Emerson Process Management's transmitters include the ability to communicate via the Modbus communications protocol
Emerson Process Management's Rosemount 5300 Series Guided Wave Radar (GWR) and 5400 Series non-contacting level transmitters include the ability to communicate via the Modbus communications protocol. The addition of Modbus enables the transmitter to emulate LevelMaster — sometimes known as ROS or tank — protocol.
The transmitters feature an integral HART to Modbus converter (HMC). This enables up to four external HART transmitters of any type to be connected, and their signals communicated via the Modbus network.
The devices can be configured using Emerson’s Radar Master software, point-to-point via HART communications or remotely by using HART Tunnelling over the Modbus network.
