1.13.1 Re-examination of suitability for configuration
In this configuration, it is necessary to add the extension power supply unit FX3UC-1PS-5V due to the
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 FX3UC-1PS-5V between the FX2NC-16EYR-T and the FX2NC-16EYR-
T.
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
- Extension power supply unit side
