Connect to serial devices up to 50 m away with built-in RS-485
port. Control for up to 16 Mitsubishi inverters is possible with
dedicated inverter communication instructions. MODBUS is also
supported and can connect up to 32 MODBUS devices such as
PLCs, sensors and temperature controllers.
High-speed system bus communication at 1.5 K
words/ms (approximately 150 times faster compared
with FX3U), together with high speed CPU, allows
MELSEC iQ-F to output maximum performance even
when heavy data communication intelligent function
modules are used.
MELSEC iQ-F is powered by a high speed CPU that
can execute the LD instruction in 34 ns.
Furthermore, MELSEC iQ-F can execute structured
programs, execute multiple programs and handle
ST language and function blocks.
RUN/STOP/RESET switch is built in.
PLC can be rebooted without turning off the main power for
efficient debugging.
MELSEC iQ-F has advanced security functions (file password,
remote password, security key) to prevent data theft and illegal
operations by unauthorized persons.
MELSEC iQ-F series holds
programs and devices in
nonvolatile memory such as
flash ROM, and does not
require a battery.
Ú
It is possible to increase the capacity of
held devices by using an optional battery.
FX5U is equipped with 12-bit 2ch analog input and 1ch analog output.
With parameter setup, no programming is required.
Value shifting, scaling and alarm output can also be set easily with parameters.
A built-in SD memory card slot
is convenient for updating the
program and mass production
of equipment. Data can be
logged in SD memory card
(future support), making it easy
to analyze the system status
and production state, etc.

Built-in Ethernet Port
The Ethernet communication port can handle communication of up to
8 connections on the network, and can support multiple connections
with personal computer and other devices. In addition, the Ethernet
communication port can handle seamless SLMP communication with
the upper-level device.
The CPU module and engineering tool (GX Works3)
can be directly connected with a single Ethernet cable.
