3 Internet today: connecting computers INTERNET Smartphone or tablet devices serve as medium between us and the cyberspace M.Sc. Henning Trsek Forum Industrial IT

4 Internet tomorrow: connecting things INTERNET M.Sc. Henning Trsek Forum Industrial IT

5 Things: PLCs, devices, smart factory, INTERNET M.Sc. Henning Trsek Forum Industrial IT

6 project EU funded project Duration: 3 years Approx. 3.5 Mio Funding (Total Budget ~ 5.9 Mio ) Started in June Partners from Industry and Research Vision IoT Enabling Agile Manufacturing Systems Project coordinator network & security Security Configuration Management Scenarios & requirements pilot Software engineering & middleware aspects Software engineering system modelling Automation & engineering M.Sc. Henning Trsek Forum Industrial IT

7 IoT in automation General Goals for Automation Reduce engineering costs Reduce maintenance costs and system downtime Increase flexibility and reduce re-configuration costs Reduce infrastructure costs Requirements Decoupling of applications and underlying infrastructure Industrial performance & reliability Scalable to thousands of devices Dependable and predictable = (Reliable communication) + (Secure Plug&Play) + (Web-technologies) M.Sc. Henning Trsek Forum Industrial IT

8 approach and architecture Application services Abstraction Context Composition Application semantics Network services Device semantics Network management Auto configuration Today Tomorrow Application Static mapping Real-time Network Application Application level Middleware services Statisches Middleware Mapping Device and network embedded services Static coupling of application and network Decoupling application and network Real-time Network M.Sc. Henning Trsek Forum Industrial IT

9 Plug-and-play in office IT systems (e.g. USB) 3. Application 2. Operating System 1. Connectivity M.Sc. Henning Trsek Forum Industrial IT

10 How to achieve Plug-and-play (PnP)? Identification of required signals Automatic variable assignment Usage of semantics Detection of devices Adding or removing of devices New devices must be configured automatically. Autoconfiguration of RTE Automatic RTE configuration when devices are added or removed Application Application level Middleware services Middleware Device and network embedded services Real-time Network M.Sc. Henning Trsek Forum Industrial IT

11 Approach Automatic Discovery & Configuration Discovery using DPWS PnP-enabled generic RTE devices RTE-specific methods for standard devices Discovery using OPC UA PnP-enabled generic RTE devices RTE specific configuration service M.Sc. Henning Trsek Forum Industrial IT

12 Autoconfiguration steps Controller IP allocation service Device DDF Server IO-Device connected Requests IP-Address Assigns IP-Address Ad-hoc channel Discovery OPC UA discovery Controller retrieves Device Description File Configuration Information exchange Controller parses Device Description File Controller sets device parameters and configures RTE M.Sc. Henning Trsek Forum Industrial IT

13 Proof-of-concept: Profinet autoconfiguration Using an additional ad-hoc channel for configuration purposes Examples: Discovery, Management, Notification Our solution approach: Configuration service with OPC-UA Usage of GSD information M.Sc. Henning Trsek Forum Industrial IT

14 Video: PnP demonstration M.Sc. Henning Trsek Forum Industrial IT

15 World-wide smallest OPC-UA server OPC UA Services Nano Embedded Device Server Profile Read, Browse OPC UA Information Model Simple sensor data Basic device information Footprint (15 kbyte) OPC UA Stack: 10 kbyte Micro TCP/IP stack: 5 kbyte M.Sc. Henning Trsek Forum Industrial IT

16 OPC-UA at chip level enables Internet of Things One of the smallest OPC-UA server Easy software integration for simple devices Internet of things enabled Very resource limited devices supported Smart sensors with integrated communication interface Vertical integration Platform specification: TPS-1 Chip, Available memory < 64 Kb Operating system: EmbOS Connectivity: Ethernet (two port switch and non real-time TCP/IP channel parallel with a real-time channel) M.Sc. Henning Trsek Forum Industrial IT

17 How to achieve Plug-and-play (PnP)? Identification of required signals Automatic variable assignment Usage of semantics Detection of devices Adding or removing of devices New devices must be configured automatically. Autoconfiguration of RTE Automatic RTE configuration when devices are added or removed Application Application level Middleware services Middleware Device and network embedded services Real-time Network M.Sc. Henning Trsek Forum Industrial IT

18 Application services (related research) Concept of a semantic language Formal description language for modules and devices Informationmodel Mapping (log./phy.) Connectivity Funktion Signal Measurement Control Attribut Sensor, Actuator, N/A Position, Temperature, Voltage, etc. Motor, Valve, Linear Axis, etc. Neighborhood Previous system, next system M.Sc. Henning Trsek Forum Industrial IT

19 LMF as validation platform Adaptability / Flexibility Concepts Energy efficiency Model based diagnosis Teleoperation (M2M-Integration) Control and field level SCADA System Control Room M.Sc. Henning Trsek Forum Industrial IT

20 Vision: PnP in the Lemgoer Modellfabrik M.Sc. Henning Trsek Forum Industrial IT Lemgoer Modellfabrik

21 Conclusion and outlook Conclusion Plug-and-play at different levels Application, Middleware, Network Autoconfiguration of RTE Proof-of-concept for Profinet IO as RTE Application level Semantics Devices and modules Information and functionalities as services Outlook Further investigations at the application level Platform independent standard needed M.Sc.
