All analog I/O modules have 2 byte extendable parameterisation information,
which serves for the identification on the internal bus and the structure of the
mapping table.

With analog inputs 2 bytes follow which are reserved for future options. Mod-
ules with diagnosis capability allow the diagnosis message to be suppressed or
released channel for channel.

Analog outputs contain 4 byte parameterisation data. In this case the substitute
values are saved for a maximum of 2 channels (2 words).
