L114 5-9 CON0 Auto Enable - Secondary Setpoint Transmit output is from
the Primary PID algorithm when set to 1 and the A/M push
button is in Auto. 1
C115 5-9 CON0 Controller Span - Enter a value, that when added to the
Primary Controller Lower Range value, will produce the
Primary Controller upper range value in engineering units. 100
C116 5-9 CON0 Controller Lower Range - Enter a value that represents in
engineering units the Primary Controller lower range value. 0
DI0 - Cascade Enable
L264 5-6 DI0 Contact Input Invert - Normally, Cascade Enable is permitted
if DI0 is closed. Set to 1 to reverse the DI0 condition
required to permit Cascade Enable (DI0 open = Cascade
Enable). 0
DI1 - Remote Enable Primary
L265 5-6 DI1 Contact Input Invert - Normally, Remote Enable Primary is
permitted if DI1 is closed (datapoint L115 - Remote Setpoint
Enable is set to 1 by DI1). Set to 1 to reverse the DI1
condition required to permit Remote Enable Primary (DI1
open = Remote Enable Primary). 0
DO0 - Process Alarms Secondary
L288 5-7 DO0 Contact Output Invert - Normally, Process Alarms Secondary
is enabled if DO0 is closed. Set to 1 to reverse the DO0
condition required to activate Process Alarms Secondary
(DO0 open = the Secondary PV value is not within the C139,
C140 Alarm Limits). 0
DO1 - Process Alarms Primary
L289 5-7 DO1 Contact Output Invert - Normally, Process Alarms Primary is
enabled if DO1 is closed. Set to 1 to reverse the DO1
condition required to activate Process Alarms Primary (DO1
open = the Primary PV value is not within the C103, C104
Alarm Limits). 0

CON1 Control Alarm Mode - Used to select one of six alarm types
or none. See Table 5-9 for details and examples. 1
C103,
C139 5-9 CON0
CON1 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. 100
C104,
C140 5-9 CON0,
CON1 Alarm Limit 2 - Point in engineering units where an alarm is
triggered because the PV is not within the limit value set in
the datapoint. 0
C105,
C141 5-9 CON0,
CON1 Alarm Dead Band - Sets the activation/deactivation gaps for
the alarm limit points. It is in engineering units. 2
