PCI 7830R series DAQ card with SCB 68

Can anybody how to mapp PCI 7830R card with SCB68, which was connected in 0 connector? is thier any VI as an example for this

Hello Sir.... i created a VI in Project Explorer Methode to test the working condition of DAQ card PCI 7830R which i installed in my PC , in both Sub VI and the Host VI the programme is working , now i connect the SCB 68 hardware with DAQ card thro RMIO cable , i wired the DIgital Pins of SCB68 (respectievely with DAQ card Pins) in a Bread Board an place a LED corresponding to pins to show the real world output...
Now my prob is after i connecting the wire i run the VI, in breadboard the LED's are not getting ON same status is displayed in Labview Front panel too , when i remove the wire the LED in front panel of both sub and Host VI is getting ON..... y this prob occuring? to solve this what i have to do? i want to show realworld output (LED On in Bread board) thro SCB68... how to solve this?

Which type of ADC is used in M Series, S Series and C Series DAQ Cards?

Hi
I want to know which type of Analog to digital converters(ADC) are used in M Series and S Series DAQ Cards. I know that DSA Cards and some C series are using Delta Sigma ADC. What about the ADC used in non delta sigma C Series modules. Why Delta sigma ADC is not used in M series and S series DAQ cards.
Regards
Samuel J

Hi Samuel.
The ADC type used is Succesive Approximation ADC. You can refer to the following links for your reference.

How do I read the FIFO correctly on an M series DAQ card?

I have a PCI-6229, which I have working with the exception of a bug or two. The program continuously reads multiple inputs from the FIFO buffer, which is being filled at around 100 kHz. Every ms or so, the program reads all the values in the FIFO. To keep track of the input channel being read, the program currently indexes a channel variable every time it reads a value from the FIFO and continues until the FIFO is empty. The next time it starts reading the FIFO it continues from the last input channel read. This works correctly sometimes, but other times the tracking system gets off by one then associates the values with the wrong input channels.
As an example, reading two inputs at 100 kHz the DAQ card appears to read one input every 5 microseconds and put that value in the FIFO. When the program reads, sometimes it reads an even number of values and other times an odd number. The program tries to keep track of this, but several unmonitored variables that I'm aware of and several that I'm probably not aware of can lead to my tracking error. The FIFO filling up is one example, I believe. Many times when the card is started it is already off by one.
Is there a way to know what input a value in the FIFO is associated with? I'm trying to have the DAQ card run continously, empty the FIFO periodically, process the data, and continue this process. I don't want to start the AI task for 1 ms, read the values, process the data, and restart the AI task for 1 ms if I don't have to. Thanks.

You could try using DMA. This thread has a code example and some corrections. I did not have to delete the acdReset, but your mileage may vary.
Good luck

Is there anybody who has interface NI DAQ card with Pressure System Scanners

I am trying to acquire data from Pressure System's sensor ESP 16 BP with NI DAQ card PCI-6221.
Is there anybody who has perform this job.
Thanks,

Hello Surender.
Thank you for contacting National Instruments.
Although I have never used that particular pressure sensor, the setup for measuring a pressure sensor is usually the same. Since the sensor probably outputs a voltage that is correlated with the amount of pressure that the sensor is detecting, we can configure a voltage task inside of Measurement and Automation Explorer and then port that into LabVIEW. A great video tutorial of a DAQmx task being created and then transferred into LabVIEW is available at:
Creating a Task in NI-DAQmx and Using it in LabVIEW
http://zone.ni.com/devzone/cda/tut/p/id/5374#toc2
Also, there is a great site that contains general information on pressure sensors at:
Measuring Pressure with Pressure Sensors

Let me know if this information answers your questions. If you have a more specific question, please let us know and we would be happy to help you.

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.

Frequency counter with E-Series DAQ Card

I am trying to measure the frequency of a signal at 0.1 sec increments using a DAQCard-6062E and an AT-MIO-16E-10. I am using a VI from the examples (frequency counter.vi, in a while loop) which works well with the DAQCard, but it's giving wrong measurements with the AT-MIO card. Why is that?

Hello Waw,
Take a look at this KnowledgeBase to see if it fixes the problem.
http://digital.ni.com/public.nsf/websearch/862567530005F09E8625681C0074935E?OpenDocument
If not, what version of NI-DAQ do you have? Are you getting incorrect measurements with different ranges of frequencies? Is LabVIEW giving you any errors? Do any examples provide correct results with the AT-MIO-16E-10? Please let me know if you have any questions. Have a great day!

How to recognize s-series daq card in DAQmx Base 2.0

I installed the "DAQmx BASE 2.0", and then installed 3 PCI DAQ boards. It can recognize PCI-6024E and PCI-6713, but not PCI-6133.
I followed exactly the same procedure as in the document called "How do I use NI-DAQmx Base with PCI/PXI Devices on Windows?"
http://digital.ni.com/public.nsf/websearch/9C4E9FD0C7469BC286256F100074EADC?OpenDocument
However, there is a web page (the link below) having labview example programs using DAQmx Base for "NI 6110 S Series Multifunction DAQ". So I think probably there is a way to recognize the S-series devices in DAQmx base.
http://digital.ni.com/public.nsf/allkb/722DDAB4E914073D8625708100773677
Does anybody know how to recognize S-series device in DAQmx Base 2.0?
Thanks

Alan,
Thank you very much for the quick response.
The reason I explored DAQmx: I want to do RLP and DAQmx Base has a simpler interface and more examples for RLP.
The reason I want to go RLP instead of DAQmx is a long story.
Summary of my applications:
I need to read 4 input voltage (using PCI-6133) and then generate 12 voltages (using two PCI-6713 each has 8 outputs). Since the 12 generated voltages are related to the 4 input voltages, single sample /N channel AD/DA is required. The speed for the overall control loop has to be >100 kHz.
Summary of my configurations:
PIII, 700 MHz CPU, 512 MB RAM
PCI-6133 and PCI 6713, LabVIEW 7.0, and DAQmx 8.0
I also have PCI-6110 and PCI-6024E cards for comparison
Summary for 4 channel single point acquisition (See the table below, AD only)
1) The difference between P3/700MHz computer and P4/3GHz computer is very small
2) The S-series performed worse than E- and M- Series
     Spec (kS/s)   Tested by me(700MHz P3)   by NI engineer (3GHz P4)
6024E   200/4            15.7 kHz                    17.36 kHz
6040E   250/4                                        18.9 kHz
6251   1000/4                                        23.0 kHz
6133   2500/1            13.8 kHz
Summary for single channel single point acquisition (See the table below, AD only)
1) The S-series performed much worse than E- and M- Series (simultaneous sampling is worse?)
     Spec (kS/s)    Tested by me (700MHz P3)
6024E    200/1           54.8 kHz
6110    5000/1           19.4 kHz
6133    2500/1           14.5 kHz
Simulated device          135 kHz
Summary for single channel single point AO (See the table below, DA only)
The spec of 6024E is only 10kS/s, but the loop can run at 132 kHz (the output from the port was not correct for sure). Using a simulated device (either 6024E or 6713), the loop rate is ~ 134 kHz (probably due to my low speed computer). This means the latency from 6024E devices is virtually zero. However, the latency from 6713 is way too much.
      Spec (kS/s)   tested by me (700MHz P3)
6024E    10/1             132 kHz
6713   1000/1              38 kHz
Simulated device          134 kHz
From all the above tests, it seems that s-series device (6133) and AO device (6713) perform much poorly in single point mode compared to E-series device (6024E). I thought the difference might be due to the driver in DAQmx. So, I want to try RLP to see whether I can gain up control loop speed to 100 kHz for my applications.
Your suggestions and advices are appreciated.
Thanks

Multiple S series DAQ card

Hi,
i will use multiple S series card (PCI 6143). I want to thread them as one card (by connecting them with RTS cables).
How can i program them? I can't find any example about this
Thanx

Hi eesen-
I'm assuming that you'll most likely want to share a sample clock and/or AI start trigger between the two devices over RTSI. In order to do this you will need to first export the appropriate signal from the 'master' device, like this:
theSTC->RTSI_Trig_A_Output.writeRTSI_Trig_2_Output_Select(trigSelect);
// Set output select first, then route to RTSI to avoid glitching
theSTC->RTSI_Trig_Direction.writeRTSI_Trig_2_Pin_Dir(1); // 0=input, 1=output
where RTSI_Trig_n refers to any of the RTSI trigger lines <0..6>. Valid values for trigSelect are outlined on page 388 of the DAQ-STC Technical Reference manual.
On the 'slave' device you will then want to import the signals from RTSI. For the ai/SampleClock, you'll need to make this change to the aiSampleStart() function (or just call this method with the appropriate setting):
theSTC->AI_START_STOP_Select.setAI_START_Select(trigSelect);
theSTC->AI_START_STOP_Select.setAI_START_Polarity(tSTC::tAI_START_STOP_Select::kAI_START_PolarityRising_Edge);
where AI_START refers to the ai/SampleClock signal that clocks each sample from the input ADC's. Valid values for trigSelect are shown in the tSTC.h ChipObject file in the tAI_START_STOP_Select::tAI_START_Select enum.
For the ai/StartTrigger on the 'slave' device, you need to change this setting similarly as before (as shown from aiTrigger() in the DDK examples):
theSTC->AI_Trigger_Select.setAI_START1_Select(trigSelect);
theSTC->AI_Trigger_Select.setAI_START1_Polarity(tSTC::tAI_Trigger_Select::kAI_START1_PolarityRising_Edge);
Hopefully this helps-

No ISA slot available in PC. How can I use PCI-85 Modbus Plus card with Lookout?

My application is to communicate with two Modicon PLCs using Modicon's ModBus Plus (PCI based PCI-85) network card inside my PC, and using Lookout as an SCADA software. Since there is no ISA slot available in new PCs, I can not use Modicon's ISA-85 Modbus Plus networc card. But Lookout does not support PCI based PCI-85 card, how can I use PCI-85 card then, with Lookout? Why doesn't Lookout support it? I asked the following question from from the Modicon's representative about it:
If I purchase Modbus Plus Driver Suite CD (SWMXDS001, 05, or 10 etc),will I be able to use Lookout SCADA software (by the way, it supports standard MB+ prtocol) for my application? If yes, can I use any version of an
y of the ISA, PCI, or PCMCIA based MB+ card?
His answer was:
The Modbus Plus Driver Suite will talk to any version of card, PCMCIA, ISA, and PCI. The question now is will the SCADA package you are
planning on using be able to talk to the Modbus Plus Driver Suite? You must contact National Instruments and ask them if they support Modbus Plus, and if
they used the MB+ system developement kit to develop their product. Or if they wrote their own MB+ drivers, do they work with Modicon hardware?

Hi,
currently Lookout does not support the PCI-85 card. The only card supported for Modbus Plus is SA-85. Please see for further information:
Where can I Find Drivers for Communicating to PLCs, RTUs, and Other Industrial Hardware?
How to configure the SA-85 card for Modbus Plus

Using LabVIEW and an E-Series DAQ Card to perform relatively high speed single point acquisition in response to a changing DIO pattern.

I am using the DIO lines on my E-series card to drive an external multiplexer which switches 1 of 8 sets of 3 signals to channels 0,1 and 2 on my DAQ. I need to acquire the 3 single points of data, do a little processing, then update the mux code before acquiring the next 3 points of data and so on. I have been trying to do this using hardware controlled loops but can only achieve a real sampling rate (time between the same set of three signals) of about 200s/s. I am trying to achieve in excess of 800 s/s. Any ideas?.

HI CP,
You are doing pretty good if you are getting 200S/s.
I believe the only way you can get 800 S/s reliably is to go to LV-Real Time. Not for the speed, but for the determinism.
That's my idea.

Can i generate PWM output from digital out of my PCI 7041 RT DAQ card?

I want to generate 4 PWMs using my PCI7041 card. I do have only 2 analog outputs and 2 counters to output my signal that's why I want to use digital out of my card for PWM. How can I do that? If there is any example then please let me guide that way.

Hello rajen,
There is a good link to PWM in LabVIEW using counters here.
As for using analog output, you will need to be able to continuously update your output waveform. I've attached a program that demonstrates this. Hope this info is helpful.

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?

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

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.

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.
