4.5 Analog Input Block
The ANALOG INPUT (AI) block takes the Transducer
Block input data, selected by channel number, and makes it
available to other function blocks at its output:
1. Level
2. Volume
3. Interface
4. Interface Volume
Scaling
4.5.1 AI Block Parameters
The first eight parameters in an AI block are the standard
block parameters discussed in section 4.1.1. Additional
analog input function block parameters are as follows:
BATCH: A parameter intended to be used in Batch applica-
tion in line with IEC 61512 Part 1.
OUT: Contains the current measurement value in the con-
figuration engineering unit.
PV_SCALE: High and low scale values used to convert
Process Variable Configured by channel into percent.
OUT_SCALE: The high and low scale values, the engineer-
ing code, and number of digits to the right of the decimal
point to be used in displaying the OUT parameters.
LIN_TYPE: Type of linearization. No linerization is sup-
ported in the AI function blocks.
CHANNEL: Selects the measurement value from an active
transducer block as the input to the function block.
PV_FTIME: Filter time of the Process Variable.
FSAFE_TYPE: Defines the reaction of a device, if a fault is
detected and the quality of the process variable input from
the transducer block is BAD.
0 = FSAFE_VALUE is used as OUT
1 = Use last stored valid OUT value
2 = OUT has incorrect calculated value; status
remains “bad”.
FSAFE_VALUE: Default value for the OUT parameter, if a
fault is detected, and FSAFE_TYPE is 0.
HI_LIM: Value of the upper limit of warnings.
LO_LIM: Value of the lower limit of warnings.
ALARM_HYS: Hysteresis to adjust sensitivity of alarm
triggering.
HI_HI_LIM: Value of the upper limit of alarms.
HI_LIM: Value of the upper limit of warnings.
LO_LIM: Value of the lower limit of warnings.
