Write special text to EXCEL using report generation toolkit

$
0
0

I have been searching for a solution to this issue for quite a while but not able to get a good one yet. What I try to do is to write an array of text data to EXCEL with the Report generation toolkit. What makes this difficult is some such array elements are of the pattern resembling to an exponential numerical value, such as "20e00". In this particular case I would like the exact text of "20e00" withing the quotation mark to be written. However, with my simple code as attached, EXCEL sheet gets "2.00E+01" or 20 depending how I format in EXCEL. So my question is, is it possible to have some further configuration or formatting on the LabVIEW side to get output as I expect?

 

Thanks,

Tao

LabVIEW Runtime Engine

$
0
0

Hello!

I have a LabVIEW stand alone executable installed on a workstation. This old executable was installed using an "Installer" .  I did not build this executable. Today, I built a new stand alone executable and I wish to distribute this new executable using an installer. For this new executable, should I include within the "additional installers"  the default LabVIEW Runtime engine? I am concerned about two, potentially different, LabVIEW Runtime engines being simultaneously installed. A second concern I have is overwriting the existing Runtime Engine and breaking the old executable. What should I do? Any info on how LabVIEW handles differences in Runtime Engines? Thanks! -  John

Outputting Accelerations to Excel and and Troubleshooting an Increasing Signal

Howdy, 

 

To preface this post, I am an undergraduate student that is very new to learning LabView and am here to learn. 

 

I am trying to build a LabView program to process the signal from a 3 axis accelerometer and output the values to an excel file. (it should be noted that this current program is set up for only one axis) The current problems I am having are the following:

 

1.  When running my current program and viewing the acceleration in a waveform chart, the signal seems to be exponentially increasing as time goes on. You are able to see the acceleration changes when the sensor is moved, but the signal itself is constantly increasing. This can be seen in the attached PDF file.

 

2. When outputting my accelerations to an Excel file, the worksheet shows numerous rows and columns showing different times on corresponding to every row and column. I haven't been able to make any sense out of what it is actually outputting, but my intent is to simply have a worksheet that contains 4 columns for time, x axis acceleration, y axis acceleration, and z axis acceleration. 

 

Any advice or tips someone can provide will be a lot of help to my project. Thanks!

hello everyone I am using NI PCI-6110 card, I want to achieve signal output and acquisition by this card .A is PZT 1 , B is PZT 2. A is the excitation source, frequency is 30KHz,the voltage is ±10v, B is the receiving source, the voltage is about tens of mv. The distance of AB is 120mm, the propagation time is about tens of us, how do I want to measure the time of propagation, regards wys

Error in Access 2016 Database Acquisition - LabView 2019

$

0

Good afternoon friends, please help with a problem. I am acquiring information from a database with password and several tables, created in Access 2016. The UDL is configured from the same VI through a constant string. When executing the VI, the program correctly acquires the information from the database and complies with what is programmed. The problem occurs when you stop the program and start it a second time. The VI closes immediately and the following error message is indicated:

 

Exception: Access violation (0xC0000005) at EIP=0x503A704A
Version: 19.0 (32-bit)
Possible Cause: C:\Program Files (x86)\National Instruments\LabVIEW 2019\vi.lib\addons\database\Connection.llb\DB Tools Open Connec (String).vi

 

Because of this error, the program closes and when restarting LabView the same program can be executed correctly once, falling into the same problem when trying to test it for a second time. This is generating a headache to continue my development.

 

Initially I thought that there is some error in some part of the programming, but to verify it I reduced the tests to a basic DB of acquisition of DB, sampling of tables and closing the DB. Now I see that the error remains the same. Please, help me by indicating what the problem may be, I reinstalled LabView 2019 in 32-bit version but the problem persists. I attach an image of the basic DB acquisition and the error.

Unsuccesful build installer: Upgraded product

I've been searching the forum for a solution for this. 
I can't build an installer for our software since it keeps failing on an upgraded product. I get the following error:

=========================

The following product(s) are not found on the system or have been upgraded:
NI-DAQmx Application Development Support 18.5

 

Error 7 occurred at CDK_Utility_GenerateErrorCluster.vi -> CDK_Validate_DistParts_2010.vi

Possible reason(s):

LabVIEW: (Hex 0x7) File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.
=========================
Nonexistent GPIB interface.

 

I tried updating the NI-DAQmx and Labview drivers. Got a "can't install version 18.5 since a newer version is already installed" once, but I think that's the problem? Why doesn't labview automatically update the version used in the builder? How can I manually do so?

Output the source for acquisition ticks

$

I am acquiring an analog signal from physical channel A with a frequency f and underlying TimeBase of 100MHz from the DAQ card (internally, i.e. no external trigger source).
On physical channel B I now need to output a digital signal that coincides with the ticks used for the acquisition of channel A.
Specifically, whenever the DAQ board generates a tick to start the acquisition of one sample on channel A, I want that same tick  to simultaneoulsy be output on channel B. This means that I do not want to specify a frequency for the output of the ticks on channel B, but rather 'redirect' the tick signal to an output.
I am using the PCIe-6376 card.
The manual states that "AI Sample Clock Timebase is not available as an output on the I/O connector." Does this mean that what I am trying to do is impossible?

Attached is my best attempt, however, I am having trouble getting the ticks to be output on channel B.

Keysight 34972A reduce number of switching processes on 34901A 20-Channel-Multiplexer

Dear all :-)

 

I am using Keysight 34972A in combination with the 34901A 20-Channel-Multiplexer to measure voltages.

Right now I only measure one voltage. later there might follow more.

 

Everytime, I use the measure voltage block the device switches the relay. If I choose a fast measure rate, the relay will be end of life very soon.

Is there a way to measure one channel without the relay switching all the time? (actually it only has to switch the relay when I change the channel, right?)

If someone has an idea I would be very happy :-)

 

thx 4 input

 

Kind regards

Anna <3

display image IMAQ

Hi, 

I am new to Labview and will appreciate any help I can get. I'm am trying to display an array as an image and nothing is being shown in the image window on the front panel.

 

I have a 2D array and used IMAQ ArrayToImage, I have tried just creating an indicator to display the image on the front panel. I also tried using IMAQ Windraw. Both attempts have not produced anything.

 

I have managed flatten the 2d array and use draw flattened pixmap, but I need to be able to select a ROI and then do further analysis on the image.

 

Thanks for any help,
