B&R X67BC81RT.L12
POWERLINK reACTION Technology module Integrated hub for efficient cabling 4 digital inputs 5 digital channels, configurable as inputs or outputs 2 analog inputs ±10 V 1 analog input ±10 V 1 ABR incremental encoder input 5 V 5 V and 24 V encoder power supply integrated in the encoder connector I/O configuration and firmware update via the fieldbus Integrated connection to local expansions via X2X Link for 250 additional modules Cycle time configurable starting at 200 µs for local expansions 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. Additional X2X Link I/O nodes (X67 modules or other modules based on X2X Link) can be connected using the integrated X2X Link connection. Mechanically, POWERLINK is connected via an IP67-rated standard D-coded M12 Ethernet connector. 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. 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.
