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
