• False values of voltage using NI 9225 and ELectrical Power Suite 2014

  Hi all

  I have a few problems regarding the use of a map of analog voltage NI 9225 with code exaple quality Applications of power (cRIO) (Delta-Sigma) of the Electrical Power after 2014. Running the example code I values of voltage wrong, they are exactly doubled! For exaple with a 230 V RMS input I get 460 V RMS. I think the problem is the module, because by default, the code example expects to use a module NI 9242. Before the upgrade to LabView 2014, everything worked perfectly with EPS 2013. Am I something missung? I configured the C module in the project manager in the same way that I used with EPS 2013. Can someone help me? Thank you

  Hi Gianluca,

  If you use other types of modules in the example, you must take care of the conversion of accuracy in the FPGA VI.

  As FPGA VI resampling takes the signal of type fixed point +-24.1, you convert the +-24,10 and-24,5 to 24.1 in the Data Acquisition loop before feeding to the FPGA VI resampling.

  And in the loop of data Communication, you restore the output of +-32,3 to 32,12 - signal + and +-32.7. Notice at the time the zoom in and zoom out are equal.

  If you change other types of modules of different precision, you must change the precision of the given thread.

  For example, 9244 accuracy is +-24.11, so when you convert it to +-24.1, you must restore it by variation of-32,3 to-32,13.

  Please refer to the screenshot:

  

• NEITHER 9225 flow Acq

  Hello

  I have a NI 9225 in a cDAQ-9174 chassis.  I have the software to set a calendar of 1000 Hz sample clock, and then trigger a reminder once 1000 samples are acquired.  Acquisition mode is continuous.  The callback is triggered after 620 mSec. No error code is displayed.  Reminder should trigger at intervals of 1000 mSec.  Any suggestions?  My application depends on evey shooting 1000mSec recall.

  The software even when it is used with other devices such as USB-6215, USB-6008 or NI 9215 boxes works very well, fires reminder at regular intervals of 1000mSec.

  CVI 8.1.1 and DAQmx 9.2.2

  Thanks for the reply.  Tried today.  Works well with rates aacq 2000 Hz and 2000 sample between reminders.  Callback is triggered at interval of 1000 mSec.

• Module NI 9225

  Hello!

  I work through the module nor 9225. Can I use this method (photo or 9205) for the acquisition of data. This method I use when I I was working with module 9025.

  Is there any difference between the use of modules of 9205 or 9225 data acquisition? I know that neither 9225 is sigma-delta module.

  Kind regards

  Well, I would use the advantage of parallelism nativ you to the FPGA and sepparte in the two individual loops.

  You can then use Global Variables to pass data of loop to another where you transfer the data to the host using DMA FIFOs.

• How "block of surge protection" works in NOR-9225 and NOR-9227

  Hi all

  Hi, I use NI 9225 and NI 9227 to collect data under high voltage.

  According to the data sheet, the NI 9225 has protection against overvoltages and NI 9227 overcurrent protection.

  I wonder what kind of protections, they, I mean, if high voltage or current applied, what will happen to the material? Fuse has popped up? Or trip relay? Can I re - opening after the failure to tension?

  Thank you

  Jenny

  Hello Jenny,.

  We have an IC isolation that will protect some of the internal circuits. There is no fuse or relay you can replace. Because of this, if you exceed the specifications (±450 VDC for the RMS A 9225 and 5 / 10 A RMS for 1 s max with 19s cool time 5A RMS for the 9227), so will most likely damage your card. If you open the module, you will lose the warranty of your device.

• cDAQ-9174 with modules 9225 and 9239 for issue of power measurements...

  Hello to one and all.

  I do turn a cDAQ-9174 with modules 9225 and 9239 to measure the voltage (120, 208-240, 277 VAC) and current (via the clamp amp i400, Fluke - 10mA/exit A) respectively.

  I have the set scale scale Differential No. (1:1 I guess) for 100: 1 for current and voltage.  With the acquisition mode set to "N samples", 10 samples to read, at the rate of 500 m.  This feeds into 'EPM_Power.vi' (polymorphic VI of the palette of EMP... can be downloaded here, http://sine.ni.com/nips/cds/view/p/lang/en/nid/209826)

  I try to check my numbers with an Analyzer of power quality of 435 Fluke and supporting that upward is a Fluke 179 True RMS DMM with clamp amp i200 (for current playback)

  Now, I'm running is my numbers I take data look like they're following a curve of fishing... the averages are on the right, but when my blood pressure is expected to be relatively stable, it's over the map... same story with my current readings.  I tried several different filters without success.  I would like to have relatively stable values for voltage and current so my other values are correct.  Is there a signal conditioner or filter that will help with this?

  As always, a point in the right direction would be greatly appreciated!

  Thank you!

  Chad

  Hi, Will,

  Your request for a screenshot actuall lead me to the solution.  Not enough samples!  I took little data too slowly and only seeing part of the wave of fishing AC each iteration.  .. that became glaring when I tried to this graph.  So I increased my sampling of 100 to 5 Hz and things seem to have settled things down a bit.  Thank you for the good question!

• 9225 and 9227 Module Constant phase shift (Drift)

  Hello

  I wrote a large VI and the am acquisition voltage and current with the 9225 and 9227. The phase of the voltage and current constantly derivatives. Its not just for phase a bit for all of the portion; the phase constantly cycles from 0 to 360 degrees. I have an excel file with locations showing what I mean. Series 1 = voltage 2 = current

  I wrote a small VI to do the same thing with nothing extra. I have not yet add the data record. I just use a graph to plot the voltage and phase. The voltage and current were still off!

  What do you think. Timers are bad on the modules? Slow computer? DAQ assistants are not good? IM using the internal timers in the modules.

  Synronizing at the beginning does not help because the signals would still go out of phase when even later. The load is a piezoelectric tube.

  I'm using Labview 2011 and NEITHER cDAQ-9178:
  9225 3CH 300 Vrms 24 BIT simultaneous AIN
  9227 4CH 24-BIT simultaneous AIN 5Arms

  See you soon

  I forgot to change to continuous. I do usually. The major difficulty that I did was remove the trigger "Start Digital Edge" completely. The trigger wasn't working properly with what I put it in, "PFI0"... Once I took it out, I got a sample invaded. I played with the numbers of the sample for the clock sampling and playback. I don't know why to use 25000 everywhere has not worked. But when I dropped the numbers to 6250 or something of this magnitude, the VI finally worked.

  The VI works with or without the clock I specified (Mod7/AI/sampleclock), which is great news! Thanks for this tip!

  The current and voltage are finally in sync. They will never out of sync! Finally I can calculate the POWER!

  This digital trigger was the worst headache... Thanks for the tips!

  I write the VI and the code snippet to my completed solution.

  

• Safari cannot connect to the server, but other browsers can?

  Hi all

  I read a lot of posts on this issue but do not seem to share the same success or symptoms.

  I'm unable to access a domain www.ninnim.co.uk

  I can access it fine on my iPhone and Chrome.

  I can't access mode without failure or any other profiles created.

  I have not a firewall is enabled, and it is the only area in which I can't access. Of course, when I talk about godaddy they simply access via IE and it works fine, which puts an end to their participation in supporting me.

  Someone has ideas what could cause this and how can I do to put it right?

  In hopeful preparation, I have this information that has helped others in the past;

• Voltage wave are not smooth!

  Dear all

  I use power quality measurment with the cRIO-9023 + 9118 + 9225 + 9227 with LabVIEW and EPS 2013.

  My questionthat why the voltage dispay wave are not really smooth. Please please let me known the reason why and how can I make it smooth!

  Please see the picture below

  I thank and consider

  Luong.Tran

  Hi QuangLuong.Tran,

  1. perhaps this is what in fact generated from your singal source. You should try to use an oscilloscope to look for yourself.
  Be careful with the high voltage however.
  The top of the flattened wave can also suggest that the amplifier maximum has been reached. Try to reduce the amplitude of the wave and the measurement using the rest of the EPS.

  2 right-click on the plot icon and choose 'Smoothing' for a smoother view. See the attached screenshot.

• Cannot acquire with cDAQ in hardware mode timed using DIAdem DAC

  Hi all

  I use DIAdem DAC to acquire the cDAQ + 9225 + 9219. 9219 acquires the use of single point mode that works very well. However, I tried to acquire waveforms 50 kHz 9225 with the file attached dac. However, I found a problem on the block of the clock, as shown below.

  

  How could I solve this problem and gain the waveform with 9225 using DIAdem DAC?

  Sincerely, Kate

  Hello Kate,

  You must connect the NIDAQ-In1 exit the Save block block. In addition, you must change the parameters of the horloge1 block. The material is always measured in mode "DAC-kernel". "The software clock" is used for frequencies of up to 10 kHz clock (depending on the material and the PC). If you want to measure more quickly, you can use the "Clock" mode

• phase shifted PWM with Ni 9401 and Crio

  Hello

  Do you have an idea of pwm shifted 180 degrees?

  (duty cycle frequency and variable difficulty)

  I tried a design, but it seems in the graphics design works on the realtime.vi but it does not work with the fpga.

  Graphic output pwm FPGA are distinguished by the real time as you can see in the pictures.

  On the other hand, VI Fpga produce two pwm, as seen in the oscilloscope when the fpga VI runs.

  However, there is no phase shift between the PWM waves.
  It is a part of my thesis, but I'm stuck in this problem, so I need assistance on your part.

  Thank you.

  Yes I want to that they will be moved with the right variable and 10 kHz. I put 49% maximum duty.

  I put the output into the same output block.

  I have attached a simple FPGA project file. Could you please tell me what is my fault?

  The resulting Pwm frequency is 10 kHz, the only problem is always the shifters.

  The NI 9225 300 module input analog Vrms C Series has been designed for the waveform of signals measures high voltage. The Vrms 300 range allows line-neutral as a line of measures of electrical of 110 V and grids of the 240 line-neutral networks V. Three NI 9225 channels make the ideal module for a three-phase system. Measures voltage waveform are required to follow events like sag, swell, transient power quality and harmonics. Combine the 9225 OR with the NI 9239 (10 V) and a current transducer to create customizable power quality monitor or a power measurement system.

• cDAQ HAVE task using external clock

  Hi, I am trying to use a clock signal on a line of PFI in order to generate a clock, but at a lower rate, for a task to HAVE.  I run into many issues that I can't explain.

  I have a cDAQ-9172 with an entrance module analog (9225) in the Groove 3 and a digital input module (9411 - 2 MHz DI) into the slot 6 (where the PFI lines are accessible).  I want to use an external signal on et0/PFI0 to act as the clock for an analog input on the 9225 task.  This signal comes from the cDAQ anothr chassis and is too fast for the task to HAVE it, so I intend to use the time base entrance and the divider to clock (as shown on page 31 of the cDAQ-9172 manual).  See picture attached for a graphical representation of my problem.

  If I have the wiring from the signal "/ cDAQ2Mod6/PFI0" in the DAQmx timing VI, get the error 200414 saying that "required sample clock source is not valid."  It is strange because it is listed as "Direct route" in Max (the VI of polymorphic DAQmx Timing is configured as 'Sample clock') Q: why this route is not suitable for the task?

  If I use DAQmx Timing property node and change the Source 'Sample clock Timebase' to ' / cDAQ2Mod6/PFI0 ", the task starts without error, but the separation seems to be forced to 256.  If I try to change the properties of the separation of the time base, I get error-201100.  Try to change the 'sample clock rate"doesn't have any impact on the task and the remains of divider"256 ".  Q: why the 'Programmable clock divider"locked to 256 when using the PFI line or can you just not program directly?

  I came across another error is the minimum speed on the PFI line.  If I have the wiring (for the SamplClock Timebase) lower at 1 MHz, LabVIEW returns error-200077.  The error message indicates that the minimum value is 1 MHz.  9172 manual shows the clock 100 kHz is an option for the time base, certainly less than 1 MHz.  Q: What are the limits of upper and lower frequency for a clock signal on the line PFI for the ' Timebase AI/SampleClock "?

  I looked on the site and in the DAQmx documentation for further explanation, but I have been unable to explain these strange behaviors.  What are the barriers to entry of Timebase PFI and the time base "Programmable clock divider" preventing me to reach my goal here?  If I can't do it directly, can I use the PFIn signal to feed an internal counter (to act as the clock divider) which could then generate the clock WAS at the rate I want?  This method would allow me to perform a division arbitrary clock (unlike the ' 256', which seems to be forced on the PFI as a Timebase SampleClock.)

  Finally, something seems odd that I can make an acquisition to 10Sa/s max but when I start a task using an internal timers of the cDAQ9172 and ask a 10Sa/s rate, the task really gives me a rate of 1612.9 sample/s while using the 12.8 MHz clock and a divider 7936 timebase.  Q: Why can't the task to 10Sa/s?

  I use DAQmx 9.7.0 and LV2012 SP1 (and I tried with 9.7.5 but I got the same results)

  Thank you

  Olivier

  I got additional help Friday in another engineer at NEITHER and the solution to my original problem is actually very simple to get the clock from an external source path:

  

  The idea of picking a PFI line for the basis of 'time' and the 'Programmable clock divider"(in fact, DAQmx calculate this number based on"HAVE sample time clock"and"Sample clock HAVE") works by using the node property below:

  

  (SampleClock.Source cannot be resolved until the task is clerks/reserved, but the default option seems to be the time base that works well in this case.)

  The question that I described earlier with the 9225 comes the module properties and the fact that it is a "Module of Sigma - Delta".  That the module usually generates its own time of 12.8 MHz base clock (page 14 of the document 9225 # 374707) and the clock divisor is much less possible values than the other modules (must be a multiple of 256). It may use a different time basis from a PFI line, but it must be between 1 MHz and 13.15 MHz.

  So a main clock between two chassis and tasks running at different rates of sharing should be easy and simple with most of the modules.  With AI modules with Sigma-Delta converters add additional limitations and the master clock for the time base frequency must be selected to accommodate these module as well.

  Another good news is that the Simulator seems to bear all these details and DAQmx (9.7.0 in my case) generates the same errors when you use a simulated chassis if you use real body.  Play well!

• Filter low pass analog (anti-aliasing filter) external to the NI USB 6251 housing

  Hello everyone!

  -I m trying to acquire an analog signal of tension (high frequency content) using a connected to an edge NI USB-6251 BNC-2110. I learned in this Labview Forum that NI USB-6251 has no analog low-pass filter programmable (or anti-aliasing filter), so that I can't help but jitter when scanning my signals. For my application, the cutoff frequency of the analog low-pass filter must be equal to 100 kHz or MORE (maximum of 500 kHz). A possible solution to solve my problem, would be to work with an external analog low-pass filter before you scan the voltage signal. Based on this I'd like to know:

  (1) national Instruments develops analog external filters? I need a filter which also has one output, analog, so that I could send also the low-pass analog filter filtered signal to my NI USB-6251 box to scan correctly it!

  (2) what model of external low pass filter would be compatible with the NI USB-6251 housing?

  Any help would be much appreciated!

  Best regards!

  Hello

  all high resolution of the M series (628 x) cards are equipped with a filter low pass which can be enabled or disabled programmatically. For the anti-aliasing filter feature, examine the boards of National Instruments DSA (dynamic signals Acquisition) acoustic and vibration measurement
  currently the NOR 9221, 9225, 9227, 9229, 9233, 9234, 9235, 9236, 9239 and 9237 C Series modules feature anti-aliasing filters. These modules are intended for the high accuracy measures for which anti-aliasing filters are a necessity.
