POWERLINK
What is POWERLINK?
Ethernet POWERLINK is a software-based real-time Ethernet solution designed to transmit real-time data in the microsecond range. POWERLINK enables devices from different manufacturers to communicate with each other without the need for special interface adaptations. The Ethernet solution is primarily used for the transmission of process data in automation technology. Ethernet POWERLINK was originally developed by B&R Industrial Automation and is now being further developed and specified as an open standard by EPSG (Ethernet Powerlink Standardization Group) – an open user and vendor group.

POWERLINK Gateways
POWERLINK ASi Gateways
ASi POWERLINK gateways in stainless steel provide an interface for a POWERLINK fieldbus. The certified ASi Gateways are available in different versions with IP20 protection class, e.g., with integrated decoupling, OPC UA interface and integrated web server for easy diagnostics and maintenance.

Safety, POWERLINK ASi Gateways
The certified ASi gateways with integrated safety monitor are available in different versions with protection class IP20. All gateways feature the Safe Link technology, which makes it possible to connect different system components easily and flexibly. A product variant with integrated openSAFETY communication is also available.

1 ASi power supply per ASi network. | Access to ASi master and safety monitor via own software from Bihl+Wiedemann using the diagnostic interface (e.g. USB, RJ45, RS232). For certain devices with Ethernet-based fieldbus (PROFINET, EtherNet/IP), there is also the option of diagnostics and configuration directly via the fieldbus interface.
The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device. | Safe inputs can be configured as 1-channel or 2-channels depending on the desired application or PL and SIL level.
