4.4.2 Factory Parameters
The factory-adjustable calibrated parameters are found in the
factory calibration menu.
The following parameters are read-only and are available for
troubleshooting and diagnostics.
LVDT %:
current sensor output
ADJUSTED_SENSOR_LO:
low sensor calibration point
which may be adjusted for process SG and/or temperature.
ADJUSTED_SENSOR_HI:
high sensor calibration point
which may be adjusted for process SG and/or temperature.
CONVERSION_FACTOR:
the slope of the factory-set
calibration line, based on the selected calibration.
SCALE_OFFSET:
the intercept of the calibration line.
4.4.3 Firmware Version
The last parameter in the TRANSDUCER block gives the
firmware version of the transmitter.
FIRMWARE_VERSION:
displays the version of the
firmware.
NOTE: The user should compare the DD file and revision number of the
device with the HOST system to ensure they are at the same
revision level.
4.5
Analog Input Block
The ANALOG INPUT (AI) block takes the manufacturer’s
input data and makes it available to other function blocks at
its output.
Since only one measured value is available depending on
the configuration of the unit, only one channel selection is
defined in the AI Function Block. The channel will be
identified as “Primary Value,” and will also be defined as
the default Channel.
4.5.1 ai Block Parameters
PV:
Either the primary analog value for use in executing the
function, or a process value associated with it.
OUT:
The primary analog value calculated as a result of
executing the function block.
SIMULATE:
Allows the transducer analog input or output
to the block to be manually supplied when simulate is
enabled. When simulate is disabled, the simulate value and
status track the actual value and status.
