Embedded App
KURA is the open source Java and OSGi-
based Application Framework for M2M Service
Gateways in the Eclipse IoT Working Group.
Purpose
Simplify the design, deployment and remote
management of embedded applications.
It provides
• Cohesive and integrated app environment
• Modular software components
• HW abstraction layer
• Field protocol libraries
• Cloud connectivity
• Remote app and device management
• Local app and device management
• Development tools

Kura’s Benefits
Kura helps Customers focusing on their core competences (Customer‘s differentiators),
by supplying highly integrated modular, common building blocks.
This approach provides partners with a competitive advantage by ensuring:
• Reduced development time → Shorter time to market
• Less required resources → Reduced development costs
• Hardware virtualization → Better investment protection
• More deterministic project execution → In time market introduction
• Focus on the application → Differentiate your offering and products
• Portable, robust code → Higher quality software
• Standard based → Future-proofed, Investments protection
• Remote app management → Extended product lifecycle

Solution
Approach ... Dataflow Programming
…
• have inputs and/or outputs
• produce outputs
• consume inputs
• abstract underlying logics
• highly reusable and portable
Application Logic is expressed as a directed graph
Nodes -
Our Solution
• without sacrificing much flexibility
• raises the abstraction level
• application logic is simplified to node connections
• extensible
• Eclipse Marketplace Integration

Terminologies - Wire Graph
Kura Wires Dataflow Graph known as Wire
Graph
Terminologies - Wire Component
Each node in the Wire Graph is a Wire
Component
Terminologies - Wire Component
Wire Component can be a producer of data and/or a consumer of
data
Wire Component

Component
Wire Components don’t need to have context specific knowledge about
each other
Terminologies - Asset • Enhanced Functional Architecture
Terminologies - Asset
Assets are special types of Wire Components that interact with
transducers For example, Modbus PLC, S7 PLC or OPC-UA
PLC etc.

A newly installed part of a plant based on Modicon PLC running Modbus RTU,
connected to an Industrial Service Gateway and pushing data to Cloud instance
Control operator intends to monitor the Modbus Device connected sensors’
data and change the statuses of the connected actuators using a dashboard
