• Delta PLC with single-phase inverter

  Hi all
  I have Delta DVP 20EXPLC. In this machine, we can generate output pulsed Y0 and Y1. I wish to make the single-phase inverter with the help of this dry vegetables. Now, I use four MOSFET that will operate the switches to reverse operations. Fundamental reversal operation is right there pair of transistors MOSFET only should be remnants or OFF. The problem for me is, when I give the pulse of the controller, the pulses of the MOSFET 4 are the same, it cannot work with the above format. So, I have no inverse sine.

  I hope you understand my condition. If it isn't enough, I'm willing to explain deep depending on the response. Please help me with this problem.

  OR if the opportunities are there to control the VI MOSFETs...?

  Hello

  Your application this MOSFET control requires only the digital output that can be transmitted using any protocol of industrial communication.

  I checked the information on Delta DVP EX and found it supports these protocols: Communication port: integrated RS-232 and RS-485, MODBUS ASCII-compatible / communication RTU pro....

  LabVIEW supports all the of them. You can find examples for the first two in LabVIEW help - find examples...

  You can download Modbus support since the product page of NOR.

• Configuration of the basic Source of time to master for the 9234

  I have several cDAQ modules I use to collect data.  I use vi to Write can Express to save data to a file of PDM.

  When you examine the recorded data files, the measured data from NI 9215 provide pleasant timestamps to match how the DAQmx task has been set up--delaying the sampling frequency of 1000 with a 1 ms in the While loop.  However, although in the same vi - different tasks, but the same while loop - horodateurs of the NI 9234 do not correspond to the task of DAQmx implemented - sampling frequency of 1000 with a 1ms delay. After reading the material provided with the NI 9234, I found that maybe the machine clean master Timebase Source. There were documents that says he can be configured to be originally of Timebase of Master for the other modules:

  Configuration of the basic Source of time of the master for the NI 9234 (Interface FPGA)

  It is desirable to have the timestamps for data measured across all modules to match. We do not have the FPGA Module for LabVIEW. Is there a method in LabVIEW for all modules use the same master time base Source?  I assumed that because all the data collection has place in the same while loop by using the time delay of 1 ms it was forced through the code. This hypothesis seems incorrect from my review of the PDM data files.

  The NI 9204 provides a trigger only.

  Hi MgDAQ,

  An important concept to note is that the 9234 uses a delta-sigma converter and a clock of oversampling to read analog data. There is an inherent delay of entry due to analog and digital filtering built-in. Since the 9215 has a lower resolution there will be a lag the 9234 and 9215 finished. I've included some resources below:

  What are the for the NI 9233, NI 9234, and NI 9237 valid sampling rates? : http://digital.ni.com/public.nsf/allkb/593CC07F76B1405A862570DE005F6836?OpenDocument

  Have you tried to put two modules in the same spot? Alternatively, you can export the sample clock 9234 and tasks installation separately.

• Single-phase controlled Rectifier

  Hi all

  I am simulating the single-phase controlled rectifier circuit with Multisim 10. But the wave of the oscilloscope was wrong. Can someone help me?

  You have a voltmeter with 10 megohms of internal resistance in series with the output so current can flow. Remove the voltmeter and the circuit works.

• I use an analog input on a PCI-6224 and are having problems with the clock source

  I use an analog input on a PCI-6224 and are having problems with the clock source. I'm trying samples of 16 different analog inputs very quickly. I have the sample mode: Timed Single Point material. The rate, that I am running is the maximum (250 kHz (15625Hz per channel)). I left the default clock source and trying to taste several times. The analogue input works for a short time (2-3 seconds) and then everything stops. I'm doing something wrong or is there something I'm missing? Any advice would be great.

  That's how you samples using the sample clock clock. If you see a delay then something is wrong with how you track/data visualization.

  Single point NI the hardware is for PID control with a real-time operating system.

• Wiring of the PXI-4132

  Hi all

  I would like to know how to wire the PXI-4132. You can check the links below specification.

  http://sine.NI.com/NIPs/CDs/view/p/lang/fr/NID/207349

  http://www.NI.com/PDF/manuals/375128a.PDF

  -My problem here is that I do not understand is that a terminal guard. (check the p5 on pdf)

  The output HI and LO match ups and downs (current or voltage) source, you need to source.

  The sense HI and LO correspond to the upper and lower (current or voltage) measurement, you need to measure.

  -How to the voltage source and to measure current?

  Seems to occur at the same time. That means output HI sense HI are connected to the same point and feel Lo and LO as well.

  -Is this someone obtain a wiring schematic of the PXI-4132?

  Thank you for reading and discussion

  Hello

  You can call screws of TestStand or use the DAQmx driver so I think that it should be possible to make this kind of measure using TestStand.

  Kind regards

• Can I use a NOR-9244 for measuring single-phase AC 2-wire 480V?

  As the 9244 module is rated for a maximum of 400 v L - N and L - L 800V, to measure 480V, I would need to connect to AI0 AI1 and let the neutral entry floating. Manual outlines all single phase measures referred to the input neutral and has some instructions on the conversion of L - N L - L measures, but it is expressed not bad so I don't know if it tells me that I can directly measure the voltage through AI0 AI1, or not.

  Can anyone confirm that I can make measurements with 9244 cable in this configuration, until I drop the $$$ to buy it?

  Hello MStewart,

  A distinction must be made between Vpk and Vrms.

  @GerdW is correct that the input device is ~ 1000Vpk (997.5Vpk). However, this translates into ~352.6 Vrms

  The side of 800 Vrms for line (L - L) measures is for multiphase applications.

  As you take a single-phase measure, you would use an AIx-neutral (L - N) connection.

  The diagram for this is detailed in figure 12 on page 25 of the Manual:

  <>http://www.NI.com/PDF/manuals/376131b.PDF >

  So to measure above 400Vrms on this unit, you will need to use a power supply external to resign from the tension, as mentioned in the white paper in (specifically the section of voltage):

  <>http://www.NI.com/white-paper/8198/en/ >

  In summary the 9244 cannot directly measure 480Vrms.  You can set before the signal to less than or equal to 400Vrms

  I hope this helps to clarify your question!

  See you soon,.

• WES7: 'Windows cannot access the installation sources. "Check that the installation sources are accessible and restart the installation.

  I try to install Windows Embedded Standard 7 on an vacuum Compact Flash 4 GB but when installing, I get an error message "Windows cannot access the installation sources. "Check that the installation sources are accessible, and run the Setup again."

  I created an answer file with the Configuration of Image Editor and I created an Image of the IBW of my answer file. All the files and the Image of the IBW (738 MB) files are copied to a USB bootable 4 GB. I inserted the Flash DRIVE to a computer with a Compact Flash 4 GB (which contains only a primary NTFS partition set as Active) and it starts on a USB key. IBW Wizard starts and I followed the instructions until the disk selection step. I chose the disk and partition of Compact Flash and I press the next button. First 2 installation steps manage (copy of Windows files and extend Windows files) but 3rd step (installing features and updates) failed with the error message "Windows cannot access the installation sources. Check that the installation sources are accessible, and run the Setup again.'.»

  I tried to do the same thing with a Compact Flash 4 GB, which contains 2 partitions: a primary NTFS defined as active and a system partition, but I got the same result. Then I tried to install it on a Compact Flash 8 GB which contains 1 single defined primary partition as active and I managed.

  Problem is that I must install on a Compact Flash 4 GB.

  Can someone help me please?

• MISSING OBJECTS IN THE IPHOTO SOURCE LIST

  1. lack of points of the iphoto source list such as: places, trash (I have all of the photos, last import, Favorites, videos).  How can I restore what is missing?

  2. under iphoto events are lists date of the photos.  However, the only ones that have a picture on the tile are in 2014.  I 2015 dates shown with a blank tile left and I have none for 2016.

  3. I have dropbox, but my photos are not synchronized with all my devices.  My iMac has all the photos, but each of them does not flow to my macbook.   There is partial proof of 2014 and 2015 photos in the macbook (so some transferred) and all to see the 2016.

  4. when I click on a photo I do not get the arrow pointing down to the context menu and I don't have an icon or anything to click for editing.  I can rotate.

  Help!  What is my problem?  Thank you!

  1. to begin, we need details - what version of the operating system and iPhoto do you use?

  2 - explain that statement in detail

  I have dropbox, but my photos are not synchronized with all my devices.  My iMac has all the photos, but each of them does not flow to my macbook.   There is partial proof of 2014 and 2015 photos in the macbook (so some transferred) and all to see the 2016.

  If your iPhoto library is being synchronized by using DropBox is your problem - you can not ever do this - that the iPhoto application can be used to change the iPhoto library - if you put on DropBox and sync, it you destroy

• How can I return to the 'parent' source after following a link in the page source?

  After following a link in the page source, I would like to be able to return to the source 'parent '. The only option I found is the source is completely closed and open the source of the page once more. A 'return' option would be useful here...

  I just tried to look at the source of the page and the previous/next buttons on my mouse worked.

  If this isn't an option for you, another option is to view the Page Source to use an external application of your choice who has previous/next buttons the value. Dafizilla ViewSourceWith can be used to define an external application to view the source. You can also define an external application by changing hidden preferences 2, the following 2 links show what to change:
