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
