6.0 ON-LINE CONFIGURATION AND OPERATION
A transmitter is shipped with default data in its memory. Some of this data controls communication and
transmitter operation and cannot be altered. Other data is used by the transmitter to respond to changes in
pressure with a change in output current or HART digital output and is alterable by the user. This data
includes configuration parameters that set up the transmitter for use in a specific process environment.
On-line operation includes local configuration using the magnetic pushbuttons on the transmitter
enclosure and remote configuration and monitoring involving communication between the HART
Communicator (host device) and transmitter.
There are four major subsections. Section 6.1 introduces the local digital display and the local magnetic
pushbuttons. Section 6.2 provides details about configuring and using the transmitter locally; the optional
display must be installed. Section 6.3 describes use of a transmitter that does not have a display. Finally,
Section 6.4 provides the steps to configure and monitor a transmitter from a HART Communicator.
6.1 LOCAL OPERATION AND DISPLAY
Local configuration and operation make use of built-in magnetic
pushbuttons and an optional digital display. As shown in the
adjacent figure, the display (1) is behind the enclosure cap. The
magnetic pushbuttons are under the hinged cover (2).
There are three magnetic pushbuttons or keys:
M = Mode Select
( = Increase
' = Decrease
Use the display and the magnetic pushbuttons as described in
this section.
6.1.1 Digital Display
The local display can show the measured value and engineering unit, sign, status, mode, and output
current; see Figure 6-1. The root sign appears when a square root characteristic is used for differential
pressure or flow. HART communications is indicated by flashing of the communication indicator.
1 Numeric display
2 Unit/bargraph display
3 Root display (flow)
4 Mode/pushbutton disable
5 Status -lower current limit reached
6 Sign for measured value
7 Status - upper current limit reached
8 HART communication indicator
