net_ctrl packet from FlightGear
Animation/Flight Simulator Interfaces
The Receive net_ctrl Packet from FlightGear
block receives a network control and environment data packet,
from the simulation of a Simulink® model in the FlightGear simulator,
or from a FlightGear session. This data packet is compatible with
a particular version of FlightGear flight simulator. All the signals
supported by the FlightGear
net_ctrl data packet
are supported by this block. The signals are arranged into multiple
groups. Any group can be turned on or off. Zeros are inserted for
packet values that are part of inactive signal groups.
In Rapid Accelerator mode, if you run a model that contains
this block , the block produces zeroes (
does not produce deployable code. In Accelerator mode, the block works

To determine the source IP address, you can use one of several techniques, such as:
Use 127.0.0.1 for the local computer (localhost).
Ping another computer from a Windows®
cmd.exe (or Linux® shell)

Select your FlightGear software version:
Note: If you are using a FlightGear version older than 2.0, the model displays a notification from the Simulink Upgrade Advisor. Consider using the Upgrade Advisor to upgrade your FlightGear version. For more information, see Supported FlightGear Versions.
Enter a valid IP address as a dot-decimal string. This IP address must be the address of the PC from which FlightGear is run.
10.10.10.3. You can also use
a MATLAB expression that returns a valid IP address as a character
vector. If FlightGear is run on the local PC, leave the default value
UDP port that the block accepts data from. The sender sends
data to the port specified in this parameter. This value must match
the Origin port parameter of the Generate Run Script block. It must be a
unique port number that no other application on the PC uses. The site,
lists commonly known UDP port numbers. To identify UDP port numbers
already in use on your PC, type:
netstat -a -p UDP
Specify the sample time (-1 for inherited).
Enable a received flag output port. Use this check box to determine if a FlightGear network packet has been received.
