[dhiraj03416]

hi all
we had recently brought an instrument which has its dll wriiten in c language.i want to use it in labview.we are not able to connect to the instrument also.it has only lan .& i suppose its not taking the ip address & the port no.
to which format should i give them as they are structures which are passing to a function & i am calling that dll in the labview.
regards

Hi dhiraj034...,

you can use the import function of LabView to create the vi´s you need to communicate with your device, or you write them by yourself.

What is the instrument?

Who is the manufacturer, and the model designation?

If you provide these, I can check to see if some drivers already exist for it.

Hi!
   I would focus on this problem, which is the first to be solved.  How can you say that's not taking ip address? do you have a DHCP server enabled? Also I'd check firewall settings...

PS.: of course, these are "blind" suggestions, I'd like to have your instrument on my desk to try....
