Description

Send a UDP packet to a network address identified by the remote IP address and remote IP port parameters.

Note

If you are having trouble using UDP to communicate with a computer, investigate whether antivirus or firewall software might be blocking UDP traffic. If so, try reconfiguring the software to allow UDP traffic for a specific IP port number.

Ports

Input

Port_1 — Input port to accept data

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

Parameters

Remote IP address (‘255.255.255.255’ for broadcast) — Remote IP address of the remote host

127.0.0.1 (default) | scalar

Enter the address or hostname of the IP node on the remote device.

To broadcast the UDP message to all devices, use the default parameter value, '255.255.255.255'. Use this approach sparingly to avoid creating unnecessary broadcast traffic. Often, IP routers are configured to drop broadcast UDP packets sent to '255.255.255.255'.

Remote IP port — Remote IP port number of the remote host

25000 (default) | scalar

The number of the IP port on the remote device, which can range from 1 to 65535. This value defaults to 25000.

Local IP port source — Local IP port source from which the block sends data

Automatically determine (default) | Specify

Select this option to determine the local port source from which the block sends the data.

Local port — Local port from which the block sends data

2048 (default) | scalar

Enter the local port from which the block sends the data to the remote host.
