Advanced Settings Dialog Box
The Activation field, which contains either a value or an WS tag, specifies, in seconds, the amount of time
each alarm in the Alarm Group must remain continuously in its alarm condition before becoming active. This
option is useful to avoid generating alarms on intermittent conditions (e.g.: noise). If this field is left in blank, the
alarm becomes active as soon as its condition is true.
The Normalization field, which contains either a value or an WS tag, specifies, in seconds, the amount of time
each alarm in the Alarm Group must remain continuously out from its alarm condition before becoming
normalized. This option is useful to avoid normalizing alarms on intermittent conditions (e.g.: noise). If this field
is left in blank, the alarm becomes normalized as soon as its condition is no longer true.
The Time Stamp/Value field is a combo-box that lets you select the type of time stamp to be maintained by the
Tag for the last significant Alarm activity, along with the value of the Tag at that time. You can select the type of
activity that updates the time stamp:
• Activation/Norm (default): The time when the dead band ended — that is, when the alarm becomes
activated or normalized.
• Last Tag Change: The time when the value of the tag last changed during the dead band.
• Start Condition: The time when the dead band started.
The Email Settings button opens a dialog
box that allows you to specify settings for
email messages that can be sent when
Alarms occur. Email (SMTP) setting must
be configured prior to use of the Alarm
Emails. Attachments are not allowed in this
dialog, but attachments can be emailed
using WS built-in functions.
