5122 and continuous triggered acquisition
I have a PCI-1522 and I want to do a continuous synchronous acquisition and have tried a number of things in NI-SCOPE without success. The signal I want to acquire is triggered (or to be more technically correct is synchronous with a second external signal) at 10 or 20 kHz and I want to sample at about 20 MS/s. Setting up the ext trigger is fairly straightforward if you put the initiate and fetch within a while loop. But then you have to loop on each trigger every 100 us (which the software is not fast enough to do even without the decimated processing I want to do) or acquire a larger chunk of data. This latter approach essentially initiates on one trigger pulse but acquires a large number (2M) of samples at 20 MS/s and therefore is subject to jitter if the samples acquired aren't exactly right. (I adjusted the sample size to correct within one sample and there is still persistent jitter so without triggering the accuracy required is less than one sample.) Bottom line is you aren't synchronous with either approach. With the fetch forever example, you move the initiate outside of the while loop which is great. But you have to use a software trigger in order to get it to work. All of the possible solutions essentially boil down to software triggering. I suffer either from jitter or drift.
I thought about using the video ref triggering schemes but then I have to configure my signal to fit into the pre-defined video formats which may not be possible. I haven't thought too much about a DAQmx solution. Are there any examples or solutions of a hardware-synchronous, continuous acquisition in NI-SCOPE or DAQmx?
Hi Dan,
You might want to take a look at the niScope EX Multi Record Fetch More Than Available Memory.vi shipping example. With this VI you can set up a multirecord acquisition and fetch records as they are being acquired. This allows you to acquire more records than will fit in the onboard memory. Currently, there are limitations in the driver which limit you to fetching about 2,000 to 3,000 records per second, so you will not be able to keep up with your 10 to 20 kHz trigger signal indefinitely. However, we are currently working on fetching optimizations which should bring this number up to the 10 kHz range in the future. We hope to release these optimizations in Q1 of 2007.
I hope this helps.

Real-time PID control and continuous buffered acquisition. Does it work together?
I use the "real-time PID control.vi" that acquires single AI point and generate single AO point in every "while loop" iteration to control a piezo actuator motion. Simultaneously I need to do (in another loop) a continuous buffered acquisition of another two AI channels (in the same rate as first AI channel).
It does not work together.
Does anybody know how to fix it?
Platform: LabVIEW 6.1
Board: PCI-6024EHi,
I would try to avoid the idea of using a separate loop since the PID
loop is a continuous acquisition and will require un-interrupted access
to the Analog DAQ system of the board. The last thing it needs is for
you to attempt to start other AI functions at the same time.
Configure your AI in the PID loop to read in multiple channels (Just add
some more channels to the Input Channels Control. Separate the data as
it comes out of the AI single Scan function using Index Array or other
Array functions into that needed for the PID and that needed for your
other data (the example is already doing this to make sure it only gets
1 channel of data into the PID). If you don't need to sample all your
channels of data all the time you can throw some data away as
required.
Obviously your other channels are now arriving one sample at a time so
if you might need to build an array, insert into an array or use Auto
Index on the loop if you are data logging.

Dave R.

6115 and post-triggered acquisition
I would like to use the 6115 card to sample an analog input at 6.4 MHz. It appears as if I should use the typical post-triggered acquisition mode as shown in Figure 4-10 of the 6115 manual. Therefore, I am planning on routing my 6.4 MHz sample clock to the STARTSCAN input of the 6115.
I would like to possibly use an internal CONVERT* signal. My question is, what is the delay between my STARTSCAN rising edge and the actual A/D conversion? Also, is the STARTSCAN pin the best way to sample the input? Is there a better way? Do I need to use the actual CONVERT* input?Hello;
There are two main ways of doing that. You can have your external signal routed to the StartScan pin, and that will control the start of a new scan. When a new scan is started, the internal counter that generates the Convert* signal is triggered. That method will take at least 10n seconds delay after you have the StartScan signal coming in, so the ADC will do one convertion.
The other way is to have the external signal tyed straigh to the Convert* pin. With that method, as soon as the external signal comes is, the ADC do one convertion, without any delay.
Hope this helps.

Continuous data acquisition using NiDAQmx with a start and a stop trigger
I'm sorry if this has been answered many times before, I can't quite seem to find the answer I'm looking for.
I am using LabWindows CVI version 7 and NiDAQmx with a PCI6023E.
I wish to acquire data continuously using an external clock as a timebase - I am happy with this.
I wish the acquisition to start when an external signal (say on PFI7) goes high. I am also happy with this.
What I also need is for the acquisition to stop when the signal on PFI7 goes low, or possibly when a signal on say PFI8 goes high. I'm not too concerned about which approach to use.
How do I stop the acquisition with an external signal?
Thanks in advance,
CrispieI don't have CVI installed, but I've attached screen shots of a LabVIEW program that I believe accomplishes what you are trying to do. Translating it to the C API should be straight forward. I'll try to explain what the program is doing since it's using some of the more advanced features of the driver. Also, the DAQ device you are using doesn't support a true "stop" trigger so I'm using a reference trigger to get as close to the desired functionality as possible.
First, the program configures a finite acquisition that uses both a start trigger and a reference trigger. The acquisition is using an external sample clock and will acquire 4 samples (2 pre-trigger samples and 2 post-trigger samples). Four may seem like an odd number here, but it allows us to emulate the functionality of a stop trigger as close as possible. Given this configuration, you must acquire at least 2 samples before the "stop" trigger is recognized, and you must acquire 2 more samples after the "stop" trigger is recognized. Hopefully this restriction is acceptable. You can always discard the last two data points after the stop trigger if they're not of interest, but you're stuck always acquiring at least two points between when the start and stop triggers are recognized.
The program also overrides the default buffer size and read position. By default, the DAQmx driver will pick a buffer size exactly big enough to fit the pre-trigger and post-trigger data (4 samples in this case) and will begin reading data from the start of the pre-trigger data. Explicitly allocating a larger buffer will allow your acquisition to execute without receiving buffer overflow errors, and changing the default read position will allow you to read all of the data between the start and stop triggers as it is acquired and not just the pre-trigger and post-trigger data.
Finally, the while loop takes care of reading the data. In this case, the loop continues to read data until the task is done and there are no longer samples available for reading from the buffer. The number of samples read per iteration is the lesser of the user specified amount or the number of samples available for reading from the buffer.
I hope this helps. Good luck.

Triggered and continuous analog input togeather?
Hi,
I have a program set up based off a shipped LV example involving digital triggering of the analog inputs. It looks at a pulse and reads in ten points from the rising edge continuously. It appears that we are missing some pulse triggers and only reading in 126 triggers/sec instead of 128. We double checked the pulse and the frequency is correct (128Hz) so it seems as if the LV program is missing some of the pulses. Therefore, I want to use another analog input channel on the same 6062E daq card to continuously read in the waveform and see which pulses are being skipped. Is this possible?Lisa,
I don't believe the E-series architecture will allow triggered and continuous analog input operations to occur in parallel. It is possible to set up different gains/input ranges but I'm 95% sure that the functionality that you are after isn't there.
If you are looking to keep track of the number of pulse seen by your application you could consider the use of a counter to count the number of rising edges seen by the NI 6062E - basically daisy chain the pulse train to the trigger input and the GP_CTR Source pin of the counter you wish to use. There are a number of examples around that should help with this. Running the counter and analog input operations in parallel shouldn't be a big problem - it might be that you would want to set up a buffered event co
unt operation for the counter as this will allow you to track and monitor every single trigger event seen by the counter while your analog input operations continue in parallel.
The other aspect to consider is benchmarking your application with the Profiler. If the problem is that you consistently only see 126 triggers/second, perhaps your acquisition loop is not running fast enough to cope with the data. This can be especially true if any data processing or file storage is taking place inside the acquisition loop. The Profiler will allow you spot bottlenecks and get a better understanding as to the performance of your application.
I appreciate this is perhaps not a direct answer but hope that it gives some ideas as to how to track down the cause of the problems you are experiencing.

Hi all,
I need to do high-frequency, high-channel-count acquisition.
Specs
Signals: 10 MHz, 60 channels
Controller: PXIe-8135 (Windows 7)
Chasses: PXIe-1085 (2x)
Input cards: PXIe-7962R FlexRIO base with NI-5734 digitizer (15x)
Description
Each FlexRIO card will store data in circular buffers, and continuously monitor the voltage levels. When any one channel exceeds the user-defined threshold, all 60 channels need to be triggered simultaneously to pass waveform data (200 μs pre-trigger, 300 μs post-trigger) to the host OS for logging.
In other words, every FlexRIO card needs the ability to fire the trigger, which is then received by all 15 FlexRIO cards (the card that fires the trigger also needs to receive the trigger).
Question
Can I achieve this with only a single PFI line? Or do I need some other technique?
I've found some examples, but they only show single-source and single-card triggering, e.g. https://decibel.ni.com/content/docs/DOC-30182 uses one analogue input to trigger the acquisition of 2 channels on the same card.
Any advice would be much appreciated. Thanks!Assuming you are using LV 2013 or 2014 you should download version 1.3.4 of the FlexRIO Instrument Development Library (FIDL). This will install 5734 Acquisition Engine examples which use the MultiRecord Library to stream data to the DRAM in a circular buffer, allowing you to recover pre-trigger samples. The example also demonstrate how to implement the Syncrhonization Library that synchronizes triggered acquisition to within a single sample period across multiple devices.
Getting the example to work across two chassis' may be difficult, but I believe it is possible. Though to do so you will need a timing and sync module in each chassis to distribute the triggers and reference clock that the sycnrhonization library requires.

Hardware digital trigger to start stop continuous analog acquisition
Hi I have seen the following example to use digital trigger to start and stop for finite number of samples. The example names is (DigitalStartandStopTrigger.vi)
in this example Reference Digital edge is used to stop acquisition but if I change to continuous then Reference Digital edge stops and show an errir. Could you please let me know how can I use hardware digital trigger to start stop continuous analog acquisition. An example would be really great
many thanksHI tintin_99,
The way that example works (by modifying the read position of the buffer) essentially performs the same operation that the continuous samples mode does. That is to say, it is already a continuous acquisition.
The article below explains this in more detail, and the reasoning behind specifying buffer size manually and other tricks used. You may have already visited it in order to get the example VI, in which case it may be worth another read over.

Multi channel continuous DAQ acquisition
Complete newbie question here. First time using Labview so I apologize for asking this question: Is it possible to have multi channel contiuous acquisition? If so, does this have to go through a circular buffer to prevent tying up all the computer memory? Can you vary the scan and read rates for each channel? Last question: If it is possible to do all of the above....how do you do it? I've attached a .pdf file with screen shots of my front panel and block diagram....it's extremely crude just trying to get some basic concepts down. Also if anyone can recommend some good books on actually doing the wiring and conditions of the various elements, I'd be extremely grateful. Currently I have "Labview for Everyone".

DAQ.pdf 33 KBHello,
It is possible to have a multi channel continuous acquisition and it does use a circular buffer. Please check out the Continuous Waveform Acquisition Tutorial for more information about how this is done. With our DAQ devices you can use different sampling frequencies as long as they have a common divisor and the sampling rates remain within the device specifications. There is an example of that called Multi-Rate Continuous Analog Input.
The example finder is always a useful place to look for ideas on how to make a VI. In LabVIEW, go to Help->Find Examples and you will open up a browser that will allow you to look through many examples. You can also check out the LabVIEW Zone Learning Center where you can find a book listing under the fundamentals section.
Hope this helps!

Place Call and continue with remaining script steps - is it possible?
We recently picked up IPCelerate which has the ability to send a Text display or Text-to-Speech message to a group of phones simply by dialing a configured directory number. We would like to text our call center agents with this application when a caller has been waiting for X number of loops.
Attempting to use 'Place Call' to initiate this text page works, however, the script terminates immediately after the call is placed and we would like to continue on with the remainder of our script. In this case, on Success go back to the top of the loop.
I have also tried to use Call Subflow instead, thinking an executed sub-routine placing the call would return to the original script and continue on, but it didn't. In both cases, the system comes back and states " I'm sorry, we're currently experiencing system problems and are unable to process your call. Please try again later."
If there's a way to get this to work via Place Call or another process to accomplish the same result, that would be fantastic. I appreciate any feedback.
We're using UCCx Express 5.0 (2.064) with premium type licensing.Hello,
I did get to an answer similar to what r.stockton did to solve the issue, but I left Exception (ContactInactiveException) Goto in ours to isolate exceptions because we have multiple contacts within our script. Turns out that this particular exception was thrown by the PlaceCall step ending abruptly by our paging system answering and hanging up the call quickly. MIVR logs showed that it didn't bomb as immediately as when the debugs showed it crashing - it actually went into a loop over and over with the Trigger contact before failing.
We had some help from TAC on this, but below is what we did to keep some error checking and notification we use available to us. We are running a check to make sure the Call Trigger (original call) is still active.
placecallContact = Place Call (to Number)
on Exception (ContactInactiveException) Goto
label:
CallActive = Get Contact Info (--Trigering Contact--, Active)
If (CallActive) Then
- True branch continues with script
- False Branch terminates call
If this takes the false branch, it means the trigger contact is not active, and has abandoned the call or been transferred elsewhere. Placed an End step here to prevent any loops.
If this takes the true branch, it means the triggering contact is actually still active. In our scenario, CallActive (boolean variable) is verified true and continues with the script without going into the loop of death.
I hope this helps! -
Continuous, triggered, high-speed motion capture
Hello,
I'm attempting to perform a continuous triggered high speed motion capture independent of the motion, and it's not clear that this is possible. Before I spend a few hours on a wild goose chase, I thought I'd ask around.
I have a digital pulse train coming in at about 100 Hz and I'd like to measure the position of my motion system in all 3 axes at each pulse. Having acquired the data, it should then get dumped to a file. This should happend continuously until the user exits the program. The continuous part of this seems unnecessarily complicated, involving on-board programming, if my reading of examples such as onboard-hsi-gpbuffer.vi and continuous_hsc.vi is correct. However, if that's the worst of it, I'll survive.
Meanwhile, the system is undergoing random motion, including starting and stopping of the axes. This is the part that has me particularly concerned. All of the examples that I have seen, both bundled and otherwise, seem to include a single move as part of the program. Since my system will be undergoing multiple moves controlled by the user, I'm concerned that these moves (or the end of the moves) will cancel the capture operations.
Does anyone have any insight into this sort of setup?
Thanks,
JasonThis seems to do the trick. It's based on the "Onboard Program - Continuous High Speed Capture into General Purpose Buffer" which can be found in the online examples. It implements an on-board program which fills a general purpose buffer. Most importantly, it runs continuously and independent of the motion or stops of the various axes. Hope someone else finds it useful.
Still curious if this is really the easiest way to accomplish this.

What is the diff between Stop and Continue?
<b>STOP</b>
Effect
The statement STOP is only to be used in executable programs and in the following event blocks:
AT SELECTION-SCREEN (without additions)
START-OF-SELECTION
GET
You leave these event blocks via STOP, and the runtime environment triggers the event END-OF-SELECTION.
Note
The statement STOP is forbidden in methods and, since Release 6.10, leads to an uncatchable exception during the processing of screens called with CALL SCREEN and in programs not called with SUBMIT.
Example
Ending the event blocks GET sbook after max postings have been issued, and branching to END-OF-SELECTION.
<b>CONTINUE</b>
Effect
The CONTINUE statement can only be used in loops. If it is used, the current loop pass is ended immediately and the program flow is continued with the next loop pass.
Example
A loop pass is exited using CONTINUE if the loop index sy-index is an odd number.
DATA remainder TYPE i.
DO 20 TIMES.
remainder = sy-index MOD 2.
IF remainder <> 0.
CONTINUE.
ENDIF.
WRITE / sy-index.
ENDDO. -

I have an iPad2 and a new MacBook running Mountain Lion. Both Devices use the same Apple ID which is a Hotmail eMail id. Can I create a new iCloud eMail Id and use iCloud eMail and continue to use my current Hotmail Id for my Apple Id for iTunes, iCloud.
Note, I will use both Hotmail and iCloud eMail.Welcome to the Apple Community.
In order to change your Apple ID or password for your iCloud account on your iOS device, you need to delete the account from your iOS device first, then add it back using your updated details. (Settings > iCloud, scroll down and hit "Delete Account") -

I can't shut down my computer because it says mail is open. It says to close mail and continue shut down. Problem is I can't open or close mail now. Can't shut down my computer at all. What can I do?
If you cannot get mail to quit/force quit, you can always remove power from your Mac.
NOTE: removing power is a bad idea, and can result in data loss, but sometimes it is the only thing left to do.
Press and hold the power button for 5 to 10 seconds, and the Mac will power off.
When you power back on, the Mac should reboot.
