X20IF2181-2 B&R

POWERLINK V2 for real-time Ethernet communication
Integrated link selector function (preconfigured)
Redundant Managing Node for controller redundancy
Integrated hub for efficient cabling (configurable)
Configurable ring redundancy
Poll response chaining
Dynamic Node Allocation (DNA)
The interface module is used to expand the X20 CPU for specific applications. It is equipped with an POWERLINK interface.

POWERLINK is a standard protocol for Fast Ethernet equipped with hard real-time characteristics. The POWERLINK Standardization Group (EPSG, see www.ethernet-powerlink.org) ensures its openness and continual development.

Systems with redundant cabling can be implemented easily using POWERLINK. Unlike ring redundancy, cable redundancy does not require cable looping, which can sometimes be problematic. This allows the creation of all types of tree structures. When using a device with the link selector function, data is always transferred via the highest quality network lines. The link selector function is integrated in the X20IF2181-2 module.
