1 Introduction
The purpose of this document is to provide guidelines on how to change from other
manufacturer’s devices to Rosemount equipment by exchanging gauges. When a gauge is
replaced with a Rosemount gauge, it is necessary to configure the Rosemount 2410 Tank
Hub for emulation.
The Rosemount field devices, for example Rosemount 5900 Radar Level Gauge and
Rosemount 2240S Temperature Transmitter, are connected to the tank hub using the
intrinsically safe Tankbus as usual. Emulation is done in the tank hub only. Each tank hub
can emulate up to 10 tanks (10 separate gauges)(1).

1.1 Emulation capabilities
Emulation enables the replacement of old devices with Rosemount devices in another
vendor’s existing tank gauging system. The Rosemount device will perform just like the
replaced gauge, using the other vendor’s protocol to communicate.
By using the other vendor’s field and control room communication protocol with modern
Rosemount tank gauging devices, the legacy system can be modernized step-by-step. The
legacy system can be upgraded while tanks are in operation and existing wiring can be
re-used.
The tank hub can emulate replaced devices, acting as either slave or master. The tank hub
slave emulation is described in this document.
Tank hub acting as slave
When an old gauge from another vendor is replaced with a tank hub connected to a
Rosemount field device, the tank hub will act as a slave answering requests and sending
data upwards towards the host.
A stepwise “bottom-up” upgrade is done by replacing legacy gauges to begin with, and
changing the complete control system at a later occasion.

1.2 Sakura system characteristics
1.2.1 Sakura protocol overview
The tank hub supports two versions of the Sakura protocol: Sakura MDP and Sakura
V1, each supporting up to 10 tank positions(2). The tank hub automatically detects which
protocol to use, based on the received requests from the Sakura host.
Sakura MDP protocol
The Sakura MDP protocol is sometimes also called “old Sakura protocol” or Sakura binary.
The Sakura MDP protocol includes one request type.
Sakura V1 protocol
The Sakura V1 protocol is sometimes called “new Sakura protocol” or Sakura ASCII. The
Sakura V1 protocol includes several request types. The tank hub identifies the request type,
and replies with the corresponding response type.

1.3 Rosemount 2410 Tank Hub communication
The tank hub has slots for two independent communication boards, primary and
secondary field bus, for TRL2 Modbus®, RS485 Modbus, emulation, or wireless
communication.
Support for Sakura emulation is selected in the model code, refer to Rosemount 2410
Product Data Sheet for more information. There are two alternatives available for Sakura
emulation:
•Example 1: Sakura MDP/V1 on secondary bus
Sakura is available on the secondary bus, where the primary bus can be used for
regular TRL2 or RS485 communication.
•Example 2: Wireless communication in combination with Sakura emulation
Sakura is available on the primary bus, where the secondary bus is used for
WirelessHART® for normal communication.
Example 1: Sakura MDP/V1 on secondary bus
The Sakura MDP/V1 interface is connected to the Rosemount 2410 secondary field bus.
Configuration is usually performed with a FBM connected to the primary bus. The primary
bus can be used for regular TRL2 or RS485 Modbus communication.

Example 2: Wireless communication in combination with Sakura emulation
The tank hub supports Emerson’s wireless technology, which is based on WirelessHART,
the emerging industry standard for wireless field networks. The Emerson Wireless THUM™
Adapter acts as a wireless data link between the tank hub and an Emerson Wireless
Gateway.
The tank hub can simultaneously combine wireless and Sakura communication. The
primary field bus communicates via Sakura MDP/V1, and the secondary field bus via
WirelessHART. With this tank hub communication configuration, control room redundancy
is achieved.

3 Configuration
The Rosemount 2410 Tank Hub is configured by using the TankMaster WinSetup
configuration program(3). WinSetup is a user-friendly software package that includes basic
configuration options as well as advanced configuration and service functions.
Configuration of the Rosemount 2410 emulation function can be performed with the
WinSetup program using the FBM or a RS485 converter, depending on the tank hub
configuration. A tank hub where the secondary field bus communicates via WirelessHART®,
can be configured by wireless communication with an Emerson Wireless Gateway.
