LCD TRANSDUCER
BLOCK
The LCD meter connects directly to the 3051S electronics FOUNDATION
fieldbus output board. The meter indicates output and abbreviated diagnostic
messages.
The meter features a four-line display and a 0-100% scaled bar graph. The
first line of five characters displays the output description, the second line of
seven digits displays the actual value, the third line of six characters displays
engineering units and the fourth line displays “Error” when the transmitter is in
alarm. The LCD meter can also display diagnostic messages.
Each parameter configured for display will appear on the LCD for a brief
period before the next parameter is displayed. If the status of the parameter
goes bad, the LCD will also cycle diagnostics following the displayed variable:

Configuration
Shipped from the factory, Parameter #1 is configured to display the Primary
Variable (pressure) from the LCD Transducer Block. Parameters 2 – 4 are not
configured. To change the configuration of Parameter #1 or to configure
additional parameters 2 – 4, use the configuration parameters below.
The LCD Transducer Block can be configured to sequence four different
process variables as long as the parameters are sourced from a function
block that is scheduled to execute within the 3051S pressure transmitter. If a
function block is scheduled in the 3051S that links a process variable from
another device on the segment, that process variable can be displayed on the
LCD.
