Rosemount Raptor
Example 2: several Tanks connected to one 2410 Tank Hub
This example includes three tanks, each of which has one Rosemount 5400
Radar Level Transmitter and one Rosemount 2240S Multi-input Temperature
Transmitter. All tanks are connected via the Tankbus to the same Rosemount
2410 Tank Hub. The 2410 Tank Hub is connected to a TankMaster PC via a
2160 Field Communication Unit.
For each tank the Modbus addresses of the 5400 and other devices have to
be entered in both the 2160 FCU Slave Database and the 2410 Tank
Database.
The 2240S and other non-level devices are handled as a single ATD device.
In this example the 2410 Tank Hub serves three tanks. For Tank Position 1 in
the 2410 Tank Database the ATD Modbus address is automatically set equal
to the Modbus address of the 2410 Tank Hub itself. See “Tank Database
Setup” on page 5-42 for further information.
The Modbus address configuration is summarized in Table 5-3 below:

The 2410 Level addresses in the 2160 FCU Slave Database must be equal to
the Level Modbus addresses in the 2410 Tank Database.
In this example the Level Modbus addresses of the three tanks are entered in
positions 1A, 2A, and 3A in the 2160 FCU Slave Database and in tank
positions 1, 2, and 3 in the 2410 Tank Database as illustrated in Figure 5-7:
