AO0 - Control Out (Cont)
C118 5-9 CON0 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 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 the PID algorithm
when set to 1 and A/M push button is in Auto.
1
C115 5-9 CON0 Controller Span - Enter a value, that when added to the
Controller Lower Range value, will produce the control upper
range value in engineering units.
100
C116 5-9 CON0 Controller Lower Range - Enter a value that represents in
engineering units the control lower range value.
0
DI0 - Force Output Tracking
L264 5-6 DI0 Contact Input Invert - Normally, Force Output Tracking is
enabled if DI0 is open (and datapoint L119 - Enable Output
Tracking = 1). Set to 1 to reverse the DI0 condition required
to activated output tracking (DI0 closed = Force Output
Tracking).
0
DI1 - Ratio Enable
L265 5-6 DI1 Contact Input Invert - Normally, Ratio Enable is permitted if
DI1 is closed. Set to 1 to reverse the DI1 condition required
to activate Ratio Enable (DI1 open = Ratio Enable).
0
DO0 - Process Alarm 1
L288 5-7 DO0 Contact Output Invert - Normally, Process Alarm 1 is enabled
if DO0 is closed. Set to 1 to reverse the DO0 condition
required to activate Process Alarm 1 (DO0 open = the PV
value is not within the C103 limit).
0
DO1 - Process Alarm 2
L289 5-7 DO1 Output Invert - Normally, Process Alarm 2 is enabled if DO1
is closed. Set to 1 to reverse the DO1 condition required to
activate Process Alarm 2 (DO1 open = the PV value is not
within the C104 limit).
