Quadrature encoder with PCI-6259 DAQ board (driver for QNX)

where can I find any example for connecting Quadrature Encoders with M Series DAQ Boards ?
The only more or less suitable example I found in nimseries DDK, is
"Count pulses from an external source using an external signal to control
the count direction" (nimseries\Examples\gpctex2.cpp).
But this example is not working correctly with Quadrature Encoders
(encoders with two shifted on 90 degrees phases A&B).
i.e. in case of using this example code I get some extra count while encoder is on vibrant motor
what means enums
typedef enum {
       kG0_Up_DownHardware          = 2,
       kG0_Up_DownHardware_Gate     = 3,
} tG0_Up_Down;
and
typedef enum {
       kG0_Encoder_Counting_ModeId          = 1,
} tId;
in (nimseries\ChipObjects\tTIO.h) ?
What initalization procedure I need to work with Quadrature Encoders?
I have PCI-6259 DAQ device
and I'm writing programm under QNX6 operating system

Hello alexey_3269,
If you want to read a quadrature encoder start with gpctex1.cpp and follow the thread.
I give you my code:

DAQ PCIe-6259 vs. PCI-6251

Should I buy a PCIe-6259 or PCI-6251 ? ( I think that PCIe-6251 is not delivered in the Netherlands)
Is the software for both cards the same?
What slot do I need with PCIe-6259 in my motherboard, PCI-express x1 or x4 ?
Can I use the terminal block BNC-2110 with a PCIe-6259 ?
Thanks a lot for any help.

Hello,
The PCIe-6259 is a x1 lane PCI express board. Basicly, the driver software is the same for both boards (DAQmx) and programming is not different for these boards. Yes, a BNC-2110 can be used allong with this board. Last, this board should be orderable in the Neterlands without any problems. For more order information you could contact the dutch office and ask for the sales department.

Why is my executable VI not working with a PCI-6259?

I have bought a PCI-6259 which has referencing trigger capability. I wrote a VI for acquiring the data and tested the VI on my PC that has the full developmental LabView 8.2.1 package installed. The trigger is a 1 volt level that is triggered by a potentiometer ranging from 0-5 volts that I control manually. The VI works exactly how I want it to, however, now I want to use the Application Builder to create an executable to distribute the VI to the testing station PC. I then removed the PCI-6259 from the developmental PC and installed it in the testing station PC and loaded the executable VI along with the LabView 8.2.1 Run Time Engine. I open the program and it runs but I cannot get the program to trigger using the same potentiometer so it runs in an infinite loop. I'm pretty sure everything is loaded correctly and the only difference between the two stations is that one has the full developmental LabView package and the other is an executable. Would anyone know why my executable is not working?
Thanks,
Matt Kostyal

Hey Matt,
Thanks for contacting National Instruments support. One thing I'd like to see you try in the DAQ diagnostic utility. I do not suspect a bad card, but it is an executable that we can try that we know was properly built. If it doesn't work that will give us some more insight into the problem if it is truly hardware or software.
Let me know what you find.

Is it possible to read digital data using an external clock (PCI-6259 M)?

I’m using a NI PCI-6259 M Series card and trying to write my program in VC++6.0 using the functions in the DAQmx driver.
Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?
Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present.
Example 1
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxCfgChangeDetectionTiming(m_ReadTrimTask,"Dev1/port2/line6","Dev1/port2/line6",DAQmx_Val_FiniteSamps, 10);
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);
Example 2
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxSetSampTimingType(m_ReadTrimTask, DAQmx_Val_SampClk);
status = DAQmxSetSampClkRate(m_ReadTrimTask, 1000.0);
status = DAQmxSetSampClkActiveEdge(m_ReadTrimTask, DAQmx_Val_Falling);
status = DAQmxSetSampClkSrc(m_ReadTrimTask, " Dev1/port2/line6");
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);

Hello Magnus,
Thank you for contacting National Instruments.
"Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?"
The best place to look for this information would be the M Series Help Manual. There you can find the features of your PCI-6259 and what operations it supports.
"Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present."
Look at the "ContReadDigChan-ExtClk_Fn.c" example project which ships with the NI-DAQ driver. This is located at: C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Read Values\Cont Read Dig Chan-Ext Clk.
You will have to make some minor modifications to convert this to a finite acquisition, but that is simply a matter of changing the "sampleMode" parameter of the DAQmxCfgSampClkTiming() function. You will also have to route your clock signal to a PFI line and specify which line in your code.
I hope this helps.

Can I run use the traditional NIDAQ Driver with PCI-6259 M

I'm trying to run the Matlab signal processing toolox with my PCI-6259 M series DAQ card. I know that
I can't use the DAQmx driver and Matlab signal processing toolbox together. NI is obviously in competition with
Mathworks b/c there aren't any mathworks products listed although VB are listed. Is there a way I can use the traditional NI-DAQ driver with my card. Yes, I've read the discussion about using the NI commands in Matlab using a the dll. I have signal processing toolbox and I want to use it b/c it's a lot easier.
Thanks

nsm...
Unfortunately the answer is no, you can't use the 6259 with Traditional DAQ. It is only supported in DAQmx

PCI-6259 AI_Configure returns -10401 error

Hi,
I'm using MS VC++ to program an application that uses PCI-6259 M-Series DAQ card. I'm having trouble configuring and reading data from this device. AI_Configure(...) function returns with an error code of -10401 (unknown device error). What could I be missing.
OS: Windows XP Professional
NIDAQ: Version 7.3
Include file: nidaq.h
lib files: nidaq32.lib
lib files: nidex32.lib
Best Regards,
Ted

Hello Ted. Thank you for contacting National Instruments. You are getting this error because you are trying to use Traditional DAQ calls with a PCI board that requires DAQmx calls. There is a great help file called NI-DAQmx C Reference Help that comes with NI-DAQ. This file shows up on your computer as daqmxcfunc and can be found at C:\Program Files\National Instruments\NI-DAQ\Docs. For example, if you are reading in a voltage, AI_Configure() in traditional becomes DAQmxCreateAIVoltageChan() in DAQmx. Example programs can be found at C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C. I hope this helps! Have a great day!

Pulses generator on pci-6259 with QNX6

I have PCI-6259 DAQ device and I'm programming with QNX6 operating system.
I need make generator of pulses with 100kHz rate on PFI or static outputs.
Does anyone know how to do this or where can I find any examples "C++" code?
Many thanks,
Vsevolod

Hi Vsevolod-
If you are using the M Series MHDDK you can use the attached example. It configures one of the general-purpose counters on the board to output a pulse train that is produced by dividing down the 80MHz timebase on the device. See the function PulseTrainConfigure() for more information.
Hopefully this helps-

Detect and employ PCI or PXI chassis

I'm currently on a project which has historically bee based around a PCI backplane (in a desktop PC) containing a couple of PCI-6229 cards and a PCI-7833R. This forms the core of a testrig of which there are about 25 instances worldwide. In addition, we also support many rigs which are cored around a NI PXI chassis.
There is a drive to replace the PCs and we have opted for a for smaller footprint unit having fewer PCI slots. These are being equipped with an MXI extender card to a PXI backplane. This means in future, we need only keeps spares in the PXI format. Supporting two sets of backplanes containing near-identical hardware without implementing two near-identical pieces of software does present its problems: The FPGA bitmap build for the PCI version of the card will not open through the reference type for the PXI version of the card. We need to have a PCI and a PXI version of the bitmap. Irritatingly, the source code for these two is identical.
The first part of the solution is to establish which backplane we're using. This is straightforward. Supplying the VISA Find Resource function with the appropriate search string will identify if any PXI backplanes are connected. (Figure 1.)
Next, we need to maintain references to both FPGA VIs. Figure 2 illustrates how the FPGA to be used can be opened and proposes a structure in which the references to all available FPGA types (this example actually has four FPGA bitmaps which might be selected). In each of the other cases, the appropriate bitmap is selected in the Open FPGA Reference VI. Further, in each case, the reference is wired to the appropriate component from the cluster. (For calibration records, we also find it necessary to return the serial number of the card, but that portion of this code can be ignored.) Notice that the FPGA_Type component of the cluster is used to control which bitmap loads and which Ref component is used to store its Reference. This is necessary because the reference types are different for each bitmap.
Having set FPGA_Type, Figure 3 shows how to employ the selected resource. A separate Read/Write Control must be coded for each FPGA type.
Closing the resource also requires a case for each FPGA type.
I hope anyone else planning a stepped migration between backplanes can make use of this.

To program any DAQ card for use in Linux you need to use Register Level Programming. Unfortunately, Register level programming for the counter/timer products based on the NI-TIO ASIC (includes the 660x boards) is not supported.

Writing to digital port disrupting counter on PCI-6259? (nidaqmxbase)

Hello,
I've set up my PCI-6259 with an angular encoder counter, as per the C code example at http://zone.ni.com/devzone/cda/epd/p/id/5735
This appears to work great, but I would also like to use my PCI-6259's digital lines to control a TTL switch on the encoder it's measuring (among other things). If I set up a separate task in the same program and install a new DOChan to the task, it works great: I can control the TTL and measure the encoder position at the same time.
However, I would like to be able to control the digital lines, e.g., via a script, while leaving the encoder readout running continuously. I tried running the angular encoder counter example code, and while it was running, I ran the dio/writeDigPort example.
First of all, the writeDigPort took about 3 times longer than usual to run. It wrote to the digital line successfully, but as soon as it had, it corrupted the counter somehow. The angular encoder example began to spit out garbage, rather than the measured angle.
Is this just a limitation of nidaqmxbase, wherein I cannot use the PCI-6259 resource from multiple processes? I can imagine this being the case, since I think the counter setup is using a DMA.
Or is there a workaround? Any advice is much appreciated, thanks!
-Chase

I think what was meant is that DAQmx Base is not multi-thread safe. From the readme:
NI-DAQmx Base is not multi-thread safe. In LabVIEW, use the error cluster to
force execution order. In C, use only one thread to make API calls; especially
for task/channel creation and deletion.
So, if using DAQmx Base, all of your functions should be in the same thread (i.e. don't make parallel calls to the driver).
Having said this, I notice you're using the PCI-6259 which is supported in DAQmx for Linux. You didn't mention what OS you're using, but if you are able to use the full version of DAQmx I would recommend doing this. DAQmx is multi-thread safe, and provides more functionality and better performance than DAQmx Base.

How to use counter using PCI 6259

Hello, users,
I have a PCI 6259 board and use Labview 7.1.
I'd like to repetitively count the photon signals at 10ms integration time. I want cumulative counts in every 1 sec (1000ms) (or 1 min (60000ms)) And I want to save counts into txt.file which is open in excel program.
I am a beginner to use counter using PCI 6259 board.
1. Could you explain default NI-DAQmx counter terminals, i.e., CTR 0 SRC, CTR 0 GATE, CTR 0 AUX, and CTR 0 OUT?
2. How do I use them or how can I connect to count TTL pulse using PCI 6259?
3. As I mention my purpose above, which example is the first step to start working my purpose?
4. If you know good example, could you tell me about that?
5. If anyone has labview example which is similar to my aim, could you give me some tips or your examples?
Any hint, comment or advice would be appreciated.
Thank you so much for your response.
Leek2

I have never used the PCI 6259 but have used counters many times with labview, the coding should be the same independent of the board. What you want to do is finite buffered edge counting using a internal clock. The best way to do this is to look at the examples programs and use the express vi to get started, then you can use this code to customize your program exactly as you need.
To address your questions:
1. CTR0 means "counter 0" the name of the physical resource sometimes listed at GPCTR0. Each counter has 4 connections to the outside world:
source "src"(for counting input TTL signals),
gate (for synchronizing to external clocks and edges),
out (for pulse-train out operations)
and aux (specialty operations such as up/down counting and encoding)
2.For event counting with internal clocking you will only use the src this is the input from the signal you wish to count (ie PMT discriminator for photon counting).
3,4,5. Look at the count edge examples, there isn't one that does exactly what you want but I have done this with a 6602 (it has e counters) where I use one set of counters to set up a finite pulse train in your case 1000Hz with 1000 pulses, and another counter to edge count on an external pulse, with the source of this pulse routed from the out of the other counter. Then you can start the task and read when 1000 samples are in the buffer (about 1 second later).
Hope this helps,

No digital trigger signal on a PFI x-port in a PCI-6259

Hi,
I am using a PCI 6259 DAQcard (with a SHC68-68-EPM cable and version:2.9.1f0) to get an analog signal and a digital signal. The analog signal is used in NI MAX or NI Signal Express (DAQmn 9.7.5) to trigger it with the digital signal. When the digital signal is mounted on a Px/x port I can detect it. If I want to use it as a trigger signal on a PFI x- (better PFI x/Py.y-) .port I do not get any trigger quantitiy.
With a NI USB 6008 everything works quite well. Remark: The digital post is just labled as: PTI 0 and not as in the case of the PCI 6259 on the NI CB-68LPR-board: PFI x/Py.y.
Another remark is that I did not measure a voltage difference of 5 volt at the provided port.
How can I fix the problem and use a PFI x/Py.y-port for a digital trigger?
Solved!
Go to Solution.

Hey AndGar,
by trying I found one chanel on the platine with give me an trigger signal. So I can measure something but not in every chanal.
Maybe just the PFI x- ports are reserved for triggering and you need to close every other task which measures a digital signal.
*actuall I have no access to the programm*
Thanks and best regards,
Marcus

Start Counter Output on a Analog Trigger in the PCI 6259 Mseries board

Hi,
My question is regarding how to use Analog Triggering to start a counter in the PCI 6259 M-series board.
I have attatched a program here
'Mult_Device_Digital_Analog_Out_on_Analog_Trigger.vi'
and I'll explain my problem regarding this program.
I've tried to include all the details about the program in the documentation for the VI, but what the program
does is essentially output a set of digital and analog patterns as specified by an end user, and at times
specified in the front panel.
Problem 1.
I wish to start the whole operation on a analog trigger signal, in the program its the boolean "Line Trigger",
but I get an error saying that trigger type is not supported, when the M Series board manual clearly says it can be done.
Is there something wrong with my program ?
Thanks.

Admittedly, it might take a little time to find the documentation, but it is there. Also, the error you are getting indicates the proper trigger signals to use. In the help look at the analog Triggering Considerations for E Series, M Series, and S Series.
With that being said the easiest thing to do is to setup an Analog Input task configured to start on an Analog Trigger. Then, setup a digital edge trigger for the Counter task. The signal you are going to want to look for is the Analog Comparison Event. This signal won't show up by default in the list. What you need to do is right click on the trigger source constant or control and select I/O Name Filtering. Then check Include Advanced Terminals. Once you have done this you can select the Analog Comparison Event
