C.1 Alert message mapping
This outlines the most important alerts in the HART
®
command 48 Additional Status Field
for the Rosemount
™
648 Wireless Temperature Transmitter. The information in this section
can be used by DeltaV
™
for alert monitoring, and in the Rosemount 1420 Smart Wireless
Gateway for Additional Status mapping in Modbus
®
, OPC, etc.
A complete list of Additional Status bits is available in the Rosemount 1420 Reference
Manual .
Table C-1 to Table C-3 shows a list of the most important alert messages that may display in
the AMS
™
Wireless Configurator and Field Communicator together with the location of the
Alert in the HART command 48 Additional Status field. For recommended actions refer to
Table 6-1 . on page 53 .
To view Active Alerts, from the Home screen, go to Service Tools>Active Alerts .
