Basic Vision for Siemens Plant Cloud Services: open cloud platform

Open cloud platform• Open standard (OPC) for connectivity of Siemens and

third-party products

• Plug and play connection of Siemens products (engineering in the TIA Portal)

• Cloud for industry with open application interface for individual customer applications

• Siemens industry apps: asset analytics, energy analytics, industrial network analytics, etc.

Real use case: Chinese SMEs see plant data service as essential for their business development

Pilot partner: OEM Partner for Car Assembly Line

Pilot Background/Objective1) New business model, Production Line as a Service:

Transparent pay-per-use pricing modelOpportunities for completely new business models (e. g. selling machine hours)

2) Technical needs: Reliability guarantee; Reduction of maintenance cost; Reduction of the spare part stock for maintenance;

Facts & Figures• Automotive production line equipment provider with big market

share • About 30% of the orders have service contract attached (1 year

service after installation)

Requirements and Opportunities for Chinese SME

Requirements: 1) Besides reliable product/system, remote data driven service, e. g. preventive maintenance, has been identified as a

key business driver and differentiator by many Chinese SMEs.

Key Challenges in Real Project Deployment

Lack of digital site description: have to rely on Visio, photos and talk

Manual configuration for data acquisitionTricky trigger definition:Need to capture right data at the right time

Manual data analysis:Dashboard and report are manually done

Modeling Tool: Basic Idea

Domain specific templates are prepared as semantic model through the demo case;

Templates and generated model can be imported and exported as XML/RDF files;

Next step: Import standard templates model, for example through PLM software

Knowledge Based Automatic Analytics and Report Generation

Use of knowledge base:

Automatic analytics for the motor health status by the knowledge of force transmission;

Automatic diagnostic report generation with root cause identification;

Conclusion

Big market from Chinese SMEs for plant data service

Threshold and efforts for project specific engineering works must be reduced for repeatable solution

Semantic technology plays an important role for modeling & analytics to simplify the project specific engineering works
