Link and Communication
FX
3U
/FX
3UC
PLCs support the following communication functions:
1. CC-Link
The CC-Link system can be constructed with an
FX
3U
/FX
3UC
PLC working as the master station.
Or an A or QnA PLC can work as the master
station, and FX PLCs can be connected as slave
stations (remote device stations).
The CC-Link is an open network allowing
connection of not only FX PLCs but also
inverters, AC servo systems, and sensors.
→
Refer to each manual packed together.
2. CC-Link/LT
The CC-Link/LT system can be constructed with
an FX
3U
/FX
3UC
PLC working as the master
station.
General X (input) and Y (output) devices are
assigned to remote I/O units, and operated by
programs for general-purpose I/O.

Refer to the FX
3UC
Hardware Manual for
the built-in type CC-Link/LT master.

3. MELSEC I/O LINK
The MELSEC I/O LINK is a remote I/O system
whose master station is an FX
3U
/FX
3UC
PLC.
Units for MELSEC I/O LINK remote I/O system
(A PLCs) can be used as remote units.

Refer to each manual packed together.
4. AS-i system
A network system at the actuator or sensor level
can be constructed with an FX
3U
/FX
3UC
PLC
working as the master station in the AS-i system.
→
Refer to each manual packed together.
5. Simple N : N link
Up to eight FX
3U
/FX
3UC
PLCs are connected,
and data are automatically transferred among
them.
→
Refer to the Data Communication Edition.
6. Parallel link
Two PLCs are connected, and data are
automatically transferred between them.
→
Refer to the Data Communication Edition.
7. Computer link
A computer such as personal computer works as
the master station, up to sixteen FX and A PLCs
are connected to the master station, the master
station directly specifies devices in the PLCs,
and then data are transferred.
Protocols in the computer link support the
formats 1 and 4.
By using MX Component and MX Sheet,
monitoring and logging for the PLC system can
be easily set by Microsoft Excel.
→
Refer to the Data Communication Edition.
