B&R has achieved an intelligent sensor/actuator by integrating IO Link in the X20 System using the X20 digital module DS4387.
All four channels are IO Link channels, but can also be used as
standard inputs or outputs. The specified 3-line connection can be
implemented using the connector system with 12 terminal points per
module that is only available with X20. All specified baud rates are
also supported. The component density of X20 saves space compared to
conventional I/O systems.
