The second transmit PDO (TxPDO2) is provided by default for analog 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 analog inputs are organised in words, 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).
