TCP/IP Packets

[vishnu]

Does any one have information on how labview formulates the TCP/IP packets to talk to external slave i/o devices.

All I am trying to do is send bytes to talk to a ethernet driven pneumatic Valve stack through TCP/IP. I am able to open and close the connection to the device.

The only control you have is at the application layer.

The TCP primitives work with binary bytestreams which are represented as a string.

You can convert a byte (U8) array to such a string by using the Byte Array to String primitive which can be found in one of the string subpalettes.

There should be some examples in the example finder (Help>>Find Examples) for doing this.
