• POWERLINK V1/V2

• 8 digital channels, configurable as inputs or outputs

• I/O configuration and firmware update via the fieldbus

• Integrated connection to the local expansion via X2X Link for up to 250 additional modules

• Configurable I/O cycle (starting at 200 µs)

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 .
