Connectable B7A Link Terminals
Only 16-point B7A Link Terminals can be connected to a B7A Interface Unit. These are listed in the following
tables.

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

Note In the case of Group-2 B7A Interface Units, words 030 to 049 (Group-2 High-density I/O Unit and B7A Inter-
face Unit Area) are allocated according to the setting of the I/O number setting switch on the front of the Unit
as shown in the following table. For mixed I/O Units, words are allocated in in the order output → input.
