Data-
point Table Module Title and Function
Default
AI3 - Remote Setpoint Limiting (Is affected by Setpoint Related Datapoints) (Cont)
B272 5-4 AI3 Digital Filter Index - This is a first order filter that can be
applied to the Limiting Variable Loop Remote Setpoint
signal. See Table 5-4 for input values.
3
L419 5-4 AI3 0-5 V Input - Enter a value that matches the signal voltage
range of the Limiting Variable Loop Remote Setpoint signal.
1 = 0 - 5 V input range; 0 = 1 - 5 V input range.
0
L443 5-4 AI3 Square Root Signal - It is used if the Limiting Variable Loop
Remote Setpoint input is a squared signal value that must
be linearized. 0 = input is already linear; 1 = square root to
restore linearization.
0
AO0 - Control Output Limiting (Primary, Limiting)
L472 5-5 AO0 0-20 mA Output - 0 = 4-20 mA signal; 1 = 0-20 mA signal.
Enter a value to match the output valve requirements.

Manual Fallback Disable - 0 = always power up in manual; 1
= auto/manual selector unchanged at power up.

Hard Manual Limit - 1 = apply output limits to the final output
of the Auto-Manual generator. Affects both the manual push
buttons and the controller’s result. 0 = do not apply limits.

CON1
Output High Limit - Sets maximum Control Output Limiting
signal value for in engineering units.

5-9 CON0,
CON1
Output Low Limit - Sets minimum Control Output Limiting
signal value in engineering units.

CON1
Output Slew Rate - It is a rate limit applied to the output
value. When configured to a non-zero value, the output
from the Auto-Selector is only allowed to change by this
amount each scan time. A zero disables output slewing. It
does not affect manual operation.
0
CON0 Control Related Datapoints
C106 5-9 CON0 Proportional Band - Is the percent of error required to move
the output full scale for proportional action.
100
C107 5-9 CON0 Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset.
0
C108 5-9 CON0 Rate Time - Represents the minutes proportional action is
advanced.
0
C111 5-9 CON0 Manual Reset - It determines the output valve position when
the controller is in Auto and the error = 0. It is mutually
exclusive with Reset Time.

L114 5-9 CON0 Auto Enable - Controller output is from a PID algorithm when
set to 1 and A/M push button is in Auto.

C115 5-9 CON0 Controller Span - Enter a value, that when added to the
Primary Controller Lower Range value, will produce the
control upper range value in engineering units.
