Up to 3 units can be sequentially connected to the end of a system.
However, when three units are connected, they are counted as a unit, and the number of input/output
occupied points is 8.

When more than one master station is connected, a remote I/O station cannot be connected to the 2nd and
following master stations.

-16CCL-M.
Only one station can be used for the whole system.
4. Calculate the total number of input/output points.
Total the number of points counted in Steps 1, 2 and 3, and check that it does not exceed 256 points
(maximum number of input/output points).
5. When CC-Link or AS-i master is used, count the remote I/O points.
In the case of the FX
3UC
-32MT-LT Ver.2.20 or later or FX

- MT/D, DSS
When a CC-Link or AS-i master is used, the total number of input/output points of the remote I/O stations
connected on the network and the number of input/output points calculated in the previous step must be 384
or less.
For details, refer to the following subsection.
