IMAQdx: Invalid camera session

I want to use GigE camera on LabVIEW2011.
I have already installed Vision Acquisition software (ver Aug 2012) and got image on NI MAX.
But on LabVIEW2011, I could not get image. Error was occured as follows.
Error code 1074360315 was occured
on IMAQdx Get Image.vi
NI-IMAQdx: (HEX 0xBFF69004) Invalid camera session
Please help me.

Is there a way to determine if a IMAQdx camera session is still valid or not ?

If it's valid, IMAQdx Open Camera.vi will return an error.
If it's not valid, IMAQdx Close Camera.vi will return an error. And IMAQdx Close Camera.vi is very slow when the camera session is not valid.

I mean IMAQdx Open Camera.vi haven't been called yet, or IMAQdx Close Camera.vi has been called.
Although there is no property node for that purpose, other properties, such as camera vendor name, are acceptable workarounds.

IMAQdx Open camera.vi Vs IMAQdx snap.vi enquiry

Hi,
I have an application for image aquisition and processing. initially it was set to IMAQdx snap.vi followed by IMAQdx Open camera.vi in a loop, since the application required minimum time consuming for image capturing and processing, so I put IMAQdx open camera.vi in outside of the loop, leave IMAQdx snap.vi only in the loop, it means whenever program run, open camera runs one time only, IMAQdx open camera.vi session out wired to IMAQdx snap.vi in the loop, but it was found error pop up when program runs to IMAQdx snap.vi, it shows err occured at IMAQdx Open Camera.vi. reason is camera already in use.
Question: 1. I have IMAQ open camera in outside of loop and transfer the session out to IMAQdx snap.vi, IMAQdx
                   snap.vi should run directly, why it still execute IMAQdx open camera.vi again?
               2. right now I don't have IMAQdx close camera.vi in the program and I will add in later, when program
                   runs to the step of IMAQ open camera.vi, error out shows Ok and no error. so the problem is not due to
                   program without IMAQdx close camera, right?
Pls advice. attached is the error msg. thanks

shows camera in use when IMAQdx snap run.JPG ‏98 KB

If you look at "IMAQdx Snap.vi"'s diagram, you'll see it works the following way :
- if you do not provide a Session in, it will call IMAQdx Open on cam0 and then, after acquiring an image, will call IMAQdx Close
- if you provide a Session In, it will just acquire an image, the camera session will not be closed.
As you are in the second case, your session id is still valid and you should not call IMAQ Camera Open in the loop.
Anyway, calling IMAQ Snap is not the most efficient solution. You should consider using either IMAQ Grab or low level VIs instead.

Error - 1074360266 occurred at IMAQdx Open Camera.vi

Hello,
We're having issues with our LabView vision system; the VI is able to "run" with an unbroken arrow, but there is an error that appears:
"Error - 1074360266 occurred at IMAQdx Open Camera.vi" with a possible reason of "NI-IMAQdx: (Hex 0xBFF69036) Unable to attach to the kernel mode driver"
For a little background, we had originally programmed the VI in LV2009 (where it worked fine), but the customer upgraded to LV2010 (where it now comes up with this error), so it would be logical that this has something to do with the problem. Also, we're using two Basler A601f cameras via Firewire connections, which are both recognized by Basler's Pylon Viewer software, so we're fairly certain this is a LabView-only problem.
We've tried reinstalling the Vision Acquisition Software drivers, but that didn't fix the issue, so we're kind of at a loss.
Any help or pointers are appreciated, and I apologize ahead of time if I left out any pertinent information. Thanks.
Ben
Solved!
Go to Solution.

Hello
Sorry if this isn't the right place to post this question, but I'm new here.
I have a similar problem, I'm trying to operate a Basler A601f camera with Labview trough a IEEE 1394 connection.
At first I could see the camera in MAX, and manually grab images, but when I tried to create a labview project, it wouldn't recognize my camera. Also, the remote systems tree in MAX wouldn't show anything.
I tried to do a full re-instal of all NI software, but things got worst. Now MAX can't detect the Basler camera either.
Also, when I select Devices and Interfaces in MAX, a "Unexpected Internal Warning" appears.
Anyone can give me some advice on how to solve this? If you need more specific details just ask.
Thanks in advance!

How can we cleanup invalidated archive sessions (remove from UNIX)

Over the years, we have accumulated many invalidated archive session files in our archive directory in UNIX. We would love to remove these invalidated session files to free up space.
We have been looking at BC_ARCHIVE ... but the documentation on it only mentions the archive of logs ... not the cleanup of invalid session files that need to be deleted
Can we just delete the files of sessions that are invalid? Or must we perform some function in SAP to delete them? SAP ... can you document the process for this?

Hi,
You can simply delete the archive files at unix level thats all. No need to do anything else in SAP.
Cheers!

ECC-- SAP PI-- Successfactor Integration: Invalid SFAPI session

Hello Experts,
   I am working on EmployeeData Synchronization interface the content of which is predelivered from SAP.
I configured the interface and while testing
as first step I was able to retrieve the session ID from Successfactor,
but using the session ID retrieved from Successfactor cloud application when I am trying to upsert data in the second step I am getting an error "Invalid SFAPI session".
How can I overcome this error?
I have done my research on the SDN and went through the blogs but for not much use.
I am sure about the content and the version being used by me as the correct one.
Has anybody seen this error and if yes how did you overcome the same?
Please let me know.
One point that I have to make is that since I was able to retrieve the session ID I did not install the certificates from Successfactors.
Is installing the certificates mandatory and if yes which step is this being referred?
Any help is really appreciated.
Anu Patyath

First of all, you should get it running with SOAP UI:
Please make sure, you got those steps right behind each other:
login
upsert
logout
The important step is to set "Main HTTP session":
You can use the payloads for login, upsert and logout as they are generated by SOAP UI when importing the WSDL.
e.g. upsert:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:urn="urn:sfobject.sfapi.successfactors.com">
   <soap:Header/>
   <soap:Body>

USB camera problem - Error -2147024882 occurred at IMAQdx Open Camera.vi

Hi,
I have just started to try and use a new USB camera (5MP) on LabVIEW and I am getting this error (Error -2147024882 occurred at IMAQdx Open Camera.vi) along with the message
LabVIEW: (Hex 0x8007000E) Ran out of memory.
=========================
NI System Configuration: (Hex 0x8007000E) Out of memory.
Also MAX comes up with the error "0x8007000E Buffer size used is too small for minimum aquisition frame"
Is there a maximum camera resolution that MAX/LabVIEW can handle? Can I increase this buffer size?
I am using LabVIEW 2012 and MAX 5.5 on Windows 7 and the original MS LifeCam is working fine.
Thanks in advance
Ivan

Hi IvanChurch,
-I've used your code and it's working fine in my pc.I was able to capture image using webcam. Seems no problem in this, still added delay in while to ensure proper delay is given for pc.
-Little bit of curious about your system config,particularly RAM size and free available during labview execution (can find this in Task Manager). Because if labview didn't have any free space during execution, it might be throwing this error.
-If the available free space is too low during execution, may be try clsong all other applications and try acquiring again.
Please revert back if the problem is not fixed
Thanks

Invalid Kiosk session configuration...

Guys,
I have a Solaris-based SRSS 4.2 installation. I have Global Kiosk set to connect to VMware View server (and it works fine).
I have certain people that need to connect to their Linux desktops. So I created another Kiosk configuration using the Kiosk Mode Generic Session (http://wiki.sun-rays.org/index.php/SRSS_Addon:_Kiosk_Mode_Generic_Session)
My generic.conf looks like this:
KIOSK_SESSION_EXEC=$KIOSK_SESSION_DIR/generic-session
KIOSK_SESSION_LABEL="SGD"
KIOSK_SESSION_DESCRIPTION="Provides an SGD X session for running a Kiosk script."
KIOSK_SESSION_ARGS="/usr/bin/firefox http://sgdserver/sgd"
KIOSK_SESSION_PROTOTYPE=generic-session
I have then ran these commands to import the configuration and assign it to certain users:
# utkiosk -i SGD -f generic.conf
# utkiosk l
SGD
session
Now assign the SGD configuration to users token:
# utkioskoverride -r Payflex.xxxxxxx -s kiosk -c SGD
Heres the kick If I set Global Kiosk to SGD, it works fine and brings up SGD login page as it is supposed to.
If I set Global Kiosk back to View and try to use a smartcard to bring up SGD for the particular user, I get:
Login Incorrect, please try again
then an error stating:
Error starting Kiosk session: Invalid Kiosk session configuration
In the logs I see this:
kiosk:initsession[14382]: [ID 702911 user.error] Error: $KIOSK_SESSION not specified
Jan 12 15:30:55 dsys-vfrb-sray1 kiosk:initsession[14383]: [ID 702911 user.error] Error: failed to load Session Descriptor
Jan 12 15:30:55 dsys-vfrb-sray1 dtlogin[14250]: [ID 705508 user.error] pam_kiosk: pam_sm_open_session: Child process /opt/SUNWkio/lib/initsession failed with exit code 1.
Any ideas? It works fine in my Lab, but at a customer site, it does not work!
Thank you in advance for your help!

I have then ran these commands to import the configuration and assign it to certain users:
# utkiosk -i SGD -f generic.confUnfortunately Kiosk has two kinds of *.conf files: session descriptors (see the kiosk(5) man page) and session configurations (see the session.conf(4) man page). And these types are rather similar - some settings can be in the descriptor as default, but also in the session configuration. The generic.conf you have is a session descriptor. Those must be stored into /etc/opt/SUNWkio/sessions/. But for import into utkiosk you need a session configuration. Probably utkiosk should do more validation of the configuration you are importing to protect against this confusion.
The generic session is intended for configuring any command to be executed from the admin UI. If you know your command and need a prototype, you should go the extra step and make a specific session. Here is how:
Rename your file to /etc/opt/SUNWkio/sessions/SGD.conf and change it to be:
KIOSK_SESSION_EXEC=/usr/bin/firefox
KIOSK_SESSION_LABEL=SGD
KIOSK_SESSION_DESCRIPTION=Provides an SGD X session for running a Kiosk script.
KIOSK_SESSION_PROTOTYPE=SGDAlso rename your /etc/opt/SUNWkio/prototypes/generic-session directory to /etc/opt/SUNWkio/prototypes/SGD, as per the last line above.
You can leave the KIOSK_SESSIONS_ARGS line in the file, if you wish, but it will just be a default, so I'll show how to set the arguments via utkiosk.
To verify that you have set up the descriptor correctly, use
/opt/SUNWkio/bin/kioskdesc print SGD Now create your session configuration:
# utkiosk -i SGD <<!
KIOSK_SESSION=SGD
KIOSK_SESSION_ARGS=http://sgdserver/sgd
! Of course you can also put these two lines into a file and use it with the -f argument to utkiosk.

Invalid camera view index

Hello,
i keep getting an error box popping up
After Effects error: invalid camera view index.
(26::327)
the error pops up continuously so I have to force quit.
there are no cameras in the comp.
using afx cs5

thanks

This just happened in four comps turned in by students of mine. All four students, along with the rest of the class, used the same assets, did basically the same work and used cameras. I think this relates to the "Views" and the Active Camera. All four were in 2 Views Horizontal with the Active Camera in one of the views. The Active Camera view was not displaying properly. I clicked on the Active Camera panel to select it and the error messages went away.

Error -2147418113 when Open Camera Session

Hi
I am using an USB Camera for my setup. I always get an error message (-2147418113) when I start-up my PXI system and open the camera session. I see the camera in MAX and its also possible to read out the camera information. But it fails when I try to open the camera session or when I try to grab an image in MAX.
After re-connecting the USB Camera I dont see the error mesage anymore and everything works as expected! Is there a workaround the reinitialize the USB Port or..?
Thanks in advance

Invalid vi session

Hi,
I am using PX-1042 system with the power supply NI PXI-4110. I initialize the supply in the start of the program which works fine, but as soon as the cotrol goes into the block where it reads the Voltage and Current continuesly, an error window occurs which says.
"Error -1074130544 occurred at niDCPower Measure Multiple.v"
"Possible reason(s):Invalid VI session."
In this block, I don't initialize the Power Supply again as I have done it already. I have also attached the whole code here. Any one please give me the solution to get rid of this error code.

You are not using the instrument handle that was created when you initialized the instrument. Instead you are using the VISA resource name. That is not the same as the handle. You should be using the purple wire called handle coming from your initialization VI, not the VISA resource constant.
There are also a few odd things going on. Don't use a value property node for measurement when you have the terminal available. Also, your false constants wired to the while loops means the only way you can stop the VI is by aborting it. You could also merge your two different event structures into one.

Possible reasons for error 1074396005 invalid avi session

Dear All,
I am working on creating and writing frames on to AVI files. I need to start writing frames up on record on command and close the AVI file up on record stop command. I am trying to read frames from an recorded video and write in to another AVI file.
But i am observing Error 1074396005 invalid avi session, whenever i run the code. I am using AVI2 VI's (IMAQ AVI2 Create, AVI2 Write and AVI2 close).
I am using LabVIEW 2013 SP1 and Vision development module versions.
Below is the block diagram for reading an avi file and writing in to avi file upon record on command (numeric control value 1 to case selector)

Below is the error observed:
Kindly suggest what would be the possible reason for the error.

Might be good if you can post the code instead of screenshots.
-If session was closed or aborted due to some reason you should get this error.
-Multiple times you are creating the session inside the loop with same avi session, is it required?
-Are the images added to the avi file?
