NI PXI-6259でのデータ集録におけるエラーについて(デバイスのリセット)

NI PXI-6259でBNCコネクタを介してエンコーダのパルスをトリガとして圧力や流量などのデータ集録を行っています．大体は異常なくデータ集録が可能なのですが，たまにエラーとしてデバイスをルーティングに使用できなく，デバイスをリセットするか，リセット中の可能性がありますと表示されます。このような場合，どのように対処すればよろしいでしょうか？

櫻田様
早速のご返事，有難うございます．
現在，私は以下の製品を使用させて頂いております．
・PXI-8187 RT2.5GHz リアルタイム組込コントローラ（Windows XP，Lab VIEW 7.1）
・PXI-6259 Mシリーズ多機能DAQ（BNC-2110コネクタブロックを用いて，エンコーダからのクロックにより圧力，流量のデータ集録）
・PXI-4351 高確度DAQ（熱電対で測定した温度のデータ集録）
・PXI-7344モーションコントローラ（ステッピングモータ角度調節）
上記の製品を用いて，エンジン計測および制御を行っております．
プログラムの内容としては
エンコーダからの1P/Rのトリガによりデータ集録を開始し，360P/Rのクロックを元に圧力，流量のデータ集録を行っております．
今回生じたエラー（毎回起こるわけではなく，たまに起きるのですが）はおそらくデータ集録を開始する以前のVI｢DAQmx｣で生じ，エラー番号は89130で
｢デバイスをルーティングに使用することができません．デバイスをリセットするか，デバイスがリセット中の可能性があるため，リセットが終了するのをお待ちください｣
との内容でした．
実際には，データ集録の際にMAXでデータ集録項目やポートなどを設定しており，
MAXの方で，テストを実行した際にも同様のエラーが発生しました．
エンコーダからのパルス信号に異常はないため，
やはり，PXI-6259の問題なのでしょうか？
ご返事，宜しくお願い致します．

Three Counters in PXI-6259

Hello Everyone,
I'm trying to measure time t in the picture that I have attached. I am using a PXI-6259 for this (both input and output). My first idea is to use one counter to generate the input, another counter to time when to stop the first counter and the third counter to measure time t. However, I find difficulty in getting the timing correctly, especially, the second timer.
Do you have any ideas on how to do this?
Thanks

Hi P.Jack,
I would like to ask for a bit more information about your
project and DUT. Creating a pulse as input for the DUT is not a problem. Examples
can be found in the LabVIEW example finder ((Help >> Find Examples…
>> Hardware Input and Output >> DAQmx >> Generating Digital
Pulses). Please keep in mind that the finite pulse train uses both counters
(one to generate the train, and one to count the number of pulses that have
been generated). Continuous generation only uses one counter, leaving you with
a free one. On that note, I would like add that the 6259 only has two counters.
Is the DUT output a TTL signal ? Also, is this a stimulus
response system, where t can vary in the time it takes? (that is the impression
I gathered from the picture). The overall task you are looking to accomplish
cannot be completely done in hardware with the PXI-6259 because there are only
two counters on the board, and this entire program would require four counters..
If hardware timing is essential, I would suggest a PXI-6602 counter/timer card.
This will allow you to use two counters to create the pulse train, and another
two to do a buffered counter acquisition.
If partial software timing is OK for this project, than the
6259 can accomplish the task. I would do a pulse generation, and then once this
is complete (time T starts), you can clear the task and create a buffered
counter task. Instead of creating another task, you may also think about doing
a digital read on the input line. You would put the read in a loop, and
constantly monitor the line until it goes low. You would put tick counts before
and after the loop, then compare them and see how long it took for the digital
line to go low. Either route is software timed because it requires configuring
and starting a new task at a minimum.

How to send a SQUARE WAVE to PXI-6259 over the LAN

howcan I send a SQUARE WAVE to PXI-6259 over the LAN, is
there any example or link any one can send me , thanx in advance.

Dear HaI L,
I managed to send a test signal (sine wave) to the device by choosing
the test panel option and choosing Analog output. In the analog output
I could many channels to choose from. ai0, ai1.ai2 and ai3.
I did this by right clicking NI PXI-6259, in the NI DAQmx devices
located in the Devices and Interfaces and choosing test and saw it on
an Oscilloscope without using the NI DAQ OPC capabilities, and I cannot
understand this thing.
1)How can it be possible without making a NI DAQmx channel and Variable?
2) I cannot create any channels in the devices and interfaces located
in My system but I can create NI DAQmx Global Virtual channels easily
in Data neighbourhood in the remote system, Plz tell me why?
3) I want to create a program and choose a channel to send the
signal, can I choose the channel that i create in the remote
system device ? and if yes how can I choose this ?
Thanx in advance.
Sincerely,
Munir Afzal Bhatti.

Does NI PXI-6259 support both Traditional DAQ and NI-DAQmx of Labview 7.0 Express?

I need to buy a Multifunction DAQ board which will be supported by both the Traditional and NI-DAQmx of Labview 7.0. Is the NI PXI-6259 appropriate for such application?
Thank you.
Ujwal

M-series boards are not supported by Traditional NI-DAQ. Stick with the E-series if you require Traditional support.

DAQ-PXI 6259

Hi,
I am using Labview 7.1 and NI PXI 6259 DAQ card.
I want to configure 'n' no.of digital channels at a time but each channel has to stop the task at different time.Is it possible to do this??
Suppose consider i need to configure some 8 digital channels in that i need to write 4 channels continuously and 5th channel for 5 seconds,6th for 3 Seconds,7th for 2 seconds,8th for 10 seconds.I will come to know abt the no.of channels and whether it is for continuous or for finite time only at run time.Is there any method to configure the virtual channels by grouping all 8 channels but stop each channel at different time??
Plz help me in this
Regards
Meenatchi

Hello Meenatchi,
It appears what you are trying to do is to use synchronized digital output so that one sample is output on all of your lines at the same time, for different lengths of time. If this is the case, then what Britoa suggests is probably the best way to go about it. You can programatically "decide" what you want to output and then build a digital waveform to reflect the behaivior you want to see. For example, if you wanted to output at 1kHz and you wanted channel 1 to output continuously while channel 2 only output for 1 second, then you would programatically construct a waveform where channel 2 was set low after 1000 samples. The example that I would start with would be the Cont Write Dig Port-Ext Clk-Non Regeneration.vi
As far as having different tasks running, the only way you can do that is if you use software timing (1 sample On Demand) for the different lines. You can then create a different task for each line and stop them independently as shown here:
Your lines will not be synchronized, but you could then use a case structure to decide whether to write to each line or not.
I hope this gives you a place to start, post back if you have any issues programming this.

Error in reading voltage using DAQmx with PXI-6259

Hi,
We are trying to acquire analogue voltage from 5 channels using PXI-6259. We trigger the data sampling with clk 0 (i.e. using PFI 12).
The problem we had is:
1)When we tried to get voltage from 5 channels, we get 2 data at the same after twice the period. For example, If we set the
sampling rate to be of period 1 second, we get 1 signal at 2 second and around (2+t), where t is a random time less than the execution period of the loop.
Then the next cycles would be 4 second and (4+t).
2) This timing problem did not occur if we only acquire voltage from 2 or less channels.
3) We tried to run exactly the same program with NI USB-6210 and everything worked just fine.
4) We replaced the DAQmx read with DAQ assistant and still encountered the same problem.
Attached is the a simple program that showed the error. Is this possibly a bug in PXI or DAQmx?
Please help us

Good afternoon Nitin,
Thanks for contacting National Instruments with your issue, we'll try our best to resolve it for you as quickly and efficiently as possible.
As the error message stated:
"Analog input virtual channels cannot be created out of order with respect to their physical channel numbers for the type of analog device you are using. For example, a virtual channel using physical channel ai0 must be created before a virtual channel with physical channel ai1."
If you need to randomly switch which channels you want to either control IEPE excitation or coupling on, a better approach rather than having all of these channels in one task as you've done in your attached VI, is to parse your program down to multiple tasks that can run simultaneously.
I have attached a screenshot of this approach, which hopefully is not a compromise to your application.
Best of luck with your project.

PXI-6259 2 KHz signal acquire, sound

Hello:
I working with a brakin product ABS motor, with a PWM at 2.8 KHZ, my setup:
-PXI-1042Q Chassis
-PXI-6259 Analog acquisition card.
when I fire the motor in order to measure the peak current and the motor stable current, a sound coming from the PXI chassis like if the Analog card reproduce the 2.8KHZ signal in sound, if i reduce the frequency from the product to 2KHz the sound is loud,
my question is is a NI application engineer can tell me if this is normal or if I violating a card o chassis parameter, the voltage that I reading at peak 1.1 VDC aprox, and 0.1 and state stable,
attached you can find a complete data coming from the product to the analog card.
the results are good just is bother me the sound,
thanks in advance

The frequency and voltage range that you are using are definitely within specifications for the PXI-6259, and if you notice a sound from the chassis, it is due to the fans, which I agree with you it can be very loud. The fact a slight change in frequency would produce a different sound from the chassis is rather strange. Not sure if it's just the noise volume that increases, or if it's like a high pitch sound changing.
What would be more useful is that you record this noise to a .wav file (hopefully good quality audio) and upload it here, to determine if the sound is normal or not.

PXI-6259 wiring

Putting together another data acq. system that has PXI-6259 cards. Attached is how I have typically wired in the past with TBX-68 terminal boards, however when I go to ni.com and look and the manual it does not agree with my typical witing scheme. Any idea why they dont agree?

You have it correct. For channel 1 (technically channel 0, because we like to 0-index everything) in differential mode the DAQ card takes inputs on AI1 and AI9 and compares the two values. It doesn't reference directly to ground, but instead references one to the other. This document might do a better job of explaining it: Field Wiring and Noise Considerations for Analog Signals. The scheme we have for differential inputs is to typically have the inputs be 8 AI channels apart (AI2 goes to AI10, AI3 goes to AI11, etc.)

How to synchronize NI PXI-6534 and NI PXI-6259?

Hi,
I am trying to output a continuous analog waveform (sine, dc, ramp, etc) using an AIO card (6259) and a DO pulse (using the PXI DIO 6534 card) with a customizable Duty cycle in each period of the AO signal. I need them to be in sync. Both cards reside in the NI PXI-1042Q chassis. I am using this solution as an example but can't get it work.
Also, my DO card cannot write high-frequency pulses on one line - I should instead use the entire port. It also cannot produce CO pulses.
Can anyone help with a simple vi? What is the correct way to synchronize these two cards (I am a beginner in LV) in one crate?
Thanks in advance,
~Paul

Hi Paul,
I see that has been a while since there were no activity here.
Did you manage to synchronize them?
Basically, you can synchronize them by using the PXI backplane clock. A very nice tutorial can be found at the following link http://www.ni.com/white-paper/11369/en

PXI-6259 simultaneous updating of AO

Hi, I have PXI6259 M series DAQ cards. Each card having capacity for four analogue outputs with update rate (if using all four) of 1.25MS/s. My overall goal is to be running 11 analogue outputs (using 3 cards) all running at 1.25MS/s. I want to update all channels at the same point in time - I do not want sequential updating of the channels. I have searched the examples but can't seem to find anything that specifically gives me pointers as to how I ensure each channel is updated at the same time. The timing of the updates is important too, so I want to have some kind of hardware timed execution. Currently I'm researching but soon I shall begin to program and measure in the lab. - I'd like to make sure I don't go tearing off down the wrong track! Any hints and tips of what to look out for would be really appreciated. - I'm pretty new to this!
Regards,
George.

Hello George,
Hopefully I can shed some light on this for you. A task such as this would be programmed using VIs which form part of the driver. You probably already have the driver installed - DAQmx.
A great start for getting to grips with DAQmx is this set of tutorials found on ni.com:
http://zone.ni.com/devzone/cda/tut/p/id/5434
You configure settings like finite sampling, sample rate etc in your DAQmx task.
Moving on from there, to ensure all your cards are properly synchronized you have to ensure that each card is using the same sample clock. You will need to route this clock over the RTSI bus. Thank fully DAQmx makes this really easy. See this for a nice example:

PXI-8532 DNET card is not detected in MAX

Hi all,
I'm using NI PXI-1031(4 slot PXI chassis). I have the following cards in the respective slots
Slot 1= PXI-8106 Controller
Slot 2= PXI-6259 card(AI)
Slot 3= PXI-6509 card(DI,DO)
Slot 4= PXI-8532 Card(DNET)
In MAX(Measurement & Automation Explorer), I was expecting all the above cards(PXI 6259, 6509 & 8532) to be detected under Devices and Interfaces. But only the AI and DIO cards are detected in MAX under Remote Systems>>PXI>>Devices and Interfaces.
PXI-6259 (PXI1 Slot2)
PXI-6509 (PXI1 Slot3)
The device net card, PXI-8532 is not detected in MAX. Does MAX shows/detects the DNET card?
In MAX, I selected Tools menu>>NI-DNET>>RT Hardware Configurations. Then a window prompts for RT IP address. After entering the IP address, I pressed OK. A message appears that no device is found.
Can any one help me how to detect the DNET card in MAX and do the DNET port configuration?
DNET driver version - 1.6.4
Thanks,
Raja
Solved!
Go to Solution.

Dirk,
Thanks for the reply. After updating the new driver, I am able to detect the DNET card PXI-8532 in MAX
New driver - NI-Industrial Communications for DeviceNet 2.1
But Im not able to configure the Device Net port. In MAX, I selected the menu option Tools>>NI-DNET>>RT Hardware Configurations. Then a window prompts for RT IP address. After entering the IP address, a message appears that no device interface is found.
By default, the DNET0 port is configured for the card in MAX. So I tried to communicate from LabVIEW using DNET0 port.
After installing Devicenet 2.1, an additional function palette has been added for DNET in LabVIEW.
Old DNET function palette - Instrument IO>>DNET
New DNET function palette - Industrial Communications
My original application was written with old function palette VIs which corresponds to DNET 1.6.4 version. In the download link that you shared has a description about the driver compatibility. The description says still the DNET card PXI-8532 is compatible with NI-DNET 1.x LabVIEW VIs.
With the old DNET VIs, I tried to establish communication with DNET interface port "DNET0". But it shows error while opening the interface.
Error Code ="-1074388957" - The Interface is invalid or unknown. Solution: Verify that the interface is assigned to a specific port within the Devices and Interfaces branch of the Measurement and Automation Explorer (MAX).
With the new DNET VIs(DNET 2.1.0), Im able to open the DNET interface successfully. But my original application was written in Old DNET VIs (DNET 1.6.4).
1. Do you know why the DNET 1.6.4 LabVIEW VIs are not working with PXI-8532 DNET card?
2. Can you help me how to configure DNET port in MAX for PXI-8532 DNET card?
Thanks,

How to Generate Synchronized pulses across two separate cards on a PXI system

Hey,
I'm trying to generate three pulses from my PXI System for triggering purposes. I have two cards (PXI 6259 and PXI 6115) , each with two counter/timers on them. The 6259 has 32 bit timers, and the 6115 has 24 bit timers.
Up until now, I only needed two pulses. One was 180us long at 20 Hz, and the other is 5us at 20 Hz, starting 150us after the beginning of the first pulse. I was able to achieve this by generating both pulses on my 6115 card by triggering the shorter pulse off of the rising digital edge of the longer pulse and giving the DAQmx Counter/Timer task an initial delay of 150us.
The third pulse needs to be identical to the short pulse, only it needs to occur 20us early (130us after the start of the wide pulse). I tried to generate it using the same technique as I used when generating the short pulse, only generating the pulse and reading in the rising digital edge trigger on my 6259 card instead of the 6115.
The result was that my pulse trains were asynchronous and the pulse generated on the 6259 card was constantly shifting to the left.
This puzzled me, so I wrote up a little dummy program to test generating triggered pulses. The results were that when I generated two pulses on the same card, they were always synchronized; however when I generated pulses on separate cards, one of the pulses always shifted.
I was hoping somebody could suggest a reason that the pulses across cards are asynchronous even though I'm reading in a digital trigger and hopefully a way to rectify the situation and synchronize all of my pulses.

The problem, in a nutshell, is that the timebases on the two boards have manufacturing tolerances that will cause them to differ from one another. The accuracy error is a small fraction of a percent, but the effect on the phasing of your pulses will be cumulative. That's why you saw the one set of pulses "shifting to the left."
The solution is to make sure each board derives its pulse timing from a single common timebase. Fortunately, this is pretty easy to specify with DAQmx, just a little tricky to find. In the chain of VI's you call to configure the counter pulses, insert a DAQmx Channel property node. From memory, I *think* you should be looking under something similar to "Counter Output->General->Timebase->Timebase.Src"
Right click and create a constant or control to define the timebase source. You should get a dropdown list that includes a wide variety of choices. Among them are each of the boards' 20 MHz clocks. By default each task will use a timebase from its own board but this technique lets you route one board's timebase over the PXI backplane with that single property node setting. DAQmx does most of the dirty work behind the scenes.

How do I use the PXI_clk10 backplane clock? It's not there!

Hi, folks!
This might seem a trivial question, but I'm completely at a loss here. I have made an RT-project in LV8 which (among other things) samples data continuously from two cards located in a PXI-system. All 32 (16+16) differential channels are used and one task for each card is configured in MAX. Since signal phase is an issue, I need to synchronize both tasks accurately. The lv8 code examples have a couple of VIs that should have been directly applicable to my situation, and I have studied them (and lots of others) in detail.
I have attached one example below that seemed to be spot on, and it makes use of the external PXI_Clk10 clock located in the pxi backplane. Here the confusion starts. When you attach a constant to the "source" input of the "sample clock" VI you get a drop-down list of possible sources. In the example code, PXI_Clk10 is chosen in this list, but when I try to do the same I discover that this option is simply not present. Only internal timing sources (located on the cards) can be chosen. If I configure the timing of the tasks directly in MAX, the PXI_Clk10 is an available option, but this leads to a vague error message when I start the tasks saying roughly that "it might be that you did not specify a name for the external sample clock...".
I have tried everything. My PXI-settings in MAX, routing signals via PFI-pins (didn't work at all), etc etc.
What is going on? Also: when routing a signal through a pfi-port, does this necessitate connecting the pfi-connectors physically or is the signal routed internally through the backplane? It doesn't help that I use BNC-2110 connector blocks. How can I be sure that the connectors on these blocks actually correspond to the terminals on the cards? I can't find a wiring diagram anywhere on the web.
Some facts: PXI-1031 chassis with PXI-8184 controller (dual boot) and two cards PXI-6229 / PXI-6259. These cards are located in slot 3-4.

Multi-Device Synch-Analog Input-Cont Acquisition.vi ‏77 KB

All PXI chassis produce PXI_CLK10 on the backplane (from an on-board 10 MHz oscillator), and most of them can also receive a 10 MHz clock from Slot 2 and broadcast that on the backplane. Some models can receive 10 MHz from a BNC connector on the back. Similarly, both 10 MHz and 100 MHz clocks are always available on PXI Express chassis.
Unfortunately, the 6143 and 6133 have no provision to connect to PXI_CLK10. This is likely because the master clock on those boards is 20 MHz, and there may not have been board space or room in the cost budget for a PLL to lock it to 10 MHz. Many other PXI products can use PXI_CLK10, such as the 6120. There is a list of products which use CLK10 and other PXI features here:
http://digital.ni.com/public.nsf/allkb/F4AD3B87DC8CD62E862571E3007042E5
I suspect this list is a little outdated; perhaps someone reading this knows where a more updated version is.
Hope this helps,
