GX Series IO-Link Master Unit

• The host controller 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*1 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 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) *2

Omron's initial offering of IO-Link products includes photoelectric sensors, color mark sensors, proximity sensors and IO-Link masters. By connecting sensors and controllers via IO-Link, all necessary information for satble sensor operations, such as incident light levels, are visible. Now, monitoring and error detection at the sensor level is possible; reducing downtime, aiding in predictive maintenance and decreasing commissioning time.
