Parameters

The new value for the attribute.

specifiedUOM

Type: OSIsoft.AF.UnitsOfMeasureUOM

The GetValue and SetValue calls of an attribute template are not forwarded to the associated data reference. When an attribute is created from this template, the template's value will be used as the default value. If a data reference is not configured for an attribute created from this template, then the attribute's value will continue to return the template's default value until the attribute's value is specifically set.

A value of any type may be written with SetValue. However, in order for a value to be saved, it must either be a .NET base type, a .NET serializable type, or support the PI SDK's IPIPersist interface. This means it is possible to write values such as arrays, System.Data.DataSet's, PISDK.PIPoint's, and references to other Application Framework objects. All DataReferences are not required to support all .NET types so the value must be compatible with the underlying DataReference.
