The first transmit PDO (TxPDO1) is provided by default for digital input data. Depending on the number of
inputs inserted, the necessary length of the PDO is automatically determined, and the corresponding objects
are mapped. Since the digital inputs are organised in bytes, the length of the PDO in bytes can be found
directly at sub-index 0.
A specific sequence must be observed in order to change the mapping (see object index 0x1600).
