how to bring data from ethernet cable to LabVIEW?

[venkat04]

I want to interface enthernet cable with labview and wan to use the values thro enthernet in labview??? is that possible??? if it is, please reply...

Yes it is possible. There are a few ways to communicate TCPIP and UDP are the two easiest ways. You will need an SDK for what ever you are going to talk to and you will also need the programming symtax to talk to the device as well as the port ID and the IP address of the device you are talking to if it come with a set IP address.

It would also be really nice if you said what the Ethernet cable is connected to (pc, instrument, etc). Pretty hard to give any kind of details without this vital piece of information.

the ethernet cable is from microcontroller..... i want to control the single parameter through microcontroller in the field and transfer the information through the ethernet and monitor the process using LabVIEW and control using authentication....... can u help me with that.......

Do you have the SDK for the micro controller so you know how to communicate to it?

wat did u mean by SDK??

Software Developers Kit

Most companies will provide an SDK for software developer that gives them everything they will need to use their hardware. If you do not get this then the road is much harder and you will have to figure out everything on your own.

If you did not get an SDK then I hope you got a sample program. If so then you can use a packet sniffing program to reverse engineer this system. This is a much harder way to go and you usually do not get all of the functionality from the system.

You need to know the communication telegram syntax of the microcontroller.  You need to find out what telegrams you need to send to your microcontroller to query it, and what telegrams to expect on return.

Once you know this, you can send and receive data telegrams over ethernet using TCP send, TCP read etc.
