Floating point format code
Common Modbus host configuration
RTU data type
The RTU data type specifies which configuration to use in the RTU in order for the RTU to
correctly interpret a floating point number transmitted from the Rosemount 5300 Level
Transmitter with Modbus.
Input register base number
Data registers in the Rosemount 5300 Level Transmitter with Modbus are numbered
exactly as they are transmitted in the Modbus communication. Some RTUs use different
naming conventions and to configure the RTU to poll the correct registers from the
Rosemount 5300 Level Transmitter Modbus, an Input Register Base Number is stated for
each RTU respectively. For example, if the input register base number is 1 for the RTU, the
Rosemount 5300 Level Transmitter Modbus input register 1302 has to be entered in the
RTU address as input register 1303.
