* Conditional module placement: you must use an input module and an output

module in two adjacent slots of the I/O chassis beginning with slot 0.

IMPORTANT: Series A I/O chassis let you use 2Ćslot addressing with 8Ćpoint

I/O modules only, regardless of the type of adapter module you use. This chart

is valid for series B I/O chassis. You need series B I/O chassis to achieve 1Ćslot

and 1/2Ćslot addressing with 16Ćpoint and 32Ćpoint I/O modules.

In this chapter we discussed how to address your hardware and the
various remote I/O configurations and options you can use in your
remote system.
