Tankbus

The devices on the tank communicates with the Rosemount 2410 via the intrinsically safe Tankbus. All field devices in the Raptor system have built-in communication modems for FISCO FOUNDATION fieldbus (FF) communication and will automatically communicate with the 2410 when connected to the Tankbus.

Optional Secondary Bus

In addition to the Tankbus an optional intrinsically safe bus is available for communication with devices not compatible with FOUNDATION fieldbus. It allows you to connect devices for intrinsically safe HART 4-20 mA analog input/output communication.
