→Generic data type
according to →IEC-standard: →data type which represents more than one type of data
logi.CAD 3 is using generic data types for certain inputs/outputs resp. return values in some system blocks for the application. Compare: →Overloading and →Typed
Here the hierarchy of the generic data types and the appropriate elementary data types:

Note on how to interpret the table: If the last column does not list elementary data types for a generic data types, this generic data type includes the elementary data types of those generic data types that are subordinated.
Example 1: The generic data type ANY is the highest possible generalization of the data types. Hence, ANY includes all elementary data types (ANY_ELEMENTARY) and all derived data types (ANY_DERIVED).
Example 2: The generic data type ANY_INT includes the elementary data types of the subordinated generic data types ANY_UNSIGNED and ANY_SIGNED. Hence, ANY_INT includes: USINT, UINT, UDINT, ULINT, SINT, INT, DINT, LINT
