C223 5-9 CON3 Controller Span - Enter a value, that when added to the Loop
4 Control Lower Range value, will produce the Control upper
range value in engineering units. 100
C224 5-9 CON3 Controller Lower Range - Enter a value that represents in
engineering units the Loop 4 Control lower range value. 0
C220 5-9 CON3 Remote Setpoint Bias (B1) - This datapoint and Remote
Setpoint Ratio (K1) allow the CON1

DI0 - #1 Cascade Enable
L264 5-6 DI0 Contact Input Invert - Normally, #1 Cascade Enable is
permitted if DI0 is closed. Set to 1 to reverse the DI0
condition required to permit #1 Cascade Enable (DI0 open =
#1 Cascade Enable). 0
DI1 - #2 Cascade Enable
L265 5-6 DI1 Contact Input Invert - Normally, #2 Cascade Enable is
permitted if DI1 is closed. Set to 1 to reverse the DI1
condition required to permit #2 Cascade Enable (DI1 open =
#2 Cascade Enable). 0
DO0 - #1 Secondary Process Alarms
L288 5-7 DO0 Contact Output Invert - Normally, #1 Secondary Process
Alarms is enabled if DO0 is closed. Set to 1 to reverse the
DO0 condition required to activate #1 Secondary Process
Alarms (DO0 open = the Secondary PV value is not within
the C175, C176 Alarm Limits). 0
DO1 - #2 Secondary Process Alarms
L289 5-7 DO1 Contact Output Invert - Normally, #2 Secondary Process
Alarms is enabled if DO1 is closed. Set to 1 to reverse the
DO1 condition required to activate #2 Secondary Process
Alarms (DO1 open = the Secondary PV value is not within
the C211, C212 Alarm Limits). 0

CON3 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
C176,
C212 5-9 CON2,
CON3 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
C177,
C213 5-9 CON2,
CON3 Alarm Dead Band - Sets the activation/deactivation gaps for
the alarm limit points. It is in engineering units. 2
