PCI-6229を使用するとエラー89130

これまでPCI-6229を使用して信号出力と電圧入力をするviプログラムをLabVIEW7.1で使用しておりました．
久しぶりに使用しようとしたところ，次のエラーが表示されて動かなくなってしまいました．
エラー89130 が次の場所で発生しました: DAQmx Write (Digital 1D Wfm NChan NSamp).vi
そこで，Measurement and Automationでデバイスとインターフェイスをのぞいてみると，NI-DAQmxデバイスのツリーにPCI-6229:"Dev1"とPCI-6229:"Dev2"がぶら下がっており，PCI-6229:"Dev1"の方に赤い×印がついています．これは何を意味するのでしょうか．
気がつくことと言えば，先日，PCのCMOSの電池が切れてしまって入れ替えたことくらいです．
ご回答，よろしくお願いいたします．

お世話になっております。"Dev1"は以前のご使用でPCI-6229が認識された際のデバイス番号であり、今回ひさしぶりにご使用いただいた上では同じPCI-6229を使用いただいておりますが"Dev2"というデバイス番号が割り振られております。
これが、今回表示されているエラー89130にも関連しているかもしれません。LabVIEW 7.1のプログラムにおいてデジタル出力のタスクを作成いただいているようですが、このタスクで使用する物理チャンネルが、現在「有効」として表示されている"Dev2"ではなく赤い×印で表示されている"Dev1"のものに選択されておりませんでしょうか。デジタル出力のプログラムはDAQアシスタントを使用されておりますでしょうか、それともDAQmxドライバの各関数を使用されておりますでしょうか。
よろしくお願いいたします。

How do I use a quadrature encoder as an external clock (PCI 6229)

Hello, ( a similar post has been placed on DAQ forum apologies as I did not know best place)
I have a PCI 6229 M Series data acquisition card. I want to use a quadrature encoder to be the external clock driving the acquisition of a number of signals. I have set up reading 24 signals each time a clock pulse is received using the DAQ assistant and set my external clock to pin pfi8 (I think) this is then connected to an encoder output. This works well enough until the encoder is run too fast when it appears I am either missing pulses or getting bounce.
How can I set up to clock using a quadrature encoder? I have seen a number of questions on this forum regarding quadrature encoders and reverse counting but not on using them as an external clock.
Basically I want to have the stability and "bounceless" nature of using two outputs from a quadrature encoder whilst still using an external clock. Is this just a case of configuring controls to certain pfi's? If so how is it done?
Any help or pointers would be helpful. So far I have managed very nicely by simply using the DAQ assistant and the interface it has would suggest that if configured for a certain pfi pin I could actually still use it.
Thanks in advance.
Kevin

Hi,
Well I've had alook into this for you and I'm not quite sure I understand what you are looking for.
Is it possible for you to phone back in to support?
The reason you are seeing bounce at high speeds, or indeed loss of points, is due to the sampling rate that you have set up.
What you will find is that the trigger will start an aquisition of a number of points at a certain rate. If your sampling rate is too low then you will not finish that sample batch before the next set of samples is recorded.
It is possible to use an external clock into a trigger or digital line, however this will limit the number of samples you can take to the speed of your encoder.
If you increase your sampling rates, and then configure a start trigger from a single input from the encoder you will be able to record a number of samples after a rising/falling edge. (Set the clock as an internal clock)
Hope this helps

How to check 6 digital signals change value at the same time with PCI-6229??

I am using DAQ card PCI-6229.
Channel 1 generate a digital signal.
Channel 2,3,4,5,6,7 acquire digital signals.
I want to check:
1. Whether the rising edge of Channel 2,3,4,5,6,7 occures at the same time;
2. The time delay from the rising edge of Channel 1 to the rising edge of Channel 2,3,4,5,6,7 is within a certain range.
I know I can use counter to get the two edge seperation time delay. But I only have two counter, it is two time-consuming if I check one by one.
I don't know how to check the rising edge of 6 different channels occure at the same time.
Does anyone has any suggestions?
Thanks

Hello,
You can use the DAQ card's digital input change detection circuitry to detect changes in the input, you can then use a counter to measure the relative time between samples. Please read Page 6-9 DI Change Detection Applications for more information. Let me know if this helps

How can i output a voltage on PCI-6229 port with visual basic 6 ?

Hello,
PCI-6229 card is using DAQmx, that not support VB 6 officially.
However, members of this forum found out a way to write/read on digital port with vb6 and DAQmx.
This was working well for me indeed.
Then, i wanted to output a voltage on AO. I followed the same procedure they used for DI/DO but in vain.
Apparently, the function DAQmxCreateAOVoltageChan()* causes trouble.
Using the .exe of the program, i get this error :
"error -200077 : Requested value is not a supported value for this property."
Thank you for any ideas that can sort this out.
* Public Declare Function DAQmxCreateAOVoltageChan Lib "nicaiu.dll" (ByVal TaskHandle As Long, ByVal lines As String, ByVal nameToAssignToLines As String, ByVal min As Single, ByVal max As Single, ByVal units As DAQmxUnits, ByVal customScaleName As String) As Long

How does the PCI-6229 DAQ-card communicate with CB-68LP connector block?

Hello!
I want to do a very simple task which is to just turn on/off a LED. I am using LabVIEW 7.1 and I have a DAQ-card PCI-6229. The DAQ-card is then wired to a connector block CB-68LP.
Now my problem is to figure out how the connector block communicates with the DAQ-card?
In the file I attached there is a picture of connector block and the device pinouts from the DAQ-card. But how do I know which of pinouts triggers some connector on the connectorblock?
Which are digital outputs on the DAQ-card?
Where can I read about this?

Hello asc01001:
The digital pins of the PCI-6229 are labelled as Px.y, where x is the port name while y is the channel name. For example, pin52 of the NI 6229 is P0.0; which is also port 0, channel 0 of the digital I/O of the DAQ card.
While "D GND", which are located at pin53, pin18, pin50, etc. are the negative terminal of all digital I/O of the DAQ cards.
Please advice if this helps.

Thank you,
Thongchai Phairoh.

Hey Thongchai,
Thanks for contacting National Instruments. This error is usually associated with Measurement and Automation Explorer having a problem with it's database and is usually fixed with a reinstall of the driver or repair of the driver.
You could try a few things to attempt to resolve this issue.
Attempt to repair the driver from the Control Panle and highlighting National Instruments and click, Change\Remove and highlight NI-DAQmx and click the repair button.
Reinstall the DAQmx 8.3 driver.
Upgrade to either 8.3.1, or to the newest version 8.5
Let me know if you are able to resolve this with any of these options.

PCI-6229 Digital I/O sample clock problem

Hi,
I am using PCI-6229. I need to use digital output channel to generate 20KHz 30%duty cycle pulses.
The datasheet shows DO sample clock frequency can be 1M Hz. But in may application, only 100KHzTimebase can work to generate. But acctually I need at least 200K Hz.
Attached is the Vi I made. Can anyone help me with this problem?
Thanks
Solved!

Digital pulse_DO Channel.vi ‏26 KB

Hello All,
I tried to modify the VI posted in this thread in order to aquire a digital signal with the PCI-6229. Sinc the frequency of the signal is below 1k i tried to devide the signal of ctr0 respectively of freqout by 8 or 16 since 6.25k or 12.5k sampling frequency would be more than enough for my purpose. By the way, when I am using the 100k timebase for the timing of the task the programm is working. Since i try to monitor up to 20 channels, the amount of data genereated is too much. Therefore I tried to use the modified VI.
Sometimes, the VI works, but almost always, the DAQmx - Read VI doesn´t terminate.
Has anybody an idea what i did wrong?
Thank you for your assistance.
Sincerely,
Mirko

Counter output PCI 6229

Hi all,
i have a little problem with NI pci 6229. I want generate a pulse train on both counter CTR 0 and CTR 1. I look the example that run on machine but i dont find the pin , with the oscilloscope, with y train pulse. I check the between Dgnd and PFI 8 ( pin2 ) but i dont see a train.
How can i solve ? What is the correct pin couter out on NI PCI 6229 ? it is referred to Dgnd?

Hi,
the terminal for a counter output task is PFI12 and not PFI8. The PFI 12 has the default Pin number 2.

Counter Output Pin on PCI-6229

I am using NI-DAQmx 7.3 C API with (among others) a PCI-6229.
I have used DAQmxSetCOPulseTerm() to connect a counter output to a terminal other than the default. It seems to work- the output pulses do, in fact, appear at PFI 6 (the terminal I'm using for testing). But the pulses continue to appear at the default output pin as well.
Is that expected?
In order to reverse the situation, I used DAQmxResetCOPulseTerm() just before calling DAQmxClearTask(). The function returns zero, but if I subsequently make a new task to do pulse output from the same counter, pulses appear at both PFI 6 and at the default pin.
Am I missing something?

Are there any DAQmx examples available for use with pci 6229 M series card?

I have been searching around for examples which work with the pci 6229 M series DAQ card. Most examples do not list this card as applicable and the one I have found gives an error. Is there anywhere specifically available, what I am particularly interested in is seeing an analogue channel being triggered by another analogue channel reaching a certain value.
Thanks
Kevin

Hi Kejoglo,
You are right in the fact that the M-Series card is newer than LabVIEW (and therefore the examples that are shipped with it) and therefore the example finder doesn't list the M-Series cards in the list of available hardware.
Basically though, the M-Series cards work with DAQmx and not Traditional DAQ so if you just go into the example finder and search under Hardware Input and Output>>DAQmx and choose an example from that folder to run on your M-Series card. As long as you don't try to do anything outside of the specifications of your card (which I doubt you will do) then you shouldn't have any trouble running any of the DAQmx examples on an M-Series card.
Hope this helps, if you still have problems then please feel free to write back.

Continuous in- and output with PCI-6229

Hi All,
I'm currently evaluating a PCI-6229 card on RTX (and maybe InTime later on). The main goal of the evaluation is to prove we can get hard real-time, deterministic behaviour from this system in order to use it to replace our current DSP-based solution.
To do so, I'm setting up a rather simple program that should
- continuously acquire 1 channel @ 20kHz
- have a processing loop of 5mSec, ie 100 samples; this loop should be entered every 5mSec as exactly as possible
- do some simple processing in the loop (thresholding the signal)
- bring out the result on an analog output (low signal if signal is under threshold, high signal for all samples above the threshold)
I could get the basics working pretty quickly: continuous input, continous output, continuous input with dma, input using interrupts.
Trying to combine everything isn't really working out however.. Normally I'd try and try until knowing the device inside-out but now I have a rather strict timeframe so hopefully someone here can provide some insight.
Questions:
1. For the input, I can get an SC_TC interrupt each time one frame is scanned. I measured this on a scope by toggling a digital output on the card, and there's no noticable jitter on the squarewave which is a good sign.
However I'd like to combine this with DMA, but the DMA is lagging a bit on the interrupt so I end up having to poll the DMA after all in the ISR, so there's no use using the interrupt in the first place.
Is there a way to set up continuous DMA servicing and get an interrupt from the DMA system itself after 100 samples are transferred?
2. For the output, I cannot get continuous mode working with DMA, only by writing to the FIFO manually. I can preload a couple of frames with the dma, but after calling aoStart(), tDMAChannel::write() works once, but all calls afterwards return kBufferUnderflow. Any ideas?
I probably have to check when exactly to write to the DMA, but I have no idea which of the many status functions to use. Tried with AO_Status_1.readAO_FIFO_Half_Full_St() but that's not it. tried to write it on each UC_TC interrupt but that didn't work either.
3. DMA is, to my understanding, a more performant way of getting samples into the host and doesn't require to call AI_FIFO_Data.readRegister() in a loop and vice-versa for the output side. But are there really benefits in using DMA?
4. I made a basic program to bring everything together the simplest way possible: preload 100 samples in the output FIFO, start analog input, start analog output, have the ISR copy all values directly from input to output FIFO.
Putting both analog signals on a scope, I expected to see the input and about (see question5) 5mSec later the same signal on the output, with no jitter.
However what I see is the output is just floating around, in other words there is no fixed delay between output and input! How is this possible? I use the same divisor for in-and output. Is there any sample code available that achieves what I want?
5. Is there a way to start both input and output at the exact same time, eg at the same edge of a certain clock pulse? How are input and output synchronized? Can I be sure they never go out of sync?
Solved!
Go to Solution.

update: looking at the DAQmx control samples, it seems some of them set the start trigger for the AO to the AI start trigger. I mimicked this using kAO_START1_SelectAI_START_1 with the aoTrigger method, and the sync seems better now: the output starts exactly 10mSec after the input (or 5, if I preload only one frame) and stays in sync for about 25mSec. That it goes wrong.
At the moment I'm using no DMA, just one simple interrupt routine that basically does
board->Interrupt_A_Ack.writeAI_SC_TC_Interrupt_Ack( 1 );
board->Interrupt_A_Ack.flush();
toggle ^= 1;
board->Static_Digital_Output.writeRegister( toggle ? 0x00 : 0xff );
for( u32 i = 0 ; i < numSamples ; ++i )
const u32 val = board->AI_FIFO_Data.readRegister();
board->AO_FIFO_Data.writeRegister( val );
In the screenshot in the attachment you can see this goes wrong: cursor A shows the position of the input signal (=AI 0, yellow) that should be shown 10mSec later at the output (blue line=AO). Cursor B shows this 10mSec later position, and you can see there's some garbage right after the cursor. This is the data that was written to the AO FIFO in the fifth interrupt (interrupt position show in purple).
Trying to figure out where that comes from, I put board->AI_Status_1.readAI_FIFO_Empty_St() in the interrupt loop. And effectively, when trying to read the 500th sample, it reports that the FIFO is empty. Consequently the data written to the AO FIFO does not make sense anymore. But I do not understand how can this ever happen? The SC_TC interrupt is fired whenever 100 samples are read from the input. So after this interrupt occurs, the FIFO should always contain at least 100 samples, no?

Counter problem PCI 6229

i am using TWO PCI 6229 cards (2*2 counters, DMA Channels), OS-winXP, LabVIEW 2009 SP1.
now using 3 counters (1. edge counter, 2 and 3 for semiperiod measurements).
i can run the edge counter alone without problem. but i cant run all the 3 counters in parallel.then the whole application slowsdown and i see the readVI at 3rd counter (buff_semi-period_continuous) not running.
i have changed the data trasfer mechanism from DMA to Interrupts but that also doesnt help.
analog input (16 differencial ) and output channels of both the cards are using.
can any one suggest a solution to this problem??
Kudos always welcome for helpful posts

Hi RENN,
the semi-period-measurement is a implicit-timed measurement. This means that there is no fixed point in time when the result of the measurement is delivered. (It depends on the signal when the driver provides you with a valid value.)
The behaviour you see is mostly caused by using multiple implicit-timed measurements in one single loop, esp. with buffered measurements.
To prevent this kind of deadlock use a single loop for every semi-period measurements.
I hope this helps.

PCI-6229 M-Series (count 3 encoders)

Hello,
I only have one DAQ board (PCI-6229 M-Series) and as I know, the board have two counters:
Ctr0 which uses PFI8 and PFI10 - now using that to count outputs from my first encoder
Ctr1 which uses PFI3 and PFI11 - for my second encoder
But I have 3 encoders, can I use other PFI pins on the DAQ board to count the outputs coming from my third encoder? Is it possible with just one DAQ board? Did I miss any example code which tell me how to do this?
Thanks alot.
