Table 13-3. CS22 Two Loop Override Controller Datapoints
Data-
point Table Module 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.
3
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.
0
C113 5-9 CON0 Remote Setpoint Ratio (K1) - See Remote Setpoint bias (B1)
above.
1
C257 5-4 AI1 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.
0
C277 5-4 AI1 Engineering Zero - Enter a value that represents in
engineering units the Primary Variable Loop Remote
Setpoint lower range signal value.
0
B270 5-4 AI1 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.
3
L417 5-4 AI1 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.
