GE Intelligent Platforms
September 2015
AGENDA
• OPC UA: Enabling Industrial
Internet
• OPC & OPC UA – Key components
• GDS (Global Discovery Server)
• Conclusion

The Industrial Internet
• Entertainment is digitized
• Social marketing emerged
• Communications mobilized
• IT architecture virtualized
• Retail and ad transformed
• Monitoring to component levels
• Predictive maintenance
• Energy and fuel efficiencies
• Virtualized operations technology
• Workforce transformation

Utility Specification
• Device configuration is time
consuming
• Legacy installs make it even more
complicated
• To keep this information up to date is
very difficult over time
• Certificate Management is an
unknown concept for many
Why a GDS?*Global Discovery Server
GE Global Discovery Server (GDS)Based on part 12 of the Specification
1. Server discovery
• Local discovery and global discovery
• Compliant servers broadcast their endpoints
• Provide list of available endpoints to clients for ease of configuration
2. Certificate management
• Acts as a certificate authorityand store for UA client andserver connections
• Facilitates the exchange ofcertificates to enable easierconfiguration
Before and After OPC UA and GE GDS
BEFORE AFTER
Manual entry of end point addressesAutomatically locate devices quickly and
easily throughout the site
Certificate Management was painful
– time consuming
Facilitates the exchange of certificates on
behalf of the user
Manual synchronization of certificatesTake advantage of existing authentication
services
Some devices cannot talk (“headless”)!Implements push/pull for client/servers
– Device initialization
Reduces implementation costs & overall lifecycle costs
Even if your devices don’t talk OPC UA …they can still communicate
• Leverage a GE gateway
(Agent) to secure your
system even without GDS
aware devices
• Agent populates the device
directory on behalf of the
Server
• Manages certificate
exchange for UA servers
Continuing theJourney toSelf-ConfigurationManaging Systemswithout IT Support
• Plug and play user experience to
provide faster time to solution and
value – reducing costs
• Model for configuring smart devices
• Integrated user experience for control
and HMI/SCADA
• Integrated user experience for
heterogeneous hardware

Reducing Costs and Saving Timewith Greater Interoperability
• Modularity enables architectural flexibility and cloud
assisted design
• Consistent interoperability enables a better experience
• Data server provides scalability and flexibly to leverage new
devices and bring forward existing investments
• New tools built on this foundation
will provide new value for
automation solutions
