Measurement data and status information from one or more tanks is distributed via the
Primary Bus to a Rosemount 2460 System Hub. Data is buffered by the system hub and
distributed to a TankMaster PC, or a host system, whenever the 2460 receives a request
for data. In case no system hub is included in the system, the Rosemount 2410 Tank Hub
can communicate directly with a host computer.
The Rosemount 2410 has two external buses for communication with host systems. The
Primary Bus is typically used with the TRL2 Modbus
®
or RS-485 Modbus protocol for
communication with a 2460 System Hub. If there is no Rosemount 2460 included, the
Primary bus can communicate directly, or via a modem, with the TankMaster PC.
The Secondary Bus supports various protocols such as TRL2 Modbus, Enraf
®
, and Varec
which allows you to connect to other systems as well.
The Rosemount 2410 is equipped with two solid state relays that allows controlling
external devices such as valves and pumps.
An integral display (optional) presents measurement data and device status such as
warnings and error messages. At start-up, communication settings and optional hardware
configuration is presented as well as whether it is a Single tank or Multiple tank version of
the Rosemount 2410 Tank Hub.
Using the input from a Rosemount 5900S Radar Level Gauge and one or two pressure
sensors, the Rosemount 2410 can be configured for online presentation of Observed
Density to a host computer. The tank hub also calculates Average Temperature and
strapping table based Volume.
The Rosemount 2410 can be equipped with two relays which can be controlled by level,
temperature, and water level. The output can be connected to an external system for
alarm indication or process control. The relays are user configurable for normally open or
closed operation.
The Rosemount 2410 can be configured with up to ten “virtual” relay functions. This
allows you to specify several different source variables to trigger a relay.
The Rosemount 2410 supports the Emerson’s Wireless solution, which is based on
WirelessHART
®
the emerging industry standard for wireless field networks. By connecting
to an Emerson Wireless 775 THUM
™
Adapter, the Rosemount 2410 can be integrated in a
wireless network to provide measurement data at greatly reduced field wiring costs. The
tank hub supports communication with Emerson Wireless Gateways 1410 and 1420.
2.2 Communication
The Rosemount Tank Gauging system supports various communication interfaces
between a Rosemount 2410 and a TankMaster PC or other host computers as illustrated in
Figure 2-2 to Figure 2-4.
Both the Primary bus and the Secondary bus can be used for either TRL2 Modbus
(standard) or RS485 Modbus communication

.
On the Secondary bus you may use other communication protocols as well, such as Enraf,
Varec etc.
