PLC – MELSEC FX3UC
High-End and Ultra-Compact
The new MELSEC FX3UC CPU brings greater flexibility and
more performance to applications which do not have space
for traditional style PLC's. Like all other members of the
FX family, each FX3UC PLC consists of a fully-integrated
base unit that contains all the necessary PLC components,
from the CPU to memory and the I/O controller.
The smallest base unit with 8 digital inputs and 8
transistor outputs takes up just 27 % of the space
required for a comparable FX3U unit – and yet the FX3UC
incorporates all the features of the FX3U.
The FX3UC base units all have a 24V DC power supply and
are available in versions with 16, 32, 64 or 96 I/Os. They
can be expanded up to a maximum configuration of 384 I/Os
by adding expansion modules and networked I/O points.
Just like the FX3U, the FX3UC offers outstanding
connectivity for all standard networks.
I/O terminal blocks with screw or spring terminals can be
connected with standard ribbon cable connectors.
Are you looking for a control solution with power to
spare? Then the FX3UC may be what you are looking for
- an execution cycle period of just 0.065 ms per logical
- up to 40,768 data registers
- up to 7,680 internal relay coils/flexs
- 210 commands
- memory for up to 64 k of PLC program steps
This makes the FX3UC one of the fastest and most powerful
PLC systems in its class. In fact, it puts quite a few
larger modular controller systems in the shade.

PLC, Reliable control when you need it most
The modular concept
Building on its predecessor, the AnSH, SystemQ is a
control concept that allows users to mix and select the
best combination of CPUs, communication devices,
specialist control modules and discreet I/O on a
This allows users to configure systems into what they
need, when they need it, where they need it.
Basic and advanced PLC CPUs, specialist motion and
process controllers and even PCs can be combined into a
single SystemQ solution with up to four different CPUs.
This gives users a choice of control philosophies,
programming concepts and programming languages – all from
a single platform.
An automation platform for the future
Flexibility and scalability are key design features that
enable System Q to truly be a single Automation Platform.
Users can apply simple control to an individual machine or
integrated plant wide management all from the same
What can you expect from Mitsubishi Modular PLCs?
- Global use
A wide range power supply means your Modular System Q
will work all over the world and with the huge range of
shipping approvals, CE compliance, as well as
manufacturing to Automotive industry quality levels,
SystemQ is a product to trust.
- Totally scalable
System Q is designed to grow with your application, from
the Q00J standalone solution to the networked and
redundant process CPU Q25PRH. System Q's platform
concept allows you to add and customize the special
functions you need.
- Multi CPU
The SystemQ Automation Platform allows you to use
multiple CPU’s on a single backplane. You can combine up
to four CPU types, such as PLC, Motion, PC, Q-C and
Process CPU’s, as a single seamless solution.
- Multi network connectivity
From basic AS-Interface to Ethernet based networks,
System Q can communicate easily with Mitsubishi or third
party products. To increase the productivity in your
plant, System Q can also provide a direct connection to
any database based on SQL via an Ethernet connection.
The wide range of power supplies, CPU’s, I/O Modules,
Special Modules and Communication Modules makes System Q
one of the most flexible modular automation systems in
- Dual redundancy
The redundant Process CPUs Q12/25PRH can, with standard
PLC technology, provide a hot standby system with the
automatic synchronization of data. The modular concept
also allows different degrees of redundancy from power
supply and control systems to redundant network modules.

PLC – process control
Process control you can count on
A platform to build on
The strength of System Q’s automation platform really
comes into its own in traditional specialist industries.
The unique flexibility of proven off-the-shelf control
components such as I/O and communication devices, teamed
with dedicated special devices like process CPUs, assures
high functionality, ease of use and targeted control – all
Two worlds meet
Our dedicated System Q process CPUs build on the already
high functionality of Mitsubishi’s advanced PLC CPUs. This
powerful combination of sequential control overlaid with
dedicated process instructions gives users a hybrid
control solution with the best of both worlds.
This is complemented in turn by a range of dedicated
channel-isolated and highresolution analogue modules.
Here, too, a combination of specialist and standard
modules provides the basis for practical and flexible
High system availability can be maintained through
various means, including redundant process CPUs, stand-by
network masters, and redundant network configurations, as
well as by wire-break detection and a “hot-swap”
capability that allows modules to be replaced during live
Programming can be implemented using a wide range of
tools such as IEC1131.3 compliant software and the
process-dedicated PX Developer.
System Q’s Process CPUs bring the benefits of standard
System Q technology into the process environment, reducing
both implementation and long-term running costs. These
powerful processors combine standard PLC control with 52
dedicated process control functions, including loop
controls with two degrees of freedom (DOF) and highspeed
Mitsubishi Electric’s dual-redundant CPUs bring an
additional layer of fault tolerance to the control of a
whole system. This results in high reliability: if the
main CPU, power supply or base unit fails, a secondary
system starts immediately (within 21ms) from the same
For users this has two major benefits: no operational
damage due to a single system failure, and production that
High reliability systems
The System Q automation platform can also be applied to
other areas requiring high reliability, e.g. standby
network masters, redundant fieldbus (CC-Link) and
redundant power supplies for remote I/O stations.
In addition, selected analogue and temperature control
units have a wirebreak detection feature enabling them to
determine the difference between an actual signal and one
that has been lost due to external system damage.
