Program Methodology—Point Status Indicators
Siemens Building Technologies, Inc. 1-93
Night mode (NGTMOD)
Unitary pre-APOGEE APOGEE BACnet
Syntax
if (pt1.eq.NGTMOD) then...
pt1 A point name whose operational status is compared to the
status indicator.
• This parameter must be defined as an LCTLR point
type.
Use
This status indicator determines if an equipment controller is in
NIGHT mode.
For some equipment controllers, NIGHT mode is also referred to as
UNOCC (unoccupied) mode. If an equipment controller is in
unoccupied mode, PPCL recognizes this status as NGTMOD.
Example
200 IF (CNTRL1.EQ.NGTMOD) THEN NGTSP = 78.0
Notes
This point is only valid for equipment controllers and is only valid
when used with the LCTLR point type or LTCU (pre-APOGEE only)
point type.

Off (OFF)
Unitary pre-APOGEE APOGEE BACnet
Syntax
if (pt1.eq.OFF) then...
pt1 A point name whose operational status is compared to the
status indicator.
• This parameter must be defined as an LDI, LDO,
L2SP, L2SL, LOOAL, LOOAP, LFSSL, or LFSSP
point type.
Use
This status indicator determines if a point (pt1) is in the OFF state.
This comparison is true if the point status is OFF.
Example
200 IF (FAN.EQ.OFF) THEN RTDAMP = 3.0
