4.8 PDO mapping
PDO mapping refers to the mapping of application objects (real-time data, e.g. object
6064h "Actual Position" from the object dictionary into Process Data Objects, e.g.
Object 1A00h (1st Transmit PDO).
The current mapping can be read via corresponding entries in the object dictionary,
the so-called mapping tables. The number of mapped objects that are listed
subsequently is found at the top of the mapping table (subindex 0). The tables are
located in the object dictionary in index 0x1600 ff. for the RxPDOs and 0x1A00ff for
the TxPDOs.
