Rosemount 3051S Advanced HART
Diagnostics with a Field Communicator
INTRODUCTION
The purpose of this document is to explain the basics
of configuring and using the Rosemount 3051S HART
Advanced Diagnostics Pressure Transmitter with a
375 or 475 Field Communicator. The instructions are
written around the Advanced Diagnostics DA2 option
(3051S HDT Rev. 3). For more detailed information
on 3051S Advanced Diagnostics, refer to the product
user's manual 00809-0100-4801.
CONFIGURATION OF ADVANCED
DIAGNOSTICS
The setup of Advanced Diagnostics is done within the
Guided Setup menu of the Field Communicator.
Enabling and configuring the Statistical Process
Monitoring (SPM) diagnostic and the Power Advisory
diagnostic will be explained here.
Configuring the SPM Diagnostic
To start the SPM Guided Setup, from the overview
screen, use the menu keys:
Configure (2) > Guided Setup (1) > Diagnostics Setup
(2) > Statistical Process Monitoring (1)

Rosemount 3051S
You will be given a warning message that the control
loop should be removed from automatic control. Click
OK on the message. Note that configuring the
Statistical Process Monitoring diagnostic will not affect
the pressure measurement or analog output of the
transmitter.
Figure 2. Warning Message
Next, you will see the following message:
Turn SPM On or Off? Statistical Process Monitoring
monitors process conditions to generate HART alerts
or analog alarms (On).
Select the option "On" to activate the SPM diagnostic.
