Quick Start Guide

Step 3: Verify the tag

The 848T has a removable commissioning tag that

contains both the Device ID (the unique code that

identifies a particular device in the absence of a device

tag) and a space to record the device tag (the

operational identification for the device as defined by

the Piping and Instrumentation Diagram [P&ID]).

When commissioning more than one device on a

Foundation fieldbus segment, it can be difficult to

identify which device is at a particular location. The

removable tag aids in this process by linking the Device

ID to physical location. The installer should note the

physical location of the transmitter on both the upper

and lower location of the commissioning tag. The

bottom portion should be torn off for each device on the

segment and used for commissioning the segment in

the control system.

Step 4: Verify the transmitter configuration

Each FOUNDATION fieldbus host or configuration tool has a different way of

displaying and performing configurations. Some use Device Descriptions (DD) or

DD wizards for configuration and to display data consistently across platforms.

There is no requirement that a host or configuration tool support these features.

The following is the minimum configuration requirement for a temperature

measurement. This guide is designed for systems not using DD wizards. For a

complete list of parameters and configuration information refer to the

Rosemount 848T Reference Manual (document number 00809-0100-4697).

Sensor transducer block

This block contains temperature measurement data for all eight sensor inputs. It

also includes information about sensor type, engineering units, damping, and

diagnostics. At a minimum, verify the parameters in Ta bl e 1 for each sensor in the

transducer block.
