VARIABLES AND VALUES
Scripts and expressions are made up of variables and values, which are defined as follows:
Variables: Object properties act as variables. They are written as follows:
[object tag name].[property name]
where [object tag name] is an object’s script tag, and [property name] is a property of that particular type of object. For example, the following are
all valid variables:
Door_Alarm.Value
DVR2.CommStatus
Alarm_Timer.NO
Values: Property values act as values that variables can be compared to. They are written as follows:
[object tag name].[property value name]
where [object tag name] is an object’s script tag, and [property value name] is a value of that particular object property. For example, the
following are all valid property values:
Door_Alarm.True
DVR2.Online
Alarm_Timer.True
Other possible values are the following:
•Numeric values
•Boolean values: False, True (or 0, 1)
Refer to Properties of Objects for a list of valid object properties and values.
