Both the input and output objects are mapped to the input and output PDOs in physical sequence.
This cannot be changed. In most masters, however, alias names can be assigned to the data, making
it possible for users to select any desired names for the data.
After the PLC configuration, the output bytes are assigned as shown in Table 10.
