• DeviceNet
• product information (PDF)

■ Application range

• Stationary application
  
• DeviceNet™ connects industrial devices e.g. limit switches, photoelectric switches, valve islands, motor starters, drives, PLCs, etc.
  
• DeviceNet™ Bus system (Rockwell Automation)
  

■ Product features

• Based on proven CAN (Controller Area Network) technology.
  
• Permissible cable lengths vary with the data rate and the cable thickness
  
• THICK cable total trunk length
  125 kbit/s = 500 m
  250 kbit/s = 250 m
  500 kbit/s = 100 m
  
• THIN cable total trunk length
  125 kbit/s = 6 m
  250 kbit/s = 6 m
  500 kbit/s = 6 m
