The 3 to 16 receive PDOs (RxPDO3ff) are automatically given a default mapping by the bus node
depending on the attached terminals (or depending on the extension modules). The procedure is described
in the section on PDO Mapping [} 63].
A specific sequence must be observed in order to change the mapping (see object index 0x1600).
NoteDS401 V2 specifies analog input and/or output data as the default mapping for PDOs 3+4. This
corresponds to Beckhoff's default mapping when less than 65 digital inputs or outputs are present.
In order to ensure backwards compatibility, the Beckhoff default mapping is retained - the mapping
behaviour of the devices therefore corresponds to DS401 V1, where in all other respects they ac-
cord with DS401 V2.
