16. 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

21. 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 -

22. Our Solution
• without sacrificing much flexibility
• raises the abstraction level
• application logic is simplified to node connections
• extensible
• Eclipse Marketplace Integration
Eases developers

24. Terminologies - Wire Graph
Kura Wires Dataflow Graph known as Wire
Graph

25. Terminologies - Wire Component
Each node in the Wire Graph is a Wire
Component

26. 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

27. Terminologies - Asset
• Enhanced Functional Architecture

28. Terminologies - Asset
Assets are special types of Wire Components that interact with
transducers
For example, Modbus PLC, S7 PLC or OPC-UA
PLC etc.

33. An IIoT Use Case
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

34. Current Status
