Title and Function

Default

DO0 - Process Alarms Primary

L288

5-7

DO0

Contact Output Invert - Normally, Process Alarms Primary is
enabled if DO0 is closed. Set to 1 to reverse the DO0
condition required to activate Process Alarms Primary (DO0
open = the Primary Variable value is not within the C103,
C104 Alarm Limits).

0

DO1 - Process Alarms Limiting

L289

5-7

DO1

Contact Output Invert - Normally, Process Alarms Limiting is
enabled if DO1 is closed. Set to 1 to reverse the DO1
condition required to activate Process Alarms Limiting (DO1
open = the Limiting Variable value is not within the C139,
C140 Alarm Limits).

Control Alarm Mode - Used to select one of six alarm types
or none. See Table 5-9 for details and examples.

Alarm Limit 1 - Point in engineering units where an alarm is
triggered because the loop PV is not within the limit value
set in the datapoint.

C104,
C140

CON0,
CON1

Alarm Limit 2 - Point in engineering units where an alarm is
triggered because the loop PV is not within the limit value
set in the datapoint.

CON0,
CON1

Alarm Dead Band - Sets the activation/deactivation gaps for
the alarm limit points. It is in engineering units.

Setpoint Related Datapoints (Primary, Limiting)

C114,
C150

5-9

CON0,
CON1

Control Zone - A gap on both sides of setpoint. When PV is
within this gap, the proportional and integral output changes
are suppressed. Derivative output is unaffected.

CON0,
CON1

Setpoint High Limit - It is the maximum loop control setpoint
value allowed.

100

C126,
C162

5-9

CON0,
CON1

Setpoint Low Limit - It is the minimum loop control setpoint
value allowed.

0

C117,
C153

5-9

CON0,
CON1

Setpoint Slew Rate - It is a rate limit applied to the setpoint.
When configured to a non-zero value, the setpoint used in
the PID algorithm is only allowed to change by this amount
each scan time. The final value of the setpoint always ap-
pears on the units display. A zero disables setpoint slewing.

Reverse Valve - Bottom of display loop output valve action
indicators: 1 = [O] [C] display order, 0 = [C] [O] display
order. (Reverse Valve indicators appear on the Single Loop
CON0 and Single Loop CON1 displays only.)
