Communication

The Rosemount Tank Gauging system supports various communication interfaces between a
Rosemount 2410 and a TankMaster PC or other host computers as illustrated in
Both the Primary bus and the Secondary bus can be used for either TRL2 Modbus (standard) or RS485
Modbus communication
On the Secondary bus you may use other communication protocols as well, such as Enraf, Varec etc.
