1.13.1 Re-examination of suitability for configuration

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

2. Reexamination of system configuration availability
1) Restriction in 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 the countermeasures.
- Main unit side
a)Supplier side
FX -32MT-LT 350mA
3UC
b)Consumer side
FX -32EX

"a)Supplier side" - "b)Consumer side" = 350mA - 270mA = 80mA
There is no problem since the total current consumption is less than the
capacity "350mA" supplied by the main unit.

"a)Supplier side" - "b)Consumer side" = 1000mA - 470mA = 530mA
There is no problem since the total current consumption is less than the
capacity "1A (1000mA)" supplied by the extension power supply unit.
