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

Networks (2/2)

• Wireless network protocols:– IEEE 802.11(1997/a/b/g/n)– IEEE 802.15 (Bluetooth - ZigBee)– IEEE 802.16 (WiMax)– WirelessHART

WirelessHART• First open wireless communication standard designed for industrial

environments• Reliability: mesh networking, channel hopping, time-synchronized messaging• Security & Privacy: encryption, authentication, verification, key management • Effective power management: smart data publishing• Self-organizing ability through three steps: advertising, joining, scheduling

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.
