C.1 Mapping of alert messages in the HART command
48 additional status
This outlines the most important alerts in the HART command 48 Additional Status Field for 248
Wireless 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 Smart Wireless
Gateway.
Tab le C -1 to Tab le C -3 shows a list of the most important alert messages that may be displayed
in the AMS Wireless Configurator and Field Communication together with the location of the
Alert in the HART command 48 Additional Status field. For recommendation actions refer to
Tab le 6 -1 . on page 35.
To view Active Alerts, from the Home screen, go to Service Tools > Active Alerts.
