1.14.1 Judgment of availability after reexamination of configuration

In this configuration, it is necessary to add an extension power supply unit FX
restrictions in the 5V DC power supply capacity and the restriction in the number of connectable units.
Construct the system as follows.
1. Example of reexamined system configuration

2. Reexamination of system configuration availability
1) Restriction for the number of input/output points
There is no problem since the number of input/output points in the new system is "208".
2) Restriction for the 5V DC power supply capacity
The 5V DC power supply capacity is as follows after countermeasures.

"a)Supplier side" - "b)Consumer side" = 350mA - 265mA = 85mA
There is no problem since the total current consumption is less than the
capacity "350mA" supplied by the main unit.
