Program Methodology—Point Status Indicators
Siemens Building Technologies, Inc. 1-85
Auto (AUTO)
Unitary pre-APOGEE APOGEE BACnet
Syntax
if (pt1.eq.AUTO) then...
pt1 A point name whose operational status is compared to the
status indicator.
• This parameter must be a LOOAP or LOOAL point
type.
Use
This status indicator determines if a point (pt1) is in the AUTO state.
This comparison is true if the point status is AUTO.
Example
200 IF (HOAFAN.EQ.AUTO) THEN ON(LIGHT3)

Battery status—discharged (DEAD)
Unitary pre-APOGEE APOGEE BACnet
Syntax
if ($BATT.eq.DEAD) then...
Use
This status indicator compares the value of the $BATT resident point
to determine if the backup battery is discharged. This comparison is
true if the battery is discharged.
Example
600 IF ($BATT.EQ.DEAD) THEN ALARM(P26BAT)
An alternate method to test the battery strength is to use the numeric
value (0) of DEAD.
600 IF ($BATT.EQ.0) THEN ALARM(P26BAT)
Notes
This function can only be used in field panels that have the ability to
monitor the strength of their backup battery.
