4. 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.

5. 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.

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.

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 work
Conclusions:
•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.
