The difference between Mitsubishi FX3u and FX5u

Mitsubishi FX3U series PLC is the third generation of miniature programmable manipulators, using a type of programmable memory, which is used to store programs internally, execute user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input/output. The Mitsubishi FX5U series PLC is also a Mitsubishi compact PLC, with the improvement of basic performance, the connection with the drive product, and the improvement of the software environment as the highlights, as an upgrade of the FX3U series, the FX5U series came out in 2015.

The difference between Mitsubishi FX3u and FX5u

Differences between Mitsubishi FX3u and FX5u:

1. System bus speed: FX5U series as an upgraded version of fx3u, although small and precise, compared with FX3U, the system bus speed has indeed been greatly improved, increased by up to 150 times. It can expand up to 16 intelligent expansion modules, with built-in 2-in, 1-out analog function, built-in Ethernet interface and 4-axis 200kHz high-speed positioning function.

2. Programming software: Mitsubishi FX3U supports CC-LINK, which can be programmed with GXDeveloper and GXWorks2, but GXDeveloper 7.11 and below do not support Fx3U simulation, and the device is only capable of high versions, I have personally tried GXDeveloper 8.52 + Gx Simulator 7.16 can program simulation, as for other versions, you can give it a try. GXWorks2 comes with its own simulation software, no need for additional device simulation software, beginners can directly install GXWorks2, the device is simple and easy to use. The Mitsubishi FX5U supports CC-LINKIE, which can only be programmed with GXWork3, GXWORKS3 intuitive graphical operation of the programming software, and through the FB module, the development man-hours are reduced. The simple motion control positioning module is used to achieve rich motion control through SSCNETIII/N positioning control.

3. The biggest difference between the updated iteration FX3U and FX2N wiring is that 3U has an S/S end, and the PLC can be turned into a leaky input or source input through the S/S end, FX2N does not have this function, by the way, as early as 2012, Mitsubishi official website issued a notice of Mitsubishi FX2N discontinuation, repair the corresponding date, and only within 7 years, as an older generation model, it has been slowly withdrawn from the market, and now there are very few people who use it. The new generation of machines has Ethernet as the fundamental interface, which is faster. FX5U takes the improvement of fundamental performance, the connection with the driver product, and the improvement of the software environment as the highlights, and replaces FX3U in the market. Learn Mitsubishi FX series, FX2N, FX3u is no longer the main force, you should learn FX5U such a new generation of machines, as long as the old generation of products do the corresponding understanding, of course, you can also learn the older model, used to learn the basis of plc programming.

4. The program conversion FX3U/FX3UC program can be converted to FX5U series program, and the FX3U/FX3UC project can be replaced with the MELSEC iQ-F project by using GX Works3. After the replacement of the project, you need to check it, and you may need to replace some programs and parameters, and the program mostly refers to instructions and soft components.
