Addressing I/Os on Expansion Modules
Inputs and outputs located on I/O expansion modules are assigned addresses
that comprise a letter and a number. The letter indicates whether the I/O is
an input (I) or an output (O). The number indicates the actual physical
location of the I/O. This number relates to both the position of the expansion
module in the system, and to the position of the I/O on that module.
Expansion modules are numbered from 0-7 as shown in the figure below.
