Measurement and automation explorer

Hello,
In my application, I want modify the offset and the sensitivity in scales of Measurement and automation explorer. Is it possible to do it in a VI and how?
Because in my application I have a menu in which there is a calibration part. In this, I would like to group all parameters of my sensors (name, sensitivity and offset) and write automatically the offset and the sensitivity located in Measurement and Automation explorer without quit my application.
Thanks for your help,Franc.

There might be a way to do this with DAQmx, but DAQmx is not supported in LabVIEW Real-Time 7.0.
Using Traditional NI-DAQ, you can only read custom scale information with Get Scale Information.vi. This VI is located under Data Acquisition >> Calibration and Configuration >> DAQ Channel Utilities.

How can I get all the options of Field Point Explorer 3.0.2 in Measurement and Automation Explorer 3.1?

I am a student using LabVIEW and Compact Field Point to implement a
senior design project in Electrical and Computer Engineering. We
have LabVIEW 7.1 and a cFP-2020 and additional modules. We are
trying to use the CTR-500 module to output a pulse train to drive a
stepper motor. We have found instructions online of how to do
this, but they all use Field Point Explorer. The instructions
make use of options in Field Point Explorer that are not included in
Measurement and Automation Explorer (the software included with the
cFP).
I have downloaded Field Point Explorer 3.0.2 and followed the
directions. Now, in LabVIEW, when I using the newly created .iak
file, I get a dialogue asking to find the SubVI: 'FP Read (Float Array
-IO).vi'. Included with LabVIEW are subvis for FP Read, but not
with the float array part. So I figure I cannot use Field Point
Explorer created .iaks with LabVIEW 7.1. So how cannot I access
the same options in Measurement and Automation that I was able to find
in Field Point Explorer?
Thanks

Hi,
FieldPoint Explorer is no longer used to configure FieldPoint systems. However, I do not think that the configuring your system in FieldPoint Explorer is causing the error.
FieldPoint systems are now setup in Measurement and Automation Explorer (MAX). Information on setting up FieldPoint systems in MAX can be found in the MAX help under: Installed Products>> FieldPoint. Also, I recommend upgrading to the latest FieldPoint driver and version of MAX. The FieldPoint VI's will be slightly different when you upgrade, so there is a good chance that this will eliminate the error.

Measurement and Automation Explorer (MAX)

where does Measurement and Automation Explorer (MAX) store virtual channel names

They are in the ivi.ini file, typically located in the \VXIpnp\WinNT\niivi directory. Substitute your OS name for "WinNT".

I get an exception error when launching NI Measurement and Automation Explorer

The CniDMFuiProvider::Initialize plug-in caused an exception in the CmxExecutionThreadPool:oWorkNonUI function in the MAX process. What is mean. I cannot access NI MAX after I ignore this message, I will have to kill the process.

Greetings nintel
This type of NI-MAX exception is associated with a corruption in some files of the NI-MAX and has been solved in the past by either removing a MAX database corruption or repairing the installation of NI-MAX. Have you tried going to Control Panel>>Programs and Features>>NI Software and repairing NI Measurement & Automation Explorer? Please let us know if any of those steps solve the problem. Have a nice day.

Is it possible to change the resolution of indivdual channels in measurement and automation explorer using a VI

Hi
I'm acquiring data on 8 analog input channels using a PCI-6052 E card. The data on channels 5 thru 8 is going to be between +1V and -1V. So for greater resolution I'm manually changing the range of these channels to +1V to -1V in the measurement and automation explorer. Is there a way by which I can make these changes directly using a VI ?
Thanks,
Shiv

Hi
Yes you can, but only if you use the "AI Config" VI. AI config allows different gains for different channels. The "channels" and "input limits" inputs of the VI accepts arrays. The first element of the input limits array corresponds to the first element of the channel array. Check the "cont acq&chart (buffered).vi" in the LV examples. There you see what I mean!

How do I increase the field of view in Measurement and Automation Explorer (MAX) Version 3.1.1.3003

I am using Measurement and Automation Explorer Version 3.1.1.3003 to view pictures on a pc that are being sent from a video camera looking through a microscope. The image I see in the viewfinder of the microscope is MUCH smaller than the image that is displayed on the pc screen. Looking through the viewfinder of the microscope, I can see ~20 mm across the object, but the display from the camera in NI-MAX shows ~4.5 mm across the object. How can I change how much of an object is displayed on the screen in NI-MAX?
The camera is attached to the microscope with a camera adapter on the top of the microscope. The lenses the camera "looks" through and the lenses used when one looks through the viewfinder are the same, so theoretically, there should be no difference in what is displayed on the pc and what is seen through the viewfinder. We have ruled out the microscope and camera as the cause of the problem, which narrows it down to the NI-MAX software itself.
I saw in the forums that you can zoom out on an image; however, this does not change the distance across an image that is seen, just makes the picture of the same ~4.5 mm across the object smaller in size.
Any ideas or suggestions?

I have attached a picture of the object's image being displayed on the pc monitor. Where the field of view (FOV) in the microscope is almost 30 mm, the FOV displayed onscreen is about 7 mm. After contacting companies various times I discovered there was a reducing lens that goes in the C-mount adaptor, but it is over $300.
I thought maybe that the FOV could be changed in in NI Measurement and Automation Exploer (NI-MAX). Any ideas?

Measurement and Automation Explorer not installed correctly

I have a trial version of LabView 8.5. Upon trying to change the Instrument I/O Assistant, I get "Measurement and Automation Explorer not installed correctly. Please install from driver CD." Well, I don't have the CD since this was a trial download.
Basically, what I am trying to do is this: I want to pull 4 variables/tags from an Allen Bradley PLC and log them to an Excel spreadsheet. I am using RSLinx to communicate with the PLC, and LabView to compile the info.
Any help would be appreciated.

Any Ideas? I have the program running right now, and I'm kinda in a bind. I also tried RSView32 Works to log the info, but there isn't enough flexibility in logging. I need to log flow rate test results from a large automated machine. The mahcine does a number of operations, but we are most concerned with these four tags (since it conducts four tests at once). The problem is, the cycle time varies with the lot of product. Some products require more time as the process is more delicate. So, I can't use a time-interval logging method.
As for variable change, I can't do that either because it records the 4 test results in series; not all at the same time. That, and if the test is aborted (no tube), the previous test result value stays in the tag until there is a successful test.
I found a variable that changes once per cycle. I'd like to log the four tags once per cycle.
BUT I can't do anything until I get the I/O Wizard working.

Error -2147220733 occurred at DAQ Assistant (in Measurement and Automation Explorer)

Ok! Just before the weekend I figured out how to make channels in Measurement and Automation Explorer for inputs through a couple different NI input devices (USB-9211A & PCI-6229 DAQ). Things were going well. Loaded up the computer today, added a few more channels. Worked fine. Now all of a sudden, any channel I make has an error and if I try modifying existing channels and saving, I get same error:
"This global channel currently has an error. You can save the global channel, but it cannot be used until all errors have been fixed. Press "Yes" to save anyway, or "No" to cancel and show the error."
If I hit yes, the channel is non functional. After hitting no, I get:
"Error -2147220733 occurred at DAQ Assistant. Possible Reason(s): "
with no possible reasons listed. I tried restarting the program. I tried restarting the computer. I verified connections. Searched for the above stated error number on ni.com, google.ca, and in the MAX help files, and found absolutely nothing. I have no clue what to do. Any help would indeed be very much appreciated.

Hi there,
This is my first time on here and I've only been using this software for a couple of days so it's possible I'm making a trivial error but I thought I'd post here anyway as I can't find anything on the net about my problem.
I also get an error while trying to save:
Error -2147220733 occurred at DAQ Assistant
Possible Reason(s):
Requested Code: -2147220733
But mine comes about in different circumstances to the one in the original post on this thread by Kahless. I was editting a VI logger task and within that I was trying to edit an NI-DAQmx Task. I was trying to change the clock settings, specifically I was attempting to change the Rate (Hz) from the 1k default to just 20, or 200. I got the error while trying to save so changed it back to 1k, but the error persisted even though I'd set it back to what it was.
I thought at first it might be simply that I was trying to edit an NI-DAQmx task within VILogger, so I tried making the ammendment directly but the problem was still there.
Any ideas?
Many thanks.

Error 70025 in Measurement and Automation Explorer

After a clean reboot of the system I receive Error -70025 ("Return Buffer is not empty..") in the Measurement and Automation Explorer. When I click on "Clear RDB" which is supposed to solve the problem, it says "Error clearing the return data buffer". In the status tab, all LEDs are flashing (Error Code varying from 0xFFFF to 0x0182).
First, I simply tried to remove the motion controller (it's a NI PCI-7334) from the MAX tab which did not work. Then, I tried to repair the installation of all NI tools but this didn't help either.
I'm working with NI Motion 8.4 and MAX 5.4.0f0 on Windows XP.
Do you have any idea how to solve this problem? Currently, I cannot run the motor at all.
Thanks,
Jürgen
edit: I just realize that the controlller is listed as PXI-7334 in the Windows Device Manager but in fact it is a PCI-7334. Would this explain the problem?
update: Forcing the installation of the PCI-334 driver does not make any difference.

Hi Jürgen,
you can find the description of occurence and solution for this error here.
Please try it.
When it dosen't solve your issue please contact me again.

Measurement and Automation Explorer does not recognize two identical USB 3.0 cameras at once. How do I fix this?

I am running a set up which uses 2 identical USB Point Grey cameras of the same model (FL3-U3-13S2M-CS). Both USB cameras are plugged into the computer (blue USB cables).
When I open up Measurement and Automation Explorer and look under "NI-IMAQdx Devices" in the configuration tree, LavVIEW only recognizes one of the two USB cameras. Measurement and Automation Explorer only lists one camera, in which it recognizes it as "Point Grey Camera". Why this is occurring? How can I get LabVIEW to recognize two separate cameras of the same model?

That's about the old NI-IMAQ for USB cameras. IMAQdx has built in support for DirectShow connected cameras. IMAQdx should be able to use more than one DirectShow camera at the same time, but the Point Grey DirectShow driver may have some issues.

Impossible de simuler avec measurement and automation version 4.6

Bonjour,
quelqu'un saurait-i me dire pourquoi je ne vois pas apparaître "Periphériques NI-DAQmx" dans la l'arborescence "Périphériques et interfaces" de Measurement and automation explorer (4.6).
Est-ce des modules de LabVIEW (7.1) que j'aurais hommis d'installer (comme des drivers DAQmx, ou autres), est-cer la version de Measurement and automation explorer qui me créé ce problème ???
Je n'arrive pas à comprendre sachant que sur mon PC portable je n'ai aucun problème de ce type. (Il est vrai que sur mon portable, j'ai la version LabVIEW 8.5 et la version Measurement and automation explorer 4.3.
Bonne journée à vous tous
Edouard
Résolu !
Accéder à la solution.

Bonjour, as-tu installé le driver DAQmx ? tu peux verifier sous MAX -> Logiciels -> NI-DAQmx

Id like to be able to initialize my 7344 Motion Controller card from within Labview and not through motion and automation explorer

Every time I boot my PC , I have to reinitialize my 7344 through Motion and Automation Explorer in order for it to work. Does anyone have any suggestions as to how to initialize it from within labview itself?
thanks

Hi,
I am sending you a Vi for initializing the controller.The only thing you have to do is that you need to use sequence structure. In the first sequence you need to use the VI which is attached i.e 0 (default). Then the next sequence will be the program itself.
So that as soon as you run your vi the first thing done will be initialising controller using LabVIEW. Then your program will run.
Here the led in the front panel will glow green only the first time you are initializing.The next time it will be dim but no doubt your initializing will be taking place.Hope this vi solves your problem.

Problems with Measurement and Automation Explorer (MAX)

Hello LabVIEWers,
I have been having a serious problem getting MAX to start and to remain stable. Here are the specifics:I am running LabVIEW 8.5 Full Development System on a Dell PC with 1GB of RAM and plenty of hard drive space. The OS is XP Pro and I also have McAfee Enterprise Virus Scan software. MAX will start-up and appear to run for a few minutes and then the software bombs out. I get a "Measurement and Automation Explorer has encountered a problem and has to close" pop-up message. To fix the problem, I have uninstalled all NI software using MSI Blast. I have wiped the registry clean of NI keys as per instructions in previous posts. I have deleted any remaining NI software on teh hard drive including C:\program files\national instruments and C:\Documents and Settings\All Users\Application Data\National Instruments. I have then restarted the machine and did a complete fresh install from CD's, DVD's, and the harddrive (CD's written to hardrive and DVD written to harddrive first). I installed first the LabVIEW and then I installed the Device Drivers. I restarted the machine between installs. I have even installed the updated NIDAQ 8.6. After which I set protections on the NI directories to read/write. Ok, basically I have done all these things numerous times and I still cannot get things to work correctly.
I was able to get into MAX for a little while (it is somewhat stable immediately after a fresh reinstall). I defined 4 Simulated DAQmx devices and none of them acted like they were simulated. I received various errors saying that the device was not found or could not be started. So I basically could not run my software with the simulated devices. LabVIEW sometimes seems to work ok but just now, I got a "Error loading nidmm_32.dll, initialization routine failed" error. I also get the same error for nilvaiu.dll. Both of these DLLs are in the C:\Program Files\IVI\Bin and c:\windows\system32 directories respectively and prior to the last time I started the software, all worked ok with LabVIEW.
Is my computer failing? Are there any other options to getting this installed without probems?
Please help.

Parallel port not detected in measurement and automation explorer

I have installed labview 2010 in windows XP.
The problem what I am facing is I could not find "Serial & Parallel port" option in Measurement and automation explorer.
After seeing the similar problem in forum I have installed Ni-Daqmx 9.0.2. But still I can not see the ports in MAX.
I think i have attached enough document .
If the parallel port is not detected in MAX can we send digital data to parallel port.
I have tested parallel port with LED connecting one leg in 1st data line(pin 2) and another in gnd(pin 25).
And my program is to blink the led for every one second but I cannot see the blinking.
Can anyone help in this regards
thank you

I can't find my PCI card using Measurement and Automation Explorer

I've installed the PCI card.. It's a PCI-DAS08. The PC I'm running is quite slow, took like an hour to install Labview. The Measurement and Automation Explorer can't seem to find the card even though it's shown in the Device Manager. I don't know how to solve this problem. Any help or tips appreciated. THANKS

Is tha device made by NI?
MAX only supports NI DAQ devices.
You will need the drivers and support software from the equipment manufactuer.
