Error status can be checked by reading address: 300011h.
Determine category by reading address:301000h.
For analog-type module, category is "02h".
Set analog input range.
Analog input range is written to address: 301013h.
Default is "00h" (Analog input range: -10V to +10V).
This value need not be written when the default is used.
Module is started by writing "01h" to address: 301010h.
When started, the module can get valid analog input data.
By reading 2 bytes from address: 304000h,
the module can get analog input data from CH0.
In subsequent operations, the module can get analog
input data with 2 bytes at a time, up to CH3.
