Send SMS Text using Gmail STMP and AT&T SMS Gateway

I'm trying to send a text message to my mobile phone using my GMAIL STMP server and my carrier (AT&T)'s SMS Gateway. When I run this VI, I get:

 

Error 363504 occurred at LabVIEWSMTPClient.lvlib:Send.vi:2280001
Possible reason(s):
LabVIEW:  Invalid username or password combination.

Complete call chain:
     LabVIEWSMTPClient.lvlib:Send.vi:2280001
     Send text message to phone.vi
 
Simple error handler explanation is incorrect username or password which I've checked a ton of times and with multiple gmail accounts and this simply isn't true. I admit I'm not well versed in STMP or SMS.
 
Any help would be great thanks

DAQmx choose channel to display on different waveforms

Hi NI Community,

 

I've been using LabVIEW to do some data acquisition with DAQ Assistant. In my example, you can see that I choose different channel from Dynamic Data (DDT) and display on different waveform screens. 

 

How can I do similar task but with DAQmx? 

 

Thank you!ask NI.PNG

Local variables or arrays

May 6, 2020, 6:56 pm

I made an initial program where I stored some normalization data (noise (N) and reference (R)) to measure transmission (T) of a optical device in function of wavelength. Each measurement captures a one dimensional array, (Signal, S). Now  T = (S-N)/(R-N).

For a single vi, I used some local variables to store R and N, as a way to plot each measurement instantly in function of time (my time delay between measurements is a few seconds).

 

Now I need to do a multiplexing of this measurement (using an optical multiplexer, where each channel is not identical and each Noise (N) and Reference (R) is not the same (so it is called Ni and Ri).

 

What is the best way to approach this? Local variables seem to be painful way to do so, but since I have a bunch of parameters for each multiplexed channel, it seem to be the easiest way (and now I am not able to move forward).

Is the right way to do this by making a two dimensional array and start appending the data and then just read columns or rows?

 

I used Labview long time ago, and I am not a programmer (I did programs to capture data by GPIB) and some minimal data processing and saving.

 

Thank you,

 

Gaston

I'm trying to use TDMS Flush method to write data into a HDD file periodically, in order to avoid data lost when system crashed or power failue occurs.

I forced system reset when the test VI running, then I get a TDMS file with several KB size, but I can't open that TDMS file. the following pics show the detail. 

 

78ef1a96ab53660b293c7694224674b.pngthe tdms file size is 7KB, seems the data are stored.

generating -/+ voltage with NI-USB 6009

Hello NI forum :). It's nice to join such a community 🙂

I hope you will be able to help me...

 

Is it possible to generate with 6009 card output signals outside 0 - +5V range?

 

I successfully generated a differential signal to run galvo by connecting my 6009 to a computer.  On AOO I generate a 0 - +5V signal and on AO1 constant 0V.

Is it possible to change this configuration/ add something to a program program and to generate differential -10 + 10V signal

(especially since the card accepts such input range?)

 

Thank you in advance for your help

QMH with DAQ and Serial I/O with Shift Register or TypeDef

May 7, 2020, 3:02 am

Hello Together,

for some time I was trying and searching the forum but first I don't get it and second I don't understand why.

 

my task:

I'm building up a Test controlled by serial and I/O Commands, NI Hardware is PCIe-8430 and PCIe-6323 with an QMH, Labview 2015.

I have an Event Loop, a Message handling Loop and a "Working Loop"

 

within the working loop I'd like to send the commands and read the I/O's / serial.

 

on the first run I initiated the serial Visa and the DAQ I/O's in a case in the Working loop and tried to store the names in a shift register:

WWolf78_0-1588844644986.png

 

when I try to Read/write the Serial (as well as the I/O's) in another Case within the Working loop I get an Error.

 

to keep this still simple, I tried to store the Names in an TypeDefCluster:

 

WWolf78_4-1588845420245.png

 

 

WWolf78_1-1588844753408.png

and read from those:

 

WWolf78_2-1588844884573.png

 

I get an Error as well.

 

the only thing that work, is initiating them BEFORE the "working Loop":

(which I'd like to avoid)

 

WWolf78_3-1588844976454.png

 

 

How can I initiate the Serial and I/O's within one Case in a While Loop an access them in another Case within the same While Loop?

 

 

Thanks in Advance!

I am using the 'Watlow Standard Bus LabVIEW Driver' project with the example vi provided.  I have the IP Address, and can Initialise comms with no issues.  I can also run some commands, such as Parameter 56031, to read back the Thermocouple value.  The vast majority of commands give the error as shown in the attached pic.

trend fitting - 'x' data

Hello all.

 

Trying to build a sampling vi with trend fitting.

vi. is attached (using express thing for now, I am worling on another vi using primitives but my knowledge there is not so good...

 

So, 

the issue I am having is that the dynamic data does not contain both 'x' and 'y' data, it only has 'y' data. the 'x' data is just in a header for the spacings.

I have added a loop to inject x values.

 

there must be a better way to do this? some advice would be appreciated.

 

I am also getting an error when I run the vi. - the system of equations cannot be solved because the input matrix is singular.

 

My third problem is that my non-linear coefficients array is only displaying 1 value when it should be displaying all three of the coefficients.

 

any help appreciated.

Alternative to nested case structures??

Hello, 

 

I am currenly making a simulation of using a chromatography column using LabVIEW NXG. I haven't come far yet, but I already see that I have too many nested case structures. 

 

Some of the logic I have in there is: 

Has the user pressed "condition"-button?

       If True: Is the column empty?

               If True: Is the selected conditioning volume less than or equal to 0? (invalid number)

                         If False: Is the conditioning volume less than or equal to 10? (maximum volume this specific column can hold)

                                      If True: valves open and conditioning starts. 

 

The question is: Is there a cleaner way to do this?

 

Thank you in advance!

Hi all

I have a problem with visa read. I am reading 566 bytes with start frame 0xCCCC by Labview. some times Labview shows 3 0xCC bytes I mean 0xCCCCCC (on data1 display) what is the problem?

I have checked my data on terminal (with other softwares) there is no extra CC byte and micro works correctly on the other side

could it be for high baud rate?

I have attached my VI

Thanks

Hi folks - I'm making an error handler, and I'd like to make quasi-intelligent use of the tags.  I see stuff in error sources like <ERR>, <append>, >b>, </b> and am sore filled with longing to make use of them😍.  They seem to live in the native General Error Handler system.  Does anybody know of any documentation on them?  Are they worth fooling with? Thanks guys, paul

Unit Test Framework + lvlib

I'm using LV2017SP1

 

I've got some related VIs in an lvlib.  I'd like to generate some tests for them with the Unit Test Framework.  I context click on a VI and select Unit Tests>New Test and I end up with the error:

 

"An error occurred when creating tests(s).  LabVIEW cannot create a test for this type of file.  Vi name "<My VI Name>.vi"

 

I extract the related VIs from the lvlib and add them to a project file.  I can then create tests for them successfully.

 

Does the Unit Test Framework work for VIs in an lvlib?

 

Thanks for the help...

Posting an event from shared object (so, LabVIEW RT, Linux, cRio)

Any way to do such a thing on a RIO Realtime Target? Posting Events to a LabVIEW Event Structure From a Dll  

 

It decribes how to post an event from a windows dll. It feels like I'm missing some headers ("excode.h"?) on the RT Target.

 

In the end I want my shared object to notify the Labview code about an event and maybe pass some values, but that's not mandatory since we can get them by a getter().

 

And yes as a workaround, I will implement a polling mechanism, since timing constrainst are not so hard (few miliseconds)

 

Any help appreciated 🙂

CAN Transmit Signal only once

Dear Labview Users,

I am using the NI-XNET palette and, for test purpose, I would like to send one signal only once, avoiding continuous repetition based on information written in the .dbc files.

I tried to stop the session immediately after the write, but it seems that in this way the transmission never happens

 

Thank you very much for all your kind support
