The Point Attributes feature lets a user monitor attributes of configured points through CimView. Configuring point attributes is as easy as configuring any expression in CimEdit.
Select or create an object to which the point attribute will be applied.
Open the object's Properties dialog box.
Click the to the right of the Expression field that applies to the object's
runtime behavior.
The Edit Expression dialog box opens.
Enter the Point ID and attribute you want to display using the following syntax.
'<POINT_ID>.<ATTRIBUTE_ID>'
Where
<POINT_ID> is the Point ID of any configured point
<ATTRIBUTE_ID> is one of the configuration attributes described in the point attributes documentation.
Important: You must enclose the syntax in single
quotes, because the '.' character is a
special character.

Point Attribute Guidelines
You can force an expression to
return a numeric value, if the value is a number but the attribute
is listed as returning a character. You use the operator
VAL to do this.
Example
VAL('DEV1750.ALARM_HIGH')+VAL(DEV1900.ALARM_HIGH')
Some of the attributes are
specific to points of a particular type. Valid point types, which
are specified in the attribute list, are:
All (point types)
Device
Derived (Virtual)
Global (Virtual)
All field names and enumerated
data are case insensitive.
