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 Vinamra

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. :thumbup:

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 Vronto

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 Vronto

HI thanks a lot..... I have got the breakthrough.. My program is working now... regards Vronto

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 vronto

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

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 vronto31

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.

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 Download File:post-5265-1151068914.vi

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 . regards

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 Download File:post-5265-1149770755.vi
