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.

C224 5-9 CON3 Controller Lower Range - Enter a value that represents in
engineering units the Loop 4 Control lower range value.

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).
