Note that the total length of the Tankbus (fieldbus segment) must be within the FISCO
specifications and the spurs must not exceed 60 meter, see Cable selection for the
Tankbus.
Several tanks daisy-chained to a Rosemount 2410
Figure 3-10 illustrates an example with a number of field devices daisy-chained to a
Rosemount 2410 Tank Hub (requires multiple tanks option).
If a field device is connected to the end of the Tankbus (fieldbus segment), the built-in
terminator can be used. Another option is to use a separate bus terminator.

The Rosemount 2410 Tank Hub has a built-in terminator and intrinsically safe power
supply with integrated power conditioner.
Note that the total length of the Tankbus (fieldbus segment) must be within the FISCO
specifications, see Cable selection for the Tankbus.
Three tanks connected to the Tankbus via segment couplers
Figure 3-11 illustrates an example with three tanks connected to a Rosemount 2410 Tank
Hub (requires multiple tanks option). For each tank the field devices are connected to the
Tankbus via a segment coupler.
The fieldbus segment needs to be terminated at both ends. A terminator is enabled in the
Rosemount 2410 Tank Hub. At the end of the fieldbus segment you may use the built-in
