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 !

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

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

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.

GPIB non reconnu par Measurement and Automation

Bonjour,
J'ai installe une carte "GPIB-PCI 12.002 (AMCC)" sur ma machine qui tourne sous Windows 2000.
Windows reconnait parfaitement le peripherique et pour lui la carte fonctionne correctement.
Cependant dans l'explorateur "Measurement and Automation" de labVIEW la carte n'apparait pas du tout.
(meme en actualisant l'explorateur plusieurs fois, la carte n'apparait pas).
Merci de bien vouloir m'aider.

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".

Measurement and Automation looses its way

If I open Measurement and Automation while my Labview Application (executable) is running, Data Neighborhood comes up empty. Although my application continues to run OK. If I repoint (set active) MAX and relaunch my application I get multiple errors (can't find channels). Reinstalling Ni-Daq 6.9.1 did not solve the problem. Version - Labview 6i, MAX 2.1.

Hello;
That is happening because both the Labview application and MAX are trying to access the same dll, which is nidaq32.dll. As that dll is not a multithread dll, if more than one application tries to access the same resource, some errors may occur.
Hope this helps.

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.

Complete hardware simulation using LabView, Multisim, and MAX (easy answer accepted!)

Hello, all!
Sorry, I'm new, but I've checked around for a definitive answer on this, but I'm not 100% sure. I'm learning LabView for an upper-division Physics class. We're using NI hardware (DAQ-MX) and a mix of lab hardware - primarily basic stuff such as voltmeters, oscilloscopes, and breadboards with simple components. I'm also doing some work with NIM instrumentation, but that's secondary to my needs here. So, when I'm away from school, is it possible to do a complete simulation of my classwork using LabView, Multisim (for my breadboard), and the Measure and Automation Explorer (for the DAQ-MX)? I know that I can create a circuit and drop it into Labview, but I'm not so sure about the DAQ. I'm hoping for something that's a "seamless" recreation of what I'm doing in class. I can take a simple "yes" or "no"; as long as I know that it's possible, I can look for the solution.
Thanks for the help!

I have an easy answer and a harder answer:
Easy Answer
You can simulate almost any NI instrument in MAX. Right click the Devices and Interfaces item in the left pane and select Create New... Unfortunately, this limits you to whatever the driver designer thought would be a good signal. It is good for simple testing, but you will rapidly run into its limitations.
Harder Answer
Use LabVIEW classes to make a hardware abstraction layer. This my seem like an advanced topic for a beginning LabVIEW programmer, and it is, but it also neatly solves the problem of switching between simulation VIs and real acquisition VIs without writing a bunch of switching code. In short, you create a LabVIEW class which has the interface you want for you data acquisition. This can be your simulation code. You then create a child class which has exactly the same interface, but uses the DAQmx/NI-SCOPE/NI-DMM/etc. that you really want to use. Switching between the two is as simple as selection the class you want to use at run time. This is a lot of info in a short time. If you want to go this route, read the LabVIEW help on LabVIEW classes and work through the examples. I would encourage you to do this, since the sooner you learn how to effectively use object-oriented LabVIEW, the easier your life will be.
As a further bit of information, most of the measurement instrument groups (e.g. NI-SCOPE, NI-FGEN, NI-DMM, etc.) allow you to simulate an instrument if you use the open with options VI instead of the standard open VI. The inputs are rather arcane, but get the job done.
Let us know if you have further questions.

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.

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?

Applescript and automator

I have studyed html for 3 days and wordpress for 3 days , word , excel for 5 days, and llustrator and photoshop 13 yeas ago for 6 months.
and still now its so hard to understand some how.
but I am in need of understading now with the printed documents from my computer.
and I wonder , so there are many defferent way to communicate with anyone out side of the world, right?
like I know email , fax, facetime,
but there are other way now I think because of the documents I found.
and also with applescript and automator can do anything possible like even the child can click one and start conecting etc..
I have the copy from its ,
does anyone have time to explain me what it is?
It's not that of teenager who doesn't want paretns to know or else,
but I am quite serious for my situations.
Please Help !

Using JavaScript to script System Events wouldn't be any better, since it uses the same Apple Events mechanism (how well it uses it is another topic). To hold down a key you would need to use something that has access to the deeper system APIs, most likely using Xcode.
And yes, your code snippet will press the arrow key 5 times (I am guessing that the missing space in key code is a typo). You can place the cursor in a bunch of text in another application such as TextEdit, and use your script to activate it before performing the key codes to get a better idea of what is happening (trying to reposition the cursor in the Script Editor will reveal a bug with the delay command).

Whats a good mac to use for a home flight simulator with flight controls and foot pedals?

whats a good mac to use for a home flight simulator with flight controls and foot pedals?
My old 6100 AV worked great on A10 ATTACK, back in 1993.
whats a good set up now a days?
I havent seen any MAC set ups as a lot of the after market accessories are on Windows platform.
Is there a way or should I get a dedicated simulator on PC?

The fact that USB flight input devices appear to Windows only is not a limitation; for Mac most are programmed through the sim itself. I know X-Plane does that.
I've simmed a lot and know that good sims need a lot of processor and video hardware horsepower, and you'll also need a lot of RAM. They also run up the internal temps. A Mac Pro has better cooling than an iMac. You can get a program like SMCFanControl to manually set up the fans speeds before starting the sim.
I know of no sims today that will still run on a PowerPC Mac (2005 and earlier) so you need to look to an Intel Mac with top specs. If looking at iMacs, start by looking for the quad-core i7 processor. Those models usually came with an up-rated video card. Thing 12 to 16GB RAM.
My 2010 iMac has the 2.93gHz i7 processor, video hardware (ATI 5750) with 1TB VRAM, and 12 GB of RAM. It runs the x-Plane 10 demo fine but I've not bought the full version because v10 seems to make foot pedals darned near mandatory, and I don't want $100 worth of pedals under my regular work desk at the moment.

OPC custome and automation I/F

Hi all,
Sure it's clear I'm just a beginner in OPC. I wanna know what are OPC custom and automation interfaces?
Thanks...

Hi,
for connecting to OPC, you can simply use Datasocket. If you're designing a larger system, then you might want to have a look at LabVIEW Datalogging and Supervisory Control, which prior to LabVIEW 8.0 runs with a tag engine to connect to the various external data sources, including OPC, and then you write your code to talk to the tag engine. To learn more about LabVIEW 8.0 and the DSC module have a look at the links from here : http://zone.ni.com/devzone/conceptd.nsf/webmain/D76C3788A0C4C5668625708B0072987C
Here's the link to a search results page that will allow you to find out more about Datasocket and OPC connections.
http://search.ni.com/nisearch/nisearchservlet?nistype=default&ddown=0&filter=%2Btaxonomy:top+%2B(met...
(from ni.com, top right hand corner and type in "OPC datasocket" (without the quotes)

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.
