Accessing DAQ-Card 1200 in LabVIEW?

I configured Daq-Card 1200 in MAX, set the input and output values and so on. How can I now access the card in LabVIEW. Should there be maid any additional configuring under LabVIEW since first time I set up in and out values in MAX there was a place I could set different values to different channels but this time the configuration window lacked many things it used to have.

When you configure the device in MAX, MAX assigns Device Number to the DAQ Cards starting with 1.
In labview you can open up DAQ example and run it by specifying correct device number and channel number from which you want to acquire data. You do not need special configuration in labview.
Hope this helps

How do I use two DAQ cards in one Labview code? Current I'm getting error " error 200558 occurred at DAQmx Create Channel.vi. One task cann't contain multiple independent devices". Can someone help me?

The two DAQ cards are NI PCI-6070E & NI PCI-6052E. The Labview I'm using is labview 7 Express and the Window system is Window XP. I'm using NI SCXI-1000 chasis and SCXI-1102 & 1102B two modules plus a feedthrough SCXI-1180. 1102 is connected through SCXI-1349 cable to DAQ card 6052E while 1102B is connected through SCXI-1349 cable to DAQ card 6070E. SCXI-1180 is connected to 6070E through SCXI-1349 adaptor on the back of 1102B.

Sarah, thank you for replying my question. It seems that I'm making progress everyday (smile). I'm able to run the test using both daq cards in my code now. But as I'm moving forward, I'm getting new questions too. How do I use one STOP button to control both tasks and how can I save data into one single file?
I attached my code here hoping you can get the specifics on my application by looking at the code. Thanks very much!
Thanks.

Can I use a DAQ PCI-1200 with Labview 5.0.1?

I have a Labview 5.0.1 software, and I want to use PCI-1200 with it. Can I do that? My OS is Windows XP, but I can change it with Windows98/2000.

Hello jhylee,
The latest NI-DAQ driver for the PCI-1200 is 6.9.3, which is compatible with LabVIEW 5.0.1. LabVIEW 5.0.1 supports Windows 2000, but not Windows XP (although it may still run).
Have a nice day!

How to avoid dependance between output digital port with a PCI 1200 daq card?

Hello,
I don't manage to fix the state of a line on one port (PA0 for ex) without change the state of another line of another digital port (PB0 for ex)
I use a PCI 1200 Daq card with Labview 5.0.1 (under Windows 98)
How to configure a robust state (high logic level) on a line of a port??
Does anybody have an idea on this problem?
Thanks a lot in advance and happy new year to the community

Hello,
I've found the problem
The PCI1200 has a chip 8255 for Digital I/O
If I use the bad VI, it reconfigures the port and all the lines go in a low logic state
so I'd to write only on the port or the line without reconfigure the port
So the good VI in the palett is: Port Write and not Digital Port write!
See attached file..
Thanks
Best Regards

Method for accessing multiple DAQ cards

Hello, I am trying to access two analog-input cards in a "ping-pong" type fashion with LabVIEW 7.1.
The two cards are PCI-6052E DAQ cards (call them "B" and "C"). What I'd like to do, is get data in this fashion: B/ai0, C/ai1, B/ai2, C/ai3, B/ai4 ..... etc. However when I try to do this I get this error :
"Error -200558 occurred at DAQmx Create Channel (AI-Voltage-Basic).vi.
Possible reason(s):
One task cannot contain multiple independent devices.
Create one task for each independent device.
Device: B
Device: C"
So my question is, IS there a viable way to do this? I have attached my .vi that contains the trouble. Any help would be GREATLY appreciated! Thanks!

One task cannot span multiple devices. Your problem is that your physical channels in DAQmx Create Channel reference two different devices. You cannot create tasks like that. If you want to ping pong between devices, you'll have to do it with single point reads like this:
B/ai0 >> DAQmx Read Single Channel Single Sample
C/ai1 >> DAQmx Read Single Channel Single Sample
etc...
Hope this helps.

Looking for examples of VI with two or more inputs for the 1200 daq-card ( PCMCIA )

Thank you , if you can help me by sending VI examples for the 1200 daq-card
, with 2 or mores inputs

You can find several examples that will work with the DAQCard-1200 at zone.ni.com/libraries/.
Then look under Data Acquisition. There are also examples that ship with
LV and NIDAQ. Look in ...\Labview\examples\daq\anlogin\.

I use labview 8.0 and i can not run daqmx driver for pcmcia 6062e daq card

i use labview 8.0 on window xp .when i installed a PCMCIA daq card 6062E, i could not run daqmx driver.It is fine to see that the traditional version is working well.When i install daq card sometimes it is working well with traditional driver but mostly i see error on reading an analog input from PCMCIA daq device.An error called 'base adress' occures .I use last version of driver that is daqmx 8.0.1. and i have installed this correctly but again i could not see any signal on the test panel for daq-mx driver.I don't know what is the problem.Also when i install PCMCIA daq card Please reply this message.I need your helps.
Thanks

Hello,
Thanks for your reply.I will try to answer your questions.
I have checked the Device Mananger and I have seen that the device is detected by Windows XP. For another question the card shows up under both NI-DAQmx Devices and Traditional NI-DAQ (Legacy) Devices consistently in the Measurement & Automation Explorer.I use a way that I reset the driver for traditional NI-DAQ in MAX,and then i reset the device for NI-DAQmx driver in MAX and again i tried to run the test panel of DAQmx driver but again i saw a wrong signal or noise signal on the test panel i could not see the sinusoidal signal that i connected. i do get the test panels to run with the card using the DAQmx driver, But could not run the DAQ diagnostic utility.The error was as i specified below.

How can I create software start and stop trigger in LabView using 6023E series DAQ card? I don't want to use the external trigger.

I am using 6023E DAQ card to collect the signals, such as AE, Force, Torque from the machine. I want to collect only some part of signal for example between start triger and stop trigger. I'd like to know how I can creat those triggers in LabView from one of the channels that I am acquiring at the same time. I found one or two library file that is only for start trigger. I know that this is availabe in some of DIAdem functions. Please let me know if you have done some example for this requirement.

If you are wanting to create a software trigger based on an analog input voltage in LabVIEW, there are several options. One suggestion would be to compare the voltage values from one input channel to a number within a loop. If the input voltage crosses that threshold (is greater than the number), have a case statement that will acquire data from the other channels. This would simulate a software start trigger in LabVIEW.

Need an enable/disable Labview VI for SC-2062 relay board using PCI-6503 DAQ Card.

I am using Labview 6i, and I need to write an enable/disable VI that will enable and disable 6 of the 8 relays at any time while keeping the whole vi running. Therefore one or more positions may be changed at a time, but positions that don't change cannot be interrupted when changing others (no port resets allowed). I was wanting to maybe send a 1 by 6 array of some sort out but I can't figure out how to use the array to communicate with the DAQ card, relay board and SC-2051 adaptor. There also needs to be error handling in and out. Thanks for your help. Any examples would be very helpful.

Hello;
The best way to go about that is to disable the data points correspondent to the channels you want to disable. Meaning that you can ignore the datapoints of the channels you want to disable on the fly. That is the only way to disable channels on the fly.

How to arm channel 1 of a PCI 6133 DAQ card using labview?

Hi,
I am new to the Labview and I need some help. I have a PCI 6133 multifunction DAQ card and I'm using Labview 8.2 to capture five channels waveform data. I setup channel ai0 to be the trigger channel and I need to capture data from ai0, ai1, ai2, ai3, and ai4 when ai0 is trigger.
Question:
1) I am using DAQ assistant to configure my channels. How can I arm the channel ai0? I have an "execute button" and it should arm the scope when I click it.
2) Is there trigger ready signal, so I can save all the channels data when channel ai0 is trigger?
Can anyone provide some help?
Thanks

Hello wirte spreedsheet,
Thanks for posting to Discussion Forum. It looks like you are using the
PCI-6133 to acquire analog data from ai0:ai4. You want to use ai0 as
the trigger for the other channels.
Does your application need to be retriggerable?
Are you doing continuous acquisition?
Are you doing Analog start trigger or reference trigger?
Take a look the following shipping examples, found in LabVIEW click
Help>>Find Examples. On the browse tab, Hardware Input and
Output>>DAQmx>>Analog Measurements>>Voltage:
Cont Acq&Graph Voltage - Analog SW Trigger.vi
>> This example demonstrates how to perform an analog software
triggered acquisition. The example allows the user to specify the
triggering condition and the number of pre-trigger samples to acquire.
Cont Acq&Graph Voltage - Int Clk - Analog Start.vi
>> This example demonstrates how to continuously acquire data
(Waveform) using the DAQ device's internal clock and an analog slope
start trigger.
Take a look at these applications and let me know if you have any questions or comments.
Have a good day.

Mac G4 crashes using continuous generation with PCI-1200 DAQ card

I've been trying to use a PCI-1200 DAQ card with a Mac G4 to create a continuous analog output signal. The problem is that the computer locks up after a while (a few minutes). I have been using the Generate Continuous Sine Wave vi, but the problem remains.
I've tried slow signals (10Hz) and fast signals (2kHz) but the computer still seems to crash. I have no clue what is going on!

bissdp,
The first thing I would recommend is making sure you have the latest version of the driver:
www.ni.com > Support > Drivers and Updates > Current Versions > Multifunction DAQ
Another you could try is to determine what component is causing the computer to lock up. Use a process explorer utility to try to see what processes are locked up. A search in google might turn up utilities like this one: (http://www.clarkwoodsoftware.com/peekaboo/)
Keep in mind heat or speed issues. It may sound funny, but you may want to try opening the computer case and making sure the board has enough air flow to keep it cool.
These are just some ideas for now, I hope they help.

Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)?

Hi all,
Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)? if yes then how? please give brief idea.
Regards,
Amit

There is probably a way to do it, but it it may be easier to use an X-series board for the job. They support a new counter capability for count reset on a digital edge without needing to be configured in encoder position mode. I am not sure exactly how that feature's been implemented however, so maybe it won't make things easier after all.
The plan based on the hoped-for behavior:
1. Configure an X-series counter for pulse generation based on "ticks" of your clock channel.
2. Set both initial delay and low time to the critical # of ticks.
3. Configure for count reset on a digital edge (if possible in pulse generation mode)
4. Configure the count reset value to be the critical # (or possibly 1 less, if possible in pulse generation mode)
5. If you want the output to remain high indefinitely, configure the counter task to use its own output as a
pause trigger, and pause while high.
The way pulse generation works is to preload a # of "low time" ticks into the count register. Then every source edge will decrement the count. When the count reaches terminal count (0), the counter's output is toggled (or can be configured to pulse). The register is then loaded with the # of "high time" ticks and the process continues.
You would be perpetually interrupting the count-down process as long as you got your triggers in time. The count would keep getting reset to the # of low counts, keep decrementing toward 0 without reaching it, and so on. If ever you did reach 0, the output state would toggle high, then the high state would prevent subsequent clock signals from decrementing the count.
You can conceivably do a similar thing with a 6601, but I'm pretty sure you'd need 2 counters working together to get it working.

How access to Smart Card Readers using Labview?

I´am trying access to Smart Card Readers by Labview, but I have problems.
I want to read SIM card GSM using Labview.!
The file winscard.dll has the functions to access, but I dont have skill with "Using External codes in LabView".
In MSDN library there is the specification about the functions for winscard.dll
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthn/security/smart_card_authentication.asp
When you install a driver for some smart card reader you access to it by winscard.dll.
Att. Enrique

Finally I can acces to the smart card readers (PC/SC) with Labview,   this is the first part where I can establish the context and realease it, and I can get the first name of my list of PC/SC readers that I have connected to my computer.
I was wearing the "Call Library Function" for winscard.dll
For Establish the context you need :
    function name : SCardEstablishContext
Calling conventions : stdcall (WINAPI)
function prototype :    long SCardEstablishContext(long SCARD_SCOPE_USER, long NULL1, long NULL2, unsigned long *hContextHandle);
function name : SCardReleaseContext
Calling conventions : stdcall (WINAPI)
function prototype :  void SCardReleaseContext(unsigned long hContextHandle);

Installing labview before DAQ card?

Hi,
We've just bought LabView 8.2 and a new DAQ card, PCI 6281 M series...
What I was wondering was whether there is any order in which these need to be installed. At the moment there is no pre-existing version of LabView or DAQ Software on the computer.
I have just read that the drivers that came with the DAQ card need to be installed before the card is inserted into the PC, but am not sure if LabView is supposed to be installed before or after the card or if it even makes any difference.
Thanks,
Harry

Thanks!!
