64-bit Labview 2013 Ni-845x = ?????

$
0
0

Rediculous....

 

If I have the following setup:

 

- Windows 7 64-bit

- Labview 2013 64-bit

- NI USB-8452

 

What driver do I use??????? 

 

v2.1.2 is 32-bit only...

 

v2.1 coverd 64-bits but not for Labview 2013, stops at 2012. Found this in a random compatibility chart no where near the damn driver or HW pages. 

 

This is a maze of information, and digging for info like this should not be the norm.

 

My NI USB-8452 is glitchy when looking for it in NI Max. When I try to use the driver for I2C setup and immediately disconnects from USB (I hear the Window USB disconnect noise).

 

Has anyone had this problem? What driver do I use for Labview 2013 64-bit  for the NI USB-8452.


viFindRsrc returns nothing using VISA 14.0.1

I have software that uses the following method to identify PXI card addresses in a PXI chassis.

 

viOpenDefaultRM (&rm);

viFindRsrc (rm, "?*", &vi, &retCnt, desc);

viFindNext (vi, desc);

viOpen(rm, descs[i], 0, 0, &vi);
viGetAttribute(vi, VI_ATTR_MODEL_NAME, &model);
viGetAttribute(vi, VI_ATTR_MANF_NAME, &mfg);
viClose(vi);

 

This works on all PXI systems so far using NI VISA 5.4 or earlier.

So the problem is that now we have NI VISA 14.0.1 installed and this no longer works.

 

I can't find anything about NI discontinuing this functionality, so I am asking if anyone know why this would stop working?

HP 8596 Spectrum Analyzer Data Collection

Greetings,

 

 I am doing a project to read data from "HP 8596E (Agilent/KeySight 8596E)" through MIL-STD-461E, CE102 standard. The program should plot the spectrum as well as save it to a spreadsheet. As I understand from the requirement, the data should be tested from 10 KHz to 10 MHz (section 5.5). I sat my program to start from 10000Hz with an increment of 100 (for 400 times) because the maximum points that I can read from the analyzer through “TRA?;” is 401. So the total turn to be 50000Hz (10000 + (400x100)) then I repeat it again starting from the new frequency 50000Hz and do the same thing again and again till I reach 10MHz. Unfortunately this take really long time to do it this way, so I was wondering if there is another way that I can us the command “TRA?” for more than 401or if I should repeat “TRA?” and run in parallel the frequency increment?

 

Thanks

Capturing FFT waveform from Agilent Oscilloscope and displaying on LabVIEW front panel.

Using LabVIEW I was able to command the function generator to output a signal. I then commanded the oscilloscope to capture the waveform and plot the FFT. I now want to take the FFT waveform displayed on the oscilloscope and duplicated it to display on my front panel vi. How do I go about doing so without using any drivers?

I installed NI-488.2 into my PC, window 7 64 bit OS.

In the program >> project> add reference>.NET, I successfully add the NI.4882  into my visual basic  program.

By the way, this program worked well in another window 7 32 bit PC.

 

But when I run the program at ildev(BDINDEX,.........), error comes up as "unable load DLL gpib-32.dll".

So when I looked at c:\windows\system32, I can not fine gpib-32.dll.

 

Doesn't  NI-488.2 driver install gpib-32.dll?

 

How can I install gpib-32.dll?

HP E3631A loses connection with Labview after extended use

$

Hi all,

 

I have an HP E3631A connected to my computer using an RS232 to USB adapter and controlled with a Labview VI. When the VI is started it controls the power supply nicely, but after a while (ranges from use to use, approximately 40 minutes or so) labview loses connection and no longer controls the supply. When I try to stop the VI, labview freezes. When I try to close labview, a message of "Resetting VI: ... " shows on the screen. I have used the same adapter and power supply on another computer and didn't experience this issue. I have also adjusted the USB power options to disable the "selective suspend setting". Any other thoughts on what the problem might be? Thanks in advance.

Dear colleagues, The error message EE.er came up in the controller (Eurotherm 201) display and I cannot operate my Carbolite furnace. Up until then, I was using it at low temperatures (300C) for biomass-to-biochar conversion experiments. The message appeared suddenly without any misuse or malpractice. I am going through the operation and maintenance instructions Manual but I cannot even access the user calibration set up. Any ideas ? thanks Dimitris Kalderis Lecturer Technological Educational Institute of Crete Department of Environmental and Natural Resources Engineering Crete, Greece

MAX error insufficient location information or the device is not present

Hello,

    We have been getting this error once in a while on our test system.  (See attachment)  Our system is running Windows 7, MAX 5.5.0f0, TestStand 4.2.1 and LabView 2010 SP1. 

 

   To get the error to clear and the system to run we have to go in and rename each VISA to a bogus name and save it.  Then go back and rename them back to what they should be and save again. 

 

   We get this error maybe once every 3 or 4 months, but it does stop production until we get in and fix it.  What is going on and how do we fix it?

 

Thanks,

Steve Feeser

 

 

 

 

 

 

 

 

GPIB-RS232 Converter

Hi:

 

I have the following setup.

 

Advantest Programable Voltage/Current Generator's GPIB Port (it is a GPIB Instrument) is conntected to a NI GPIB-RS232 Converter and Convertter Serial Port is conncted to a PC Serial Port..

GPIB-RS232 is configured in S-Mode.

 

I created a Hyperterminal for communication with  Advantest.

The Hyperterminal seems working, I tested Loop Back test, when typing a character it appears  twice on PC monitor indicating the Hyperterminal is working.

I typed ?, or *ID? , but didn't get anything (expected ID information from Advantest).

 

Question:

 

How do you communicate with Advantest? 

For example, if you want to set Advantest for 10 mA current, what command do you use for this.  In otherwords, I don't know what to type  or command language to use in the Hperterminal screen.

 

 

Appreciate your comment and suggestions.

Hi,

 

I'm having issues interfacing a Keithley 2400 with a GPIB USB HS adaptor. My Windows 8.1 machine is not picking it up when the adaptor is connected to the Keithley 2400. In addition, none of the lights on the adaptor light up. I've attached some screenshots for further clarification.

Any assistance is appreciated. Thanks.

Dinamic Inputs requirements to SubVIs

$

Hi All,

I am not an expert on Labview, but recently I adapted some serial protocols created some years ago for an acquisition system.
I have two different boards to communicate with, both have their own protocol. I have two SubVIs just to communicate to witch one at a time. They are in everything similar, the only thing that changes are delays, timeouts and the serial message.

I manage to combine both in only one and I am feeding the input data in a cluster, though the list of commands just doubled.

 

Similar to most of the modulus available to work. Is there any cleaver way of somehow dynamically change the input types and combo boxes default depending on other input we link on the calling VI?

 

For instance, when we simply build an array if we connect to it a number the rest of the inputs expect a number too and automatically give an error if I try to connect a string to it!
In this case I would like that the board address for instance, automatically adapt other inputs to the expected commands of the that especific built in protocol.

PCI GPIB card not indentified

$

I'm using a PCI-GPIB card that has been working in an 7 year old Vista PC. To test for a newer software version I moved the card to a 64bit Windows 7 PC (after installing the 14.0 drivers) where it worked fine. But after moving it back to the Vista PC (and the same problem appears now on the Win7 one) the card is not automatically identified anymore. It shows up as a PCI Simple Communications Controller with the Hardware ID PCI\VEN_1093&DEV_C8A1. After manually assigning the PCI-GPIB driver it shows up with the correct name and the device manager reports "The device is working properly". But in MAX it only appears as PCI-GPIB "c0000091" without any of the GPIB context menus. And of course the software using the GPIB devices doesn't detect them. Is there a way to get the card running properly again? Thanks
