Value ON if 1A2 is active alarm
and [Current in Alarm]
and [Alarm not acknowledged]
In the above example, the ON or OFF value of the global binary
is determined by the alarm status of analog input #2 on satellite
controller #1. When an alarm occurs, the alarm message will blink
on the Analog Input Screen. After the alarm has been acknowledged,
one of two things will happen. If the value of the analog input is
presently within the alarm limits, the alarm message will disappear.
If the value of the analog input is still outside the alarm limits, the
message will stay on the screen, but it will quit blinking.
The term “active alarm” means that the alarm has not been cleared.
It is either a “blinking” or “solid” alarm within the system.
The conditional statements are in a “choice” fi eld and therefore the
choices are shown at the bottom of the screen.
CHOICES:
[NONE]
[NONE] When NONE is selected for both of the choice
fi elds, the value of the global binary will change
state (go ON in the above example) whenever the
analog input specifi ed on this screen is in an alarm
condition, either unacknowledged (“blinking”
alarm) or acknowledged (“solid” alarm).
[NONE]
[Alarm
Acknowledged] When these choices are selected, the value of the
global binary will go ON when the alarm for the
analog input is acknowledged while the value of
the analog input is outside the alarm limits. That is
to say, the global binary will go ON whenever this
analog input has “solid” alarm condition.
[NONE]
[Alarm Not
Acknowledged] When these choices are selected, the value of
the global binary will go ON when the alarm for
the analog input has not been acknowledged and
remains a “blinking” alarm.
[Current in
Alarm]
[NONE] When these choices are selected, the value of the
global binary will go ON when the value of the
analog input is outside of the alarm limits.
[Current in
Alarm]
[Alarm
Acknowledged] When these choices are selected, the value of the
global binary will go ON while the value of the
analog input is outside the alarm limits and the
alarm has been acknowledged (“solid” alarm).
[Current in
Alarm]
[Alarm not
Acknowledged] When these choices are selected, the value of the
global binary will go ON while the value of the
analog input is outside the alarm limits and the
alarm is unacknowledged (“blinking” alarm).
[Not in Alarm]
[NONE When these choices are selected, the value of
the global binary will] go ON when the value of
the analog input returns inside the alarm limits,
regardless of whether it has been acknowledged or
not.
[Not in Alarm]
[Alarm
Acknowledged] When these choices are selected, the value of
the global binary will go ON when the value of
the analog input returns inside the alarm limits,
provided it was acknowledged while it was outside
the alarm limits.
[Not in Alarm]
Acknowledged] When these choices are selected, the value of
the global binary will go ON when the value of
the analog input returns inside the alarm limits,
provided it was not acknowledged while it was
outside the alarm limits.
