Tag Data Type conversion are converted as follows:

- TIA Portal Tag Table Data Types
- TIA Portal Program Block Data Types

:::hint{type="info"}
**Notes**:

- Arrays are automatically expanded. For each array, a tag is created for the entire array as well as each index in the array.
- Tags cannot be created for User Data Types or Strings placed in the InOut section of a function block.
- User-defined types in tag tables cannot be expanded. The address of the start of the UDT will be provided as a tag.
