32-Point I/O Modules
To use 32-point I/O modules with 1-slot addressing, you must install, as a
pair, an input module and an output module in two adjacent slots (even/odd
pair) of the I/O chassis, beginning with I/O slot 0. If you cannot pair the
modules in this way, one of the two slots of the pair must be empty. For
example, if I/O slot 0 holds a 32-point input module, I/O slot 1 must hold
an 8-, 16-, or 32-point output module (or a module using the backplane for
power only); otherwise the slot must be empty.
