3) Restriction for the number of connectable units
a) Expansion board
There is no problem since this configuration includes only 1 expansion board.
b) Special adapter
There is no problem since this configuration includes only 1 special communication
adapter and 1 special analog adapter.
c) Special function unit/block
This configuration includes the following 3 special function units/blocks.
There is no problem since up to 7 special function units/blocks can be connected.

d) Other restrictions
In some models, only 1 unit can be connected to the main unit. When connecting 2 or more units, it is
necessary to add an extension power supply unit. (Refer to Subsection 1.10.2.)
This configuration includes the following equipment, which falls under the restriction for
the number of connectable units.
