Rosemount 2410
Section 3. Installation
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 terminator in one of the Raptor field devices, or an
external terminator plugged into one of the devices, or a segment coupler with
integrated bus terminator.

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” on page 3-6.
