B.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 Wireless
Gateway for Additional Status mapping in Modbus
®
, OPC UA
®
, etc.
A complete list of additional status bits is available in the Rosemount 1420 Reference
Manual .
