Note 1. Do not connect Terminals with different transmission delays to the same Interface Unit. Doing so will
cause a transmission error.
2. The 10-point B7A Link Terminals and mixed-I/O B7A Link Terminals with 8 inputs and 8 outputs cannot
be connected to B7A Interface Units. Use 16-point B7A Link Terminals. The 16-point B7A Link Terminals
include 16-point (non-mixed) Terminals, 32-point Terminals configured with two 16-point circuits, and
mixed-I/O Terminals with 16 inputs and 16 outputs.

Note 1. Mount the C200H-B7AO1 B7A Interface Unit to the C200H-BCjj1-V1 or C200H-BCjj1-V2 Back-
plane.

be connected to B7A Interface Units. The 16-point (non-mixed) Terminals, 32-point Terminals config-
ured with the two 16-point circuits, and mixed-I/O Terminals with 16 inputs and 16 outputs can be con-
nected.
