I want to get and set windows system time through lab view

Hi
I want to get and set windows system time with the help of lab view 8.5.
please help me out.

You can use the call library function node. Once you drop it on your block diagram double click it and you will be able to select the dllyou want to use. Choose kernel32.dll and you will see methods listed called getsystemtime and setsystemtime. Use those

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...what should I do?

Hi Arika,
The drivers that you need to install to make your executable work depends on what your executable is doing. To get started, you need to have the LabVIEW Run-Time Engine installed on your target machine (the Win2000 machine you are planning to use) in order to run your executable. Next, you need to determine what drivers your executable uses, if any. For example, if you are using GPIB instrument control, you will need to install the NI-488 drivers on your target machine. If you are performing data acquisition, you will need to install NI-DAQ drivers. If you are doing image acquistion, you will need to install NI-IMAQ drivers.
All these drivers are available for downloading on ni.com. To get the drivers, go to ht
tp://www.ni.com/support , click on the link that takes you to Drivers and Updates (under Option 3), and click on the links to get to the driver(s) you need. For example, if you need the LabVIEW 5.1.1 Run-Time engine, click on the All Drivers and Updates by Application link on the main page (http://www.ni.com/softlib.nsf/). Then click on the LabVIEW link, Windows 2000, Run Time Engine, and then you will see the link to get to the page to download the LabVIEW 5.1.1 Run-Time Engine.
I hope this information helps.

Using Adobe 11 reader, now comes up with an error, once file is opened. 'Invalid plugin detected, Adobe reader will quit. Closes the program so cannot view PDF files. Running windows 7. I have uninstalled and re-installed Adobe still the same. HELP

Using Adobe 11 reader, now comes up with an error, once file is opened. 'Invalid plugin detected, Adobe reader will quit. Closes the program so cannot view PDF files. Running windows 7. I have uninstalled and re-installed Adobe still the same. HELP

Sounds like something has been added into the Reader folder. I would recommend uninstalling, running http://labs.adobe.com/downloads/acrobatcleaner.html, removing any left over parts of the Reader folder (this might have been the problem), reboot, and reinstall. Hopefully that solves the problem. For future question about Reader, you should consider asking in the Reader forum, this is not it.

Video freezing up while running Lab View 10

I am using Lab View 10. My video will freeze up every so often. Somtimes labview will abort by itself? I can run other applications while lab view is frozen. Is it a lab view programming problem or a possible video card problem. The main VI is 1.7 MB. I am running Windows Xp 32 bit. CPU 2.4 Gig, Memory 4 gig, Video Nvidea GeForce 8400 GS. It appears to be a video refresh problem. I can have a screen with two different application screens on top of each other. Can someone confirm that the video card is the issure?
Any suggestions would be helpfull.
Solved!
Go to Solution.

I'm having trouble understanding the exact behavior of 'Video' on your system. Are you having trouble displaying specific VIs? (Controls/Indicators, Updates on the Front Panel, Etc) Are you seeing generalized glitches only when running LabVIEW? If you can provide further detail on the behavior, it will be very helpful in providing meaningful troubleshooting steps of the system.
Thank You,

Lab View crashing when creating new bound variable

Hi,
I have to connect to an OPC server from Lab view and have played around a bit with the OPC client options.
I would like to use shared variables as that seems like a handy way to access the needed variables. I have followed the instructions in http://zone.ni.com/devzone/cda/tut/p/id/7450 .
However when i use the create bound variables feature LabView crashes when i browse for OPC tags, step3 under "Create Shared Variables that Connect to the OPC Tags through the I/O Server". If i try to expand the node "OPC1" LabView crashes. I try to access the built in NI OPC server locally.
Also during this process LabView gives warning box saying "Configure OPC server to run with an identity of interactive user". we did try the the steps in http://zone.ni.com/reference/en-XX/help/371618G-01/lvdschelp/config_local_opc_serv/ . However the The interactive user button was disabled under NI OPC sever properties.
Is there something i have missed? Something that needs to be configured before going through that tutorial?
I run LabView 2011 on a 64 bit Win7P computer. The DSC module and the NI OPC Servers are installed and seem to work (when running the OPC examples ).
Thanks.

Hello AmritaNikhil,
Thanks for the post, I have a few questions for you about this issue.
What versions of NI OPC Servers are you using?
Is the server hosted on your local machine or on a remote machine?
Are you able to successfully connect NI OPC Servers and NI OPC Quick Client?
Have you been successful in using OPC IO Servers in the past or has this issue occurred since you have started your application?
Can you consistently reproduce this crash?
You can try to work around this issue by using Network Items rather than Project Items when creating bound variables in the Create Bound Variables window. Please try this option and let me know if you have any additional information about your application that may be helpful in solving this issue. In addition, I have also included a link to a similar post. Hope 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,

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)

Ability to view multiple files in ONE window

I can see here that this is not a new topic really but the thing with Acrobat 9 is so frustrating that it is just unbelievable.
This is another pearl:
Acrobat 9 "lost" its predecessors ability to view multiple files in ONE window. After opening four only documents I cannot see anything on the screen because the toolbars on each individual window cover all necessary view and nothing is left for the actual document. And sometimes I need to open 20 documents!
This is ABSOLUTE DISASTER!!!
I found some explanations from Adobe on the Web that are more than a year old.
I was sure that by now this unfortunate mishandling of that feature (apparently it was dropped out from A9 deliberately - WHO'S IDEA WAS THAT?) would be somehow restorable.
Would anyone happen to know if this feature can get restored to how it was working in A7 or 8 (without the need to uninstall A9 and install A8)?

No, it can't be restored, unless Adobe decides to change the way Acrobat works (which is possible, but not likely).
By the way, it was Microsoft's idea... Adobe were just following their example on this.
You can make a feature request here: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform

How do I view multiple images in one window?

How do I view multiple images in one window? I want to compare images side by side, not in tabs.

Thank you, Barbara. I found that I had to close the program after I turned on "allow floating documents" and restart, before I was able to go to "float all in windows".

Communication between Lab view and Controller via USB

USB communication between C8051F320 and Lab View. I try doing methods given in the NI site(http://zone.ni.com/devzone/cda/tut/p/id/4478) and atlast, it gives me error −1073807302 so if any one can answer my question please do post me the details concerned to it.

My devices show up as NI-VISA USB but I'm not sure if that makes a difference and I'm not using USB RAW either. One thing that you can run is a VISA Property node like below and see what it reports. Also, what version of VISA are you using? If you are not using 4.0, you can download it from http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C0E91?opendocument&node=1....

How to get bode plot in lab view

Hi all,
I'm just starting with lab view.
We have NI PXI system.
I need frequency responce of a servo motor i.e. bode plot,
I'm using labview 8 ,we have PXI 7352 motion controller.
I'm very confused as where to start and what is the in put to the motor.
can any one help me?

Hello,
I'm not so sure that using a motion control card is the way to go about finding the frequency response of a servo motor. In order to do this, you would give the motor a varying sinusoidal voltage and then measure the voltage output of a velocity sensor. Here is a link to a document that goes through the process: ftp://ftp.ni.com/pub/devzone/epd/lab5_frequency_response.pdf

How to control a NI USB 6210 from a Lab View program?

Hi,
I started today with Lab View with some earlier experience long ago.
While it took me only about half an hour to get my first program running (great), installation time nor included (of course), I meanwhile read documents for some hours and cannot find out how to control measurement hardware in Lab View.
I want to use a USB 6210 to set a 1-bit digital port. But at the moment there is no USB6210 available so I wanted to write (or do you say draw ?) the program without it and if possible simulate the hardware.
I drew DAQ Assistant into my block diagram and selected digital line output but get "No supported devices found". I don't know if the appropriate driver was installed during Lab View installation.
Also I don't understand the mechanism between DAQmx, tasks and the real hardware. Now I have a "Digital Bool 1Line 1Point" Control in my block diagram. How do signals get from program flow to hardware pin? How can I create a simulation for not connected hardware?
Any help is greatly welcome
Thanks a lot
Martin

Launch MAX, it was known as Measurement and Automation Explorer, there should be a shortcut in your start menu / desktop. Under devices and interfaces you can find your hardware and open test panels to control it. This is the first place to ensure your hardware is working. If the device isn't seen you'll need to install the drivers and DAQmx software. If it is there, great.
Now launch LabVIEW. The easiest way to control hardware is using the DAQ Assistant. It has many limitations and isn't recommended for large applications. But for something quick and dirty it works fine. You'll find it under the Measurement I/O >> NI DAQmx palette on the block diagram. If it isn't there you may need to reinstall the DAQmx drivers. This can happen if you installed DAQmx before LabVIEW.
Also you'll find under Help >> Find Examples on the toolbar, many examples on controlling hardware. Feel free to post some code if you are having problems.

Is there a way to view just one open Finder window (without any other Finder or other application windows coming into view) from a Desktop hot corner in Yosemite?

I just upgraded to Yosemite from Snow Leopard on a MacBook Pro. Previously, I could view just one open Finder window by viewing the Desktop via a hot corner and then selecting Finder from the Dock. This would pull only the top Finder winder into view, without showing any other open Finder windows, and most importantly, any other open application windows. I could then easily drag files/folder from my Desktop into the Finder window (which I do A LOT). Since upgrading to Yosemite, whenever I use the Desktop hot corner and select Finder from the Dock, it pulls every open application and Finder window back into view, putting Finder in front.
Is there any way to view just one already open Finder window (or all Finder windows for that matter) without seeing all other open applications, without having to Hide the other applications or using Spaces?

Yes I've created an Automator Application that does the job, but the "watch me do" function that does the Mail Merge is a rather Clunkey work around, as the mouse moves all over the place, thats the part i want to remove and replace with a script, or work out a different way around it that avoids the "watch me do" function.
Is this Possible? or where/who is there i can ask to write me a script, im not a novice to scripting, but i am a novice to Applescript.
