Title and Function

Default

AI0 - Primary Variable Loop

C256

5-4

AI0

Engineering Span - Enter a value, that when added to the
Engineering Zero value, will produce an upper range value
in engineering units that represents the Primary Variable
Loop transducer upper range signal value.

100

C276

5-4

AI0

Engineering Zero - Enter a value that represents in
engineering units the Primary Variable Loop transducer
lower range signal value.

0

B269

5-4

AI0

Digital Filter Index - This is a first order filter that can be
applied to the Primary Variable Loop transducer signal. See
Table 5-4 for input values.

L416

5-4

AI0

0-5 V Input - Enter a value that matches the signal voltage
range of the Primary Variable Loop transducer. 1 = 0 - 5 V
range; 0 = 1 - 5 V range.

0

L440

5-4

AI0

Square Root Signal - It is used if the Primary Variable Loop
transducer is a nonlinear differential pressure (DP) cell that
provides a squared signal value. 0 = input is already linear;
1 = square root to restore linearization.

0

AI1 - Remote Setpoint Primary (Is affected by Setpoint Related Datapoints)

L115

5-9

CON0

Remote Setpoint Enable - This datapoint is controlled by
DI0. When DI0 is a closed contact, this datapoint is set to 1
to allow the modified Primary Variable Loop Remote
Setpoint to become the value used as the control setpoint if
the R/L push button is in Remote.

0

C112

5-9

CON0

Remote Setpoint Bias (B1) - This datapoint and Remote
Setpoint Ratio (K1) allow the Remote Setpoint input to be
modified by the Setpoint Generator.
Setpoint = [Remote Setpoint X Ratio] + Bias
SP = [RSP X K1] + B1
The B1 and K1 datapoints are modified when the input
signal must be scaled to match the setpoint range desired.

C113

5-9

CON0

Remote Setpoint Ratio (K1) - See Remote Setpoint bias (B1)
above.

Engineering Span - Enter a value, that when added to the
Engineering Zero value, will produce an upper range value
in engineering units that represents the Primary Variable
Loop Remote Setpoint upper range signal value.

AI1

Engineering Zero - Enter a value that represents in
engineering units the Primary Variable Loop Remote
Setpoint lower range signal value.

Digital Filter Index - This is a first order filter that can be
applied to the Primary Variable Loop Remote Setpoint
signal. See Table 5-4 for input values.

0-5 V Input - Enter a value that matches the voltage range of
the Primary Variable Loop Remote Setpoint signal. 1 = 0 - 5
V range; 0 = 1 - 5 V range.
