Configuration
4.7 LCD display transducer block
The LCD display connects directly to the transmitter electronics FOUNDATION Fieldbus output board. The
meter indicates output and abbreviated diagnostic messages.
The first line of five characters displays the sensor being measured.
If the measurement is in error, “Error” appears on the first line. The second line indicates if the device or
the sensor is causing the error.
Each parameter configured for display will appear on the LCD display for a brief period before the next
parameter is displayed. If the status of the parameter goes bad, the LCD display will also cycle diagnostics
following the displayed variable:
4.7.1 Custom meter configuration
Parameter #1 (Sensor 1) is factory configured to display the primary variable (temperature) from the LCD
display transducer block. When shipping with dual sensors, sensor 2 will be configured not to display. To
change the configuration of parameter #1, #2, or to configure additional parameters use the
configuration parameters below. The LCD display transducer block can be configured to sequence four
different process variables as long as the parameters are sourced from a function block scheduled to
execute within the transmitter. If a function block is scheduled in the transmitter that links a process
variable from another device on the segment, that process variable can be displayed on the LCD display.
DISPLAY_PARAM_SEL
The DISPLAY_PARAM_SEL specifies how many process variables will be displayed, where up to four
display parameters can be selected.
BLK_TAG_#
(1)
Enter the block tag of the function block containing the parameter to be displayed. The default function
block tags from the factory are:
TRANSDUCER
AI 1400, 1500, 1600, 1700
PID 1800 and 1900
ISEL 2000
CHAR 2100
ARTH 2200
Output Splitter OSPL 2300
Terminal (Body) Temperature Beyond
Operating Limits
PRT readings have gone below 2% of lower range or above 6% of upper
range of PRT. (These ranges are calculated and are not the actual range
of the PRT which is a PT100 A385).
Sensor Degraded
For RTDs, this is excessive EMF detected.
For Thermocouples, the loop resistance has drifted beyond the
user-configured threshold limit.
Calibration Error
The user trim has failed due to excessive correction or sensor failure
during the trim method.
1. # represents the specified parameter number.
