14. Siemens Wind Power Distributed Control
• Wind turbine farms can include 500
turbines, 100m blades
• Gust control across the array
requires fast communications with
dynamic, selective filtering
• DDS enables large, distributed
intelligent machines

15. Grand Coulee Dam
• DDS controls the 6.8 GW Grand Coulee Dam
–Largest power plant in North America
–Fastest-responding major power source on the
Western Grid
• RTI system live since Jan 2014

16. Audi Hardware-in-the-loop simulation
• Audi hardware-in-the-loop simulation feeds
realistic data to components for testing
• The system offers plug-n-play between
simulation vendor solutions
• RTI software enables a modular test environment
that scales to work with hundreds of devices

17. RTI Connext DDS deployed across Navy Systems
• Most US and NATO Navy systems
–Lockheed Aegis
–Raytheon DDG 1000
–Raytheon SSDS
–LCS (Lockheed and GDAIS)
–Raytheon LPD-17
–Many more, US and allies
• Highly distributed systems include
radar, weapons, displays, controls
• Standards-based, high-performance
middleware breaks vendor lock-in,
drives interoperability ,and future-
proofs the architectural design

18. GE Transportation
©2017 Real-Time Innovations, Inc.
GE Transportation freight and
passenger locomotives require safe
and reliable control, signaling, and
communications
The system is being developed using
SysML, Simulink, and DDS

19. MagicDraw Plug-in for Connext DDS

20. DDS development with
OMG standards
DDS-XTYPES and IDL4
• Logical Data Model and Service Interfaces
• Portable: Language-Independent Type System
• Safe: Rules for Type Compatibility
• Flexible: Types/Interfaces expressed in IDL or XML
• Dynamic API’s to access data and types
• Systems that adapt at run-time
• Efficient binary serialization
@mutable
struct TemperatureType {
@key string name;
@range(-50, 50) float currTemp;
};
/* Service definition */
enum TemperatureScale {
CELSIUS, FAHRENHEIT };
@service
interface Thermostat
{
float setCutoff(float temp)
raises (TooFast);
float getCutoff();
};

21. DDS development with
