Advanced Features
The AI function block provided with Fisher
™
-Rosemount
™
fieldbus devices provides added
capability through the addition of the following parameters:
ALARM_TYPE
– Allows one or more of the process alarm conditions detected by the AI
function block to be used in setting its OUT_D parameter.
OUT_D
– Discrete output of the AI function block based on the detection of process alarm
condition(s). This parameter may be linked to other function blocks that require a discrete
input based on the detected alarm condition.
VAR_SCAN
– Time period in seconds over which the variability index (VAR_INDEX) is
computed.
VAR_INDEX
– Process variability index measured as the integral of average absolute error
between PV and its mean value over the previous evaluation period. This index is calculated
as a percent of OUT span and is updated at the end of the time period defined by
VAR_SCAN.
