DI0 - Remote Enable Loop 1
Contact Input Invert - Normally, Remote Enable Loop 1 is
permitted if DI0 is closed (datapoint L115 - Remote Setpoint
Enable is set to 1 by DI0). Set to 1 to reverse the DI0
condition required to permit Remote Enable Loop 1 (DI0
open = Remote Enable Loop 1).
DI1 - Remote Enable Loop 2
Contact Input Invert - Normally, Remote Enable Loop 2 is
permitted if DI1 is closed (datapoint L139 - Remote Setpoint
Enable is set to 1 by DI1). Set to 1 to reverse the DI1
condition required to permit Remote Enable Loop 2 (DI1
open = Remote Enable Loop 2).
DO0 - Process Alarm Loop 1
Contact Output Invert - Normally, Process Alarm Loop 1 is
enabled if DO0 is closed. Set to 1 to reverse the DO0
condition required to activate Process Alarm Loop 1 (DO0
open = the Loop 1 PV value is not within the C103, C104
Alarm Limits).
DO1 - Process Alarm Loop 2
Contact Output Invert - Normally, Process Alarm Loop 2 is
enabled if DO1 is closed. Set to 1 to reverse the DO1
condition required to activate Process Alarm Loop 2 (DO1
open = the Loop 2 PV value is not within the C139, C140
Alarm Limits).
Alarms Related Datapoints (Loop 1, Loop 2)
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.
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.
Alarm Dead Band - Sets the activation/deactivation gaps for
the alarm limit points. It is in engineering units.
Setpoint Related Datapoints (Loop 1, Loop 2)
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.
Setpoint High Limit - It is the maximum loop control setpoint
value allowed.
Setpoint Low Limit - It is the minimum loop control setpoint
value allowed.
