• 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 .
