ATTENTION: Do not use your PanelView terminal as a
primary warning device or indicator of a critical or dangerous
situation. An operator’s response to a critical or dangerous
situation must never depend on software or solid state
electronics. All critical alarm indications and any critical host
controller responses must employ redundant and hard wired or
mechanical interlocks. “Critical” means any situation that could
result in physical injury, product damage or significant process
down time.
Alarm Messages
When the PLC controller triggers an alarm message, PanelView displays
the alarm message in the Alarm window. Time and date of occurrence are
displayed with the alarm message.

The Full Alarm window can display up to 19 single-height messages. If the
PLC controller triggers more alarm messages before you clear the window,
the existing message shifts down, and the new messages are added to the
top of the list.
