Section 5. Installing a Raptor Level Gauging System
To configure the FCU Slave Database:
a. Select a free database position (1A, 2A ...) for the level gauge
device to be configured.
b. Choose Slave type=2410 Level.
The corresponding Slave Database position (1B, 2B ...) for
temperature transmitters and other auxiliary tank devices is
automatically assigned to Slave Type=2410 Temp.
c. Enter Modbus addresses for level gauges and auxiliary tank
devices (ATD). Ensure that the same database positions, .i.e.
1A/1B, 2A/2B and so on, are used for level gauges and ATDs on the
same tank.
d. Select the communication fieldbus (FB1, FB2, FB3, FB4) that the
Rosemount 2410 is connected to. Normally there are four fieldbus
ports available on the 2160 Field Communication Unit. The RS485
bus is the standard fieldbus interface for a Rosemount 2410 Tank
Hub connected to a Rosemount 2160 FCU.
e. If temperature elements are installed in the tank, type the number of
elements in the Temp column.
The 2160 Slave Database and the 2410 Tank Database
In a typical Raptor system a Rosemount 2160 FCU collects measurement
data from a number of tanks via one or more Rosemount 2410 Tank Hubs.
The Modbus addresses of the field devices on the tank need to be stored in
the 2160 FCU slave database as well as in the Rosemount 2410 tank
database for proper communication with the control room PC.
Level Gauge Modbus Address - 2410 Level
The 2410 Level address field in the 2160 FCU slave database is used for
level gauges such as the Rosemont 5900S. This address also needs to be
stored in the 2410 tank database as the Level Modbus address. This is
normally done as part of the installation procedure of the Rosemount 2410 as
described in chapter “Installing a Rosemount 2410 Tank Hub” on page 5-38.
ATD Device Modbus Address - 2410 Temp
The 2410 Temp Modbus address in the 2160 FCU slave database is used for
all devices on a tank except level gauges. This address also needs to be
stored in the ATD Modbus address field of the 2410 tank database. This is
normally done as part of the installation procedure of the Rosemount 2410 as
described in chapter “Installing a Rosemount 2410 Tank Hub” on page 5-38.
The first tank in the 2410 tank database uses the Modbus address of the 2410
Tank Hub itself as the ATD Modbus address. Tank number two, three etc. use
separate ATD Modbus addresses. The 2410 Modbus address is automatically
set as the ATD Modbus address for tank position 1 in the 2410 Tank Database
as illustrated in Figure 5-5 on page 5-34.
It is recommended that address range 1 to 99 is used for level gauges and
101 to 199 for ATD devices.
See “Examples of 2160 FCU Slave Database Configuration” on
page 5-32 for further information on how to configure the Slave Database of
the 2160 Field Communication Unit (FCU) and the Tank Database of the
Rosemount 2410 Tank Hub.
