• The NXILM-400 is a host controller that can cyclically read control signals, status, wiring, and power supply status of IO-Link sensors.
• User-specified data in IO-Link devices can be read and written from the host controller when necessary.
• Digital signals can be input rapidly from IO-Link sensors* during IO-Link communications.
• IO-Link sensors can be combined with non-IO-Link sensors.
  Incorrect connections of IO-Link sensors can be checked when IO-Link communications start.
• Backup and restoration of IO-Link device parameters*2 make replacement of IO-Link sensors easier.
• Sensors can report their errors to the NXILM-400 master, which facilitates locating errors from the host.
• The total number of retries in cyclic communications can be recorded to check the quality of IO-Link communications. (When EtherCAT is used as the host communication   interface) **

           *IO-Link sensors that support digital inputs with pin 2.

           **When the Omron IO-Link master united is used.
