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.

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

AI2

Engineering Span - Enter a value, that when added to
Engineering Zero, will produce an upper range value in
engineering units that represents the Loop 1 Remote
Setpoint upper range signal value.

AI2

Engineering Zero - Enter a value that represents in
engineering units the Loop 1 Remote Setpoint lower range
signal value.

AI2

Digital Filter Index - This is a first order filter that can be
applied to the Loop 1 Remote Setpoint signal. See Table 5-4
for input values.

AI2

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

0

L442

5-4

AI2

Square Root Signal - It is used if the Loop 1 Remote Setpoint
input is a squared signal value that must be linearized. 0 =
input is already linear; 1 = square root to restore linearization.

AI3 - Remote Setpoint Loop 2 (Is affected by Setpoint Related Datapoints)

L139

CON1

Remote Setpoint Enable - This datapoint is controlled by DI1.
When DI1 is a closed contact, this datapoint is set to 1 to
allow the modified Loop 2 Remote Setpoint to become the
value used as the control setpoint if the R/L push button is in
Remote.

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.
