Two master modules each use IO-Link 1.1 to communicate digitally with four intelligent field devices: the X20DS438A with IP20 protection and the X67DS438A with IP67 protection for use outside the control cabinet.

The vision advanced by “Industry 4.0”— of work pieces moving independently through the production process and controlling their own production — can only be achieved by expanding sensor technology to make more meaningful data available. Even relatively simple sensors are increasing in intelligence, while digital parameter sets continue to take the place of adjustable potentiometers.

The IO-Link communication standard is a bidirectional digital communication interface that is used in the field to exchange parameter data and diagnostic information. This interface makes it possible to intelligently integrate sensors and switching devices into the control level.
