When the data type of reference source CSPP element in the ENUM part is boolean type, map the reference source CSPP element to the DataVariable of the TwoStateDiscreteType VariableType. Map two CSPP elements of the ENUM part to Properties of the DataVariable based on the following rules.

• Assign the CSPP element with the CODE item value 0 to the FalseState Property and map the CSPP element with CODE item value 1 to the TrueState Property.
• When the LABEL2 item of the CSPP element is specified, set the item value to the text element of the Value Attribute for corresponding Property. Set the DATA item value of the Language element in the FILE_INFO part to the Locale element.
• When the LABEL2 item of the CSPP element is not specified, set the LABEL item value to the text element of the Value Attribute. Set "en-US" to the Locale element.
