Outputs in the complementary chassis would use the same bits in the
output image table as the outputs in the primary chassis. You cannot
place inputs in the complementary chassis.
Example 1
Example 2
1 = Output modules use the same output image table bits. This is not recommended.
2 = Must be empty if corresponding primary slot is a block transfer module.
Important: With 2-slot addressing, if an input module resides in either slot associated with a
logical group of the primary chassis, an input module cannot reside in that logical group' s
complementary chassis.
