LCD Transducer block

The LCD Transducer block supports Basic Display. The block is used to configure the
basic display connected to the ST 700 transmitter. The block stores the LCD
configurations, and sends these values to the Display while the transmitter is powered up or
restarted.
ATTENTION
The initial configuration of LCD transmitter is configured to show four screens
with Primary Value, Secondary Value, Tertiary Value and Electronics
temperature.
The Display shows the available set of process variables, and all function block
inputs/outputs. In addition, the block reports the current device status and errors. If a
function block parameter which is not currently a part of the control strategy is selected, an
error appears in the display.

Execution

Basic Display
The PV value is user-configurable. This field has 7 characters. The maximum allowable
numeric value is 9999999 or -999999. If fractional decimals are configured, the fractional
positions are dropped, as desired. If the PV value exceeds the above limits, it is divided by
1000 and "K" is appended to the result, allowing a maximum value with multiplier of
999999K or -99999K. This field is user-configurable. This field has 8 characters.
