Communication function

CC-Link

CC-Link is an open network enabling connection of various FA equipment.
We prepare a master unit setting FX PLC as master blocks of CC-Link, as well as an interface setting them as remote device stations of CC-Link.

Details

CC-Link/LT

CC-Link/LT is an open network in the open network CC-Link family designed to reduce wiring in the cabinet and the machine.
Also, FX3UC-32MT-LT(-2) has CC-Link/LT master functionality built-in, so reduced wiring network can be easily achieved.

Details

N:N network

This network connects multiple FX PLCs (maximum 8 units) and performs automatic data exchange between each PLC. Linked devices are exchanged between each PLC, and all connected PLCs can share (monitor) linked devices.

Details

Parallel Link

Bit devices (M) and word devices (D) automatically refresh.

Details

Computer Link

A computer as master can connect to FX series as slave.
Supports "computer link protocol formats 1 and 4" on the computer side.

Details

Non-Protocol Communication

Non-proocol serial communication is possible to devices with RS-232C or RS-485 (422) communication interface (PC, barcode reader, etc).

Details

Peripheral device communication

PC, GOT, and HPP can connect to RS-232C/RS-422/USB (USB can be used by PC only) and perform PLC program transfer and monitoring.

Details

inverter communication

Mitsubishi inverter prococol and dedicated instructions for communication control are built into FX3 series PLC. Mitsubishi inverters can be easily controlled just by adding an RS-485 communication device.
