Program Methodology—At (@) Priority Status Indicators

PPCL (@NONE)
Unitary pre-APOGEE APOGEE BACnet
  
Syntax
@NONE
Use
This command identifies the PPCL priority level indicator. The
@NONE command can be used to test if a point currently is at PPCL
priority.
Example
The IF/THEN/ELSE statement would look like the following:
300 IF (SFAN.EQ.@NONE) THEN OFF(HORN)
Notes
For BACnet firmware, the field panel uses the slot corresponding to
the program's "Priority for Writing". The value of the point is set
based on the highest slot in the Command Priority Array; relinquish
default is used if the Command Priority Array is now empty.

Operator (@OPER)
Unitary pre-APOGEE APOGEE BACnet
  
Syntax
@OPER
Use
This command identifies the operator priority level indicator. The
@OPER command is typically used in one of the following situations:
• To test if a point is currently at operator priority, an
IF/THEN/ELSE statement would look like the following:
300 IF (SFAN.EQ.@OPER) THEN ON(HORN)
• To command a point to operator priority, an example of program
code might look like the following:
500 ON(@OPER,SFAN)
• To release a point from operator to PPCL priority, an example of
program code might look like the following:
700 RELEAS(@OPER,SFAN)
Notes
• For APOGEE and pre-APOGEE firmware, the @ priority indicator
must be used to release points in any priority to NONE.
• For BACnet firmware, the field panel releases the slot
corresponding to OPER in the Command Priority Table. The
value of the point is set based on the highest slot in the
Command Priority Array; relinquish default is used if the
Command Priority Array is now empty.
