Labview DAQ channel wizard

I followed instructions in the Labview manual to access the DAQ channel wizard. For some reason I am directed to the device & automation explorer instead. I have Labview 5.1 installed on windows 95 system.

Hello;
You are probably being pointed to Measurement and Automation Explorer to have your hardware configured.
MAX is the Software that allows you to configure your hardware and set some virtual channels up.

Labview DAQ channel viewer doesn´t view to much

Hi, heeelp please
I´m starting to bealive in goblins.
I have a Pci-6013, and did a university proyect using also NiDAQ 6.9.3 and Labview 6.1 eval. I tried mi code in a modern amd 2600 pc and worked fine.
Then i installed it in a Shuttle SKG1, for the cybernetic fountain (my proyect, a photo is attached, working, with the old good new computer, by the Shuttle, almost not to be seen) to be more nice. But i couldn´t get it to work, since the simple Write to digital line.vi wouldn´t get to work; LabView doesn´t read the channels i had previously configurated in the MAX explorer. When i go to tools, Data Acquisition, Daq Channel Viewer i get to see other channels i didnt configurate, like sine, or temperature.
In the Amd 2600 normal computer the problem doesn´t arise, when i go to the Channel Viewer i get to see my channels. Well, i´m in troube, since i need it to work eather in the Shuttle or in an old Pentium II, in which the same probem arises. What do have a Shuttel and a Pentium II old computer (eaven with Isa slots, besides the Pci slots) in common against a normal Amd 2600 in an Asus board in common for it to do such a thing.
Any hinch on the topic would be by this time very much apreciated.

It is not really clear where you see what in MAX.
If you have developed and tested your program and configured the channels on the AMD PC you have to do the following:
Open MAX, select File>>Export and go through the wizard to export the NI-DAQ configuration. You will get a file. Copy this file to the target machine. There open MAX and select File>>Import. Select the file you have copied. Then you should see your channels in MAX and your application should work.

Configuring DAQ channels through LabView program

Hi,
I want to scan one analog input of PCI 6025E every 250 msec and I scan 8 such channels. I am using AI Sample Channel VI to do this and for its channel input I am feeding a string (with channel name) that is typecasted using a Traditional DAQ channel constant. All the required channels are configured using this constant. However this VI doesn't seem to be portable. When I use it on a different machine, the constant shows no channels defined.
Is there a way to configure DAQ channels through my program such as to make the program portable? I came across notes that mentioned DAQ global channel but I don't know how to use it.
Thank you in advance,
Sharmila

One of the great things about DAQmx is that there are only 4 basic VI's to learn to use. The Configure, Read, Write and Stop. The same Configure VI that was used to setup the analog input channels can be used to setup analog output, digital in/out and counter in/out.
The small menu on the bottom of the VI is actually a listing of all the different operations that this single polymorphic VI can do. Click on the down arrow and you'll see what I mean.
I've modified the example to read DIO lines 0-3 and write to lines 4-7 on Port 0. Again it programatically builds the channel list so it will always refer to the correct device. To create individual channels for a digital line, you first specify the device, then the port, then the line or lines. Example, to create a task for lines 4-7 on port 0, you would use "Dev1/port0/line4:7".
Notice that the "DAQmx Create Channel.vi" is the same one used in the analog input configuration, but with different polymorphic selections. Also note the "DAQmx Read.vi" is the same except for the selector.

DAQ Solution Wizard greyed out in Labview 5.1

My DAQ board seems to be work correctly when using MAX, but in LabView the DAQ Solutions Wizard is greyed out. I have a PCI-MIO-16E-4 DAQ board, Labview v5.1 and NI-DAQ v6.9.2f8. I am running Windows 2000.

Make sure that the LabVIEW 5.1 support files have been installed along with NI-DAQ. Go to the Control Panel >> Add/Remove Programs >> NI-DAQ >> click Change >> select Add/Remove. If there is a red X next to LabVIEW 5.1 support, then it has not been installed. Install the entire feature and the DAQ Solutions Wizard should work.

Why do i get a daq hardware configuration required window when trying to run the daq solution wizard?

i have recently installed the ni 4552 for pci dynamic signal analyser, and am attempting to configure my system and teach myself labview. when attempting to run the daq solution wizard i am presented with the daq hardware configuration required window.

hi brian, thanks for your help. i have recently received version 6.1, and done a complete re-install. i have also downloaded the latest ni daq (6.9.2) and ni dsa (6.11) versions and installed them, but still i get the same error message when trying to open the solutions wizard (please see attached powerpoint presentation).
upon selecting the "go to ni daq config utility" option MAX opens. everything appears to be in order (device passes test, test panels run ok and virtual channels are configured correctly). i am unable to go any further.
i would appreciate any guidance that you are able to give me in this matter. many thanks in advance of your help.

Setting DAQ channel by property node does not display the value

I am writing a configuration VI to set channel selection and calibration parameters for an SCXI chassis. I store a default setup in a configuration (ini) file and read that file automatically when the VI is called. The value from the file are set by property nodes using the "Value" property. The values from the file do not display in the DAQ channel selection rings, but the numerical calibration values do display correctly. When I click the down arrow in the channel rings, the correct value displays.
This behavior exists both in LabView and app-builder EXEs. Also, if I change the property nodes for the DAQ channels to local variables, it works. The Value (signaling) property doesn't cause them to display
properly either. Why can't I use the property node?

I don't understand exactly what you are trying to do.
Please upload a simple VI to demonstrate the behavior you are describing. Remember also to attach the .ini file.

Fastest way to read and write to/from muliple DAQ channels

I'm developing an application in which multiple DAQ channels will be monitored, for example, displacement, load, strain, temperature and so on. My question is what is the fastest and most efficent way to check the value of these inputs, compare them to user inputs and then decide whether or not to write a different voltage to an output. I'm using LV 7.1 on Win 2000.

I guess my first question would be are all these channels going to be on one card? Are you going to just make single measurements (are you interested in instantaneous values vs. "waveforms")? Doing a "Sample channels" for instance will make a single measurement of several channels (on the same board) and present you with an array of the resulting data, one element per channel. How fast do you need to sample, are all of the signals going to be on the same board? The latest NI-Daq allows configuring tasks that mix channel types (T'couples, straight voltage measurements, etc.) which makes configuring the DAQ easier.
If you can give us a little more information regarding what you are trying to accomplish it will help.

Ask for help with LabView Daq and Tek VX4244 VX4101

I use NI VIO-MXI-64XE-10, Tek VX4101 and Tek VX4244 to acquire data in one
Tek 1410A VXI mainframe connected a PII 350/64M computer with MXI2
cable.these modules are used for three independent applications,the datum
are acquired and through preliminary computation, then sent to three TCP/IP
ports the computer served in real time. the burden of the system will be
very heavy because the 64XE-10 need to use up the 100K sample rate
continuously dealed by 50 channels,and the VX4244 need about 30Hz for all 16
channels.
64XE-10 is easily detected by NI software, and I can use LabView Daq
intermediate analog input VIs to acquire data in background, read 50 samples
and compute the mean for each channel,then packa
ge the 50 mean and send to
client end with 40 times a second. I found the speed is satisfactory.
As for VX4244 and VX4101,I can't use LabView Daq VIs,and the driving
functions for LabView with the product are difficult to understand, I want
to know how I can get data and send out efficiently,how to get data in
background,and how to use FDC ?
And for 64XE-10, although the speed is satisfactory, but it use much more
CPU resource, I want to use advanced analog input VIs to build the code,I
want to know where I can find examples using the advanced analog input VIs ?
Best Regards

Get daq channel names

I recently upgraded from LabVIEW 6.i to LabVIEW 8.5. Back in 6.1 I could get all the channel names configured in MAX using Get DAQ Channel Names.vi. I was wondering how I can do this in 8.5. Ideally I would like the output to be an array of strings so I can then sort through them.
Thanks

Hello,
I think that you can do that on daqmx. Using property node. See the attached file.

DAQ channel name control empty

I'm having the problem that virtual channel names don't appear in DAQ channel name controls or constants. The proper channel type is selected, but nothing appears. I'm also missing a couple of contextual menu items on the control, such as add channel and edit channel. Any ideas?
I'm using MAX 3.0, DAQ 6.9.1f28, and Labview 6.0.3. A different system with MAX 2.1.3.14 works fine

MAX 3.0 ships with the NI-DAQ 7.0 driver. You should not be using MAX 3.0 with the older 6.9.1 driver. I would recommend using the MAX version which ships with the NI-DAQ 6.9.1 driver. If your working system is identical with respect to NI-DAQ and LabVIEW versions, then I would recommend using MAX 2.1 with the non-working system as well.

Daq channel name constant

Hello,
I'm using LABVIEW 6.1 on a computer that does not have a DAQ card
installed. I would like to create a listbox that allows selection of
multiple DAQ channels. My problem is that the AI Group Config.vi
requires a DAQ Channel IO data type which is neither a string nor an
Integer. I tried to use the DAQ channel name constant, however I
wasn't able to enter a value for the constant. This problem may be
caused by the DAQ card not being installed.
Therefore, my question is that if I had the DAQ card installed, would
the DAQ Channel Name Constant allow me to enter a value?
Thanks,
Steve

I believe you can at least type a name into the control/constant if you
right click on it and select "Allow Undefined Names". Then just double
click in the control and start typing.

Incorrect AMUX/PCI6025 readings using Labview/DAQ

I have an AMUX64/PCI6025. Using my DVM, I measure the voltage at the AMUX screw terminals on various channels with correct readings obtained. Performing measurements with Labview/DAQ are incorrect. What is causing this?

Hello;
The first thing to double check is if the input mode is set accordainly with the connections made.
The best bet is to revisit the AMUX Users Manual and double check the connections you made with the ones shown in the manual. Furthermore, go to MAX and check the input mode of the DAQ device.
Everything must match.
In case you got everything accordainly with the manual, and you still see the same behavior, the problem is probably hardware related.
Hope this helps.

How do I use "LabVIEW dll import wizard" to import NETAPI32.dll

I am trying to use the LabVIEW dll import wizard for the first time. I am not very familiar in C-coding so this might be a good help instead of configuring CallLibraryFunction nodes myself.
I want to import NETAPI.dll. I am interested in several functions in that dll, but my main priority is the funtion NetUserGetInfo(). On MSDN I have found that the header file for the mentioned function should be: lmaccess.h (include lm.h).
My problem is this:
The shared library contains 317 function(s). But no function is found and recognized in the header file. The following function(s) cannot be wrapped. If you want to import these functions, please review the warning messages next to the functions below. You will need to fix the problems before you can continue with the wizard.
The function cannot be imported into LabVIEW. This might be caused by one of the following problems:
The function is not declared in the header file but is exported in the library.
Check the header file to make sure it contains declarations of the function.
Undefined symbols can prevent the wizard from recognizing functions and parameters. To correct this problem, check the header file to determine if you must add predefined symbols. Click the Back button to return to the previous page of the wizard to add a predefined symbol (for example, "NIAPI_stdcall = __stdcall" or "NIAPIDefined = 1").

Any suggestions how I can solve my issue?

Desktop channel wizard failure

Hi,
I tried to create JSP channel using the Desktop Channel Wizard. But everytime i click on the "Finish" button, i can't successfully create the channel and it gives me the error message "Error: An error occurred while creating the channel. Consult the iwtAdmin debugging files for more information and seek technical assistance.". Same thing happens whenever i try to create JSP, URL Scrapper or Rich Site Summary channel.What would be the possible reason that cause this? After installing the portal successfully, i didn't change any setting and tried to create JSP channel using the wizard but it fails. Please help.

Its hard to say what could be the source of the problem without looking into the debug log files ..
Do the following the paste the log files
Login into the admin console
click on Manage Platform Setting and then administrator.
Select Enable Message Debugging and click submit.
Now go to platform.conf in /etc/opt/SUNWips and change ips.debug=message and restart the server.
Now do a tail -f /var/opt/SUNWips/debug/iwtAdmin log file and try to create the channel ..
Paste the error logs that you get when you try to create the channel ..

Hey Peter,
Ahh, I understand the graph now! Hmm, this is very strange behavior. Instead of using the DAQ Assistant, try to use the explicit DAQmx VIs (see picture). You have more explicit control over what is going on with the DAQmx VIs and keep as much as you can out of the loop.

Erik
