UDP Write (UDP Write Text) (G Dataflow)

    Last Modified: March 20, 2017

    Writes string data to a remote UDP socket.

    Programming Patterns

    port or service name

    The port or name of the service you want to write to. If you specify a service name, LabVIEW queries the NI Service Locator for the port number that the server registered. port or service name can accept a numeric or string input.



    The address of the computer where you want to send a datagram.

    This input supports scalar strings and unsigned 32-bit integers.


    connection ID

    A network connection refnum that uniquely identifies the UDP socket.


    data in

    The data to write to another UDP socket. In an Ethernet environment, restrict data to 8192 bytes. In a LocalTalk environment, restrict data to 1458 bytes to maintain gateway performance.


    timeout ms

    Time, in milliseconds, that the node waits to complete before reporting a timeout error. A value of -1 indicates to wait indefinitely.

    Default: 25,000 ms


    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error


    connection ID out

    Same value as connection ID.


    error out

    Error information. The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
