The alarm system in PanelView notifies an operator when specific
trigger values appear at specific controller addresses.
Before the terminal can display alarms, you must:
•
define the alarms in your application
•
program the logic controller to generate the alarms
!
ATTENTION: Do not rely on your terminal as a
primary warning device in applications that could
result in physical injury, product damage or significant
process down time.
All critical alarm indications and any critical logic
controller responses must employ redundant and
hard-wired or mechanical interlocks.
In PanelBuilder, you define a series of alarms. For each alarm, you
define a message and a trigger value. You can also specify whether
the alarm must be acknowledged, displayed and/or printed.
You must also define the trigger tag that links the alarm messages
and the controller program. The program monitors values for alarm
conditions. When the program detects an alarm condition, it sets the
bit or value at the address defined by the trigger tag. The terminal
reads this value and triggers the corresponding alarm.
For example, to monitor the level of a tank, define an alarm with a
trigger value of 1 and the message text “Tank too Full”. Then
program the controller to set the bit (1) at the trigger address when
the tank is full. This triggers the message “Tank too Full”.
