2.4 Link and Communication
FX3G/FX3U/FX3UC PLCs support the following communication functions:
1. CC-Link
The CC-Link system can be constructed with an
FX3G/FX3U/FX3UC PLC working as the master
station.
An A or QnA PLC can work as the master station,
and FX PLCs can be connected as remote device
stations.
A Q PLC can work as the master station, and FX
PLCs can be connected to remote device stations or
intelligent 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 the included manual.
2. CC-Link/LT
The CC-Link/LT system can be constructed with an
FX3G/FX3U/FX3UC 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 FX3UC Hardware Edition for the
built-in type CC-Link/LT master.
Refer to the product manual for the
FX2N-64CL-M.
3. MELSEC I/O LINK
The MELSEC I/O LINK is a remote I/O system
whose master station is an FX3U/FX3UC (D, DSS)
PLC.
Units for MELSEC I/O LINK remote I/O system (A
PLCs) can be used as remote units.
Refer to the included manual.
4. AS-i system
A network system at the actuator or sensor level can
be constructed with an FX3U/FX3UC PLC working as
the master station in the AS-i system.
Refer to the included manual.
5. Simple N : N link
Up to eight FX3G/FX3U/FX3UC PLCs are connected,
and data is automatically transferred among them.
Refer to the Data Communication Edition.
6. Parallel link
Two PLCs are connected, and data is 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
is transferred.
Protocols in the computer link support the formats 1
and formats 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.
For MX Component and MX Sheet, refer to the
respective product manual.
8. No-protocol communication
No-protocol serial communication is available
between an FX PLC and interface equipment in
accordance with RS-232C/RS-485 such as bar code
reader, printer, personal computer and measuring
instrument.
Refer to the Data Communication Edition.
9. Inverter communication
An FX PLC can control up to eight inverters via
communication in accordance with RS-485.
