Displaying Device Setup
Options
The Device Setup on the HART Online menu accesses every configurable parameter
for the connected device. Some devices may not display a Device Setup menu. Check
your device documentation for more information. Double-tap Device setup to view the
process variables, diagnostics and service, basic setup, detailed setup, and review
menus.
Process Variables
The Process Variables menu lists all process variables and their values. Process
variables are continuously updated when this window is displayed.
Diagnostics and Service
The Diagnostics and Service menu offers device and loop tests as well as calibration
options. The diagnostics and service operations that are available vary widely from
device to device and are defined in the device description.
The Test device menu lists the status as well as self and master test of the device. Test
device initiates a diagnostic routine at the device and can report an electronics failure,
as well as other failures that can affect performance.
Loop test is used to set the output of the device at a specified analog value, and may
be used to test the integrity of the loop and the operation of indicators, recorders, or
similar devices in the loop.
Calibration is used to perform such operations as performing a sensor trim, D/A trim,
and scaled D/A trim.
Basic setup
The Basic setup menu provides quick access to a number of configurable parameters
including tag, unit, range values, and damping.
The options available in the Basic setup menu are the most fundamental tasks that
can be performed with a device. These tasks are a subset of the options available
under the Detailed setup menu.
The Tag identifies a specific device. Changing the unit option affects the engineering
units that are displayed. Changing range values modifies the analog output scaling.
Changing damping affects the response time of the transmitter and is often used to
smooth the output when there are rapid input variations.
A modified parameter is highlighted yellow and an asterisk appears to indicate the
change has not been sent to the device. Tap Send to update the device.
