Can any one please tell me how to write labview program for data logging in electric motor bike.

Can any one please tell me how to write labview program for data logging in electric motor bike. I am going to use CompactRIO for getting wide range of data from various sensors in bike. I need to write labview program for data logging of temperature, voltage and speed of the bike. Can any one help me?

Yes, we can.
I think the best place for you to start for this is the NI Developer Zone. I recommend beginning with these tutorials I found by searching on "data log rio". There were more than just these few that might be relevant to your project but I'll leave that for you to decide.

Using APT ActiveX methods to create a labview program for BPC 203 3 channel Benchtop Piezo controller

Hi Everyone,
I am really very new to Labview and i am in great need for some help.I am assigned a task where i am supposed to create a labview program to control or moniter a BPC203 3 channel benchtop Piezo controller. I created a program with the help of the instructions provided in the APT-Labview guide provided by Thorlabs.But th program doesnt run . Whenever i try to run it i get the same error which says that "Control HW Communications disabled".I have attached a snapshot of the error message.So i tried to create a small program in labview which would read the volage output.Even there i got the same error message.I suppose there is some mistake on my part which i am not able to correct due to the lack of proper knowledge.Could anyone please help me to solve this problem.A slight elaboration would be highly appreciated.Also i think the error lies in the use of invoke node with the get Voltage output method. I am not sure whether the parameters i have provided to the invoke node are correct.Any help of any sort would be highly appreciated.

Hi
I had the same problem today. However, I noticed that the piezo controller has 3 channels with separate slots and they are packaged in the same box. Therefore the whole box has a serial number, probably something like 71822280, and this is written with large letter. Now, in order to communicate with any of the channels, this does not help, but one needs to communicate directly with the interested channel and they have thier OWN SERIAL NUMBERS.
For example channel 1 (my X direction in the nanoMax stage) has serial 91822281, Y has 91822282 and Z has 91822283. So try looking if you have the right serial number Hopefully you found out this yourself but this might help others, I took me3 hours to get this thing working when I started to plug-in the cables and everything.

How do I make a labVIEW program for a linear CCD camera?

Hi, I'm pretty new at LabVIEW and I'm having a hard time figuring out how to connect my linear CCD image sensor (Toshiba TCD1304AP) with my computer. I know I need a DAQ device, what would work best for this particular CCD? After I got that connected, I need to create a LabVIEW program that displays the light detected by my CCD. Does anyone have a similar program or template I can use as a model? Any help would be appreciated. Thanks.

Hello,
I'm not sure the type of signal that is generated as an input to a DAQ device. This could either be an analog or digital input. The signal type will determine how you make your program in LabVIEW. You will also need to correlate the signal level to the light detected. That will be determined by your sensor. I don't have any programs or templates for this, but if you look at the basic analog or digital input examples, you might get a good starting point for DAQ device programming.

LabVIEW program for HP 4194A Impedance/Gain-Phase analyzer

Hi All,
I was wondering if anyone has a labview program already written for a HP 4194A Impedance/Gain-Phase analyzer.This instrument measures the impedance,capacitance,dielectricloss etc as a function of frequency.The problem is I have to write down each and every reading. I was wondering if anyone already has a program written for extracting the data and storing in a excel or a txt file.please post the program if you have it.
Thanks
Manoj

Here is an example. It represents some of my early work, but it is functional. With this one, you can get specific readings, or the whole sweep.

LabVIEW programing for 32 bit micro controllers

I have been programing with LabVIEW for about a year now and found out there is a way to use LabVIEW to write code for micro processers. Did some searches and found out there is a more set up and 3rd party interface is required.
Is there a document, web cast or training of some kind that would walk through the set up?

Are you talking about the C generator? Have you checked the price? It is crazy expensive -- I looked into it once and it was thousands of dollars per year...

Labview programming for pci cards

Hi all,
I need to write a program in labview that communicates with a pci dio 96 card.
I need to set a bit to 1 (0th port and 5th bit) periodically..
how can I communicate with the pci card from the labview..
is there any driver that we can use for this..
Thanks,
Vijay

Thanks Dennis,
Actually I dont think I have any drivers installed.. Because, I used the tap test interface in MAX to find that I have to trigger the 5th line of 0th port of a pci dio 96 card to trigger my device.
I have downloaded and installed Daqmx that suits my labview version and started exploring the options.
Now, I am struggling hard to figure out how to change my requirement that I have mentioned above into an actual program in labview.
All I have is a pci dio 96 card installed, labview 8.2 and daqmx that supports my labview version. I have to make one of the lines to 1 and 0 alternatively.
Can anyone point to a tutorial or some discussion that could help me kick start.
Thank you,
VJ
Search in the examples\DAQmx\Digital folder inside your LabVIEW installation. There are several examples that should give you enough hints at how to go about that. And if you ever get at other problems there are many many more directories in that example folder. :
And an example finder to help you look for the right examples can be found in the Help menu.

FieldPoint devices and LabVIEW program for educational project

I use LabVIEW 7.1 and NI FieldPoint devices (FP-1000) for educational
purposes. I want to control a automation unit which has got 6 digital
input(DI) and 5 digital output(DO). I used the sequence structure, but
actually I am not sure the solution whether true or not.
Working principle of my system:
If "Channel 1" DI is ON, DO Channel 10 must be "ON"(turn table motor
Start)
If Channel 2 DI is ON, DO Channel 10 must be "OFF"(turn table motor
Stop) and DO Channel 11 must be "ON" (drill motor Start) and after a
delay time DO Channel 12 will ON (drill motor down)
If Channel 3 DI is ON, DO Channel 12 will OFF, a bit of delay time DO
Channel 13 ON ( drill motor up)
If Channel 4 DI is ON, DO Channel 13 and Channel 11 will be OFF (drill
motor stop) and then DO Channel 10 must be activated.(turn table again
Start)
If Channel 2 is ON again DO Channel 10 will OFF and check cyclindir
control Channel 14 will ON, after a delay Channel 14 will OFF
If Channel 5 DI is ON, DO Channel 10 will ON again while DI Channel 2
is ON.
How can I project the system with LabVIEW 7.1?
Thanks, stn

This is a pneumatic technical experiment set. Your suggestions okey
but I have already studied these subjects.I have tested a solution for
the system using the sequence structues in the LabVIEW. But if you
sent to me an example vi, I will understand the solution way.Thanks.
Working principle of my system as a summary:
Step 1: When DI 1 is ON, DO 1 must be "ON"(turn table motor
Start) while DI 2 is ON. In this case DO 2 must be "ON" (drill motor
Start) and after a bit
time delay DO 3 will ON (drill motor down),
Step 2 : when DI 3 is ON,(drill bottom level), DO 3 will OFF, after
that DO 4 will ON ( drill motor upper position) in this case DI 4 is
ON, after that DO 1 again ON while DI 2 is ON (like step 1)

LabView program for XBee

Dear forum,
I'm a senior student who has no more than basic exp with LabView and seriously need help right now. I have a wireless pH sensor system that use XBee as a mean to transfer data and i have finished everything but the last step which is read data between XCTU and LabView. Does anybody has a similar example of the program or could tell me where to start with. The XCTU gives me all the Hex code by the way.

Are you using an XBee in a dev board on the computer-side of this communication? If so, you should be able use the LabView VISA serial port VI to send/receive over the radios without having to use X-CTU.

Password for labview program

Hi all,
I am developing a labview program for a high
power microwave device. The final program will
be running stand alone on a pc attached to the
microwave device in a laboratory. To ensure
safety, I am wondering if I can set up a password
to the labview program at start up so only
authorised people can use it? Or if there is
other way to do that. Any comment will be
greatly appreciated.
Thanks.

I am pretty sure that you can do that by using a case loop outside of
your main program. You can set it up so that user(s) will have to
enter a string (which would be password) before he/she can get to the
front panel of the main program.
Within this vi, you can have an array of strings such that users can be
given different passwords (or level of authority) for more security.
After the user enters the password, you can compare the user input by
using equal function in the comparison palette (make sure the password
list is case sensitive or stuff like that or you'll have to convert all
the user input string to either upper or lower case if you want to save
some trouble). If the result of comparison is true, then they can get
into the main program, or else the program will quit.
You can also put in looping structure to make it more fancy such that
each user can be given say 3 chances to enter the correct password...
If you want to go really fancy, you could also try to put in a data
file that stores all the passwords in binary format (requires a little
conversion, of course) in a directory of the target machine that you
know exist (say WINDOWS or WINNT), and include the data file as part of
your instalation disk content, point the installation destination to
that directory. In your password program, find the target machine
operating system and then look for the file from there.
Hope it helps. If you have any questions, please e-mail me at
[email protected], and I'll try to e-mail you a copy of my code.

How use an ESP motion controller to drive an actuator by using Labview program?

Our group bought a Universal Motion Conroller/Driver from Newport company and
its model is ESP 300. Right now, I am going to use it remotely and I want
to use Labview to compile the driving program. My thought is to move an
actuator step by step in x-axis and the length of step moving is 2cm.
After moving 40cm on x-axis from the beginning to the end, I will move the
actuator one step on y-axis. Then I moving from the beginning to the end
on x-axis again. I wonder whether somebody has such a labview program
or not. Or, has anybody other sample Labview programs for the
controller to control the moving? Can you provide them to me?
Thanks a lot.
Huili Wang

Hello,
There are several examples written in LabVIEW to do what you are trying to do but they will only work with National Instruments motion controllers, as they use driver specific VIs. In order to use your controller with LabVIEW you'll need a shared library of some sort. Once you have this library you can program your controller in LabVIEW by making function calls referencing to its shared library. See built-in LabVIEW examples for 'Using External Code'.
I hope this helps. Let me know if you decide to go with one of National Instruments motion controllers instead and need help finding those examples I was referencing above.

How to run the program for specified time

Dear Friends,
I have a small problem, I want to run my labview program for specified amount of time, Say for example it might be 1 hour or 5 hours or 10 minutes or even milliseconds(The time will be specified by the user).
How to write programs for this
And I want to get the system time in an instance, how it can be achieved,
Could you please help me?
Regards,
Rathan

Hi,
Herewith my screenshot attached. There are thre inputs thres, tempX, xValue, it is in side the while loop.'xValue' will be acquired every iteration, It will be saved through shift register and acquired to 'tempX' for the next iteration, 'thres' is a constant value. I'm doing some logic, and calculating the dvalue and convert it to a string and concatenate it with end of line character, then after writing it into a file.
In the logic, inside of the functional logic I'm assigning some values dValue, if the logic is true or else dvalue will be 0
What I require is I don't want to write the dValue in to a file, if it is equal to zero. Could you please help me, how to tackle this problem?
Thanks.
Regards,
Rathan

LabView interface for SRS DG645

I need to implement a driver for my SRS DG645 module connected to my computer by an NI GPIB, does a driver already exist in LabView? I need a LabView program interface on my computer seperate of my module to control it. I read that Stanford Research Systems does not assist with LabView programming for their machines, and so I have yet to find a LabView interface created for this module.
Thanks for any help!

Hi zeddy and others.
Sorry for replying on old post but i got just the same question.
I will be using SRS DG645 for my project on LabVIEW 7.0.
Do i need any driver for it?
When i search at NI website, i found some plug and play drivers for DG645.
but there are no driver for labVIEW 7.0..
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=D62E8D508F9832E6E0440021287E6A...
Plus, the drivers need NI VISA 5.2 version to work.
Does that version with my LabVIEW?
Here is the compatibility table of Ni-VISA and LabVIEW but there is no LabVIEW7.0 in there.
http://digital.ni.com/public.nsf/allkb/CF4279A34F855AB186257B1F00003B82
Can you help me with it.
Thanks in advance.
