Industrial & Optical Ethernet
Industrial Ethernet Networks?
• There is only one Ethernet– 802.3– Ethernet v2
• So what is Industrial Ethernet ( also called rugged or hardened ) ?– The use of Ethernet technology in harsh and
industrial environments vs. benign environment ( also called commercial, business, enterprise, consumer Ethernet)
– The use of Ethernet and TCP/IP as a transport mechanism for industrial protocols
Industrial & Optical Ethernet
Aspects of Industrial Ethernet
• Environment• Operation• Maintenance• Management
Environment
Industrial & Optical Ethernet
Physical Characteristics
• No “standard” Industrial Ethernet switch• Specification must match PLC• Network equipment must not be the weakest link
Industrial & Optical Ethernet
• Marine• Substation• Transportation• ATEX Zone 2
Certifications
Industrial & Optical Ethernet
Environmental Conditions
• Mounting• Form factor• Operating voltage• Temperature• No fans• Vibration• Resistance to EMI• Protection class• Conformal coating
Industrial & Optical Ethernet
Ports
• Number of ports• Speed• Media types• Connectors
Operation
Industrial & Optical Ethernet
Managed or Unmanaged Switches
• Managed– Required for more complex network configurations– High network visibility– Manageability– Ring redundancy
• Unmanaged– Low cost– Low maintenance– Plug and play
Industrial & Optical Ethernet
Network Design
• Office networks– Overbooking– Traditional estimation
• Industrial networks– Non-blocking– Distributed approaches
Industrial & Optical Ethernet
Message Types
• Unicast - message to a single destination
• Broadcast - message to all nodes in a subnet
• Multicast - message to a group of devices
Industrial & Optical Ethernet
Multicast Control
• Ethernet floods multicasts by default• Every end device must process
received multicasts• Multicast control on Ethernet
– IGMP
Industrial & Optical Ethernet
Maintenance
• Device Replacement• Rapid rectification of failures required
– The “Midnight Maintenance Man”– Device replacement techniques– Standardized / Proprietary– Exchangeable memory media– Topology-dependent configuration
Industrial & Optical Ethernet
Management
• Why?– Fault notification and location– Proactive notification of potential
problems
• How?– SNMP– OPC– Profiles
Industrial & Optical Ethernet
Conclusion
• What benefits does Industrial Ethernet bring?– Higher bandwidth– Convergent networking– Cost reduction– Open connectivity– Vertical integration– Standardization
