Bridging enterprise application with shop-floor

Introduction

- Enterprise applications (EA) are playing important role in current enterprises.

- Rely more on IT systems for Business processes and decision making

- Service Oriented Architecture (SOA) is a paradigm widely employed in EA to increase reusability of its components.

- Nowadays, dissimilar implementations of SOA exist even in Factory level. Enterprise Service Buses (ESB) are commonly Message-Oriented Middleware used to cope with this situation.

Bridging enterprise application with shop-floor 4

Motivation• Current enterprise integration solutions are based on powerful

Enterprise Service Buses (ESB). But with poor support for shop-floor integration.

• Bridging the shop-floor with other intra-logistical layers should extend the system borders and thus provide a more complete visibility of the overall enterprise activities.

• State-of-the-art ESB and application servers are using the modular deployment offered by the OSGi framework to manage the lifecycle of the deployed applications.

• DPWS over OSGi is hence a promising option for interfacing the shop-floor with other heterogeneous systems via ESBs.



Background: PLANTCockpit



The PLANTCockpit project aims to create a reference environment for monitoring, visualizing and analysis of intra-logistical enterprise cockpits.

Project architecture is influenced by the concept of interoperable Function Blocks, IEC-61449.

PLANTCockpit framework lies in the application layer of an ESB.

Adapters

Multiple adapters are developed and within the project scope

DPWS was found to be a suitable candidate for devices and sensors integration.

Concept of DPWS Adapter



The DPWS features:•Dynamic discovery DPWS devices•Retrieve metadata from device hosted services.•Eventing

PLANTCockpit Adapter archetype extends:•Transformation and mapping of messages•Transmission channels for heterogeneous integration•Instantiation and re-configuration of event consumers



Development of DPWS Adapter

• This adapter was developed using a Maven Archetype that generates an OSGi skeleton project of a FB Adapter.

• DPWS Adapter wraps WS4D-JMEDS in an OSGi bundle .



Implementation scenario (1)

Monitor process parameters (Process throughput, energy consumption) of an FESTO MPS 500-FMS.

- DPWS-enabled devices are deployed in each station, generating events regarding the specific station status.

- DPWS-enabled energy meter Inico E10 is employed to measure consumed energy and related parameters.









Conclusions & Future workConclusions:•This implementation can be extrapolated to integrate other protocols and technologies.•Precise performance analysis was not assessed, however smooth monitoring was reached with a message processing frequency of 50 msg/sec using an Intel core i5 Laptop.•This approach allows integrate DPWS devices in OSGi in a non-intrusive manner;•The FB scheme provides high reusability and scalability.

Future work:•Configuration support based on semantic description of services (SAWSDL);•Research towards applicability in time critical systems;•Implementation of possibility for supervisory control and Decision support via DPWS.
