8.6.4 Mapping of digital values
As an alternative to bit-wise mapping of digital values to PDOs, you can also use object 0x6000
for mapping digital values.

Mapping of digital values
Displaying digital values
The SDO shows the value I_DIGITAL for selected values. If you have not previously configured
the corresponding port for digital values, then no error message is issued and the value in this bit
is not defined.
Enabling byte-wise mapping
To switch from the default bitwise mapping to the bytewise mapping after system startup, two
SDO commands must be sent to the node:
