Hello,

I want to implement controller level redundancy in a cRIO based system.

I am considering cRIO 9144 as base chassis, connected to 2 cRIO controllers over ethernet/ethercat. So that if one controller fails, other one could take over. I have seen daisy chaining in this tutorial

http://zone.ni.com/devzone/cda/tut/p/id/7400

but want to know if redundancy can also be implemented.

Thanks

Thanks a lot.

This is what I was looking for.

Hi

I am looking for computer id which we also see in Licence manager.( 16 digit)

my os is windows.

Thanks

Hi

How can I retrieve computer id of my system in Labview, programatically.

Thanks

Vinamra

This is awesome....

Exact what i was looking for.

Hi

I have a software which pops up a window where the name of the file is to be written in the pop up. This window is similar to one we get if we do not give a file path in our FILE I/O functions in Labview.

Is there some way Labview could know whenever this window pops up because of the third party software

Thanks

Vinamra.

Hi

Can I connect Labview with SAP. If yes, is there some material or document I can use for help.

Thanks

I am acquiring signal from an accelerometer and want to integrate it to get velocity in signla express.

I could not find and integration function in signal express 2.5.

Is there some way of doing it.

Thanks

Hello ,

I am working on cRIO and wish to know this about FPGA.

What is the base clock of a FPGA chip( 40 MHz or 200 MHz).

If 40 MHz is base clock then how is 200 MHz derived from it. ( I mean ho we divide one clock tick into 5)

Awaiting a response.

Thanks

Hello

I am using PCI 6711 card and generating dual channel analog output frequecy 100Hz to 10 KHz. I generated sine wave amplitute +-2.5 volts by this card and tested it. I was getting correct value but when I connnect termination resisitance of 50 ohms I start seeing clipping after 800mv.

Can anone suggest me on why this is happenning.

Thanks

HI

thanks a lot.....

I have got the breakthrough..

My program is working now...

I don't have LV right in front of me, but if you drop a property node on the block diagram and attach the Imaq 1394 reference to it you should have exposure time in there somewhere. I can probably post a screen shot tomorrow, if I have time.

HI

I have tried the way as you said..

connected reference from camera to property node..

there were a number of attributes but none was for exposure.

Please send me the screenshot ,it will help me to get a break through.

Thanks for your help

HI

I am using NI IMAQ 1394...

Can you please tell me which VI or function is to be used to control .

Thanks for lasr reply

Are you controlling your camera with NI-IMAQ 1394? If so, exposure time is a property that is controllable in labview. If not, you'll have to control exposure time using a camera vendor supplied DLL or SDK.

Hi

I am using a firewire camera to make a movie and analyse in real time

I have to decrease the exposure time to 1/64 sec.

Is there any vi using which I can change the exposure time manually or any labview function to adjust the properties of camera .

thanks in advance

Hi

I have to make a VI to acquire image in real time at 15 FPS and find the center of the light spot of the colours RGB by breaking the image in RGB.

I tried and made the attached program but the speed that I get is only 3 or 4 frames/sec, I am using a firewire camera and resolutionis 1024*768.(this resolution is a required)

I attach the vi please guide me about what mistake I am doing.

Thanks

hi

i have to cenvert an image to 3 arrays of RGB.

I have been able to do this much as attched here. I have got a 2d array of cluster.

But I want that I get three 2D arrays of R G and B..

is there some function by which I convert a 2d array of cluster(3 elements) into three 2D array of individuals colours

thanks

HI

I have a full version 8.0 of labview and want to use the vision utilities which fall under vision and motion.

However I see this function:

Color Utilities Palette

(Vision-->Vision Utilities...)

IMAQ Color Image To Array

the documentation says that tehre are other function salso which convert a 2D array t o image and some other functions.

I tried but didnt find it and also tried to see if some more CD need to be installed.

Please help me in finding out these functions

Thanks

Hi

Thanks

I have seen it and finally my Vi is working

.

HI

I have tried a block diagram from a NI site to run a firewire camera however after making the blockdiagram.I get the following error on running the program.

"NI IMAQ IEEE 1394:(Hex 0xBFF68008)feature not present in the camera.

I am not sure what thi smean and what is the problem.

I am using a firewire camera by "IMAGING SOURCE"

the link is as follows

http://zone.ni.com/devzone/conceptd.nsf/we...&node=201714_US

the camera is working as the camera is giving image in vision assistant.

thanks
