4. Introduction
- Multiple heterogeneous systems with different data granularity can
be found in even in the simplest manufacturing companies (eg:
Resource planning, machines, sensors)
- The variety of heterogeneous systems implies the use of distinct
protocols which contains different data and information models
causing integration complexity which is time consuming.
- For monitoring applications such as: Asset tracking, Asset utilization,
Energy monitoring require correlation of data from these systems.

EU FP7 project PLANTCockpit objectives:
-Visibility and integration across all manufacturing processes, layers,
and systems
-Optimized production and logistics processes
-Increased energy efficiency and reduced waste production
EU FP7 project PLANTCockpit offers:
-A data integration architecture for production
and logistic cockpits.
-Implementation on top of an
state-of-the-art Enterprise Service Bus (ESB)
solution.
-Modular integration components based on a
Function Block scheme influenced by IEC-61499.

Composition

7. Motivation
Previous facts and concepts: “encourages the use of a rich descriptive
language as a modelling and execution language to manage the
exchange of messages and to define the connections among the
services exposed by each FB” [1]
Hence, this work focused in finding a standard description language to
express the data integration scenarios such as the one previously
presented.

Benefit: Avoid the need for a custom language and
configurator for the platform. Reusability of modelling tools
using standard languages.

• The IEC-61499 is a component-based international standard used
for modelling distributed systems.
• Intuitively the most obvious option for this endeavour. However,
system and technology heterogeneity affects its applicability.
Characteristics
• Encapsulates domain logic in FB and modularizes applications with
composite FBs. (CFB).
• Events and data are separated.
• Mapping is done via event/data associations.
• Connections describe source and destination

10. Web Service – Choreography description
language (WS–CDL)
• WS-CDL is a Candidate Recommendation of the W3C.
• Describes the collaboration between participants in a WS
composition for accomplishing a common task in a distributed
manner.
• Parts of WS-CDL in a WS composition:
– Static Part  Description of invariant collaborating participants used in
dynamic part: Role, Participant, Relationship and Channel Types
– Dynamic Part  Description of interactions between Role Types:
Ordering Structure, WorkUnit and Basic Activity (Interaction, Assign,
NoAction, SilentAction, etc.)

12. Conclusions and further work
• CDL provides a richer language for modelling interactions
• Unfortunately CDL has little support as an execution language.
• For FB based enterprise integration, as demonstrated within PLANTCockpit,
the selection of CDL over IEC-61499 seems to be a more suitable, since is
more expressive for modelling interactions, roles and relationships. This is a
very important property since branding a FB with roles and the interaction
with relationships encourages more the reusability and re-configurability of
components.
• Further work aims to define a FBN deployment language.
– Not only interactions between already deployed FB instances, but deployment of instances
as well.
