Error 10003 occurred at ULx Read(Analog Wfm 1Chan NSamp).vi?

Hello I am using the Measurement computing hardware USB-2416 and when I run the following Vi (Screen shot attached and the VI was made by following the video http://www.youtube.com/watch?v=GqyooarvbuM) I am getting the following error
Error 10003 occurred at ULx Read (Analog Wfm 1Chan NSamp).vi
Possible reason(s):
Measurements: Some or all of the samples requested have not yet been acquired.
To wait for the samples to become available use a longer read timeout or read later in your program. To make the samples available sooner, increase the sample rate. If your task uses a start trigger, make sure that your start trigger is configured correctly. It is also possible that you configured the task for external timing, and no clock was supplied. If this is the case, supply an external clock.

You have a rate of 93 and are collecting 1000 samples. Is that what you want? That is not what the video shows.
That means it takes about 10.75 seconds to collect 1000 samples. I bet the timeout for the function defaults to 10 seconds. That means you will have only collected 930 samples and thus explains why you get this error message.

Error -1073807253 occurred at VISA Read in transient SR830.vi VISA: (Hex 0xBFFF006B) A framing error occurred during transfer.

Hi,
I am have written a program with labview to make transient c-v measurement using a stanford research SR830 lockin amplifier. The program seems to be runing fine, but sometimes it is givvibg an error:
Error -1073807253 occurred at VISA Read in transient SR830.vi
Possible reason(s):
VISA: (Hex 0xBFFF006B) A framing error occurred during transfer.
Error -1073807253 occurred at VISA Read in transient SR830.vi
Possible reason(s):
VISA: (Hex 0xBFFF006B) A framing error occurred during transfer.
but if I press ok, the program again starts running. What might be the poblem? BTW I googled a bit and I see that in the labview topic "RS-232 Framing Error with HP 34401A Mulitmeter" by pkennedy32 this is what is said about framing error:
""Framing Error" in an RS-232 context means a very specific thing - when the receiver was expecting a stop bit, the line was not in SPACE condition. This can be the result of:
1... Baud rate mismatch (although other problems would likely crop up first).
2... Data Length problem, If I send 8 data bits and you expect 7, the stop bit is in the wrong place.
3... Parity setting mismatch - If I send 7 data bits + parity and you expect 7 data bits and no parity, the stop bit is in the wrong place.
4... Mismatch in # Stop bits - If I send you 7 Data bits + parity + one stop bit, and you expect 7 data bits + parity + TWO stop bits, the second one might not be correct, although most devices do not complain about this.
But, I must say that this is the same com port setting that I use to measure c-v hysterysis, but I never gt this error there.
I attach the program herewith for your kind perusal. Please help me resolve this issue.
Thanks in advance.
Solved!

@Dennis Knutson you are right I checked the read indicator in backslash mode, and instead of a \n it is sending \r. So I changed the \n in my write strings to \r. But, if I keep the CLOSE VISA outside my loop instead of inside as you suggested, the termination character appears to come in the middle of the read string instead at the end. And since the read terminates at the \r so it is displaying some junk value before the \r, but if I put the CLOSE VISA outside the loop and play along with the bytes at the read buffer, I see the whole read string with the \r at the end of the string. But, whenever the values are in exponential form (when close to zero) like 6.938839 e-5, I always get a time out error whatever be the timeout that I put at the VISA initialize. And subsequently, if I stop the program and run it again the machine program hangs and I donot get any reading. Then after I close it again and start, sometimes it hangs for some more or starts working. If I put an arbitrarily large byte count at the READ VISA, then I always get the time out before the operation completed error.
@ Ravens Fan I have removed the CSAC VI altogether and taking the CH! And CH” reading separately, instead as one string. So, no more issues with that.
I use the control at the delay so that I can choose how much delay I want to set, and I use the math operation because I am using adding up the delay time to keep track of the time elapsed. Because in the end I have t plot a time vs. CH! And CH” readings.
I am not sure but probably I am making some silly errors. Please help me out.

Error 56 occurred at TCP Read in MB Ethernet Receive.vi

My sensor uses MODBUS TCP and operates as a slave device. Currently I'm using Labview 7.1 on my PC and would like to communicate w/ sensor as a Master. I downloaded MODBUS library from ni developer zone. I want to read 14 discrete outputs (coils). I believe MB Ethernet Master Query.vi is most appropriate to use for my application. I put this block into my *.vi inside of a while loop, hooked up the connection ID, configured it with address start/quantity, and ran. The error I got says: "Error 56 occurred at TCP Read in MB Ethernet Receive.vi->MB Ethernet Master Query.vi->...*.vi". I have confirmed that TCP is working with Labview because I can receive other non-MODBUS sensor data from my device via TCP/IP using a different *.vi I created. However this data is received though a different port than the typical 502 MODBUS port. I have also confirmed MODBUS is working on my device using a 3rd party Polling Utility that reports register status.
I currently do not have NI-VISA 3.0.1, VISA Server 3.0.0, or Measurement & Automation Explorer (MAX) version 3.1.1 installed on my PC. Do I absolutely need these products to do what I need to do?
Any thoughts why I am not able to get this setup working?
Also, I am embarking on developing several MODBUS applications after this. Would it be a good idea to upgrade my version of Labview to gain more MODBUS functionality w/ Labview? I'm somewhat new to Labview and am a little confused on which products would really help me for working on MODBUS applications and if those products are compatible with my 7.1 version.

Hi cwallis2,
If you can use TCP/IP in Labview then you should be okay as far as that is concerned. The Ethernet Modbus VIs use LabVIEW TCP VIs underneath; the Serial Modbus VIs use VISA underneath. So unless you want to try the serial VIs if that's a possibility, then you should be okay without VISA.
The error 56 is a time-out error and is generated when an operation
exceeds the user-specified time limit. This error is caused by the
LabVIEW code not receiving a network response in the defined time
limit. The default time-out limit is 5 seconds, which should be enough,
although you can increase this time-out value as an input for the MB
Ethernet Master Query.vi. Since you get the time-out when you are
reading instead of the initialization lets us know that you are able to
open the TCP port correctly.
What is the address you entering into the MB Ethernet Master Query.vi in the Modbus Command constant? You may need to use relative addressing instead of absolute addressing, or vice versa.
Hope this helps!

Warning 200015 occurred at DAQmx Write (Digital Wfm 1Chan NSamp).vi:4

Hi,
Attached is the VI I write. But there is a warning: Warning 200015 occurred at DAQmx Write (Digital Wfm 1Chan NSamp).vi:4
I want to use digital channel to create an output. The duty cycle change from 30% to 50% to 70%. At the same time, measure the input of another 2 channels.
Do you have any idea about this?

Hello,
The situation that you are seeing here can be identified as 'glitching'. Glitching occurs where there is potential for previous samples in a buffer to be mixed in with newer samples written into the buffer, causing a signal output that is a mix between the old and new data you are trying to output. In the DAQmx Help document, search for 'glitching' and you will be directed to an article which explains glitching, mentions Warning 200015 is thrown where there is a potential for this to happen, and then offers suggestions on how to work around this issue, as well as two pictures that clarifies what could happen with glitching.
This warning pops up in your application since you are writing one set of data and then writing a second set of data afterwards. If you do not see glitching on your signal, you can modify your code to ignore this warning. Read through the help document for suggestions on modifications that will work for your application.

Error -50103 occuring in one program, but not occuring in another similar program

Hello,
I'm a new user of LabView and I'm trying to figure out how a part of this programming process works. Anyway, the block diagram of the working program consists of the first two pictures (C:\Users\Labview\Pictures\errorsetupnew1.jpg -and- C:\Users\Labview\Pictures\errorsetupnew2.jpg). The parts in question are the DAQAssistant9 and DAQAssistant12 in the lower half of the diagram. When I run the program, everything goes fine.
So now I'm trying to run two other programs that both share the same properties as these two DAQAssistants, but they are in two separate programs. When I run one program, it works, but when I run the other program, Error -50103 occurs at DAQmx Control Task.vi:10. Pressing continue yields Error -50103 occuring at DAQmx Read (Analog 1D Wfm NChan NSamp).vi:3.
So my first attempt at solving it was to consolidate it into one program and run it all together, however the same error shows up. I isolated the two While loops which seem to be causing the problem into a test program (third picture) and the error occurs there as well.
My question is what is different from the program in the first two pictures that is allowing the program to run correctly and the test program (which can be extended to the program that I need to work).
I'm new, so please let me know how many beginner mistakes I might be making here!
Thanks

I'm not currently at the computer with the files in question, but what if I attached those instead when I got the chance? The problem is that I don't believe I am using the same DAQ resource in two different tasks. The command line runs correctly in one, but can not run in the other even though the part giving the error is just a copy of the other program.
I'm trying to run through the previous posts about this particular error but the LabView lingo is something I'm still getting used to. Thank you for bearing with me and helping.

Error-50150 occured at DAQmx Write

Hello,
I am experiencing a seemingly random error in a large program. The error occurs in a part of the program that simulates tach signals to a CPLD. I have not been able to find out what conditions cause this error, it seems to be random in nature.
The full error reads this:
Error - 50150 occurred at DAQmx Write(Digital 1D U16 1Chan Nsamp).vi
Possible Reasons:
The software has entered an unknown state-usually as a result of a cascade failure induced by an unexpected series of state inputs. The operation could not be completed as specified and you should immediately terminate all further transactions if you are able to do so.
Task Name:TackABC_Write Port0 U16
The device we are using is a PCI-DIO-32HS, with Labview 7.1, NI-MAX 4.1, and DAQmx drivers 8.3.1. The task writes 3 signals to the CPLD, and it works most of the time, but every so often this error will occur. I was wondering what could be the cause of an error like this?
Thanks, Steve

Hello Brian, thanks for the response.
I made a mistake in my last post, it is actually a DAQmx clear task in place of the stop task vi i mentioned. When we first received this error it had no clear task at the end, but I added one. Even with this the error has still shown up from time to time. Would it help at all to add a reset device vi afte the clear task vi?
I took some screenshots for you as well. The first shot is of the function in question, the second is the same shot with the case turned to false, and the third is the inside of the main subvi. When the error occurs it focuses on the write vi that is inside the subvi. Let me know if there is more info I could grab that would make things mroe clear.
Thanks,
Steve

Error 7 occurred at ABAPI Dist Report Read Link Info Error.vi - [.....] - RTBUIP_Build_Invoke.vi.ProxyCaller

Hi all,
I am on a field campaign with my Labview-controlled instrument. I wanted to make a small change to the code and build it again for uploading to a cFP-2020 Fieldpoint but the application builder stopped with the following error message:
Error 7 occurred at ABAPI Dist Report Read Link Info Error.vi -> ABAPI Dist Cmp Settings to Disk Hier.vi -> ABAPI Get Settings From File2.vi -> ABAPI Get Settings From File.vi -> RTBEP_Invoke_Build_Engine.vi -> RTBUIP_Build_Invoke.vi -> RTBUIP_Build_Invoke.vi.ProxyCaller
This is another computer than the one I used in the lab previously so might have forgotten to install something. I just copied the whole application folder with project file and subfolders
to the Laptop I am using now. Labview version should be the same though (8.20).
Any suggestions?
Olaf

Hello Olaf,
This error is usually found when a subVI or a support file (DLL, custom control, etc)
isn't able to be found by the application builder. Possible reasons
for this could include subVIs no longer located in their original
paths and in need to be relinked, a DLL that isn't included in the build,
and many other possibilities.
You wrote that you copied the project from another PC, so it is very possible that some file went missing. Are all VIs in your project executable?
You could try to mass compile all the VIs in your project and see if that helps.

Error 7 occurred at Open File+.vipen File
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or
the file path might be incorrectly formatted for the operating system.

Hi Ravens Fan,
Thanks again for your valuable input. I replaced the string manipulation functions with a path control. I think it works coz I can see the waveform data, rms values etc. And then you said if it works, do a Path to String on that...and I'm not exactly sure how to do that. I attached a snippet of the modified vi. you may refer the original vi snippet in my previous email.
I appreciate it if you could help me again.

NI 845x USB: Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi

Hello,
I am currently working with digital accelerometer LIS35DE from ST Microelectronics. I want to start with tests of this device. For that purpose I used NI 845x USB to connect with accelerometer via I2C. Unfortunately, when I made electrical connections and set up parameters of communication and run the program (I found it in examples) the following error occured:
Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi
Possible reason(s):
NI-845x: An input parameter, or combination of parameters, is invalid. An example of this error may be setting an invalid baud rate or enabling I2C ACK polling while using 10-bit addressing.
The code can be found in attachements. I couldn't find any extended description of this problem. What could be a problem: incorrect device address, register address, configuration parameters?
Any help is appreciated!
Best regards,
Michael

General I2C Read.vi ‏24 KB

Hi MicMac89!
First of all could you please post which version of LabView are you using?
Could you please tell me which version of 845X hw are you using? (8451 or 8452)
I opened the example you attached. As you wrote the error occurs at the second argument of the property node. (I guess this is the first property node where the error occurs.)
This argument of the property node enables the onboard pull-up resistors. But not all NI-845x hardware support pull-up resistors. (Because of this is important to know which hw version are you using.)
Did you try the example with disabling the pull-up resistors?
I suggest you to go through the Manual of this product, (if you did this not yet) This could make it clear where and when to use what kind of pull-up resistors.
For example: If you are using 8452, you must enable pull-up resistors, for Vref ≤ 1.8 V for the FPGA to properly detect a low-to-high transition
Manual: http://www.ni.com/pdf/manuals/371746d.pdf
HW specification: http://www.ni.com/pdf/manuals/290598a.pdf
Please post if my suggestions helped. Of course if you have any questions, don't hesitate to post them.

Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi

Hey there,
we have sensors on an Engine which are connected to a NI cRIO 9014 board (with a NI9411 6-channel digital input modul) and go from there via network to a host computer.
cRIO board: the cRIO board collects the data from the engine and stores it in a buffer, this is because the network is to slow for the magnitude of data
host computer: the host computer reads over the network the buffer on the cRIO board, on the host computer it takes out specific portions of the data to create pressure graphs of the engine
Error:
Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi
Possible reason(s):
The transfer did not complete within the timeout period or within the specified number of retries.
This error occurs in the following scenario:
- engine is running
- cRIO is running
When I press the start button (boolean 3) in the host.VI to start the reading of the data from the board AFTER I pressed the run button of the host VI.
The Error would not occur if I pressed the start button (boolean 3) BEFORE I pressed the run button of the host VI.
We tried to increase the time out, but it still did not work, the error occurs!
We would be really happy if you could look over it and help us in this case! If you need further informations or if we need to clarify some specific portion, please let us know!
We included the VI's in the attachement!
Thanks in advance!

Chrisse,
There are a few things wrong in your application, if I may offer some suggestions.
First, your while loops are not running in parallel. In fact, they are in while loops with a true constant wired to them. I am not sure if this is by design for debugging, or on accident. I would put the Polling(read pulling zero elements) outside your main while loop.
Your second nested while loop (the one polling the # of elements and then pulling them out) is going to run just once, and may pull only a few samples. I don't think that is what you are looking for here, and there are a couple ways we can go here. You could continuously poll until you have 0 elements available for x amount of time, then you know you have no more samples available and you can process all the data OR you can put all of your data processing as part of that loop and just always write to file immediately as x samples are pulled.
Also, your main loop's stop condition is (i <= 3) Therefore, it will run once and then stop. Maybe you mean >=3?
Also, you have 'append to file' disabled on your write to spreadsheet, so everytime you write you are overwriting old data. If you want to continuously write, you will be losing data. This can be cured by either setting this to true(requiring a new file name or programatically deleting the old spreadsheet every time you run the vi) OR you can collect all of your data in a shift register, and only write to file once you have all your data available.
The error you are seeing is because you try to close your FPGA reference twice. You only need to close it once.
After seeing your overall picture, I think this can all be cured by simply hardwiring your Read to get your 1440X4 elements, but as we have seen, this does not work. Something is happening in your system....this is what I want you to do...run just the following code...and let me know how many elements remaining it gives you...Once the number has settled(I hope it does and your engine doesn't keep running), hit stop, and all the values will be put on a graph for you. My broken wires are because I do not have the FPGA VI.

Error 33172 occurred at Read & Write data transfer between two or more PF2010 controller

Hi,i need to do data transfer between two or more FP2010 controller.e.g. FP2010(A) & FP2010(B).
FP2010(A) need to transfer the measurement (from its I/O module) to FP2010(B) to do the data analysis.These data transfer should be synchronous btw two controller to prevent data lost.
From the vi used in the attachment,i encountered some problems at:
(1) Error 33172 occurred while publishing the data.Can i create and publish data under different item name?
(2) How to synchronies the read & write btw contorller?
All controller are communicating with each other directly without the need of a host computer to link them together
Is there any other method to do fast data transfer betwe
en controller?

Hi YongNei,
You were succesful in omiting enough information to make it very difficult to answer!
Please post your example.
Please tell us what version of LV-RT you are using.
Please define what you concider "fast data transfer".
Have you concidered mapping the FP tags of FP2010(A) to FP2010(B) and vise versa?
WHat exactly has to be syncronized?
If you have something that is close to working, share that.
Well, that as far as I can go with the info you have provided. Depending on the details, what you are asking could be anything from trivial to impossible with the currently available technology. I just can't say.
It would probably be a good idea to start over with a fresh question (sorry) because not many people are going to know what a a "
PF2010" is and I can not guarentee that I will be able to get back to you personally until next week-end.
Trying to help you get an answer,
