Embedded AppKURA is the open source Java and OSGi-based Application Framework for M2M Service Gateways in the Eclipse IoT Working Group.

PurposeSimplify 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

Eclipse Kura seems powerful for my PoC

How can I build my PoC very easily using Eclipse Kura?

Oh no! I have to learn Java and OSGi!

Different People Different Needs

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

Eases developers task -

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

0..n 0..n

0..n Inputs to a Wire Component

0..n Outputs from a Wire 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.

Terminologies - Wire

Logical connections between the Wire Components are known as Wires

Terminologies - Wire Envelope

Abstract data format decoupling Wire Components to have context specific knowledge

Demo

An IIoT Use CaseA 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

Current Status
