The module always expects two words of user defined data, even if the data is not
used. The first word of the user shutdown field is used for channel 1, the second for
channel 2.
Word 6
Discrete Output Register
This word contains a right justified binary eight bit data field.
Words 7 ... 8
Map to Analog Output Register
Each word in this range contains a left justified binary 15 bit data field. The range is
0 ... 7FFE hex (0 ... 32766 decimal), but the resolution is only 14 bit.
