3.1.8.2 Analog I/O Modules
All analog I/O modules have 2 bytes of extendable configuration information,
which serves for identification on internal bus and the formation of a mapping
table.
Analog inputs are followed by 2 bytes reserved for future options. The
diagnostics message can be suppressed or released for each individual channel
by means of modules capable of diagnostics.
Analog outputs have 2 byte configuration data for each channel. These are
used to save the substitute values for corresponding channel.
