Hi,

Unfortunately, now I don't have access to labview. However, there is a vi in the examples which provided with labview, the name of the vi is TCP send/receive as I remember. From the Help menu select find example, in the search tab, search for TCP, go through the examples and you will find a single vi in one of these examples that can send/receive data through the network.

Hope this helps

Dear Zaki,

I am figuring out one of the examples. (actually two data server.vi and data client.vi)

But I totally don't get it:

- data server.vi starts to listen if there is data on the specific port???

- in data server I can't find to which address there is writen, only to a port?

For my opinion it should be:

- On server : select adress and port

- On server : write some data

- On client : select same adress and port

- On client : list if there is data and when there is listen

Hello!

  There are two LabVIEW examples on the distribution disks: "TCP Communicator - Active.vi" and "TCP Communicator - Passive.vi".  It's probably installed in the LabVIEW program directory in the examples folder.

  The TCP Communicator - Active.vi is started on the master PC, then the TCP Communicator - Passive.vi is started on the slave PC.  This allows text to be sent back and forth between the two PCs.

  Both .vi's can be run on the same PC, just start the "Active" first, then the "Passive" next.

  Hope this helps ...

It works like this:

The server listens e.g. on a specified port for someone (a client) to connect.

As soon as a connection exists, client and server can communicate with each other as long as the connection exists. (Just like in real life.)

Guenter, thanks that was the explanation I was looking for!
