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 serial data to the LAN (using UDP) or receive UDP data from the LAN which will be
forwarded to the serial port.
When you configure UDP for
“LAN to Serial”
, the following options are available:
z
To receive data from a specific IP address, enter this address in the
Start IP Address
field and
leave the
End IP Address
field at its default value (
0.0.0.0
). For the port, you can enter a
specific “source” port or leave as 0 to accept any source port.
z
To receive data from a range of IP address, fill in the
Start IP Address
field with the low IP
address for the range and the
End IP Address
field with the high IP address for the range.
z
To receive data from any IP address and any UDP port, leave the
Start IP Address
field, the
End
IP Address
field and the
Port
field at its default value of 0. The IP address on the first UDP
message received will than be the only IP address accepted from that point on. This is the “auto
learn” feature of the UDP profile.
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. If you
want the IOLAN to receive data only from the first IP address is sees (auto learn the sender IP
address), leave the
Start IP Address
field at its default value (
0.0.0.0
).
When you configure UDP for
“Serial to LAN”
, the following options are available:
z
To send data to a specific IP address, enter this address in the
Start IP Address
field and leave
the
End IP Address
field at its default value (
0.0.0.0
).
z
To send data to a range of IP address, fill in the
Start IP Address
field with the low IP address
for the range and the
End IP Address
field with the high IP address for the range. A separate
UDP message with the same serial data will be sent to each host in the configured range.
