2.1 Introduction
In a typical Rosemount
™
Tank Gauging system, a Rosemount 2460 System Hub collects measurement
data and status information from various field devices. A standard installation includes a
Rosemount 2460 connected to a number of Rosemount 2410 Tank Hubs which collect measurement
data and status information from the field devices.
A Rosemount 2460 buffers measurement data and status information from one or more tanks, and
sends the information to a TankMaster PC, or other host system, whenever the
Rosemount 2460
receives a
request for data.
