Data-
point Table Module Title and Function
Default
AI1 - Remote Setpoint Primary (Is affected by Setpoint Related Datapoints) (Cont)
L441 5-4 AI1 Square Root Signal - It is used if the Primary Variable Loop
Remote Setpoint signal is a squared nonlinear value. 0 =
input is already linear; 1 = square root to restore
linearization. 0
AI2 - Limiting Variable Loop
C258 5-4 AI2 Engineering Span - Set to 100 by CS22; however, it can be
changed. Enter a value, that when added to the
Engineering Zero value, will produce an upper range value
in engineering units that represents the Limiting Variable
Loop transducer upper range signal value. 0
C278 5-4 AI2 Engineering Zero - Enter a value that represents in
engineering units the Limiting Variable Loop transducer
lower range signal value. 0
B271 5-4 AI2 Digital Filter Index - This is a first order filter that can be
applied to the Limiting Variable Loop transducer signal. See
Table 5-4 for input values. 3
L418 5-4 AI2 0-5 V Input - Enter a value that matches the signal voltage
range of the Limiting Variable Loop transducer 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 Limiting 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
AI3 - Remote Setpoint Limiting (Is affected by Setpoint Related Datapoints)
L139 5-9 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 Limiting Variable Loop Remote
Setpoint to become the value used as the control setpoint if
the R/L push button is in Remote. 0
C148 5-9 CON1 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. 0
C149 5-9 CON1 Remote Setpoint Ratio (K1) - See Remote Setpoint bias (B1)
above. 1
C259 5-4 AI3 Engineering Span - Enter a value, that when added to
Engineering Zero, will produce an upper range value in
engineering units that represents the Limiting Variable Loop
Remote Setpoint upper range signal value. 0
C279 5-4 AI3 Engineering Zero - Enter a value that represents in
engineering units the Limiting Variable Loop Remote
Setpoint lower range signal value. 0
