The 3 to 16 transmit PDOs (TxPDO3ff) 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
behavior of the devices therefore corresponds to DS401 V1, where in all other respects they accord
with DS401 V2.
For the sake of completeness, the following object entries are also contained in the object directory (and
therefore also in the EDS files):
