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