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 automation stations that have the ability to monitor the strength of their backup battery.
