* 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 2 slot addressing with
8 point 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 1 slot and 1/2 slot addressing with 16 point and
32 point 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.
