LE3U PLC is compatible with Mitsubishi GX-Developer/GX-WORK2 software and supports human-machine interface connection, making it equivalent to the Mitsubishi FX3U PLC.
It supports ladder programming, download, and monitoring, and uses a programming port for program download and communication with the human machine.
The LE3U PLC is designed with an industrial-grade 32-bit MCU, which has strong anti-interference capabilities and runs much faster than the FX3U PLC.
The transmission baud rate for the LE3U PLC is 38400.
- Support Mitsubishi GX-Develoer\GX-WORK2
- Support for human-machine interface connection, the application is completely equivalent to Mitsubishi FX3U
- Support ladder programming, download, and monitoring.
- The programming port used for program download and communication with the human machine
- This PLC adopts an industrial-grade 32-bit MCU with strong anti-interference, and its running speed far exceeds that of FX3U.
- This PLC transmission baud rate is 38400

Olá amigo PLC FX3U
Eu utilizo GX developer para programar só que esta acontecendo o seguinte
Não aparece para mim o transfer setup para que eu possa escolher a porta serial
você pode por gentileza me ajudar
re-install your software.
I want to read analog input on the first LE3u from the second LE3U using RD3A k1 k0 D1, can I need to rs485 physical port or protocol, what is other method, and how to connect wires to can be using the second LE3U board as a extension module. Please guide for me, sent guiding document to dhauto.ltd@gmail.com. thanks so much.

How to connect 2 PLCs using RS232 . communication ?
need use rs485
hola buenas tardes se puede comunicar por rs485 o rs232 con arduino como maestro y PLC LE3U como esclavo
the plc support modbus
Boa tarde como faço para atualizar a hora do clp fx3u, não consigo atualizar para criar uma função horária.
Power off . my fx3u-32mt device doesn’t remember the data. specifically from d200~d7999 will go to 0. is there any solution. battery ok
From D0 to D511, the default is not maintained when power off, and D511 is locked after power off by default.
Can we write 8 register from master PLC to slave using Modbus RTU in single command like IVWR.
check example Frequency converter 485 communication.zip
Good day!!! Are IVRD, IVWR instructions supported?
support
Please describe modbus rtu communication program instruction clearly.if possible, video example please.
we have rs485 example
for acceleration deceleration i tried setting m8144 M8145 for Y0 in all PLSY PLSV DRVI DRVA
does not seem to reponse. please help.
im stucked with using rs486. its not responding. can anyone help me tolve my prblem please.
thanks,
my whatsap is +9477***32548
please see our rs485 example.
Hello, does this PLC has self-diagnostic function? I have one L3U PLC in my hand now, and I need to test the self-diagnostic function.
no
Does this PLC has watchdog function?
no
I purchased the FX3U-48MR24 PLC. The communication cable did not come when purchased. I wanted to know what the pinout of that cable is so I can make one, since I can’t communicate with the FX3U. Note: I am using a ditect usb-rs232 converter but it does not communicate.

1. Hi, how to install GX simulator 7.16 E, since nothing happens when installed?
2. How to activate the function start ladder logic test (for simulation) on GX-Developer 8.5?
please check your system
I need to connect plc Le3u with coolmay TK6070FH hmi, I tried many time but still can’t communicate both of them. Please kindly advice.
what cable do you use?
Hello, I’m programming a structured project in GXWorks2 in an LE3U PLC. I have two questions:
1. Is structured project mode fully supported? Or must I use simple project in ladder.
2. I want to compare floating point numbers with “GT” or “>” function, but I can’t get it working. Do you have some advice?
Thanks!
it just support ladder.
Ola, essa clp tem a função PWM?

I can’t download (connect) new program ( PLC LE3U-14T 3 months was off – old program is working ). System COM7 FT232R (FTDI) working properly set 38,4K 7E1 None (also same problem for other cable driver340) – Developer FXCPU 38,4K COM7 – connection test – but still error
what error code
Quais são os registradores D retentivos no FX3u 24mr? (que salvam o valor quando desligada a energia)
D0 to D511 do not hold by default, and D511 holds by default. So when programming, pay attention to the allocation of data addresses. If you need to keep the power off, try to choose the D area after D511.
Before D511, it needs to be set to the power-off hold range, after D511, it is not necessary to set the power-off hold
Could you make tutorial communication RS 485 LE3U PLC to Haiwell HMI?
