The library is now linked in and the required blocks and data types have been created in
your project. The "IID_HW_CONNECT" data type has also been created and addressed.
You can now start programming the blocks.
Note
Configure "IID_CMD_STRUCT"
If you work with the Ident profile or with the "AdvancedCmd" block, you also need to create a
further element with the data type "I
ID_CMD_STRUCT" (Array [1...n]) in the data block you
have already created.
