UDP Sockets Profile
Overview
The UDP profile configures a serial port to broadcast UDP data to systems and/or receive UDP data
from systems.
Functionality
When you configure
UDP
, you are setting up a range of IP addresses and the port numbers that you
will use to send UDP data to or receive UDP data from.
When you configure UDP for
LAN to Serial
, the following options are available:
z
To send to a single IP address, leave the
End IP Address
field at its default value (
0.0.0.0
).
z
The IP address can be auto learned if both start/end IP address are left blank/default.
z
If the
Start IP Address
field is set to
255.255.255.255
and the
End IP Address
is left at its
default value (
0.0.0.0
), the IOLAN will accept UDP packets from any source address.
An example UDP configuration is described based on the following window.
The UDP configuration window, taken from the DeviceManager, is configured to:
z
UDP Entry 1
All hosts that have an IP address that falls within the range of
172.16.1.1
to
172.16.1.25
and listen to
Port
33001
will be sent the data from the serial device in UDP format. The serial
device will only receive UDP data from the hosts in that range with a source
Port
of
33001
. The
IOLAN will listen for data on the port value configured in the
Listen for connections on UDP
port
parameter.
z
UDP Entry 2
All UDP data received from hosts that have an IP address that falls within the range of
172.16.1.20
to
172.16.1.50
and
Port
33010
will be sent to the serial device. The IOLAN
will not send any data received on its serial port.
