problem I have with Math Script is , I think it is good for complicated mathematics but it can't be used as a command script for LabVIEW ?
For example if I have this line in that scripting window
vpp= 10
then I would like to pass that value to a VI, if I don't have this line then there is no need to have that VI
Is there any LabVIEW scripting language that can be good for this purpose?

Thanks jcarmody and Yamaeda for your suggestions
Before working on your idea about using Paython I would like to show you one example and if you think the toolbox can handle that I will continue
This is one of the m files ( matlab ) provided by them:
As you can see below they can call functions , use basic math functions and use basic commands such as if , for , while?
They would like to have an environment like this but when for example they call a function I don't want to run a Matlab or Paython code. I want to run a SubVI which is specified for that command and then we goto to the second line and continue. SO everything should be implemented in LabVIEW but I want to give them this capability to write scripts (since they don't know LabVIEW) but everything should be execute in LabVIEW. Can the Paython toolbox give me this capability?
If not do you have any suggestion

Using Matlab script in Labview

Hello,
I am trying to use matlab script in labview to post process the sampled signals from DAQ(attached is the vi I tried)
After every 10 seconds I want to the send the sampled voltage data to matlab scritp block which does 1) detection of peaks using peakdetection function and plots the obtained peaks on the sampled signal 2) calculates standard of 10 secs data and plots on chart.
But I am confused of 1) how to call the peakdetection function inside the matlabscript block
2) How to send the 10secs data of voltage and time values to the matlab script block
3) How to plot the signal and detected peaks on the same plot (which can be done in matlab using holdon as shown in the atached vi).
Can someone suggest for implementing these .
Thanks.

Thanks GabeG,
Now, Labview&Matlab_TestNoAq.vi is woking Good and for the second one Labview&Matlab_TestAq.vi it is showing error as shown in the attached image when these ines of code are present in the matlab scrtip
subplot(2,1,1),plot(maxtab(:,1),maxtab(:,2),'*r');
SDN=std(maxtab(:,1));
and SDN output of the Matlab script
but when I removed these it is working fine(but not showing the detected peaks).
Can you suggest me a solution for the above and also can I know the best method to add one more channel that samples another device signal which has to be processed in this same way(Signals sampled from 2 devices have to be porcessed in this same way).
Thanks.

Controlling dialog boxes in a DIAdem script from LabVIEW

I have a DIAdem script that prompts the user for the data file it will process. The datafile was created from a labview test routine. I can now run the script from LabVIEW using the "DIAdem Run Script.VI", but in the interest of automation, I would like to have LabVIEW place the filename in this dialog. I would like to keep the dialog in the script, since sometimes we run this script manually. (without LabVIEW)
Bill W.

Bill,
Which dialog are you using to prompt for the file name? It
appears that you cannot send any information to the script through the
Run Script.vi. However, you can call automation commands using
the "DIAdem Run Automation Command.vi". If you want to pass data
to the script, then you can set a Global Variable, or a DIAdem Script
Variable. As an example, you could use the global variable, T1,
and send "T1 := 'myfile'". When the script is executed, that
variable will be accessible within the script and it will be set to
"myfile". You could also set the FileDlgName variable to your
file name. Then it may be possible to send those variables to
your dialog so that they are automatically populated.
Good Luck!

I want to call the Python script from LabVIEW.
I tried with using at the command line but i am unable to run that script file..
i have gone through LabPython but i am unable to call the scripts from there also..

How to call QTP scripts using labview

Whether any API or dll calls can be used to access the QTP scripts?

Hi,
I think there we can execute QTP script from command line. Please look for that option. If that option is there, we can use the same command in LabVIEW cmd line interface to execute the QTP script. Curretly I am using TestPartner which is more similar to QTP.I am executing my TestPartner script through LabVIEW using command line interface.

Halt script with labview

let's say I execute a script using the "diadem run script.vi" due to user request. Later, the user wants to cancel because it was taking longer than expected.
How do i halt the script using labview tools?
jim
Solved!
Go to Solution.

Hi Jim,
This is possible, but not in the way I believe you are hoping. I know of no way to halt a VBScript running in DIAdem from the "outside". If you were staring at DIAdem you could hit the <ESC> key, but any subsequent request from LabVIEW will go onto DIAdem's "Script Stack" and will not be executed until the first VBScript is done naturally.
Of course you have to run all your LabVIEW calls to DAdem asynchronously, or nothing helps.
So what you can do is set up each VBScript that you think you might want to abort to periodically poll a DIAdem global variable, say "B9", and terminate from inside the VBScript if B9=TRUE. The command interface from LabVIEW to DIAdem (ToCommand) goes onto the DIAdem Script Stack, but the variable interface from LabVIEW to DIAdem (ToDataSheet) does not. So you can "poke" variable B9 from LabVIEW while the first VBScript is running and affect it's behavior, but only if and when that VBScript uses that (B9) variable you poked.
Of course none of this helps if your VBScript is busy waiting for a single VBScript command to execute, and it only helps if your VBScript is running multiple activities, between which it can poll the (B9) variable.
Hope that helps,
