Additional notes for FB-TcIoXPlanarTile

The different structure of the AP4322 and APS42xx tiles requires different access to the respective TcCOM parameters. The FB_TcIoXPlanarTile function block is divided into a section for APS4322 and a section for APS42xx, in which the corresponding interfaces are implemented.

A significant difference between the APS4322 and APS42xx tiles is that the APS42xx tile can have up to three sub-tiles: FB_TcIoXPlanarSubTile. The APS4322 tile, on the other hand, has the FB_Aps4322Drive function block to manage the CoE parameters.

To avoid communication errors, Beckhoff recommends not performing CoE communication with the APS42xx tiles.
