The FX5UJ series complement the MELSEC iQ-F

The first step towards IoT with the integrated functions of the FX5UJ

Compact and cost-efficient performance miracles!

The FX5UJ compact PLC series offers outstanding performance and is perfect for a wide range of applications thanks to its flexible usage options.

Many proven, integrated functions of the FX5U series are also included in the FX5UJ series for even greater user convenience. The multi-protocol Ethernet port (CC-Link IE Field Basic, Modbus TCP/IP, SLMP, etc.) enables communication via up to eight network connections and supports simultaneous connection to PCs and other devices. In addition, the Ethernet port can be used for direct SLMP communication with the higher level.

Like the FX5U series, the FX5UJ series can also be expanded on both sides to up to 256 I/Os using the familiar FX5 expansion modules.

The intelligent functions of the MELSEC FX5UJ

The FX5UJ series combines outstanding performance with flexible application options. It builds on the proven features of the FX5U series and offers user-friendly expandability and modern communication options. With integrated Ethernet, USB connectivity and security features, the FX5UJ ensures efficient control and reliable protection. Thanks to maintenance-free flash ROM technology, there is no need for batteries, which increases long-term reliability.

High-speed counter function

The input device assignment for the high-speed counter is carried out via the parameterization of the channels. The process is carried out with the HIOEN command.

Positioning function

A pulse output of up to 200 kpps with support for 3 axes is possible, equipped with transistor outputs.

Data logging function

Simple data acquisition without programming is enabled, with logging data output in CSV or binary format to support troubleshooting, analysis and traceability.

Memory dump function

In the event of an error, device values are automatically saved as a batch on an SD card and can be viewed directly in the program editor, which speeds up error analysis and rectification.

PLC with communication and control interfaces

With the FX5UJ, you get a versatile and user-friendly control unit that is ideal for modern applications. It is equipped with various interfaces that enable simple and flexible integration into existing systems.

✔ Built-in Ethernet connection
The Ethernet port supports communication with up to eight devices on the network, allowing easy connection to computers and other devices. In addition, it supports seamless SLMP communication with higher level devices.

✔ USB connection (Mini-B)
Equipped with a standard USB port (Mini-B), the PLC facilitates connection to engineering tools and ensures quick and uncomplicated configuration.

✔ RUN/STOP/RESET switch
The RUN/STOP/RESET switch makes it possible to restart the system efficiently without having to switch off the power supply. This is particularly useful for troubleshooting and for quickly restoring operational readiness.

✔ Function extension
The slot for function expansions allows the main unit to be expanded with additional serial interfaces. In addition, the SD card required for the web server functionality can be inserted here, which can also be used to temporarily store log data.

Open industrial Ethernet technology

Thanks to its compatibility with CC-Link IE Field Basic, an open industrial Ethernet technology, the controller can be easily connected to other devices such as HMIs, drives and remote I/Os. This ensures reliable communication and makes it easier to set up networked production areas.

Communication with PLCs from other manufacturers is also possible without programming

Communication with PLCs from other manufacturers is possible without programming - both with PLCs from Mitsubishi Electric and with those that support the “Simple CPU Communication” function.

Thanks to the simple parameter setting, PLC data can be recorded, making it much easier to set up a retrofit system.
