5 Good Reasons for IO-Link

• Point to point connection with standard sensor /
  actuator cable
• Existing topologies remain stable
• Seamless communication
• Communication of process data and service data
  between sensors / actuators and the control unit
• Mixed operation possible
• Highest compatibility to standard IO
• Fieldbus openness
• Seamless integration into existing networks
• Universal IO interface
• Reduction IO-interfaces in stock
