The contrast sensor DK12 with an IO-Link interface makes continuous communication with the diagnosis system and the parameter assignment up to the sensor level available for the first time. That way it is ensured that the intelligence which is already integrated in each DK12-contrast sensor, is harnessed to the full. This will offer a number of special advantages during service (remedial action, maintenance und device exchange), commissioning (cloning, identification, configuration and localization) or during operation (change of job, continuous parameter monitoring und online diagnosis).
