1. Outline
1.1 Product Outline
The CC-Link/LT master block FX2N-64CL-M can be connected to the FX Series PLC.
The CC-Link/LT system can be constructed with an FX Series PLC as the master station.
1.2 Features
The FX2N-64CL-M has the following features:
1) Reduced wiring time
Using CC-Link/LT connection cables and connectors allow for reduced wiring times.
(Dedicated flat cables, VCTF cables and high flexible cables are available.)
2) Simplified programs
Link devices within CC-Link/LT are assigned to X/Y devices in the PLC, therefore, sequence
programs can be prepared without recognizing the network.
3) High speed refresh
High speed refresh (128 points/0.3 ms) is realized (as and when the transmission speed is
2.5 Mbps, 16-point mode is selected and eight stations are connected to the network).
4) Slave station disconnection function
Even if some units are down due to an abnormality, communication with the remaining
functional units is not affected.
When a cable in the trunk line is disconnected, however, the data link is disabled for remote
stations connected to the disconnected cable.
5) Automatic return function
When a unit that was disconnected due to an abnormality is restored to it’s normal status,
the unit will return to the data link automatically and continue data transfer.
6) Data link stop/re-start
While data link is being executed, the user can stop and start the link again.
7) Remote station type information storage
In the CONFIG mode, the number of points occupied by remote stations, I/O types, etc. is
detected, and stored within the EEPROM.
8) Mode selection
The ONLINE, CONFIG and TEST modes are available.
ONLINE mode : Executes the data link for the CC-Link/LT system.
Select the ONLINE mode usually.
CONFIG mode: Allows automatic assignment of the I/O number.
When remote stations are planned to be added in the future, reserved
stations can be specified and detailed remote station information can be
edited.
After constructing the CC-Link/LT system, make sure to execute the
CONFIG mode once to assign the I/O number.
TEST mode : Executes self-diagnosis to judge whether the FX2N-64CL-M itself is in the
master station.
If the data link cannot be executed normally, the self-diagnosis function
analyses the FX2N-64CL-M itself.

• Factory default, DIP switches are set OFF.
• The Test mode is selected when both the CONFIG and TEST modes are set ON
simultaneously.
• For each setting, the status at the time of power ON is valid.
(If a setting is changed after the power is set ON, such a change is invalid.)
• In the CONFIG mode, the L ERR. indicator lights or flickers when the detailed information
on the remote station actually connected at the time of power ON do not match the detailed
remote station information within the master.
(When BFM #32 (20h) to #95 (5Fh) are edited, the station numbers are checked.)
If the remote station information is not edited, the L ERR. does not light or flicker when

2. Specifications
This section explains the specifications of the FX2N-64CL-M.
DESIGN PRECAUTIONS
When a remote module fails, outputs may randomly set ON or OFF, therefore, build an
external monitoring circuit that will monitor any input signals that could cause a serious
accident.
DESIGN PRECAUTIONS
• Do not bind control and connection cables to CC-Link/LT together with power cables.
Keep control and connection cables to CC-Link/LT away from major circuits and power
cables by 100 mm (3.93") or more.
It may cause a malfunction due to noise interference.
• Use the FX2N-64CL-M in such status that any force is not applied on connectors for CC-
Link/LT interface and connection cables to CC-Link/LT.
If any force is applied, wire breakage and failure may be caused.
STARTING AND MAINTENANCE PRECAUTIONS
• Do not touch the terminals while the power is ON. It may cause an electric shock or
malfunction.
• Shut down all phases of the power supply outside the master block before starting any
cleaning procedures.
If the power is not disconnected from all sources, the FX2N-64CL-M may fail or
malfunction.
STARTING AND MAINTENANCE PRECAUTIONS
• Do not disassemble or modify the FX2N-64CL-M.
Doing so may cause failure, malfunction, injury, or fire.
• The case of the FX2N-64CL-M is made of resin.
Do not drop or apply strong impacts to the FX2N-64CL-M.
DISPOSAL PRECAUTIONS
• Treat the FX2N-64CL-M as industrial waste when disposing of the product.
