event, this property also specifies the amount of time for which the alarm
condition must no longer exist before subsequent reactivations will result in a
further alarm being signaled. As an example, if an alarm is set to activate when a
speed switch indicates that a motor is not running even when the motor has been
requested to start, this property can be used to provide the motor with time to
run-up before the alarm is activated.
• The Accept property is used to indicate whether the user will be required to
explicitly accept an alarm before it will no longer be displayed. Edge triggered
alarms must always be manually accepted.
• The Priority property is used to control the order in which alarms are displayed
by Fieldbus Gateway Manager’s alarm viewer. The lower the numerical value of
the priority field, the nearer to the top the alarm will be displayed.
• The Email property is used to specify the email address book entry to which a
message should be sent when this alarm is activated. Refer to the Advanced
Communications chapter for information on configuring email.
• The Siren property is used to indicate whether or not the activation of this alarm
should also activate the Fieldbus Gateway’s internal sounder. While the sounder
is active, the Gateway’s display will also flash to better draw attention to the
alarm condition.
