2.4 Link and Communication
FX3G/FX3U/FX3GC/FX3UC PLCs support the following communication functions:
1. CC-Link
The CC-Link system can be constructed with an
FX3G/FX3U/FX3GC/FX3UC PLCs 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/FX3GC/FX3UC PLCs 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 Edition for the
built-in type CC-Link/LT master.
→ Refer to the product manual for the
FX
2N-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, DS,
DSS) PLCs.
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 PLCs working as
the master station in the AS-i system.
→ Refer to the included manual.
5. N : N Network
Up to eight FX3G/FX3U/FX3GC/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 PLC, 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
Excel
®
.
→ Refer to the Data Communication Edition.
→ For MX Component and MX Sheet, refer to the
respective product manual.
8. Non-protocol communication
Non-protocol serial communication is available
between an FX PLCs 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 PLCs can control up to eight inverters via
communication in accordance with RS-485.
