4.1 Reading Discrete Inputs
Each word address consists of 16 bits. These bits can be read as discrete inputs.
Word address 40001 corresponds to discrete inputs 10001 to 10016. 40002
corresponds to discrete inputs 10017 to 10032.
((Address - 40001) X 16) + 10001 This will give you Input address 0 of the
word.
