Thesis Topic (1/3)• Service-Oriented Cross-layer infRAstructure for
Distributed smart Embedded deviceS• Development of a design, execution and management
platform for next-generation industrial
automation systems.• The thesis work provides a system which
integrates different control layers of
the same industrial process:– Wired control– Wireless control– Remote control by the Enterprise Business
Management layer through the Internet

MODBUS
• Messaging protocol• Client/Server communication between
devices placed among different networks/buses• De-facto standard for industrial wired networks• From serial communication lines
to TCP/IP networks• Messages’ format not dependable on the
physical interface• Simplicity, flexibility

Conclusions• Challenges:
– Wired/Wireless protocols interaction – Reliabilty and security of shared common data – Actual plant loops modeling– Parallel control: local, remote (Internet)
• Future developments:– Usage of the communication manager application in a real-life
demonstration– Extensions for supporting other important fieldbuses:
PROFINET, PROFIBUS, Fieldbus Foundation– Tool for user-mapping of shared data between wired/wireless
devices.
