Rosemount 848T
TAGGING Commissioning Tag
The 848T has been supplied with 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 fieldbus segment, it can be
difficult to identify which device is at a particular location. The removable tag,
provided with the transmitter, can aid in this process by linking the Device ID
to its 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.
