Rosemount 5300/5400 Series
INTRODUCTION
The Rosemount 5300 Series and Rosemount 5400 Series transmitters are
Modbus compatible measurement devices that support communication with a
Remote Terminal Unit (RTU) using a subset of read, write, and diagnostic
commands used by most Modbus compatible host controllers. The
transmitters also support communication through Levelmaster and Modbus
ASCII protocols.

The HART

to Modbus Converter (HMC) module is located inside the
Rosemount 5300 and Rosemount 5400 transmitter enclosure and provides
power to and communicates with the transmitter through a HART interface.

Figure 1-1. System Overview
During normal operation, the HMC “mirrors” the contents of process variables
from the 5300/5400 transmitter to the Modbus registers. To configure the
5300/5400 transmitter, it is possible to connect a configuration tool to the
HMC. See “Transmitter Configuration” on page 1-13 for more information.

WORKFLOW
Overview of workflow for commissioning a Rosemount 5300 or a Rosemount
5400 transmitter with Modbus protocol:
5400 transmitter with Modbus protocol:
1. Mount the transmitter on the tank.
2. Connect the power and communication wires.
3. Establish HART communication with the transmitter through Rosemount
Radar Master, or a Field Communicator. This is done by:
•
Connecting to the HART terminals, or
•
Connecting to the MA/MB terminals (tunneling mode)
4. Configure the transmitter.
5. Configure the Modbus communication.
6. Configure Modbus host.
7. Verify output values as reported by the transmitter.
