The point status indicates the current condition of a logical point as defined in the System
600 APOGEE database. It can also reflect two or more statuses. For example, a point may be
in alarm and failed at the same time, in which case the status would be *AF*. Table 4-3
gives an explanation of each status.

-N-
NORMAL
The point is in regular operation. The value and alarm
conditions of the point can be updated by control
programs or operator commands.
*A*
ALARM
The condition of the point is outside its defined limits
and an alarm priority has been assigned to the point.
An alarm occurs when: the value of an analog point is
outside a defined high or low limit. The value of a
proof point does not correspond to the commanded
value of the associated output point within the proof
delay time. An LDI or LDO point is ON and the point
was defined to go into alarm when it turns ON. An
example is a smoke detector point.
*A
n
*
ALARM
The condition of the point is outside its defined limits
and an enhanced alarm priority has bee assigned to
the point. The
n
represents the number of the alarm
level.
*AC*
ALARM-BY-
COMMAND
The value of a point in its normal operating range,
however the point has been commanded into alarm
by an operator or by the control program. The point
remains in this state until it is commanded back to
the Normal state by an operator or control program.
*ACK*
ACKNOWLEDGE
The point is in alarm and has been acknowledged by
a user.
*F*
FAILED
The field panel is unable to command or read any of
the physical points associated with the logical point.
This may be the result of hardware failure or a sensor
reading outside of its defined limits.
*O*
OPERATOR
DISABLED
The point has been disabled by an operator. The
point value and alarm conditions are not reported to
the BLN and cannot be updated by operator
commands or control programs until the point is
commanded back to Enabled.
