• SRS problem lock at the labview program amplifier with regard

  Madam, Sir, I have a labview program for SRS 830 lock in amplifier and problem is that the output is depends on the sensitivity... as we change sensitivity 500mv to 1v then exit hydro-huileuses changes. automatic gain function does not work. I'm so amazing that, about what the sensitivity, the output is correct. Please, help me to overcome this problem by starting the function of automatic gain. I enclose you than vi. When I run vi to autogain, then it displays an error and stop.

  'This error' mean? Time-out error or a parameter? If it is a parameter error, definitely check the manual to see if this is supported.

• NI 9148 with LabView module detection

  Hello

  I got the task of creating a deployable (compiled) software to a DAQ system with NI 9148 Ethernet RIO basket background and various modules. The user must have the ability to change the module type and the location of the different tests, so the application must detect (or the user specify) what modules are at what positions.

  I watched the blockset CRY, however this chassis is not supported and the lowest level blocks are protected. Is it possible to read the serial number of the modules connected to the 9148 OR position, type, and if all goes well?

  Thanks for any help!

• ACS550 control with LabVIEW

  Hello

  I recently implemented an ABB ACS550 player to control an air blower speed.  I was control the player through the interface on the disc itself.  However, I am now looking to control the device with LabVIEW.  I don't know where to start and I was wondering if someone could explain what I would need the equipment and the basic principles on how this control can be implemented.

  Thank you!

• Can I change the default settings for the latency time Serial Windows with LabVIEW

  I have a wireless data collection device that my business is that I am using for the test one of our other wireless products. The device sends data series to a PC via a USB port. I wrote an automated LabVIEW program to test all the functions of my new product. However, after firing in the data, I realized that the serial data coming very fast and requires me to change latency of Windows by default for the port COM 16ms 2ms Miss not nothing. It's pretty easy for me to do locally on my machine, but much more difficult for me to spec for an off-site CM.

  Is it possible to have my LabVIEW program change the latency time of the COM Windows port of 16 ms to 2 ms automatically?

  Are you talking about the FTDI driver? I know that they allow these changes through registry settings. Thus the approach would probably be to have a small registry script that updates the parameter of function. Most likely, this will have to be run with elevated privileges, as these parameters resident generally in the HKLM or HKCR rather than the HKCU one hive.

• upgrade to labview 2013 problems now with labview 8.6

  Upgrade to Labview 2013 a few days ago and framework installation changed my MAX existing since version 5.1 to version 5.5 with CAN 2.7.5.

  Because all my previous software was written in version 8.6 and customer requirements, this can not be changed and if I need 'backward compatibility '.

  However check the supported versions in CAN it only seems to go back as far as Labview version 10.0?

  Worse still, when I try and load any program written in LabVIEW 8.6 8.6 I now get "cannot find file" for the DAQMX as

  DAQMX------Write.llb------DAQMX------Write.vi etc.

  Tried the navigation in the folder named "MAX."

  The questions are:

  What I have to remove and MAX and re - install the earler versions for compatibility with 8.6?

  If so this can be done without removing my 8.6 install/2013 installs?

  Yes, the new DAQmx versions are not compatible with LabVIEW 8.X.  You can just uninstall DAQmx and then install your previous version to restore your support 8.6, but you will have lost the support of DAQmx for 2013.

• LabVIEW program works on a single computer, but does not work on another.

  We have a laptop running a custom data acquisition program that has been done with labview by an external company. It communicates via ethernet with a box full of material national instruments that is connected to some sensors. While it works fine on the laptop, try to install the software on other computers results in the following error message "year error occurred while trying to open the configuration file"C:\program files\ (program name) \data\ (name of our company) fieldpoint.iak. This error occurs whenever we try to open the settings page of test or run a test. I checked that directory and the file is actually there.

  New computers (we tried several) always have difficulty connecting to hardware via ethernet, and if you look at the network activity in windows, you can see a whole bunch of packages sent but only a little if any course of reception. I wonder if there is a network configuration problem? I tried with the settings as much as I can find, but nothing helped.

  The company that made the software does not meet the emails.

  Any ideas would be greatly appreciated!

  A thinking hand: the file you are trying to read is a FieldPoint config file. I don't know if the FieldPoint configuration file format changed with different versions of FieldPoint. You may not have the same version of FieldPoint installed?

• LabView program for lock-in-amp

  Hello

  I have to read the voltage level of a Lock-In-Amp and on the other to read the magnetic field of a Gaussmeter, simultaneously. After that, I should I establish a curve of respect of tension on the ground. Please give me some tips to write a good program with LabView to the stated purpose.

  Records,

  The program to read from the hardware depends entirely on the hardware you have.  Should what commands you send?  In what format the data is returned? (Your next step is to 1) check with the manufacturer to see if the LabVIEW drivers available or 2) to determine how to communicate correctly with the hardware.

  After that you are able to read a value from each of the devices, the next step is to place them in a loop and the wire to a chart.  (loops are graphics are basic and there are a lot of examples).

  Now another question; you said you're tracing the curve tension against the magnetic field, then how we control the field?  Do you also need to add the control of the magnetic field?

• Can I still change a LabVIEW program even if device drivers are not installed on the computer used for editing?

  Hello

  If I do not install device with LabVIEW drivers can I still change any given LabVIEW program created with this version?  Or do I need to install device drivers if I'm editing a program that uses these drivers?

  Thank you

  What you reinstall? The dll is part of the traditional DAQ driver.

• RS-232 via TCP/IP with LabView

  Hello

  I have currently a standard equipment is read through a RS232 converter TCP/IP hardware.

  On the computer with labview, I use a third-party serial port virtual that data reads the TCP/IP and converts this COM port data pack

  I then read the port COM normally with VISA.

  I would like to remove the third-party TCP/IP software RS232 and LabView read the TCP/IP port and convert to series.

  How could do?

  More details about the hardware and the 3rd party software;

  thydzik.com/Monitor-cms2000-Inverter-via-tcpip-usr-tcp232-E4-rs232ip-Convertor/

  More information on labview here code;

  thydzik.com/log-Solar-generated-to-pvoutput-with-LabVIEW/

  I don't think it's as complicated as you seem to expect. Try the VISA TCP approach. Create a resource of VISA TCP, in raw mode, as explained in the white paper. Take your existing code, replace the COM resource with the new TCP one, remove the configuration of the port series, and it might work. Make sure to close the resource when you stop the program.

  If you want to go with the TCP functions, look at the examples. You open a connection, read and write strings in it, exactly as you would with a serial port and close it when you are finished.

• Trouble with USB-6501 with Labview 8.6 Pro for Mac OS

  Hello

  I have a unit USB-6501 I try to use with Labview 8.6 for Mac Pro to processor intel.

  I have the driver NOR-DAQmx base 3.2 for Mac installed and when I ran "Isdaq", it detects the device and also warned that the firmware needs to be updated. So, I ran the "FWUpdate" for updating the firmware. I double check the Isdaq and it detects the device as "NI USB-6501:"Dev1"(USB0::0x3923:0x718A:014386 B 0: RAW).

  Now, when I run Labview 8.6 and DAQmx Base create channel VI and the port of 'physical' wire to the control, nothing appears in the available device.

  Also, when I run the mxbaseconfig program, not the existing basic tasks detect the device.

  Could someone please help me get this to work? Basically, I need to read and write slow digital data through USB-6501. But, the Labview does not detect the device.

  Thank you

  Keong,

  I do not know what causes this, but place a task create VI before your code and the wire of the output task to the task of entering the chain and try to run that.  Please let me know if it works for you.

• Can what cards I use to develop communication SPI with Labview?

  First of all, I'm an intern is currently working on a project that involves communication with an SPI interface. I have absolutely no experience with SPI, but I finally decided to try. I work for about 6 months with labview and understand the function of basis of a large number of its resources.

  The problem:

  We want to connect Labview to an evaluation Committee that is connected to the PC via USB (but it can also be adapted to connect through SPI). The evaluation board mainly reads and writes if sign up for issuers that are connected to it by a Module assessment. The program which is already which is the Studio of SmartRF (that works via USB), but as we want to link all the functions in Labview we redevelop a platform to do so. If shortly, we want to make a Studio of SmartRF version in Labview. We want to be able to get all the information that makes the program and others... and all this is possible through SPI.

  Here is a link in case you are interested what is SmartRF Studio: SmartRF Studio link

  My question is which card do you recommend for what we are trying to accomplish? We are looking for something not very expensive but who fail to meet our requirements.

  I think of the NI USB 8451, but please make suggestions.

  Thanks a lot in advance and please stay tuned to my many questions coming about how to accomplish this enormous task with no knowledge whatsoever of SPI or how to mix with Labview only one student. I am reading as much as I can find, so all the links will also be very much appreciated. If anyone has any experience with NI USB 8451 with Labview be kind enough to guide me

  Sincerely,

  Gisela

  If you have very little experience with LabVIEW and SPI, the 8451 is a good choice. It's expensive, but it's really easy to use and configure.

  The Aardvark is also a good choice. There pilots LabVIEW is also easy to use in LabVIEW. The disadvantages is that it doesn't have a lot outside of simply making SPI or I2C - in other words, it doesn't have a lot of GPIO. This can be important when control of multiple SPI devices, because it requires to select them lines individual slave.

  Dinah is really more than a product of laboratory, or something that is meant to be placed inside a camera. It is expensive, compared to the other two, but it doesn't have native drivers in LabVIEW. On the contrary, it comes with a DLL you can call from LabVIEW. I wrote a set of LabVIEW drivers for it, but I can't distribute.

  There are other products on the market, which some will resemble a device series to your computer. For example, you would use VISA to communicate with the SPI controller, and it would appropriate communication of SPI.

  Among the three mentioned here, I would suggest that you go with the neither of the Aardvark, one.
