Description
Connecting POWERLINK devices to the POWERLINK cable redundancy systemIntegrated compact link selector function
POWERLINK is a standard protocol for Fast Ethernet with hard real-time properties. The Ethernet POWERLINK Standardization Group (EPSG) ensures that the standard remains open and is continually developed. www.ethernet-powerlink.orgSystems 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 module compact link selector. This makes it easy to connect any POWERLINK device to a redundant POWERLINK network.
