User’s Manual - Hardware Edition
9.3.2 Number of connectable additional CC-Link/LT masters
The FX3UC-32MT-LT can connect not only one CC-Link/LT built-in master but also up to 7 additional CC-
Link/LT masters (FX
2N-64CL-M) including special function units/blocks.
However, only up to 256 I/O points can be controlled.
1. Additional CC-Link/LT master connection method
Connect the extension power supply unit or FX2NC-CNV-IF on the right side of the PLC main unit, and then
connect the extension cable of the additional CC-Link/LT master (FX
2N-64CL-M) to the extension connector
for FX
0N/FX2N.
→ For details, refer to Chapter 3.
2. Number of input/output occupied points and restriction in number of input/output points
The number of input/output occupied points of the additional CC-Link/LT master is "8 (either input or output) +
Number of input/output points in connected remote stations".
Make sure that the total number of input/output points including extension units does not exceed 256.
→ For details, refer to "Section 1.6 System overall configuration".
3. Restriction in current consumption from 5V DC power supply in PLC
The additional CC-Link/LT master (FX2N-64CL-M) consumes 190mA from the 5V DC power supply.
Make sure that the total current consumption from the 5V DC power supply of I/O extension blocks and
special function units/blocks connected to the PLC main unit does not exceed the 5V DC power capacity of
the main unit and extension power supply unit.
→ For details, refer to "Section 1.6 System overall configuration".
