DO1 - Backup Output Diverter
L025 5-7 DO1 When open, the controller output path is through the diverter
circuit diode to the final element. It is always in an opposite
state from DO0. (Not configurable.)

Alarms Related Datapoints
B335 5-9 CON0 Control Alarm Mode - Used to select one of six alarm types
or none. See Table 5-9 for details and examples.
1
C103 5-9 CON0 Alarm Limit 1 - Point in engineering units where an alarm is
triggered because the PV is not within the limit value set in
C103.
100
C104 5-9 CON0 Alarm Limit 2 - Point in engineering units where an alarm is
triggered because the PV is not within the limit value set in
C104.
0
C105 5-9 CON0 Alarm Dead Band - Sets the activation/deactivation gaps for
the alarm limit points. It is in engineering units.
2
Setpoint Related Datapoints
C114 5-9 CON0 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.
0
C125 5-9 CON0 Setpoint High Limit - It is the maximum control setpoint value
allowed.
100
C126 5-9 CON0 Setpoint Low Limit - It is the minimum control setpoint value
allowed.
0
C117 5-9 CON0 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
appears on the units display. A zero disables setpoint
slewing.

Miscellaneous Datapoints
A000 5-9 CON0 Tagname - Assignable 10 character name. CON-
0
A001 5-9 CON0 Engineering Units - Assignable 10 character designator. PER-
CENT
L109 5-9 CON0 Reverse Valve - Bottom of display output valve action
indicators: 1 = [O] [C] display order, 0 = [C] [O] display order.
