The offset for the input data for any rack and the I/O group can
be found from:
offset = 8 * (rack - 1) + I/O group + 2
where the rack number is in decimal
The offset for the output data for any rack and the I/O group
can be found from:
offset = 8 * (rack - 1) + I/O group
where the rack number is in decimal
