Unknown signal at start of signal generation

Hi,
I'm working on a system to generate a sine wave to a hydraulic actuator, and then measure the displacement at various frequencies.
The problem I'm having is that Labview seems to be generating about 10 seconds worth of data that it has not been told to before it starts to generate the sine wave signal I want to produce from when I start to run it.
I've attached the VI and a screenshot on the unknown signal. If anyone could suggest where this is coming from I would be very grateful.
Many thanks,
Ian

You should look up the term Dataflow, this is the main source of your error.., do a search on this forum and you will find many examples
You can also try searching this site and google for LabVIEW tutorials. Here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

When using the LabVIEW Simulation Module, how can I start a frequency sweep with the Simulation Chirp signal generation VI at an arbitrary time after the simulation initial time?

I'm using the Simulation Loop on LV RT when interacting with some hardware (i.e. all I/O is happening in the Sim loop). I'm going to conduct a frequency sweep test on the hardware and want to use the Simulation Chirp function. However, there is no way (that I can see) to trigger the Chirp to start at some event (i.e. I click a boolean on the front panel and enter a case statement). The Chirp is tied to the global time of the Simulation loop and so are it's input parameters. Is there a way to make it relative to some time at which an event happens?

Craig,
Your solution will 'cut' the beginning of the signal and only show the signal afterwards.
To control when the chirp should start, the best option is to use the Chirp Pattern.vi ( in the Signal Generation palette) and use a Lookup table to control when to feed the time. The shipping example (in LabVIEW 2013) shows how to code using a lookup table.
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Simulation\Signal Generation\SimEx Chirp.vi
Then, to start from a toggled boolean, look at the example:
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Simulation\Signal Generation\SimEx Step.vi
and Here is the example in 2013 (in attachment):

Signal Generation through pt by pt Signal

Hello,
I am acquiring signal through serial port, to analyze the signal, i am using pt bt pt signal analysis.
In order to work on it, i used sine wave pt pt signal generation. But remained un successful in generating sine wave through it.
Kindly guide me how could i generate sine wave using pt by pt.
Thanks

Hi Intelligent,
it's not a good idea to start asking by using PNs, I will ignore them in the future!
You wrote:
I already read the help and tried to solve the issue but after not receiving the satisfied results, i posted on the group. As its written in the help that the frequency is in Hz, but the value you have selected for the frequency is 0.01. So its un understandable, also the dependentence of time factor.
- What are "unsatisfying results"?
- Yes, the frequency is given in Hz and I chose 0.01Hz for sake of showing an example...
- "Dependence of time factor" is explained in the context help. Did you really read the help? Or do you have problems to understand the simple math formula provided in the help? All the parameters of SineWavePtByPt are used in that formula...

*Jul 9 22:29:34.791: Unknown signaling debug message (ch=0):

They start right after I reload and say no.

These errors are caused by the following bug -
CSCsk44000

channel ch=x is ON causes fxs port fail
This is resolved in 12.4(11)XW4 and higher.

Digital signal generation in cDAQ- 9477 with 1ms resolution.

I am using cDAQ -9477 Digital card with 9178 chassis (USB) .I have to generate some digital signals for 2 seconds. The signal should be
0 (3ms) - 1(1ms) - 1 (2ms) & repeat the sample 0 (3ms) - 1(1ms) ……. upto 2 seconds.
I had generated samples for 2seconds with 1ms duration of each sample.
I am unable to do that with 1ms resolution in cDAQ -9477 Digital card.
Is the above signal generation is possible (each sample -1ms) ?
I am using LabVIEW2009 .I attached the code.
Kindly let me know the suggestions .

cDAQ chassis do not currently support hardware timed tasks for digital modules with >8 lines. The DAQmx help defines these devices as "static digital I/O modules". The "Digital I/O Consideration for C Series Devices" section in the DAQmx help describes the capabilities of digital modules on different chassis.
Unfortunately this means you are stuck with static (software timed) generation. Over USB this will affect the accuracy of your signal. You won't be able to achieve the signal you are trying to generate with the current support. Static generation will max out at roughly 1kHz, but Windows can introduce a large amount of jitter. What you really need is a hardware timed task.
This is a feature that could be added in the future. I recommend submitting a feature request, though I know that doesn't solve your problem now.

Segment signal generation

Hi!
How is it possible to generate such a signal (picture attached)?

Many thanks. I did it using Ramp pattern VI and for loop.
The result is attached.
Now I need to sent this result to control and simulation loop.
This signal have to be desired position of my actuator insted of Knob (now I set the desired position using knob). check the attached vi.
But as I found out it is impossible to put 'for loop' inside of 'control and simulation loop'.
'control and simulation loop' also do not want to read updated signal from the outside, if I place my signal generation (using Ramp pattern VI and for loop) outside of 'control and simulation loop'.
Coul you please suggest somth?
THANKS

The field "SOURCE_PACKAGE" is unknown IN THE START ROUTINE?

Hi all,
i am trying to create a start routine in the DTP FROM THE CUBE TO THE OPEN HUB.
But when i check the syntax : it throws me an error message stating.
The field "SOURCE_PACKAGE" is unknown IN THE START ROUTINE?
how come the source package is unknow in the start routine can anyone pls advise me on this!!
DATA: l_tabix TYPE sy-tabix, wa_source_package TYPE tys_sc_1.
LOOP AT SOURCE_PACKAGE INTO wa_source_package.
l_tabix = sy-tabix.
IF wa_source_package-SALES EMP EQ ' '.
DELETE SOURCE_PACKAGE
WHERE SALESEMP EQ ' '.
INDEX l_tabix.
ENDIF.
ENDLOOP.

Hi Pooja,
I think that the error comes from the delete statement.
As you already said, the SOURCE_PACKAGE is from BI7.0. That means that the LOOP AT statement cannot be wrong (although I prefer field-symbols)
I would restate you code like below:
DATA: l_tabix TYPE sy-tabix,
      wa_source_package TYPE _ty_s_sc_1.
LOOP AT SOURCE_PACKAGE ASSIGNING <source_fields>.     "<source_fields> is declared as line from source_package
* l_tabix = sy-tabix.
IF <source_fields>-SALES_EMP IS INITIAL.
    DELETE <source_fields> FROM SOURCE_PACKAGE.
* If this line does not work, try to add TABLE after the FROM-statement
*WHERE SALESEMP EQ ' '.
*INDEX l_tabix.
ENDIF.
ENDLOOP.
Hopefully this will help.
Alternatively you can try a single statement, because it is not necessary to do a loop.
DELETE SOURCE_PACKAGE WHERE sales_emp IS INITIAL.
Good luck!

it says , j2EE is trying to come up but some how dying during the startup. looks like memory exhaustion.
what's the status of dispatcher, is it also down aswell. please provide dev_server0 log

How to trigger temperature acquisition (6024E) at the start of signal generation from NI5411?

I'd like to begin/end acquiring temperature data with the 6024E after the start/stop of the signal output from the 5411. What is the best way to accomplish this? is software or hardware triggering better?

Rudy,
Using a hardware trigger is definitely the more precise method. I would suggest that you consider using markers from the NI 5411 to trigger the NI 6024E. Information concerning this topic is available in the NI Signal Generators Help. Specifically, it is available in the following location:
Contents >> NI Signal Generators Help >> Devices >> NI 5411 >> Waveform Generation >> Marker Events
If you do not have the NI Signal Generators Help, it can be downloaded from the following location:
NI Signal Generators Help (NI 5401/5404/5411/5421/5431)
Once you have exported the appropriate makers, numerous examp
le programs exist that demonstrate how to trigger the NI 6024E. If you are using LabVIEW, I would suggest that you examine the Acquire N Scans Digital Trig.vi example.
Good luck with your application.

DAQmx with signal generation

Hello,
I am working on converting my current test code that used Traditional DAQ to DAQmx. I need some help with DAQ Waveform Generation.
In my current code I am using the Traditional DAQ to send a Sinewave output on on the DAC0Out on my PCI-6036E card. I have it set-up so I can runt he VI and when the Vi stops the Signal Keeps going until I tell it to stop. I need to do the same thing with DAQmx. I found that the example 'Cont Gen Voltage WFM-INT Clk-Variable Rate.vi does everything I need but when the VI stops so does my signal. What can I do to make it so the signal stays running when my vi stops.
this VI is a Sub in my program, the user is able to control a boolean to start and stop the waveform, I cannot keep it in a loop as they may want to turn ont he waveform and perform other tasks then turn it off.
I am trying different things as well, but any help would be appreciated.
Oh yeah, this is an XP machine running LabVIEW 8

Hello Jeff,
To continue to output a signal after you have stopped and closed the VI, you use the auto cleanup terminal on the DAQmx Create Channel VI. Auto cleanup specifies if LabVIEW automatically destroys the
task when the application completes execution. If auto cleanup is FALSE, LabVIEW does not automatically destroy the task until you exit
LabVIEW. But you can use the DAQmx Clear Task VI to manually
destroy the task.
I'm attaching a modified version of the Cont Gen Voltage WFM-INT Clk-Variable Rate.vi that continuous to generate the AO signal until you close LV.
Good luck!

I have a problem with a vi that crash and stops the signal generation.

I want to control several pumps and valve at the same time. Three of them are comanded by a board installed in other computer, so that I have to comunicate with them by a TCP/IP comunication. The others one are controled by signals sent by a PCI-6024 E board which is installed in my computer. The problem is that I want to create a vi that controls every equipment at the same time. I did a Vi that is in attach, but the problem is that when I run the vi it works during a certain time, but after 10 minutes (more or less) it stops to send the signals to the pumps. Could someone help me?

You did not include your subVIs so not much can be inferred. Several points of poor programming jump out
1. Use time delays in your loops to keep them from racing
2. Put the Open Application Ref and Open VI Ref before the start of the loop and the Close Ref after the loop

DIGITAL SIGNAL GENERATION

Hi!
I want to generate a digital signal (0-5V) in order to turn on and off an hydraulic pump. The time on (high) and time off (low) are specified by a MatLab code, so that once the pulse has finished one cycle, the program should be go again to MatLab code and take two times again. Then it should generate the signal again.
Thank you for the help.
Miguel

Thanks for the reply.
I have a system with an hydraulic pump, power supply, transistor and computer. I would like to send a digital pulse from my computer (0-5V) to the transistor. The transistor then closes a circuit (power supply and pump), and the pump starts running.
Then, I would like that each sample (each pulse) has specific width (time on), and also specific time off before it starts with other sample. These times (time on and time off) are computed by a MatLab code.
I'm working with DAQmx drivers and I also have a BNC 2110.
I also attach my code in Labview that I am trying to modify.
Thanks a lot.
Regards,
Miguel
