1.0 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 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.
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
Sakura protocol overview
The tank hub supports two versions of the Sakura protocol: Sakura MDP and Sakura V1, each supporting
all 10 tank positions. The tank hub automatically detects which protocol to use, based on the received
requests from the Sakura host.
The Sakura MDP protocol is sometimes also called “old Sakura protocol” or Sakura binary. The Sakura
MDP protocol includes one request type.
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
The Sakura interface can be connected to the Rosemount 2410 secondary field bus.
The primary bus can be used for regular TRL2 or RS485 Modbus communication. Configuration is
performed with a TRL2 modem, like the Rosemount 2180 Field Bus Modem (FBM), or a RS485 converter
connected to the primary field bus.

3.0 Configuration
The Rosemount 2410 Tank Hub is configured by using the TankMaster WinSetup configuration
program
well as advanced configuration and service functions.
Configuration of the Rosemount 2410 Sakura emulation function can be performed with the WinSetup
program using the FBM or a RS485 converter, depending on the tank hub configuration.
