Program associated with the creation of a virtual instrument of Lab View. Please help me

I have a question with program associated with the creation of a virtual instrument of Lab View. 1.Create of virtual instrument based on the NI 9401 module fitted to the chassis NI Compaq DAQ (Ni-cDAQ-9172). Creating a virtual tool needed to implement the following counting impulses in impulse series, visualization of data through a digital indicator, comparing the number of impusite with pre-set value, that value can be assigned by the user. Indicator light when reaching in reaching the set number of pulses, the opportunity to reset the meter of a button on the front panel. Switch to digital output in reaching the set number. I hope someone can help me.

What is your question? You've described what the program is supposed to do, but it's not clear what you're asking about. Do you need help getting started? If so, have you gone through the LabVIEW tutorials? You and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free. Have you looked through the many examples that ship with LabVIEW for data acquisition?

I need a solution for a lab view apllication and installer problem

I ,ve already deployed an application and an installer, when i run the executable and the installer on my laptop it run well,
but when i run them on a computer that does'nt have a labview it gives me a messege says that i need to install the labview run time engine 8.5
actually i 've included the run time engine to the installer and i 've installed the run time engine from labview 8.5 cd,
but it still give me the same messege.
information you might need:
I'm using in my project the following:
-network shared variable
-data base connectivity functions
-report generation functions
-visa functions
so if any one can help me with this up?????????

Application builder for Lab View 8.6.1 , 2009 SP1 and 2010 SP1

All 3 Versions seem to have huge flaws. With 8.6.1 When trying to build and application I get a duplicate name error and the application won't work. With 2009 SP1 I get Error 1003 broken VI when I have no broken VI's. Again Application won't work! With 2010 SP1 After the application is built for some reason lab view can no longer find the Excel sub VI's no matter how I place them in the build. And again application doesn't work. With all 3 versions the Vi's and over all programs work perfectly in the development environment. The application builder seems extremely flawed.
I would currently like assistance with 2009 SP1 problem the Error 1003 broken VI. I have reinstalled and rebooted my machine several times , tried including as much as possible in the build and still get the error about a broken VI. That works perfectly in the development environment. Please HELP?
Thank You

LAB View crashes changing background colour

My LAB View runtime application (7.0) crashes sometimes without error message when changing the background colour of my frontpanel. My operating System is XPP.

We have reproduced the crash with the development environment and with the runtime version (.EXE made with application builder).
Enclosed are 2 word files: one from development crash and one from runtime crash.
The runtime crash is from a computer with visual studion 2003 installed, so I made some visual studio debug snapshots.
At the development crash, there are no internal errors to investigate!

Lab view programming to control the printer

Hi,
As part of my senior design, I am working on LAb view programming. Though I know some basics of lab view, I don't know how to apporach it in the right way. Our device is a dispenser (ink jet printer) which has to dispense user defined amount in user defined location. lab view program has to be interfaced with the printer to do so. I know some basics of lab view and currently I don't know where I am heading to. I have also read the one discussion forum on Lab view FPGA to control an inkjet printer which discussed about FPGA module.
Thanks,
Sundeep

No, I'm saying that depending on the level that you are interfacing would determine whether the FPGA would be a good answer. If you are interfacing to an existing inkjet printer, where you may need to just provide it with the appropriate values through an existing interface, then FPGA would probably not be the answer. If you are connecting at a lower hardware level where you need to directly control the print head, positioning "stuff" etc., then it might. But as I said, and you have reiterated, it is expensive. FPGA allows you to through "software" define a hardware logic. It is particularly good for those things that need very critical timings between signals as it basically programs a digital logic card, therefore the timings are no longer software/operating system dependent, they are in hardware, with outputs and internal signal changes dependent on internal, hardware, clock transistions. You mention that the printer is an epson inkjet. Are you talking a standard, plug it into a computer, epson printer? Are you expecting to "hack" its hardware to get control of those functions you mentioned, like user controlled ink quantity, etc.? You will have to tell us what you have in a little more detail, and what you expect to have to do. Interface to a printer can be hooking up a parallel, or usb connection and sending the codes to print (which in LabVIEW can be its own hurdle!) to the extreme of cutting into existing hardware to introduce "internal" control signals that substitute for the original. The first step to trying to solve your technical problem is being able to describe what it is that you are trying to do, in as much detail as possible.

Why does Lab View add control elements to some driver VI's!

Hi,
I have downloaded a driver project that was developed with Lab View 2009sp1. Now I will this project use with LV2010.
To do this I have the library installed in instr.lib. But when I opened some VI's I discovered that Lab View have added control elements.
Why is it so and how can I stop this behaviour?
Solved!
Go to Solution.

Surely that didnt just happen because you saved it in 2010. You downloaded a new set of drivers for 2010 from here: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=AFAA2CBD85041C96E04400144F1EF8...
The second driver has more features.
Also, note that the two modes are different, in the second case you are specifying the current where as the first one is a constant current configuration for the load.

I nead help in finding Lab View drivers for some instruments

Hi to you all
I am looking for some drivers for some instruments ( the list is add ), i have trayed to look for them in the NI site ( Search Instrument Driver Network - http://sine.ni.com/apps/we/niid_web_display.drv_search ) but with no luck - the specific instruments drivers were not there.
I trayed to look for the same instrument series but again with no luck
I tryed to look for the Lab View drivers at the HP site and Agilent site but the drivers that thay have are not ! Lab View drivers but self developed drivers for the instrument.
If someone maybe has one or more of those drivers, if someone know of a site that i can find one or more of this Lab View drivers or any help at all in finding this Lab View drivers will help me a lot
thank you all in advance

I agree that Christian is sending you in the right direction. I think you should be able to find about 75% of the instruments that you listed. Some you will not find and will have to develop the drivers yourself. There is a wizard in LabVIEW 8.X to help you with that.
I know from experience that several of the instruments that you listed do have drivers, so keep trying.
Hope that this helps,

Getting error messages upon startup after installing Lab View 5.1.1.

I have recently purchased a DAQ system along with a computer, which uses a readout program written in Lab View. however, after installing Lab View 5.1.1 on this same system, I started getting some error messages and the readout program no longer works. Here are the error messages:
"The \SystemRoot\system32\drivers\nidmmk.dll device driver could not locate the entry point ?single PointWrite@mdsSimpleDIGPortPrimitive@@UAEXKKKAAJ@Z in driver Nidaq32K.sys"
as well as
"The ordinal 2011 could not be located in the dynamic link library nidaq32.dll. An error occurred while loading VT Digital buffer write.vi"
I would greatly appreciate any help I can get.

Hello,
Installing LabVIEW should not effect an installation of NI-DAQ. However, it seems to me that we may have installed a different version of NI-DAQ on top of the current version. This is very possible because the old LabVIEW CD�s contain NI-DAQ on them.
In this case, there is not an easy solution, we could try uninstalling and reinstalling combinations, but it will probably save the most time and effort to uninstall all National Instruments products and reinstall them. The best way to do so is from the ADD or REMOVE Programs utility from the Control Panel. Then we want to remove the following registry keys (BE SURE TO BACKUP YOUR REGISTRY!!)
HKEY_CURRENT_USER\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ or \ISA and delete registry entries containing any keys with 1093 in them.
Do not worry if any of these trees are not listed. If you have Administrative rights, and you still cannot delete these keys, that is also OK. Continue with the remainder of the process.
Make sure that you do not have any of your own VIs or other files saved in the "C:\VXIpnp", "C:\Program Files\National Instruments", or "C:\WINDOWS\nidaq" folders. If you do, copy them to a different location. If you are concerned about keeping old virtual channels and your SCXI setup intact, then backup the "C:\WINDOWS\niconfig.daq" file, too. Delete all folders and files mentioned above.
Note: If you have Windows NT/2000, replace "C:\Windows" with "C:\WINNT" in the paths listed above.
Once these steps are taken care of, we should have clean system. You probably want to reboot and then reinstall the software. You should install development environments first, and then install drivers.
Just let us know if this does not take care of the problem, or if you have any questions on how to complete a step of the process.
Best regards,
Justin T.

NOTE: Turning off virus scan programs greatly increases the speed of uninstalling and reinstalling.

Some of these instruments do have drivers or ones for very similar instruments. They are the 8920,4416,8657,8901,8560,TDS540. I haven't gone to any of the vendors sites to see if there were any more you might have missed. You should also know that drivers labeled as 'plug and play' but not LabVIEW, can be converted to a LabVIEW driver.
If your search still comes up short, you have a few options. At http://www.ni.com/devzone/idnet/default.htm you can make a request for a driver. NI does drivers based on demand and there is no guarantee when or if they will develop one. You can develop them yourself. The above page has links that will help you with this. Developing a driver is not an especially difficult task. You can use the Instrument I/O Assistant or just regular VISA Read/Write to control the instrument. You can hire someone to write the drivers for you. NI has the Alliance Program at http://www.ni.com/alliance/. Some members specialize in driver development. You can choose one of them or someone local.

How to configure a shell and tube heat exchanger with Lab VIew to get data

HiI
In our undergraduate chemical engineering labboratory we want to configure our shell and tube heat exchanger with a DAq and Lab VIEW to get information about the temperaure (of the cold fluid stream being heated), the pressure (of the steam on the shell side of the heat exchanger) and the flowrate (of the water being heated).
Can anyone suggest thermocouples, pressure transducers and flowmeters to fit between the heat exchanger and the DAq?
P.S. the heat exchanger is already fitted with thermometers, a pressure gauge and a rotameter but we don't know how to connect these hardware to the DAq
Solved!
Go to Solution.

It sounds like you have enough information to pick out appropriate sensors, you just need to do the research. I would start looking through the Omega catalog, or give them a call - they're usually helpful. I can't take the time to spec out parts for you - that would be a lot of time spent on someone else's project. Most pressure sensors put out either a 4-20mA or 0-5V signal, either of which you can read through an analog input on a DAQ; measuring a 4-20mA signal requires a resistor to convert to voltage. Most of the NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware does support reading thermocouples. For accurate readings, use a device that has built-in cold junction compensation - for example, the SCB-68 connector block - and for the most accurate readings, get a board specifically designed for temperature measurement.
For the flow measurement, a standard, simple solution is an orifice plate. You put a differential pressure transducer across it, look up the appropriate equations, and use them to calculate the flow rate given the density of the fluid (which you'll be able to calculate from the pressure and temperature, since steam tables are widely available). There are other differential pressure devices available as well - at a previous job we used a V-Cone from McCrometer. If you call them they'll spec one for you - but get an approximate cost first to make sure it's within your budget.

How to get lab view to display my plot in DB

hi guys
i desigED n an operational amplifier to determine the gain product band width using a 741 chip and the gain of the circuit is 1000, meaning that the gain bandwidth PRODUCT will occur at a frequency of 100hz. but i have a problem, when i start the frequency sweep from the function generator from 10 hz to 100Khz which IS the final frequency value i have set for the program. when the lab view program stops and i export the data to excel sheet i will be getting the DB axis value in a SMALL VALUES AND IN DIFFERENT UNITES WHEN I PLOT THE GRAPH USING EXCEL, while the frequency is in log10.
pls can any one tell me how to solve this problem to start getting the right cut off frquency on the graph. find aattched my vi and the excel data from the vi that is in a different unit not in DB

thanks Jeff Bohrer for your reply, what i mean is the y-axs of the plot is in DB aleady, but when i export the data to excel i will be seeing the gain in 0.8, 0.7,0.4 which is not normal, which will not give me the -3db point of the gainband width product of the circuit
What you want to do is plot the Log(10) of the frequency on a linear axis!!!!!!! The export - exports the values not the axis scale. exporting a log(10) of the Y axis will export the log of the axis- (of couse, you could change the graph axis scale in Excel too...... but)
