Blocks—AI Function Block
Description
Data Type: 101
Used to select the type of threshold that is used to
set the output.
Data Type: Float
Filter time of process variable
Contains the time constant for the rise time of the
Function Block output up to a value 63.21%
resulting from a jump on the input (PT1 filter).
Data Type: Unsigned8
Defines the reaction of the device, if a fault is
detected. The calculated ACTUAL_MODE remains
in AUTO.
If this parameter is not implemented, the AI
Function Block behaves like FSAFE_TYPE = 1
Data Type: Float
Default value for OUT parameter, if the status from
the primary value from the transducer block is bad.
Data Type: Float
Hysteresis. Prevents multiple triggering of the alarm
if the process variable is hovering around the
xx_LIM. Sensitivity is adjustable. Expressed as a
value below the high limit and above the low limit.
Data Type: Float
Value for upper limit of alarms. If the measured
variable is equal to or higher than the HI_HI_LIM
value the Limit Bit "high limited" in the Status Byte of
OUT and the HI_HI_Alarm bit in parameter
ALARM_SUM should be set to 1.
Data Type: Float
Value for upper limit of warnings. If the measured
variable is equal to or higher than the HI_LIM value
the Limit Bit "high limited" in the Status Byte of OUT
and the HI_Alarm bit in parameter ALARM_SUM
should be set to 1.
Data Type: Float
Value for lower limit of warnings. If the measured
variable is equal to or lower than the LO_LIM value
the Limit Bit "low limited" in the Status Byte of OUT
and the LO_Alarm bit in parameter ALARM_SUM
should be set to 1.
Data Type: Float
Value for lower limit of alarms. If the measured
variable is equal to or lower than the LO_LO_LIM
value the Limit Bit "low limited" in the Status Byte of
OUT and the LO_LO_Alarm bit in parameter
ALARM_SUM should be set to 1.
