Data Aggregation
Consistent data via open standards
● OPC-UA - a communication protocol for industrial automation
○ Eclipse Milo is a Java implementation of an OPC-UA stack,
including client and server
● MQTT - general purpose messaging protocol for IoT
○ Eclipse Paho provides MQTT client libraries (Java, C/C++,
JavaScript, Python, etc)
○ Eclipse Mosquitto provides MQTT broker implementation

Production Performance Management Protocol (PPMP)
PPMP / Eclipse Unide
⇒ consistent data format for machine data

Data Aggregation
PLC Development
- Existing systems are often closed
and proprietary systems
- Difficult to create flexible
manufacturing processes with
existing PLC environments
- New standards allow for more open
and distributed development (IEC
61499)

Device Management
Remote update and configuration of devices
important for scalability and security.
OMA LightweightM2M (LWM2M) provides a device
management standard
Eclipse Leshan and Eclipse Wakaama implement
LWM2M

Device Management - Software
Update

Security
● Code signing for Edge computing
○ Eclipse Kura allows for code signing of deployed
code
● Authentication of devices
○ Eclipse Hono and Eclipse Hawkbit provide device
authentication
● Access control
○ Eclipse Keti provides a framework for implementing
granular authorization mechanisms to access data
and services

Data Management and Analysis
- NoSQL Store
- Integration with Cloudera and others
● Microservice approach for IoT services
● Well defined REST API
● Allows for easier integration of other services

Digital Twins
Eclipse Ditto: Device-as-a-Service
- A unified resource-based API that can be used to
interact with devices
- Abstracting from the complexity of different device
types and how devices are connected
- State management for physical devices
- Device and sensor properties like temperature,
location, level, fault information, etc.
Configuration properties of sensors and actors like
thresholds, intervals, ranges, toggles and limits, etc

Digital Twins

Great! But…
where should
I start?

Industry 4.0 Testbed
Problem Statement
→ Industrial equipment deployed on factory floors
today use a wide variety of protocols that allow
them to be controlled and expose their condition
→ It makes it hard to process production
performance data in an efficient way, and virtually
impossible to implement Industry 4.0 practices
such as predictive maintenance.

Proposed solution
PPMP*

consumption
temperature
vibration
RPM

* PPMP = Production Performance Management Protocol
REST
API
Monitoring
Dashboards
Predictive
Maintenance
Bridge heterogenous
systems (Modbus, OPC-UA,
…) to a common data
model
Expose consolidated
performance data over
standard APIs for integration
with 3rd party systems
