The format for defining a default value for an enumerated data type is:
- TYPE
- <Enumerated Data Type Name>: (<Data Type>, <Data Type>) :=<Default Value>;
- END_TYPE
Example:
- TYPE
- ControlStatus: (Healthy, Overrange, Failed):=Failed;
- END_TYPE
In the example, ControlStatus is the name of the enumerated data type. Healthy, Overrange, and Failed are the names that are applied to the state values as part of the enumerated data type definition. The default value of the enumerated data type is set to Failed.
