J.7
Transmitter configuration
Configuration data such as tank height, Upper Null Zone, dielectric constants, and other
basic parameters are configured in the same way as for a standard Rosemount 5300
Transmitter. For more information, see
.
Make sure the measurement unit of the Primary Variable (PV) matches the configuration of
the Modbus Host since the transmitter output value does not include any information on
associated measurement units.
For further information on basic configuration, see
Note
The Rosemount 5300 Series Transmitter with Modbus protocol is configured to HART
address 1 at factory. This reduces power consumption by locking the analog output at 4
mA.
J.8
Modbus communication protocol
configuration
The Rosemount 5300 Series Level Transmitter can communicate with RTUs using Modbus
RTU (often referred to as just “Modbus”), Modbus ASCII, and Levelmaster (also known as
“ROS,” “Siemens,” or “Tank” protocol).
Table J-3. List of RTU Supported Protocols
Modbus ASCII is not commonly used, since it doubles the amount of bytes for the same
message as the Modbus RTU.
If you do not have any of these RTUs, check your RTU manual to see which protocols it
supports.

Levelmaster protocol should be used when using the Emerson Process Management Digital Level Sensor (DLS) User
Program or Application Module together with the device. Use Modbus RTU in other cases.
