Note 1. With CS-series PLCs, I/O is allocated to B7A Interface Units (C200H
Group-2 High-density I/O Units) just like other Basic I/O Units (allocating
outputs first and then inputs for I/O Units). The unit number setting on the
front panel of the B7A Interface Unit does not affect I/O allocations.

2. B7A Link Terminals with 10 points or those with 8 input and 8 output points
cannot be connected to the B7A Interface Units. B7A Link Terminals with
16 points, two circuits of 16 points each (32 points total) or 16 points of
mixed I/O can be connected.
Only 16-point B7A Link Terminals can be connected to a B7A Interface Unit.
These are listed in the following tables.
