Default values

As copied from palettes or originated from “manager” views, some components already have default values in certain BFormat-type properties (while others may default as empty). A few examples of those components with default values are listed in Table 1.

Table 1. Default values for a few properties using Format data type

Component	Property	Default Value	Notes
Alarm extension for points, e.g. OutOfRangeExt, etc.	sourceName	%parent.displayName%	Suitable “as is” in many cases, for example where all parent points are uniquely named.
History extension for points, e.g. NumericInterval, etc.	historyName	%parent.name%
Any network component’s AlarmSourceInfo slot.	sourceName	%parent.displayName%	Often both properties are left at default values.
Any device-level component’s AlarmSourceInfo slot.	sourceName	%parent.parent.displayName% %parent.displayName%	Often both properties are left at default values.
EmailRecipient	subject	Niagara Alarm From %alarmData.sourceName%	Much additional alarm data is used in the “body” slot.

Note that in the property value, you can use multiples of scripted variables along with “static text,” as done in defaults for a device’s AlarmSourceInfo “sourceName” property (a static space character separates the “%parent.parent.displayName%” from “%parent.displayName%”. The subject property of the EmailRecipient contains static text "Niagara Alarm From " ahead of the variable.
