2.3System overview
The Rosemount Tank Gauging system is a state-of-the art inventory and custody transfer
radar tank level gauging system. It is developed for a wide range of applications at
refineries, tank farms and fuel depots, and fulfills the highest requirements on
performance and safety.
The field devices on the tank communicate over the intrinsically safe Tankbus. The
Tankbus is based on a standardized fieldbus, the FISCO
integration of any device supporting that protocol. By utilizing a bus powered 2-wire
intrinsically safe fieldbus the power consumption is minimized. The standardized fieldbus
also enables integration of other vendors’ equipment on the tank.
The Rosemount Tank Gauging product portfolio includes a wide range of components to
build small or large customized tank gauging systems. The system includes various
devices, such as radar level gauges, temperature transmitters, and pressure transmitters
for complete inventory control. Such systems are easily expanded thanks to the modular
design.
The Rosemount Tank Gauging system is a versatile system that is compatible with and can
emulate all major tank gauging systems. Moreover, the well-proven emulation capability
enables step-by-step modernization of a tank farm, from level gauges to control room
solutions.
It is possible to replace old mechanical or servo gauges with modern Rosemount Tank
Gauging devices, without replacing the control system or field cabling. It is further
possible to replace old HMI/SCADA-systems and field communication devices without
replacing the old gauges.
There is a distributed intelligence in the various system units which continuously collect
and process measurement data and status information. When a request for information is
received an immediate response is sent with updated information.
The flexible Rosemount Tank Gauging system supports several combinations to achieve
redundancy, from control room to the different field devices. Redundant network
configuration can be achieved at all levels by doubling each unit and using multiple control
room work stations.

Overview
2.3.1TankMaster HMI software
Rosemount TankMaster is a powerful Windows-based Human Machine Interface (HMI) for
complete tank inventory management. It provides configuration, service, set-up,
inventory, and custody transfer functions for Rosemount Tank Gauging systems and other
supported instruments.
Rosemount TankMaster is designed to be used in the Microsoft® Windows environment
providing easy access to measurement data from your Local Area Network (LAN).
The Rosemount TankMaster WinOpi program lets the operator monitor measured tank
data. It includes alarm handling, batch reports, automatic report handling, historical data
sampling as well as inventory calculations such as Volume, Observed Density and other
parameters. A plant host computer can be connected for further processing of data.
The Rosemount TankMaster WinSetup program is a graphical user interface for
installation, configuration and service of devices in the Rosemount Tank Gauging system.
2.3.2
Rosemount 2460 System Hub
The Rosemount 2460 System Hub is a data concentrator that continuously polls and
stores data from field devices such as radar level gauges and temperature transmitters in a
buffer memory. Whenever a request for data is received, the system hub can immediately
send data from the updated buffer memory for a group of tanks.
Measured and calculated data from one or more tanks is communicated via the
Rosemount 2410 Tank Hub to the system hub buffer memory. Whenever a request is
received, the system hub can immediately send data from a group of tanks to a
TankMaster PC, or a host.
The Rosemount 2460 can be used to connect devices from other vendors as well, such as
Honeywell® Enraf and Whessoe.
The Rosemount 2460 has eight slots for communication interface boards. These boards
can be individually configured for communication with hosts or field devices. They can be
ordered either for TRL2, RS485, Enraf BPM or Whessoe 0-20 mA/RS485 communication.
Two slots can also be configured for RS232 communication.
One of the system hub’s three Ethernet ports is used for Modbus TCP connection to host
systems. By simply connecting the system hub to the existing LAN network,
communication over Ethernet is established.
The system hub can provide redundancy for critical operations, by using two identical
devices. The primary system hub is active and the other one is in passive mode. If the
primary unit stops working properly, the secondary unit is activated and a failure message
is sent to TankMaster (or a DCS system).
2.3.3
Rosemount 2230 Graphical Field Display19
Rosemount 2410 Tank Hub
The Rosemount 2410 Tank Hub acts as a power supply to the connected field devices in
the hazardous area using the intrinsically safe Tankbus.
The tank hub collects measurement data and status information from field devices on a
tank. It has two external buses for communication with various host systems.
Overview
March 202100809-0100-2230
There are two versions of the Rosemount 2410 Tank Hub; one for single tank operation
and one for multiple tanks operation. The multiple tanks version of the Rosemount 2410
supports up to 10 tanks and 16 devices. With the Rosemount 5300 the Rosemount 2410
supports up to 5 tanks.
The Rosemount 2410 is equipped with two relays which support configuration of up to 10
“virtual” relay functions allowing you to specify several source signals for each relay.
The Rosemount 2410 supports Intrinsically Safe (IS) and Non-Intrinsically Safe (Non-IS)
analog 4-20 mA inputs/outputs. By connecting an Emerson Wireless 775 THUM Adapter
to the IS HART 4-20 mA output, the tank hub is capable of wireless communication with an
Emerson Wireless Gateway in a WirelessHART® network.

Note
When grounding the display via threaded conduit, make sure the connection provides
sufficient low impedance.
Grounding - FOUNDATION™ Fieldbus
Signal wiring of the fieldbus segment can not be grounded. Grounding out one of the
signal wires may shut down the entire fieldbus segment.
Shield wire connection
To protect the fieldbus segment from noise, grounding techniques for shield wire usually
require a single grounding point for shield wire to avoid creating a ground loop. The
ground point is typically at the power supply (Rosemount 2410 Tank Hub).
The Rosemount Tank Gauging devices are designed for “daisy-chain” connection of shield
wiring in order to enable a continuous shield throughout the Tankbus network. The shield
wire terminal in the Rosemount 2230 is not connected to ground. It merely provides
electrical continuity to daisy-chained Tankbus cables.
3.4.3
Cable selection
Use shielded twisted pair wiring for the Rosemount 2230 in order to comply with FISCO
requirements and EMC regulations. The cables must be approved for use in hazardous
areas, where applicable. In the U.S. explosion-proof conduits may be used in the vicinity of
the vessel.
We recommend cable size 0.75 mm2 (18 AWG) in order to facilitate wiring. Cables within
the range 22 AWG to 16 AWG (0.5 to 1.5 mm2) can be used in order to minimize the
voltage drop to the Rosemount 2230 display.
Tankbus cabling must be approved for use in minimum 85°C to match requirements for all
devices in a Rosemount Tank Gauging system.
The FISCO specification requires that cables for the Tankbus comply with the following
parameters:
