Error 10609

Got "Error 10609 occurred at AI clock config"

 

possible reasons:

NI-DAQ LV: A transfer is already in progress for the specified resource, or the operation is not allowed because the device is in the process of performing transfers, possibly with different resource.

 

I am trying to run an old labview code which connects to a laser system. I was trying to correct an error (-1073807339) by playing around with the time out value and then I suddenly started getting the 10609 error as well. The code was running until yesterday. I don't understand what could have caused this error msg. I also tried restarting the computer a few times. Can someone please help me out? I am using Labview 8.5 with a PCI-MIO-16E-4 device.

Hello,
I am using Keithley 2400-C Sourcemeter, Labview 2013(32 bit), Keithley Drivers Version 3.12 and my Laptop is 64 bits and it has Windows 10. The  Keithley Source meter is connected to the laptop via the KUSB-488B. I am running a program on LabView (it is attached, more specifically I am running the 2400swV 4wires v2.vi) and when I press the button Start Linear Stair Sweep the Keithley makes a beep and shows an error 800: illegal with storage active. I am also attaching what the NI MAX and the VISA Test Panel shows. I used to do all these with another PC and there was no problem. What is the problem now?
Thank you very much

Recommendations for GPIB to Fiber extenders

I need to be able to isolate my GPIB cabling into an anechoic chamber using a pair of GPIB to Fiber extenders. I have a pair of HP 37204 extenders but when I connect them up to my NI PCIe GPIB card, Automation explorer reports "Too many listeners" and won't even try to poll the port. When I connect the same extenders up to a Keysight PCIe card, it reports 240 GPIB devices found and makes the interface "Connection Expert" basically unusable. Can anybody recommend a brand/model of GPIB/Fiber extenders that behave with NI GPIB?

Siglent SDG2082X

Dear all,

 

I have got a Siglent SDG2082X waveform generator that I would like to control from a C program using the Siglent IVI-C driver. The generator is connected to the LAN interface and is correctly detected and identified by the Keysight Connection Expert (that uses VISA functions as far as I know). The sdg_init() function (or IviFgen_init() when called by the class driver) returns -1073807300 (bfff003c). This corresponds to the VI_ERROR_ALLOC error and means "Insufficient system resources to open a session or to allocate the buffer(s) or memory block of the specified size.". The documentation only explains how to install the driver but does not say anything about options that should be specified when calling the sdg_InitWithOptions() function, e.g. a memory block size. I use this driver: SDGX IVI Driver - 1.0.1R0 (Release Date 04.04.18 ) (https://siglentna.com/download/5119/) It seems to be the latest available version.

 

I have set up the generator in NI MAX the same way as I have done it for my SSA3021X spectrum analyzer which returns VI_SUCCESS when I call the init function.

 

Is there anybody who can give me a hint what I am doing wrong here or is there a way to find out which options the sdg_InitWithOptions() function accepts? I have already tried to contact Siglent Europe to get information about the driver but I did not get an answer.

 

Any help would be appreciated.

 

Thank you very much and kind regards,

keithley 2400 connection issue even output off

October 18, 2019, 2:50 am

keithley 2400 source meter is used to charge a capacitor in the lab controlled by a labview programme. But as soon as the charging process is finished (programme ending at the same time) and the front panel of keithley shows "output off", the capacitor starts to discharge automatically, indicated by other in-operando measurement (a spectrometer). this means the capacitor is short connected via keithley 2400 source meter although output is turned off controlled by the programme. In my opinion, the source meter works as a short circuit before disconnecting the capacitor from it. Am I right?

if so, is it possible to disconnect the capacitor through programming (adding functions at the end of programme) instead of directly remove it to avoid automatically discharging?

GPIB-ENET/100 IP address configuration

Hi,

I am looking for a NI-488.2 driver for either opensuse 42.3 or MacOS 12 to reconfigure the static ethernet address of a NI GPIB-ENET/100. I set it to factory default, but was not able to communicate with the device using the gpibexplorer in NI-488.2 Version 18.5.0 for macOS or NI-488.2 Version 19.1 for opensuse 42.3. It seems that these NI-488.2 versions are only supporting the NI GPIB-ENET/1000 devices. I connected the device directly to the respective computers (on the opensuse machine on eth1). The search in the gpibexplorer did not reveal any devices.

Can PCI-8430/2 RS232 Card Reach +-12V Output Level?

Hi,

 I need to interface some old equipment that requires +-12V on its serial port. Would PCI-8430/2 do the job? How can one set the output voltage levels for this card? Can it be used just as another COM port, i.e. not NI specific?

 

Thanks!

I want to know if the software drivers ( NI-845x 18.0 ) is 32-bit or 64-bit and if it is 32-bit that means some features won't be found.

The idle level of output in 2-wire auto mode is 0v, shouldn't it be logical high +5V? Check some data that  there is no bias resistance, but the bias resistance  how to add,  no one can explain in detail. How to solve this problem, hope answer!

Connecting to Old Instruments Having +-12V RS232 Voltage Levels

Hi,

  I have an old piece of instrument built in the 1980s. It requires +-12V voltage levels for the RS232 interface. My eBay USB to serial dongle doesn't work. Can someone suggest a PCI or PCIe card that can reach +-12V? For example, can NI's PCI-8430/2 do the job? I found the following table in the file http://www.ni.com/pdf/manuals/373170f.pdf, where the "Driver output" is listed to be 5 to 25V. Is this the voltage level of the signal, such as the "Data Treminal Ready" (DTR)?

I am having problems getting MAX to recognize instruments.

It only sees two power supplies

However, The VISA interactive control Sees all of the instruments.

I have downloaded the latest version of DAQmx, Visa and 488.2, but it still has the problem.

I don't know if this has anything to do with it, but some of the articles I read said to use the 488.2 utility in the tools menu. This is not showing up in the menu.

Another article suggested checking the properties of the USB-GPIB-HS properties. That option also is not available.

How to control two devices with GPIB-UBS-HS+ in VB 2019 ?

Hai, I am working with Visual Basics 2019 to control two devices using GPIB-USB-HS+. I could control one device by following syntax.

 

Imports NationalInstruments.VisaNS

 

Dim GPIB_ResourceString1 As String

 

GPIB_ResourceString1 = "GPIB0::8::INSTR"

mbSession = CType(ResourceManager.GetLocalManager().Open(GPIB_ResourceString),

MessageBasedSession)

 

mbSession.Write("OUTX 0 ;")

 

response = mbSession.Query("OUTX ?").

 

Then how to control two devices with GPIBs? I could connect the two devices using two GPIBs, but not able to send command and read the response from a specific device. Can anyone help me in this? Thank you in advance.

PCIe-GBIB card vs. GPIB-USB-HS

Hi All,

On my PC (Win 10 OS 64-bit) unit I have labview software in executable version. In measurement procces three external devices with GPIB communication ports and one through serial port COM1. Firstly I installed PCIe-GPIB card. Using NI Max I checked communication with all external devices and it is ok. Then I started measurements on above labview software, and at beginning everything looks alright. However after few minutes operating system is rebooting and also software breaks down. 

 

Change from PCIe-GPIB card to GPIB-USB-HS converter solve this problem. Everything works normally without any issue. However I am curious why it is workig well through usb port rather than card. 

 

Did anybody have sucha situations? Did you have any explanation or suggestions what could checked to operate on PCIe-GPIB card?

 

Thanks in advance for any suggestions and help,

Borsuk

Controlling Mettler Toledo scale (ML3002T), there are no Labview Drivers for this scale

I need to be able to tare(zero) a scale with labview. The scale I'm using is the Mettler Toledo ML3002T. There are no drivers for this scale in labview. I also need to get the current weight displayed by the scale. Mettler Toledo scales use MT-SICS to send commands to the scales. Is it possible to be able to send those commands with labview to the scale?
