LO_LO_LIM: Value of the lower limit of alarms.
HI_HI_ALM: State of the upper limit of alarms.
HI_ALM: State of the upper limit of warnings.
LO_ALM: State of the lower limit of warnings.
LO_LO_ALM: State of the lower limit of alarms.
SIMULATE: For commissioning and test purposes, the
input value of the Transducer Block in the AI Block can be
modified.
OUT_UNIT_TEXT: Allows the user to write text if a spe-
cific unit of the OUT parameter is not in the code list.
The TRANSDUCER and AI Block’s actual mode in the
MODE_BLK parameter must be set to AUTO to pass the
PV Value through the AI to the network.
Transducer scaling, called PV_SCALE, is applied to the
PV from the CHANNEL to produce the FIELD_VAL in
percent. Units of PV_SCALE are the same as the units of
the TRANSDUCER BLOCK process variable comfigured
by channel.
Damping Filter is a feature of the AI Block. PV_FTIME
parameter is the time constant of a single exponential filter
for the PV, in seconds. This parameter can be used to
dampen out fluctuation in level due to excessive turbulence.
The AI Block has multiple ALARM functions that monitor
the OUT parameter for out of bound conditions.
4.5.2 Local Display of Analog Input Block Output Values
The Model 705 3x PROFIBUS PA^™ [Device Revision 2]
transmitter incorporates a feature that allows the device’s
Analog Input [AI] Block Out values to be displayed on the
local LCD.
NOTE: There are many reasons that AI Block Out values can deviate
from the measurement value originating in the Transducer
block, and because the keypad and local display will only pro-
vide access to Transducer block parameters, there is no way to
explore or change the other fieldbus configuration items affect-
ing the AI Block output using the keypad and LCD.
These screens should only be considered as measured value
indicators for configured transmitters.
• The screens are not used for commissioning or diagnostic /
troubleshooting purposes.
• Prior to configuration of AI Blocks, the value displayed will
not reflect the transducer measurement. (Pre-configuration
values will typically be 0).
