• Descriptor (DESCRIPTIOR)
All System 600 APOGEE logical points allow the assignment of a point descriptor. This
descriptor is an ASCII string of twelve alphanumeric characters (blank spaces are
allowed). It is used to provide additional information to an operator when displaying
points. Descriptors are not used by either the system or operator to call up displays or to
command points. Therefore, there is no need for them to be unique and they may be null
(all characters 0x00). Unused characters must be padded with null terminators (0x00).
• Engineering Units (ETAG)
The Engineering Units field defines the engineering units associated with the present
value of analog and pulse accumulator points (for example, " DEG F" or "KWH"). The
field is composed of a text string. The string is used for reference purposes, and it has no
effect on numerical representation or calculation of any point property. The string need
not be unique. Unused characters must be padded with null terminators (0x00). The units
field may also contain a null string.
• Enhanced Alarms (ENH_ALARM)
This indicates that the point was defined to support the System 600 APOGEE Enhanced
Alarming feature.
• Totalize (TOTAL_ENB)
This indicates that the point was defined as enabled for Totalization. Totalized data is
maintained locally at the point’s local System 600 APOGEE controller.
• Totalize in Hours (TOTAL_HOURS)
This indicates that the point’s Totalization Interval is defined as hourly; otherwise, every
five minutes. If Totalization is not enabled for this point, this indication is meaningless.
Point Command Field Descriptions
The following fields can be commanded for a point.
• Print (PRINT)
This is a toggle switch that allows an operator to enable and disable alarm printing for a
point. If a light button is chosen for this representation, the current state will be indicated.
• Service (SERVICE)
This toggle switch allows an operator to put a point into and out of service. Again, if a
light button is used the current state will be indicated.
• Normal (NORMAL)
This toggle allows an operator to put a point into alarm or into a normal state. A light
button will indicate current status.
