USAGE:
EXAMPLES:
This program was designed to read four analog inputs from 2 analog input cards (the first two cards) in
the rack of a Wago I/O system. Note Modbus function 3 is used to read the four regsiters starting at
register 0 (The E & R variables.) Register 0 correlates to Modbus address 40000. The data received is a
binary value that reporesents a +/- 10 volt input, thus the conversion calculation.
