• COV Limit (COV_LIMIT)
The Change Of Value (COV) Limit is the resolution in engineering units at which an
analog point value is reported over the network. This value is also used to establish a
dead band around high and low alarm limits for non-enhanced alarmable points. The
COV Limit data type is REAL.
• Current Value (CV)
This field represents a System 600 APOGEE point’s Current Value. The data type is
REAL. For some of the point types, these values have a corresponding textual
representation which better describes their state to the user. The textual representation is
what the user views. The REAL representation is what is used for calculations involving
the block.
• High Alarm Limit (HI_ALARM)
The Alarm Limit fields are only meaningful for System 600 APOGEE points defined as
Alarmable and defined without selecting the Enhanced Alarming Feature. The data type
is REAL and is expressed in the same engineering units as the point’s Present Value.
• Initial Value (IV)
The Initial Value is for FIX programming use. It allows the operator to set the value of a
tag when it is placed on scan. For example, turn the fans on before a batch is run. This
does not effect the initial value set in the field panels.
• Low Alarm Limit (LO_ALARM)
The Alarm Limit fields are only meaningful for System 600 APOGEE points defined as
Alarmable and defined without selecting the Enhanced Alarming Feature. The data is of
type REAL and is expressed in the same engineering units as the point’s Present Value.
• Point Priority (PRIORITY)
This field reflects either a point's current priority (if reading the point attribute) or desired
priority (if writing the point attribute). The priorities are listed here in ascending order,
NONE being the lowest priority and Operator being the highest.
