This bus controller makes it possible to connect X2X Link I/O nodes to POWERLINK.

Additional X2X Link I/O nodes (X67 modules or other X2X Link-based modules) can be connected using the integrated X2X Link connection. When doing so, it is possible to operate the X2X Link cycle either 1:1 synchronously or synchronously to the POWERLINK network using a prescaler. Mechanically, POWERLINK is connected via an IP67-rated standard D-keyed M12 Ethernet connector.

POWERLINK is a standard protocol for Fast Ethernet with hard real-time characteristics. The Ethernet POWERLINK Standardization Group (EPSG) ensures that the standard remains open and is continually developed:

Ultrafast reACTION Technology makes it possible to control I/O channels with response times down to 1 μs. All of the commands that can be used for reACTION programs are provided as function blocks in special libraries (e.g. AsIORTI). Programming using the standard Function Block Diagram (FBD) editor in Automation Studio is compliant with IEC 61131-3.
