PROTOCOL SETUP
The TRL2 Modbus Master protocol is available as default protocol when
Rosemount TankMaster is installed on a TankMaster work station. Other
protocols, such as the Modbus Slave protocol for communication with host
systems, can be obtained as option. Contact Emerson Process Management /
Rosemount Tank Gauging for more information.
A protocol offers up to eight channels. For each channel you can specify
which PC communication port (USB/COM) to connect to, as well as standard
communication parameters such as Baud Rate and number of Stop Bits.

For each protocol you can configure the following:
• Communication parameters: COM Port, Baud rate, number of stop bits,
