the reader, set this using the "CM_CHANNEL" parameter. The "HW_ID" and "LADDR"
parameters remain the same for all channels/readers.
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 and configuring the blocks.
Note
Configuring "IID_CMD_STRUCT"
If you work with the Ident profile or with the "AdvancedCmd" block, you also need to create a
