The Rosemount 5300 Series and Rosemount 5400 Series can be configured using the Rosemount Radar Master (RRM) PC software or a Field Communicator. Configuration is done by sending HART commands through the HART to Modbus Converter (HMC) to the 5300/5400 transmitter electronics. To establish HART communication, connect to the MA/MB terminals, or to the HART terminals. Both alternatives are described below.
The 5300/5400 level transmitter can be configured with RRM using the MA, MB terminals.
An
The transmitter will try to establish communication using different protocols during 20 second timeslots from time of startup.
