5.4.3 Digital Special Modules
All special digital modules have 2 bytes of extended parameterization
information, which serves for the identification on internal bus and the
structure of the mapping table.
Input modules (counter) are followed by 2 bytes, which are reserved for future
options.
Output modules (PWM outputs) are followed by 6 bytes of parameterization
data, which serve for the saving of substitute values for a maximum of 2
channels (2 words).
