Addressing Modes for Your Remote I/O

Identifying I/O Groups
You identify your I/O groups in one of three ways, depending on the
addressing method and I/O chassis you use. Refer to Figure 3.13 for
1-slot addressing when using series B I/O chassis.

Rules for module terminal point assignments are:
Standard density discrete I/O module in the left slot
has terminals numbered 00Ć07. (Mark top only.)
High density (16Ćpoint) discrete I/O module in either slot
has terminals numbered 00Ć07 and 10Ć17.
