Are there any decent alternatives to NI hardware like analog input modules when it comes to DAQs?

I'm talking about equipment combos like this:

• NI-9208 (24 bit, 16 channel analog input module) and maybe cDAQ-9188 or cDAQ-9174, or some other model.

For example, I've seen and know that there's much, much cheaper alternatives for industrial control if using something like a PLC. But most of those AFAIK have analog input modules that reach 16 bits, and that's not considering the differences in scan rates, for the acquisition tasks, etc.

For example in the case of those module its 500S/s. (Pretty sure its aggregate and at high-speed mode though)

- Edit: Forgot to mention, all the ADC inputs of these are Isolated too right? They also have a lot of certs.

What other options are there besides NI hardware for these tasks? I also know Keyence has equipment, but its also really expensive I think.

Plus:

Just in case, you may be wondering if me researching alternative equipment is cost effective / would save cash. But my salary for a month is much less than just one module from NI. ( I'm in a developing country. )

Does anyone have some experience with 3rd party solutions? Any known daq devices vendors? Standalone ethernet daq modules?

I am curious if anyone could provide me with any pointers as to how to set up a project for FECA-01 or point me in the right direction.

Thank you in advance.

Has anyone worked with the MIL-STD-1553 bus before? Specifically, is it possible/practical to convert between 1553 and RS-232, or between 1553 and Ethernet?

So this is a blatantly repost from the discord channel but I'm getting kind of desperate here. I have opened an issue with the NI support function but I figure I might as well try the rest of the community here too.

This is a copy and paste of my problem description which I have sent to NI and it is very similar to what I have written in the discord channel:

I am building a new PXI-based test system that duplicates an older system which has been working reliably since around 2019. The purpose of this setup is to provide absolute time to an FPGA so that all FPGA read/write signals can be timestamped correctly.

The timing architecture is as follows:

• A PXI-6683H generates a custom 1 Hz pulse using NI-Sync.
• This pulse is routed over PXI_Trig0 on the backplane.
• In the LabVIEW RT application, on the falling edge of the pulse, I write the next whole second value to the PXIe-7820R through a front panel control.
• On the rising edge, an FPGA loop is expected to trigger, latch that value as valid, and update the FPGA time function.
• Between pulses, the FPGA time is advanced using the FPGA internal 40 MHz clock.

To verify that the FPGA loop has triggered, the FPGA sets a status indicator to 1, which I read back from the RT side. In the failing system, this status always remains 0. I also observe that other FPGA functions appear inactive. Based on this, my conclusion is that the FPGA is not seeing the trigger, or is not responding to it.

Important context:

• The same software and FPGA firmware concept works in another chassis, a PXI-1062Q.
• The new system uses a PXI-1084 chassis.
• I am aware that the PXI-1084 is divided into three trigger bus segments, but both the PXI-6683H and PXIe-7820R are installed within the same segment.
• I have verified that the PXI-6683H can generate a signal.
• In MAX test panels, I can successfully drive PXI_Trig0 from the 6683H and read it back using MAX functionality, which suggests that the 6683H is operational and that PXI_Trig0 exists at least in some sense.
• I have formatted the RT controller and reinstalled software, but the issue remains.

My main question is whether there is any chassis-specific routing limitation, configuration requirement, or compatibility issue in the PXI-1084 that could prevent a user-generated PXI_Trig0 signal from being seen by the PXIe-7820R, even when both modules are in the same trigger segment.

So... anyone? I am hoping for a super obscure yet super easy solution here.

I'm having an RTSI issue between two PCIe 6323 cards. I upgraded my PC from Windows 7 or 10 and LabVIEW 2013 to Windows 11 and LabVIEW 2022 Q3. My high-speed acquisition is no longer working. I was using the counter on one card as a clock source for the other card via /Dev1/Ctr2InternalOutput. But it seems this option no longer exists in newer versions of DAQmx. I consistently get error -89125: DAQmx Start Task.vi

"Unable to find registered trigger lines between devices on this route.
If you have a PXI chassis, correctly identify the chassis in MAX and ensure it has been configured correctly. If you are using PCI devices, make sure they are connected with an RTSI cable and that the RTSI cable is registered in MAX. Otherwise, make sure there is a trigger line available on the shared trigger bus between the devices.

Source device: Dev2
Destination device: Dev1"

I can't find the RTSI option in NI-MAX. Does it still exist? Is it possible to synchronize the two cards using an internal counter?

Thank you for your help

I am facing a problem of triggering both instruments keithley 2450 (for gate control) and 2461 (for pulsed Vds and drain current measurement).

I used state machine approch to setup parameters and making voltage sweeps.

Now, the problem is to synchronize triggers between instruments.

Could someone here in the forum help me with this problem or give me an idea how to do it ?

Thank you in advance.

FET I-V Tracer_Keithley 2450 and 2461.vi

I’m looking for a precise answer regarding LabVIEW ↔ NI-DAQmx compatibility, because the official documentation is not entirely clear for recent hardware.

We need to work with a CompactDAQ cDAQ-9183 chassis.
According to NI’s documentation, this device is officially supported starting from NI-DAQmx 2024 Q4.

Our current environment is LabVIEW 2020, and the customer may consider upgrading to LabVIEW 2022.
However, the issue is that DAQmx 2024 Q4 does not seem to provide “Support for LabVIEW 2020”, and it is unclear whether it still supports LabVIEW 2022.
The public DAQmx–LabVIEW compatibility table is not up to date for the newest driver versions, and the installer no longer clearly shows which LabVIEW versions are supported.

My main question is therefore the following:

👉 How can we verify which version of LabVIEW is actually compatible with the specific NI-DAQmx version required by the cDAQ-9183?

More specifically:

• The cDAQ-9183 requires NI-DAQmx 2024 Q4 or later.

• How can we know whether DAQmx 2024 Q4 still includes support for LabVIEW 2020 or LabVIEW 2022?

• The documentation does not state clearly which LabVIEW versions are supported by the newer DAQmx drivers.

In other words:
👉 I want to know whether it is possible to use the cDAQ-9183 with LabVIEW 2020 — and if so, how?
👉 And I want to know the same thing for LabVIEW 2022.

If anyone has an official reference, a compatibility matrix, or has already tested this combination in a real project, any insight would be greatly appreciated.

Thank you in advance.

I really need some help with reading/writing defined data over the USB-8473 module.

I am not really familiar with CAN at all, so maybe it is just a small thing I am missing to fix my problem.

What do I want:

I want to write/read defined signals from my .dbc-file

In this case for example i want to write a specific value to the can signal "ISw_Stat", also I want to read some values like "CSC_val_01" to "CSC_val_12"

What do I have right now:

I managed to get a working communication up and running, also I can read/write data (but not a defined one, for now I just do all data)

What is missing:

I have struggle to do the right formatting of my data

I have attached my program so far.

thanks

Test CAN.zip

I personally will get the data from our internal systems but it seems that no one I've spoken to inside my company has ever had to receive serial number specific calibration data before.

Right now, we get PDFs with data that we have to transcribe manually into our tests.

I want to point the business / IT folks to some sort of specification but have no experience with EDI.  Some spelunking returned "EDI Specification 863" which might be right by the description...

Here is a big picture overview of what we would be replacing for now.

We have test stands that need upgraded, they currently use discrete instruments, Function Generator (4 Ch) , 4 channel oscilloscope , a Keithley 2750 , with 40 channels of DAQ , multiplexer card and relay cards ... all slots are full on the Keithley.

So, for PXI I was thinking DMM card , multiplexer(s) , relay cards , Oscilloscope and Function Generator ...

Ideally I would like to talk to someone for say 30 minutes on phone or Teams or whatever to get a better real world application feel etc..

From what I have read , we would not need a controller as the PC would be in control of everything and not offloaded to the controller.

One of the aspects of PXI I like is the ability for expansion in the future.

if you have any inclination to talk to us , message me on here and we will figure it out ...

TIA Regards

Dan

But , we are in the market for 1 or more of these instruments in working order (they are long obsolete) , we need to upgrade , but that is not a trivial task as we have stands all over the world using these things , not to mention all the software that would need upgraded to run with the new instrument. it is a painful situation that has to and will change , but , we need a few spares if we can find any.

I am hoping someone has 1 or more laying on a shelf that they no longer want 🙂

Regards

Dan

p.s. we have been searching the internet , but , nobody seems to have any.

My actual requirements are a bit nebulous at the moment but just assessing my options.

Has anyone had any luck with 3rd party software with XCP/CCP and LabVIEW? This could be 3rd party hardware or XNET stuff. Maybe a home-brew driver or vendor supplied?

I realise NI offers the  NI ECU Measurement and Calibration toolkit for XCP/CCP support with XNET hardware but I want to know if this is my only option!

Thanks!

anyway , if I configure a task to use channels , in say this order , 1,7,3,6 ....

will I get the data back in 1,7,3,6 or 1,3,6,7 ?

TIA

Dan

i have tried a few simple things and am not close the 10 Hz , i saw somewhere either on here or NI.com about buffering , but , for the life of me i cant find it again.

edit: i started with the advanced scan example.

So , how do you set up buffering , and poll the instrument at regular intervals ?

i did all the configuring outside of the while loop , and only triggered and read (into a queue) in the DAQ loop , but , it seems as though i am still a little shy of the 10Hz.

Any pointers ?

I am using a PCI-6110 DAQ and the purpose is to synchronize a DO with some AO.something like this:

Now, im using AO/StartTrigger to trigger a DO,however,this works fine on PXIe-6341(another card for test),but unable to work on PCI-6110

there is an error -200077 and it asks me to change sampTimingType from SampTime to OnDemand,obvious there is no such thing in DAQmx Timing VI.

Finally I choose to use a Timing Node to set sampTimingType as OnDemand, and a new error -200452 come.

Is there a way to solve this problem?

By the way,this VI would run on a LV2012 computer ,so some newer function may not work.

Here I post a example VI :

example.vi

For the acquisition chain, there is an acoustic sensor attached to a rod and a hammer. On the second VI, I want to record the data right after I strike with the hammer to capture the vibrations. How can I achieve this?

Additionally, I want to define a specific number of samples, but whenever I set it, the receiving VI freezes.

my goal :The DAQ will output some control signal and the FPGA will acquire some other signal and they are synchronized .

what I tried:

1. output a digital signal to 5732, however its DIO port somehow dont work,and that force me to input signal using AI port,but there are much much noise

2.this chassis used to run ScanImage(   https://docs.scanimage.org/   an program based on MATLAB using DAQmx API),so Im sure the same thing could be realised using LabVIEW,however I couldnt find a way to do so.

So ,is there a way to synchronize there two device?Or are there some modules like DAQmx  avalible?(examples of 5732 only demonstrates Clock Select and Streaming) 

Hope this will help someone.

Regards,

Craig Dobis

Here's the problem. We occasionally get error -50103 which states that "The Specified Resource is Reserved". I was able to find an NI knowledge base entry, Causes of NI-DAQmx Error 50103 "The Specified Resource is Reserved", which addresses this issue. Basically, the problem is that DAQmx Read is reentrant and I'm trying to read two channels (using separate DAQmx tasks) on the same board at the same time.

Why would this cause an error? The DAQmx Read VI has a "timeout" input that defaults to 10 seconds! Why can't DAQmx Read simply wait until the resource is no longer "reserved" and then read the channel. If the resource does not become free before the timeout occurs, then I am fine with getting a timeout error or even error -50103.

IMO, this is either a bug or a very poor design of the DAQmx API/behavior.

My solution is to create a wrapper VI around DAQmx Read which implements a retry (in a While Loop) when error -50103 occurs, until the timeout expires. I'm also going to contact NI to see if I can convince them that this is a bug or valid feature request. Either way, I'll post updates here if I learn anything from NI.

Does anyone else have experience with or thoughts about this issue?

Thanks,

-Jim

The boards are Ok, but i can understand why, in some PC, when I try to make a self test with traditional DAQ in MAX , I get a "The device did not pass the test" error. (with DAQmx the self test is passed without any errors)
Having a look at the detailed error, it is a -10461 resourceReservedError, but there is no application or nothing else that can reserve the board. Is a brand new XP installation.
Any Idea on how to solve?

thank you so much.

I am working on a project where I need to synchronize a V-data IRIG-B Timecode Generator with a high-speed camera using an NI myDAQ device, and I’m controlling the setup with LabVIEW.

Objective: I aim to ensure that the IRIG timecode from the generator matches precisely with the timecode used by the high-speed camera, for accurate timestamping and synchronization of video frames.

Current Setup:

• V-data IRIG-B Timecode Generator (Model: TCG) outputs an unmodulated IRIG-B signal.
• High-speed camera with IRIG-B input for synchronization.
• NI myDAQ device for data acquisition.
• LabVIEW for data processing and control.

Challenges:

• I am unsure of the best way to configure myDAQ to accurately capture the IRIG-B signal and how to compare this with the camera's internal IRIG implementation.
• I need guidance on processing the IRIG signal in LabVIEW to match it with the high-speed camera's timecode.

Specific Questions:

1. What are the best practices for setting up the myDAQ to read an unmodulated IRIG-B signal for maximum accuracy?
2. How can I process the IRIG signal in LabVIEW so that it is in a format that can be compared with the camera's timecode?
3. Are there any known issues or considerations when using myDAQ with IRIG timecodes and high-speed cameras that I should be aware of?
4. Is there example LabVIEW code or VI that demonstrates handling and decoding IRIG-B signals?

Attempts So Far:

• I have the myDAQ setup to read voltages, but I'm uncertain if I'm capturing the IRIG signal correctly.
• I've tried thresholding the analog signal to create a digital representation but I'm not confident in the accuracy.

Any advice, example VIs, documentation, or tips you could provide would be greatly appreciated. Thank you in advance for your assistance!

Best regards,

- Joseph P.

I am trying to get a PXI 6562 up and running.

I want to save a pre-generated pattern to the card and just repeat it continuously.

Everything seems fine till I go over a clock rate of 25Mhz, then I get an error 0xBFFA4C3 which tells me that the card cant keep up with this sample rate.

Is there a tweak I can reach up to 100Mhz? Is there any description about this behavior? At least I cant find anything 😕

thanks in advance!

I have in my possession a NI PCIe 6346 card. I want to do fast acquisition both on a counter input and on several analog inputs. Ideally, the threshold of one analog input should trigger fast acquisition on both. 

1) I've managed to do this for the analog input task, but it doesn't work for the counter task (conditions 4 and 5).  Does anyone have any ideas? 

2) I've replaced my analog trigger with a digital trigger. Can anyone tell me why condition 2 is NOOK, but condition 1 is OK? For me it was two methods doing the same thing. 🤔

3) Does my VI start the 2 tasks at the same time (I've seen examples of condition 3, but I'm not familiar with them)?

So , does anyone have any recommendations .... you can find them anywhere from $20 to $600

obviously it needs to interface with NI-MAX , although I am sure they all would..

After mounth of continuosly running with zero problem, now I'm getting the error "-200557 Specified property cannot be set while the task is running. Set the property prior to starting the task, or stop the task propr to setting the property".

First I got the error on my program (basically, a QMH acquiring data from a DAQ module). But I get the same error from the MAX Test Panel of the module, even after many restart of the Windows PC and even after I uninstalled and installed again the DAQmx drivers and the LabVIEW runtime.

This is the error and the MAX window. The module is a DAQ NI 9215 and is mounted in the cDAQ-9171 USB chassis.

In other PCs where the same LabVIEW program is running, with the same combination of hardware (9171 + 9215) the typical MAX device list is like that:

with the chassis 9171 listed and the 9215 is listed as a board in the chassis.

Unfortunally the PC and the boards are in a remote location and, at the moment, I'm not able to phisically unplug the usb chassis or change the board with a different one.

Can somebody help me, suggesting something else I could try, having only a remote access to the Windows PC?

Thank you,

Marco.

I have created my own vi where i read continuously Data from digital DIO(channel 9-16) and save them successfully in my database.

I have a micro controller-encoder-transmitter and on the other side a receiver-decoder-Hytek-PC

The micro-controller is sending a 255 header followed by 14 bytes each for a different sensor. The problem i am facing is that i need a some sort of trigger to only read when change of state so that the one byte don't overwrite the other. in my case my hytek is reading 255-255 for all my data.

I need it to read only when it s triggered so i don t have overwrite.

Can i use the trigger input for digital input as well?? i was thinking about connecting the trigger input to the vt(trigger) of the receiver. but i dunno if it will work on labview.

I am enumerating...opening session...read/write IO and closing the devices each time. but i need it to read each time i send a new byte. how can i do that?

i would appreciate any help.thank you

Thanks!

Once upon a time, our company stocked up on NI controllers and systems.  Due to business reasons, we are getting out of the NI integration game.  Lots of goodies we're looking to sell, most of stock is brand new in box or barely been used.  Check these out:

[FS] Several PXIe-8880 and PXIe-1082 units, w/ extra RAM

[FS] cRIO-9035, cRIO-9065, cRIO-9034, cRIO-9032

[FS] sbRIO-9606's brand new in box

NI 9697 mezzanine card for sbRIO, $250USD

[FS] NI-9239E (24-bit, 4ch, 50kS/s) $300USD per unit

(The NI-9239E is just a NI-9239 without the enclosure, it functions exactly same as a $2000 NI-9239, see this video from Linkedin)

Oh and if you're looking for NI parts and don't want to get ebay-scammed, here's the NI Trading Post forum.  Maybe it should have been a board in LAVA?  The group is on linkedin as well: https://www.linkedin.com/groups/14121153/

If you do can you let me know the part number?

I'm working on netboot and need to increase my RAM from the 4GB included.  Yes, I know NI sells NI part number 783001-8192, but I am expecting a ridiculously high quote for something that should only cost $200 maximum in the worst case.

I'm thinking Micron MT16KTF1G64HZ-1G9P1, Memory Module DDR3L SDRAM 8GB 1866MT/s 204-SODIMM would work, just rather know if someone has an 8GB memory that is known working.

What's in it from NI is the 4GB Micron  MT8KTF51264HZ-1G9P1 (PC3L-14900S-13-13-B4, 4 GB 1Rx8 ), Memory Module DDR3L SDRAM 4GB 1866MT/s 204-SODIMM

I was able to successfully complete the PDO mapping with a cRIO 9057 previously. 

What did I do wrong here? 

It works fine when I grap a single moment of waveform however, It always encountered an Error 1073807298: Could Not Perform Operation Because of I/O Error if I try to acquire a waveform continuously with "Agilent 2000 3000 X-Series Acquire Waveform Continuously.vi".

I matched LabVIEW 2020 and NI-VISA 20.0 for compatibility.

Has anyone an idea for this issue?

Thank you for your help!

I have a Pickering Switch PXI card, an NI PXIe-4353 (Thermocouples card) and NI PXIe-4080 (DMM). The first two show up fine using the VISA Find Resource (with "?*INSTR" as the expression), once I configure NI-VISA in MAX to "Show all devices accessible to VISA" under "PXI/PCI Interfaces". But the PXIe-4080 does not. I had loaned a PXI-4071 DMM (an older NI model), and that one shows up fine.

When we contacted NI support, they were initially confused, as if using VISA Find Resources for PXI devices was super weird or unheard of. Then they tried to claim that since the PXI 408x is completely a different product than the 407x under the hood, it cannot support VISA. We're not trying to take measurements over VISA, just find it, and get some interface information about it (we then plan on using the NI-DMM IVI). I've included a snapshot of a conglomeration of the functionality that we use to find, get information on, and then convert the VISA reference to the NI-DMM IVI ref specifically.

Again, all this worked with the NI PXI-4071 DMM, but I have two NI PXIe-4080 DMMs now that both will not even show up in VISA in MAX. Has anyone else had this issue, or issues like this? It's totally reasonable to use VISA Find Resource for PXI devices, right?

Does anyone know how to make a simulated DAQ device using LabVIEW code?

I am thinking about creating one programatically as part of some unit tests.

 Is there any way to use NI RT PXI Ethernet card for SOMEIP and DOIP  or XCP Protocol testing?

How dhcp server configuration happen in PXI RT side? 

is anyone already used Automotive Ethernet validation using NI PXI RT platform?

If yes - pl. guide.

Thanks,

Very new to Ethercat devices, so hoping some one can tell me if I'm missing something obvious.

I have a 6 axis stepper control system that uses a cRIO-9024 and 6 NI-9512 stepper controllers.  The system is getting a bit old, and with NI getting out of the motion control field the customer asked me about a possible upgrade to the system.  Since the old system used Softmotion and NI released Softmotion for Labview 2020, my feeling was that new controllers compatible with Softmotion should work with minimal changes to the existing software.  Based on what I read Ethercat drives may be a good way to go.

According to the NI website, Copley TE2 Ethercat drives are compatible and should work for our existing stepper motors. I installed all the NI Ethercat and SDI drivers and got the TE2 ESI files from the Copley website.  Starting with the NI SDI Plug-In example, I can link to the new cRIO (9049), and it can apparently see the TE2 drive, but when I go to bind the Softmotion axis to the TE2 drive, it doesn't show up.  I've run out of ideas, and since NI doesn't do motion anymore they couldn't help.

Anybody have any suggestions?

They'll be deployed in a manufacturing environment,  the facility is climate controlled, they will be in a fixed location with little chance of being struck or coming into contact with anything.  They'll be mounted to extruded aluminum framing

Ideally they are controlled via a command set and don't work on a custom DLL.  I'd like them to have a watch dog included so if a command isn't received it will switch over to RED

Thanks

Solution

These error codes indicate fairly general problems that can be caused by either hardware or software. You can resolve these errors through one of the troubleshooting steps below:

1. Reset the device in Measurement & Automation Explorer, then try the self-calibrate again.
2. Reboot the PC or PXI controller.
3. Try a different PCI or PXI slot.
4. If you are using a remote controller (i.e PCIe-8361) make sure the MXI card has the DIP Switch in the correct position, either ON if you are using BIOS Compatibility Mode or OFF if you are not.

I have tried 1, 2 and 3 => did not help.
About 1 Reset and Self-test is success but Self- Calibrate is just running for ever.
@4 If this was not setup correctly, I assume the PC would not be able to see the PXI rack and modules in it.

I have tried to delete all LabVIEW and device driver SW on the PC and then installed it again.
I still got the same error!

What could be my next step?

Our current instrument is using CVS-1459. We have a laser device in the instrument. Normally the laser has a separated controller which let us controlled by using serial port or TCP/IP. We are trying a new laser device which only allow to control through DB25 with analog I/O and digital I/O. I figured that I can use a cheap controller as myRIO since my CVS does not support DAQmx to connect with a DAQ device. Now I have no idea how to connect CVS-1459 with myRIO. myRIO uses USB to Ethernet cable. I configure the Ethernet Adapter usb0 on the CVS to the same IP subnet with myRIO but I still cannot ping it. What is the other option I can use for my connection between CVS and myRIO or option to control the laser?

Thank you in advance!

LabVIEW and coffee?  Heck yeah, any day.  You'll see my spaghetti code come to life. 😄  No, but seriously ...

I've always been a big fan of LabVIEW, and ever since NI discontinued their motion offerings, I was really sad for a while.  (Maybe because motion was also my specialty as a systems engineer at NI. 🙁)  Back in the day, NI had great motion products that worked well with LabVIEW.  They worked great for pick-and-place systems, automatic positioning, test systems where you need to move the DUT or sensor around, etc.

Well, now I left NI, and being located in Taiwan, this give us an advantage for sourcing various electronics and embedded systems.  My partners and I started TENET Technologies this year, and I pitched to them and said ... you know what?  What if we made a motion controller for LabVIEW users?  I'm reluctant to believe that, just because NI has forfeited this market, that LabVIEW users don't need motion controllers anymore.  Without NI's solution, users are burdened with having to risk compatibility issues with other motion controllers, AND also have to deal with APIs that look like dismissive afterthoughts.  I've researched many different APIs from 3rd party vendors, and usually they look something like this:

Uggh, yuck.  This really defeats the purpose of using LabVIEW, by having an ill-defined API.  We couldn't stand it anymore.  With TENET GECO Motion, we set out to make motion control a first class citizen in LabVIEW once more.  See our solution here: https://promo.tenet-tech.co/motion

So recently we just released our first version, and we're continuously looking for feedback to make it better.  I'm running a survey to get feedback for your needs and wishes in a motion controller for LabVIEW.  We can't get to everything right away, but feedback from the LabVIEW community would be SUPER helpful.  Survey is linked here: https://forms.gle/Zz31RcsaX5keS4Pg9. 

 As a token of appreciation, I'll be giving out Starbucks $10USD gift cards to 5 lucky winners.  Survey ends by the end of this week, hope to hear from you! 🙏

I use a USB 6215.
With two TTL output signals, two different colored lasers are to be triggered.
TTL 1 activates a blue laser. TTL 2 activates a green laser. 
This external device also outputs 2 analog signals that I can capture with the USB 6215.
While the lasers are active, the analog signals output characteristic values.

The two TTL signals should be output by the USB6215 as follows:
Both TTLs should be active for 10 ms every 100 ms, one after the other with a 2 ms delay.
So TTL1 active for 10 ms, then 2 ms delay then TTL 2 active for 10 ms. The times should be adhered to as precisely as possible.
The two analog signals should be calculated during the time in which both TTL are active (i.e. over the 22ms).
The analog signals are sampled at 1 kHz.
The analog data acquisition via DAQmx is clear. 
I only have problems programming the timing of the digital triggers (TTL) accordingly.
Does anyone have any idea how to start? 
Maybe someone has already programmed something similar?

Thanks in advance

I am looking to purchase any new or gently used cRIO 9047s that anyone may have on hand and don't need anymore. Please feel free to contact me here on LAVA or via email at jordankuehn@sef.energy. 

This did all work once upon a time, but the system has been out of my hands for a very long time.

NI support gave some very manual linux-ey commands to reinstall drivers or something, but I do not think this worked.

Has anyone come across a situation like this before?

Since I couldn't find a driver, I wrote a quick Labview interface with some simple commands to communicate with the instrument but couldn't get anywhere setting up the serial communication according to the serial communciation specification (see attached). I kept getting timeout's and was not able to read or write any data to the controller.

The basic settings are 9600,8,n,1, XON/XOFF (w/ XON=11 hex and XOFF = 13 hex)

So then I setup Portmon to watch the OEM's software application (which works fine). The OEM applicaiton seems to have a different setting for the "Shake:80" serial setting in Portmon. I've tried a bunch of different handshake settings using the VISA Serial Setup vi to try and match the OEM software to no avail. Also the OEM software seems to enable a bunch of Serial Events. Some of these I can enable and some I can't, but when I enable the events the computer justs grinds to a halt. Do I have to enable and handle the Serial Events or can I ignore them?

So I turn to you guys for advice. Attached is my code, the comm spec, and port mon snapshot's.

Everyone, I look for a driver for MKS pressure transducer readout PDR 2000,

If any one has one, can you share it with me please?

I have a USB to DB9 (male) serial converter, which I then to a small box which connects three wires (Rx, Tx and Gnd) of DB9 connector to the DB15 connector. And then this connector goes to the female DB15 connector of the controller. I'm reading the manual and connecting the pin 7,8 and 9 (of DB15) to pin 3,2 and 5 (of DB9 connector). But, this doesn't seem to be working as I can't get the controller detected in the computer. I can only detect the USB to serial converter. 

Do you suggest to connect the controller directly to a PC with DB15 port (without USB to DB9 and DB9 to DB15 conversion)? 

Once I have the controller's connection established, then I think it is straightforward as I can use HyperTerminal for serial communication. 

It would be great if you could have some inputs for this problem. Please let me know your inputs.

I am wondering if there is a way of  resetting a single board RIO using one the available I/Os?  (I suspect not). The context would be a remotely located RIO board (that is:  not accessible), that is programmed via a network link from another location. At times, a reset could be required, this is where having a separate system applying a short to a dedicated I/Os could be helpful. thx

Using an NI 9189 chassis with an NI 9221 Analog input card. The task is set up to capture at an 8k rate and read n samples at a time. My program reviews the values and records a 2000 point chunk to excel if there is an error with the voltages. The program needs to run for 45hrs at a time, so over a billion readings per run.

Once in a while, maybe once every three 45hr cycles, one of the errors logged is because of a 0.000000V reading. Adjacent readings are perfectly fine, and do not ramp in or out to 0. And since the 0 value is absolutely 0V I am suspicious that it is not coming from the DAQ but is instead a memory issue in the PC.

Has anyone else experienced this?

Here is an example of readings:

23.731911
23.762417
23.792923
0.000000
23.792923

1 occurrences in 3Billion is very good for consistency, but I am curious why.
If the SW is stable looping for 3Billion readings, I don't think its anything with my code. 
 

Does anyone know the cause, and solution for this problem?

below is a snapshot of the data.

The DMM is connected in series with a LED load, which is connected to a DUT.

I have a problem here. Hope I can get some help for a solution.

The task at-hand is to use an NI USB-8451 to communicate with a device over I2C. This would have been trivial if it wasn’t for the fact that the USB-8451 is connected to a PXI controller running LabVIEW Real-Time OS (Phar Lap ETS) and not a Windows PC.

I haven’t chosen the hardware combination personally and the person who did just assumed they would work together. And I did too… I mean, it's NI's eco system! Just download the NI-845x Driver Software from NI’s webpage, install it on my PC and then install whatever software needed on the controller through MAX. Easy right?

But no. It wasn't that easy.

So I wonder:

(1) Has anyone had any success controlling the NI USB-8451 from anything but a Windows PC? And if so… how?? The PXI system finds the USB-8451 and lists is as a USB VISA raw device but the supplied vi’s/drivers cannot be executed on the controller.

(2) Since what I want to do is actually very little (just writing a couple of bytes once to the I2C device) I have started to toying with the idea of recording the USB traffic from the Windows laptop somehow via Wireshark and then replaying it on the PXI system… has anyone had any success doing something like that?

(3) And finally. If it is impossible to get the USB-8451 to work with my PXI system, is there some other I2C hardware that is known to do? I’m getting the impression that NI only has this USB device apart from implementing the I2C protocol on a dedicated FPGA and that seems a little too much.

Sorry for the long post. Getting a little desperate here. Deadline approaching.

I'm running LabVIEW 2019 SP1 by the way and the controller is a PXIe-8821 if that makes any difference.

BR, E

Since I only have one device, I would appreciate it if others could try it with theirs. The state of the driver is final beta testing before release (RC1). Once I'm happy with it and proved it doesn't just work for me, it will be packaged and released (under BSD licence) so I'm looking for test pedants Since it isn't packaged, I'm looking for people that are  comfortable with using it from the project file and the IDE rather than from palettes and already have the rtlsdr and usb binaries. There is an example (shown above) so you should be up and running quickly.

If you have a RTL2838 based SDR and some time to run the example and report issues;. let me know and I'll see you get a copy.

From what I see the best way is to use thunderbolt PXIe-8301. I ve seen many notebooks with TB3 but no desktop PCs. Are there other ways what will be cheaper than PXI controller?

Thanks!

I am trying to control a voltage source (DP 8200) through VISA in LabVIEW. I have connected the instrument to my system using a GPIB connector. When I scan in MAX, the instrument shows up and switches to remote mode, but does not respond to the IDN query. I'm assuming that the machine does not have read abilities here. The commands to the instrument are very elementary. For example "V2+500000" means voltage mode - 2nd range of 100V - positive polarity - set to 50.0000 V'. However, I cannot get the instrument to respond. I have tried writing a simple VISA program attached here (that gave no errors) and I have tried using the NI 488.2 Communicator.  I have tried to remove zeros, add them, add quotation marks, add \r, add \n, add \r\n, lowercase v, with a decimal, without a decimal.... I have changed the EOS configuration settings. Any other suggestions?

Thanks!

I'm looking for a recommendation on a digital scale that I can buy that is easy to use and plays well with LabVIEW.

The scale we're using now relies on 3rd party software that is not (easily) compatible with windows 10, so setting it up will not be practical going forward.

Ideally, the scale would be able to support 3.2kg have a resolution of about 10mg . If anyone has a product they've used before and particularly enjoyed using, I'd love to hear about it.  

There is no com port, they use an ip address in the tripp-lite software. There is no network connections to the hardware so I'm guessing the ip address is being used by the software to address the USB Port.

I'm just lost, is there something in labview that addresses HID communications? Do I use VISA? Do I create a raw port and assign it a ASRL number?

Can someone point me in the right direction?

Thanks,

Bob Harmon

There is a task to acquire data from analog sensors using cRIO 9076 + NI 9234. The task is solved with FPGA and FIFO buffer (code segment is attached). Sample rate is 200 Hz. I disconnected all sensors. During debug I have an issue of appearing "bursts/needles" in the data. I was not able to find out a reason for it. What is typical, when I start topLevel VI and it receives the first package, the "needle" immediately occurs in the data (see graph in the upper left corner) and this is repeated in 8 out of 10 cases. The needles appear without any specific periodicity and affect all channels at once. Has anyone come across this behavior or maybe know what it might be connected with?

P.S.  MasterTimebaseSource parameter is set to Mod1 for all modules.

I attach an example of real buffers for viewing in VI.

I have simultaneous loops in the application communicating to the different instruments, using a sequencer of sorts to pipe commands one at a time to each of my various loops.

Has anyone seen the locking error pop before while not actually using the Lock and Unlock VIs?  This issue has gotten worse lately and it has come time to find the root cause.  My only thoughts are that it may have something to do with having NI MAX and Keysight Connection Expert both installed and possibly trying to "ping" these devices.  Every once in a while me sending commands and these "pings" may clash and cause the locking error.

Error reads as follows:

"Specified type of lock cannot be obtained, or specified operation cannot be performed, because the resource is locked. VISA error code -1073807345 (0xBFFF000F)"

I'm trying to use ni usb-6002 to measure a low level DC signal which is around 1.3 V.  I used differential set up and two 47k bias resistors. The device is connected to a laptop computer that is connected to a power outlet and is then connected to a wall socket. Here is an actual picture of the connection

However, this gives me really noisy measurement.

the actual signal should be about 1.25V.

and an fft image of it

so it looks like I get all kinds of interference.

However, if I unplug laptop's power, the measurement is much better

and an fft image

I mean if I unplug the power the measurement is much improved but still noisy. I could apply a low pass filter of really low cut-ff frequency and high order, but this would give me unbearable delay and defeat the purpose of real-time monitoring. 

So how can I take care of this noise problem? Any help is much appreciated!

The intention was to use NI VISA and direct i/o to communicate with the autosampler, which will be located close to the computer. Data transfer rate will be low.

Any advice or comments concerning reliability or any other issues on the following alternates would be appreciated.

• Output to computer COM port with direct cable connection to autosampler.
  
• Output to computer USB port and connect using NI Serial Hardware USB-232 1 port cable. Is this likely to give more reliable communication that 1. above? It would seem to have the advantage of using current technology, and also to use NI-Serial software to configure and monitor communication.
  
• Purchase a USB version autosampler. The sales history of mainly selling RS232 machines to OEM instrument manufactures left a small question mark.
  

Not having a driver is unfortunate. The autosampler drivers on ni.com/idnet are not able to be modified since the details are not disclosed. I would be grateful if anyone knows of an open source version which I could use as a starting point.

GraemeJ.

My *intended* behavior is to wait (block) at the DAQmx Trigger/Start Analog Edge on, say channel ai1, until I get a falling edge thru, say, -0.050V.  So I have a little vi (that contains 2 parallel loops) that I want to sit & wait for the trigger to be satisifed.  I'm doing "routine" voltage measurements in another AI loop on a different channel.  I want this vi to run separately from my "routine" voltage measurements because I want the app to respond "instantly" to input voltage exceeding a limit to prevent expensive damage to load cells.  I was afraid that if I used either Finite or Continuous sampling to "catch" an excessive voltage, I might miss it while I'm doing something else.  Yes, yes, a cRIO real-time setup would be better for this, but this is a very cost-sensitive task... I just want to "Arm & Forget" this process until it gets triggered, whereupon it fires an event at me.  SO... I'm also reading the same voltage on channel ai0 for regular-ole voltage measurements, and just jumpering them together.  I did this because I read somewhere that you can't use the same channel for multiple DAQ tasks - I *thought* I would need to set up the tasks differently.  {but now that think about it, the setups can be the same...}.

I've set up the DAQmx task the same as shipping examples and lots of posts I've seen.  I'm supplying a nice clean DC voltage to a 9205 card using a high quality HP variable power supply.  Using NI-MAX, I've verified that my 9174 chassis & 9205 are working properly.

THE PROBLEM - When I run it, the vi just sails right through to the end, with no error, and an empty data array out.  No matter WHAT crazy voltage I give the "DAQmx Trigger.vi" (set up for Start Analog Edge), it never waits for the trigger to be satisfied, just breezes on through as if it weren't there.  If I set the Sample Clock for "Finite Samples", the DAQmx Read fails with timeout - makes sense, since the trigger wasn't satisfied.  What could I possibly be doing wrong with such a simple task???????

So my fundamental misunderstanding still vexes me - does the DAQmx Trigger vi not block and wait for the trigger condition to be satisfied, like the instructions state - "Configures the task to start acquiring or generating samples when an analog signal crosses the level you specify"?

I stripped my requirement down to the bare essentials - see the 1st snippet, the 2nd is my actual vi.  Any ideas, anybody?

Some weeks ago I buy the new NI 9210.

Now I have a problem, as this is a newer equipement. the NIDAQ for this board does not support my old hardware.

Why NI cannot creat a spicific driver for each hardware?

When 1588 timesync is running it appear to interfere with DAQmx AI timed tasks.  I am seeing strange errors -200284 (buffer underrun) or -209836 (The devices in your task cannot be synchronized) when I start my DAQmx task with 1588 engaged. When I disable the 1553 master on my network or remove the 1588 driver from the cRIO everything works correctly.  To simplify testing I am using a DAQmx example - Thermocouple - Continuous Input.vi to do my testing. I do not have any HW sync modules just plain C series AI modules so there should be no attempt to perform any AI clock slaving since this is a software only 1588 system.  BTW I am using the latest 19.0 drivers and LV Dev.  I also see the same behavior in 18.5.  Your thoughts please...

It runs fine 99% of them time. 

On occasion i use the STOP immediate command to stop the drive

It simply ignores the command.

I have an indicator tied to the drive velocity and it shows zero

However the drive continues to move and it will not stop. 

I am at a loss. We have verified the command and tried it in several places in the program. 

After the initial troubleshooting i am thinking this is a comm related problem. 

As if its busy doing something else. 

Does anyone know of any other functions we can use to monitor the comms outbound?

I have been trying to locate a function that will tell us if the drive is busy.  

I have experience with CDAQ RT but CDAQ WES7 is new to me.

Creating such a version is a mess since you can't "save to previous' vis that refer to files in vi.lib. Should I try and do it?

Thanks in advance
