Hi,

  I have DMM4040 and am using Labview2010 version..I have the DMM to connected to my pc, and while running the program if i lost the communication between the DMM and my pc, how can i recognize and solve it..

  I need to display a error pop up message if there is no communication, so that i can stop my program from running.

Surely you are using the error in/error out connections?

You can use timeout to check whether communication is happening or not? When timeout occures then you can say error.

One more thing, I dont know your application but if possible when first time timeout occured then try one or two more time before you say error in communication.
