Differences between industrial and ofce Ethernet
Ofce Ethernet
• Fixed building installation
• Variable connection options
• Pre-assembled connection cables
• Star topology most widely in use
• Large volume of data
• Mid-level network availability
• Mostly only acyclical transmission
• No real-time characteristics required for standard
applications
• No extreme conditions
Industrial Ethernet
• Individual plant-inuenced networks
• Robust component characteristics
• On-site, user assembly connections
• Redundant network topologies (ring)
• Small data packets (measurement values)
• Very high network availability
• Extremely high real-time requirement
• Mostly cyclical transmission
• Extreme temperatures
• Dust, dirt, splashing water, oils gases,
• Vibration, electromagnetic elds
• Risks of danger and damage from mechanical or
chemical inuences
