1. Introduction
The CC-Link interface block FX2N-32CCL is an interface block which connects the FX0N/FX2N/FX
2NC
PC to
the CC-Link.
1.1 Outline of product
Applicable PC
The FX
2N
-32CCL can be connected as a special extension block of the FX0N/FX2N/FX
2NC
Series micro PC.
Control instruction
The buffer memory of the FX
2N
-32CCL is read and written by FROM/TO instructions.
Connection to CC-Link
The FX
2N
-32CCL is connected as a remote device station to the CC-Link system.
Shielded twisted pair cables are used for wiring.
Number of I/O points
Eight I/O points (including input and output) are occupied in the FX PC.
However, the capacity of the 5 V DC power supplied from the PC is limited.
The current consumption of 5 V DC in the FX
2N
-32CCL is 130 mA. Make sure that the total current consump-
tion of 5 V DC including other special blocks does not exceed the criteria.
Station No. and number of stations
Station No. : 1 to 64 (rotary switch)
Number of stations: 1 to 4 (rotary switch)

Transmission speed
Transmission distance
10 Mbps : 100 m
5 Mbps : 150 m
2.5 Mbps : 200 m
625 kbps : 600 m
156 kbps : 1,200 m
Detailed specifications conform to the CC-Link system common specifications.
Number of remote points
The number of remote I/O points in one station is 32 input points and 32 output points . However, the upper 16
points of the final station are occupied by the CC-Link system as the system area.
The number of remote registers in one station is 4 points of RW write area and 4 points of RW read area.
Because the number of stations can be selected within the range of 1 to 4, the system can be constructed in
accordance with the control size.

1.2 Connection to CC-Link
The FX PC connected with the inter face block FX2N-32CCL functions as a remote device station in the CCLink system.
One to four FX
2N
-32CCL units can be used at a time, and station Nos. not assigned to these FX2N-32CCL
units should be assigned to other remote device stations, remote I/O stations and local stations.
The number of connectable units, the transmission speed, the transmission distance, etc. conform to the CCLink system common specifications.

Cautions on design
• For the status of each station in the case in which the PC CPU stops its operation or communication error has occurred in the data link, read thoroughly the contents of "5.
Data Link Processing Time" of the user manual of the master unit.
Construct an interlock circuit in a PC program so that the system can operate conservativ ely using
the communication status information (SB, SW).
If the interlock circuit is not correctly constructed, wrong output or malfunction may occur, and an
accident may occur at the end.
- Receive data from the master station or a local station in which a data link error has occurred
1 ) Remote input (RX), remote output (RY)
The data varies depending on setting of the condition set switch on the unit and setting of the
input data (SW4) in a station in which a data link error has occurred.OFF: Data is cleared (All
OFF).
ON: The data just before an error occurred is held.
2 ) Remote register (RWw, RWr), remote input (RX), remote output (RY)
The data just before an error occurred is held without regard to setting of the SW4.
• Never bind the communication cable together with the main circuit, the power cable, etc. Never
locate the communication cable near the main circuit, the power cable, etc.
Keep the communication cable by 100 mm or more from the main circuit, the power cable, etc. If
this distance is not kept, malfunction may occur due to noise.
