Follow these guidelines when you select 2-slot addressing:
• Place an 8-point output module opposite a 16-point input module.
• An I/O group having a 16-point input and output module cannot
have a corresponding I/O group in the complementary chassis.
• You can place an output module opposite another output module;
they reflect the same bits in the output image table.
You can use block-transfer modules in a complementary I/O system,
with these restrictions:
