4.3.5 Tank databases of the Rosemount 2460 System Hub and the
Rosemount 2410 Tank Hub
In a typical Rosemount Tank Gauging system, a Rosemount 2460 System Hub collects measurement
data from a number of tanks via one or more Rosemount 2410 Tank Hubs. For proper communication
with the control room PC and the Rosemount TankMaster operator’s interface, Modbus addresses need
to be assigned to the field devices on the tank. These addresses will be stored in the tank databases of
Rosemount 2460 System Hubs and Rosemount 2410 Tank Hubs.
In the tank hub’s database, the Rosemount 2240S Temperature Transmitter and the Rosemount 2230
Graphical Field Display (and other non-level devices
)
are handled as a single Auxiliary Tank Device
(ATD). Two Modbus addresses are used for each tank, one for the level gauge and one for the ATD.
The ATD includes any supported non-level device such as the Rosemount 2240S Multi-Input
Temperature Transmitter and the Rosemount 2230 Graphical Field Display. Other devices such as the
Rosemount 3051S Pressure Transmitter may also be included in the ATD. The ATD address represents all
these devices. Each position in the Rosemount 2460 tank database represents one tank.
In case the level gauge is a Rosemount 5900S 2-in-1, you will need to configure two level device
addresses for the Rosemount 5900S gauge. See the
Rosemount Tank Gauging System Configuration
Manual (Document No. 00809-0300-5100) for a detailed description of how to configure the tank
database with a Rosemount 5900S 2-in-1.
