4.23.25.1 General information
The X20IF2181-2 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 with hard real-time properties. The Ethernet POWER-
LINK Standardization Group (EPSG) ensures that the standard remains open and is continually developed.
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 (see 4.23.25.9
"POWERLINK cable redundancy system" on page 1866).
