B&R X20cBC8083
POWERLINK I/O configuration and firmware update via the fieldbus Integrated hub for efficient cabling Up to 2 slots for hub expansion modules 2x/4x/6x Fast Ethernet hub The bus controller makes it possible to connect X2X Link I/O nodes to POWERLINK. It is also possible to operate the X2X Link cycle synchronously 1:1 or synchronous to POWERLINK using a prescaler. POWERLINK is a standard protocol for Fast Ethernet equipped with hard real-time characteristics. The POWERLINK Standardization Group (EPSG) ensures that the standard remains open and is continually developed:: www.ethernet-powerlink.org. The bus modules expanded to the left allow connection of up to 2 hub expansion modules in addition to the bus controller. Each expansion module is equipped with 2 RJ45 connections. This means that a basic device provides up to 6 hub connections.
