The point database is a file containing all information defined for every point in the System
600 APOGEE. The system controls points according to their definition and the purpose they
represent. Points are classified as follows:

ogi i i i ca ca ca cal l l l p p p p o o o o i i i i n n n n t t t t s s s s – A grouping of one to four physical and/or virtual point addresses under a

unique 30-character name. This name is referenced by operators, control programs, and the
other system features to command, examine, and store information for those points.

All logical points are composed of one or more of the four basic point types. The basic point
types are Analog Input (AI), Analog Output (AO), Digital Input (DI), and Digital Output (DO).
Table 4-1 lists all available logical point types used by the Trane system:

1 - Analog (multiple value
point–numeric only)

Logical Analog Input- Monitors one AI point. For example,
sensors for temperature, flow, pressure, and humidity.
L L L L A A A A O O O O
Logical Analog Output - Commands one AO point. For
example, positioners for dampers, valves, and motors.
L L L L D D D D I I I I
Logical Digital Input - Monitors one latched DI point. For
example, door contacts, smoke detectors, low
temperature detectors, and damper end switches.
L L L L D D D D O O O O
Logical Digital Output - Commands one latched DO point
for a two state (ON/OFF) device. For example, switches
for lighting and occupancy indication.
L L L L E E E E NU
NUM M M M
Logical ENUMerated - Control points that have multiple
NU
NU
numeric values. Each value is associated with a state text
entry. For example, a LENUM point can be a virtual point
that stores operational values for an SSTO application.
LENUMS are defined as virtual.
