Tags and the Project Database
Tag Property Description R or R/
W
If you manually set this value to 1, then the
active alarms (if any) are acknowledged. The
value of this property is always the opposite of
the Ack property.
Data Type
Available on Data Type…
Bool Int Real Str
Retain
AlrAckValue
AlrOffValue
AlrOnValue
AlrDisable
Text associated with the Acknowledged state
of a Boolean tag. This text is displayed in the
Value column of an Alarm/Event Control.
You can also edit this text in the Tag Properties
dialog (Alarms – Bool Type).
Text associated with the Normalized state of a
Boolean tag. This text is displayed in the Value
column of an Alarm/Event Control.
You can also edit this text in the Tag Properties
dialog (Alarms – Bool Type).
Text associated with the Active state of a
Boolean tag. This text is displayed in the Value
column of an Alarm/Event Control.
You can also edit this text in the Tag Properties
dialog (Alarms – Bool Type).
This property can have two values:
• 0: The alarms associated with this tag are
enabled. This means that when an alarm
condition occurs, the alarm will become
active.
• 1: The alarms associated to this tag are
disabled. This means that even if an
alarm condition occurs, the alarm will not
become active.
R/W String, up to 32 chars Y N N N Y
R/W String, up to 32 chars Y N N N Y
R/W String, up to 32 chars Y N N N Y
R/W Boolean Y Y Y N N
Note:
• If a property is marked "n/a" with regards to being retentive, it's because the property is inherent
in the tag definition (e.g., Name, Size) or the value of the property is continuously derived during
runtime (e.g., alarm activation, DisplayValue). To enable retention for a tag, select the Retentive
Parameters option in the Tag Properties dialog.
• If the project attempts to write a value outside of the range specified in the Min and Max properties,
the Tags Database will not accept the new value and a warning message is written in the Output
window. If both Min and Max properties are configured with the value 0 (zero), it means that any
value applied to the tag type will can be written to the tag.
• You cannot use tag properties (such as Bit fields) to configure Alarm or Trend worksheets.
• Although you can apply tag properties to System Tags, those properties will not persist when you
download your project to a CE device.
