Hello,
 
I downloaded the Agilent 8114a driver from the NI Website for programming it in LABVIEW.
 
I found there is this "Configure Voltage vi" in which there is the option of Voltage Baseline as shown below.

I really need to use this Baseline option to set my voltage base. But I dont understand where to find and install this "Option 001" to use this Voltage Baseline option. 
 
It would be great if you guys can give a quick response. I have an urgent deadline. 
 
Thank You for your time.
 
 
Regards

GPIB to Ethernet

We have an old test system used to automate the testing of certain devices. Some instruments in the system are old and need replacing. But the units are neither serviceable nor replaceable, So we need to find new hardware.

But again We cannot edit the code of the control software to add in the commands for the new hardware.
So, I want to make a little black box which will sit between the controller and the new instrument and translate the old GPIB commands and transmit via ethernet.

So my black box will need to act as both an instrument and a controller in order to pose as the old instrument but then control the new instrument, but also work in reverse to send the reading back to the controller.

If i make system like that how old system will identify my system as test instrument. What settings i should do for that

I want to set up two computers to communicate with each other via GPIB. I have made one as a system controller and other one as listener. But when i try to scan the instruments in NI MAX, it is not showing my listener PC address. But it shown all other test instruments which is connected via GPIB.

Why it is not detecting for listener PC as it will detect for other test instruments.

Instrument Getting Hung on multiple queries from PC using HISLIP .net

Need help understand the issue.

 

We are facing strange problem of instrument getting hung up after few days of operation.

 

I have implemented NI VISA using HISLIP to an instrument where one thread is continuously querying the status and parameters of the instrument in C#.

 

Another thread is running which sets one or two parameters every few minutes and exits.

 

I have implemented all threads to open session and keep it alive i.e. session opened is not closed and kept open. (I tried opening and closing session also but the same issue persist)

 

I understand multiple client can connect to instrument using HISLIP but I think this may be a problem.

 

Can anyone please help. Let me know if you need anything from my side.

 I am using a sensor evaluation board for which LabVIEW supported VIs (exe file) are provided by the board vendor.  While running the VIs it is giving the following error. 

"error connecting to GPIB device/driver.driver NI 488.2 may not be installed".  

 

I have installed the NI 488.2 driver separately(NI  4882_1850f1) for correcting the error but still facing the same issue. Please suggest the possible reason and the resolution for the same at the earliest. I have attached the error screenshot for your reference and help.

Hi,

 

I have a new project coming up and would like to know if the old Agilent 34401 driver will work with the newer Keysight 34460 meter. I would like to get away without making any changes to my existing Dll that I made with the older driver. Has any one used the 34401 driver with the new 34460?

 

Thanks,

Communication Issue with Varian V-70 Turbo Pump Controller

Hey All,

 

As a prelude, this issue may likely not be VISA related so much as related to either my physical connections or my misunderstanding of the product datasheet. Any help would be appreciated, but I can also reach out to the manufacturer if needed.

 

I am trying to command a Varian V-70 Turbo Pump controller from my host Windows 10 PC via a USB to RS232 adapter cable. My software configuration is as follows:

  • NI VISA 19.0
  • LabVIEW 2017 SP1 f3

I have tried to communicate with this device in both LabVIEW and in a VISA test panel in NI MAX. In both cases, I get the classic timeout error:

Capture.PNG

 

Attached is the manual for the device. Pages 74 and 75 are of interest, as they outline the physical connections and communication setup in software. Below are two relevant snippets:

 

connections.PNGCommunication Port

 

messageformat.PNGCommand and Response

I have ensured my VISA session is configured with the correct format (baud rate, data and stop bits, parity) and have also tired timeouts of various lengths. In addition, I have followed the manuals instructions for ensuring the controller is in the proper mode to accept commands via RS232. Based on everything I have tried, the questions/thoughts I have are as follows:

 

Questions:

  1. Does the first image imply in any way that a USB to RS232 converter could cause issues? The phrase "The external cable (not supplied) between the host computer and the controller doesn’t require any crossed wires so that the signal are connected correctly." is confusing to me.
  2. If (1) is the case, maybe I actually need to be using NI Serial 19.0 with a RS232 cable instead of a USB to RS232 adapter?
  3. To me, image 2 implies the commands are literally just the characters "A, B, C..etc" I am not familiar with the concept of a CRC, but some googling has explained the concepts yet I am unsure how this affects how I format my actual messages.
  4. To build off of (3), do I need to be formatting my commands as Request + CRC or is the CRC handled by the nature of VISA and the setup of my VISA session?
  5. I am not familiar with USB RAW mode, but maybe I should be using that?

Articles used:

Error -1073807339 VISA Read or Write Timeout

How Can I Communicate With a Device Using NI-VISA USB RAW Mode?

 

Thanks for any help!

Hi all,

 

I am reading power values through a USB configured power sensor in Labview.

I tried the manufacture software (EXE stand alone), and it is working; which may indicate my connection is correct.

 

1) Please see my labview codes as attached file "codes.PNG".

2) However my labview codes has following error: error -1073807339 VISA Read.

3) The screen shot of device manual was also attached here "manual"

 

May I ask if someone can give me some tips to solve this issue?

Trying to connect Keithley 6517 A to Lab View Driver for the device using GPIB to usb Connectiong

I am trying to read data from Keithley 6517A. I am using Agilent 82357B GPIB-USB Interface High-Speed connection in order to read the data from the device to Labview. There seems to be a missing bridge of connection between the Keithley and the program. I already installed the driver for the Agilent 82357B GPIB-USB Interface that came with it and I am using the Vi for Keithley 6517A downloaded from NI. When I select the Visa Resource name the electrometer does not seem to pop up and the error message is given as followed...  
 

Data.vi<ERR>
<b>Reference Not Found:</b> (xBFFC0012) Cannot retrieve user data for the given resource name as there was not data associated with the resource name. Before you can read data, you need to write the user data using the Write Data action of this User Data VI.

 

Any suggestions or solution

My question is : Can I use this driver for the DSA875 ? I use the Spectrum analyser DSA875 (7.5GHz)

According to RIGOL DSA800 Series Instrument Driver Readme:

Supported Language(s): LabVIEW
Supported Model(s): DSA815, DSA815-TG  
Model(s) Tested: DSA815

The DSA815 is limited with 1.5GHz. They don't talk about the other model, just only the serie DSA800. How I can be sure that it will work with DSA875? I need to know

Does anyone know ?

Thanks, Julien

Hi, I'm new to the Modbus protocol and I want to implement a new system using Modbus and a FL1F low cost smart relay.

Product specifications:

TCF modbus

The company only sells the program to use it

Anyone have experience or something with this product?

 

Do you recommend another type of relays to make a centralized system (low cost and using Labview)

Hello.

 

I am trying to use both NI 9751 and NI 9757 module with cRIO 9045 controller.

Both NI 9751 and NI 9757 require a power from a battery, so I bought 12V automotive batter to power both of them.

1. Now my question is what wire size should I use when connecting the battery to the modules?

2. Also, what wire size should I use for NI 9751 if I want to connect the injectors to the module?

The connection distance will be within 10 ft. Thank you!

Here's the program I use to save waveform to data, but the txt file I get is always grabled. I'm not sure if I need to convert the data form or use other function other than the one I'm using 'write to binary file'.

Code:

fetch (waveform to data).png

txt file:

data.png

By the way, the file can be normaly read back to waveform.

NI-488.2 GPIB-USB-HS+ driver for Windows XP Mode within Windows 7

Hi

I'm currently facing an issue about using GPIB-USB-HS+ on Windows XP mode in Windows7 machine.
And my NI488.2_v2.7.2 is not working, issue is about the driver can't be working correctly. However Windows XP is the only working version for this product.

I found some people were facing similar issue and the fix is in "https://forums.ni.com/t5/Instrument-Control-GPIB-Serial/NI-488-2-does-work-on-Windows-XP-Mode-within-Windows-7/m-p/1767076#M50236".
Somehow, the download like in the fix is no longer available and looks NI website now only provide three 488.2 driver which no one can be used for Windows XP. (I don't get why old driver should be removed from the website)

Can someone from NI please let me know how to get the fix in "https://forums.ni.com/t5/Instrument-Control-GPIB-Serial/NI-488-2-does-work-on-Windows-XP-Mode-within-Windows-7/m-p/1767076#M50236"?
It looks to me NI-488.2 v3.0 has the fix I need, it would be much appreciate if you can send me the installer file of NI-488.2 v3.0.

Regards,
Jarome
