Reads a binary datagram from a UDP socket. This node returns data when it receives any bytes. When the node receives no bytes, it waits up to the timeout period you specify.
A network connection refnum that uniquely identifies the UDP socket.
The maximum number of bytes to read. You should wire the largest value your application expects. This number must be greater than or equal to the size of the actual datagram. On Windows, if you wire a number less than the size of the actual datagram, LabVIEW returns error 113. On other platforms, the output data is truncated to the requested size.
Default: 548
Time, in milliseconds, that the node waits to complete before reporting a timeout error.
Wire a -1 to this input to wait indefinitely.
Default: 25,000 ms
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Same value as connection ID in.
The data read from the UDP datagram.
Error information.
The node produces this output according to standard error behavior.

The port of the UDP socket that sent the datagram.
The address of the computer where a datagram originates.
