"USB":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann proprietary software by using the USB interface.

"Ethernet fieldbus"

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface.

"Ethernet fieldbus + Ethernet diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface or Ethernet fieldbus interface.

"Ethernet diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface.

"Ethernet diagnostic + Modbus TCP diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software or via Modbus TCP by using the Ethernet diagnostic interface.

"Ethernet fieldbus + RS 232":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface or by using an adapter cable via RS 232 interface.


"RS 232":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using an adapter cable via RS 232 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.

via ASi
ASi connection

the connection to ASi as well to AUX (auxiliary 24 V power) is made via yellow resp. black ASi profile cable with piercing technology or via M12 socket (in IP20 via clamps).

clamps
ASi address

AB Slave (max. 62 AB Slaves/ASi network), 2 AB Slaves (max. 31 modules with 2 AB Slaves), Single Slaves (max. 31 Single Slaves/ASi network), ASi-5 Slave (max. 62 ASi-5 Slaves/ASi network), mixed use allowed.
For modules with two slaves the second slave is turned off as long as the first slave is addressed to address "0".
Upon request, slaves are available with specific ASi Slave profiles.
