Basic Information
Now it is possible to directly connect digital sensors to CC-Link Contributes to wire-saving, construction-saving, traceability, preventive maintenance, and more
Features
Traceability
By keeping track of the sensor configurations at equipment start-up, any failure that may occur after equipment delivery can be eliminated in early stages.

Remote monitoring of equipment
It is possible to check the sensor configurations through open network when a failure occurs in the equipment or production line, so that the on-site man-hours taken can be kept to the minimum.

Highly efficient maintenance
By having the configurations saved as "Configuration file" before equipment shipment, later on when it comes to exchanging the sensors, the configurations can be simply written in to CC-Link. Also, exchanges can be done easily with connection connectors without any extra tools.

Preventive maintenance
Take in digital data such as incident light intensity or pressure value of sensors and graph them out for preventive maintenance.
(e.g.) Light attenuated due to dirt on fiber sensor.

Reduction of wiring, construction and space
Space for installing a CC-Link slave is eliminated. Cascade connection is simply done by connectors so that the time taken for wiring and construction can be cut down.
