  1. 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

  2. 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 [email protected]. thanks so much.

  7. 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.

  11. for acceleration deceleration i tried setting m8144 M8145 for Y0 in all PLSY PLSV DRVI DRVA
    does not seem to reponse. please help.

  12. im stucked with using rs486. its not responding. can anyone help me tolve my prblem please.
    thanks,
    my whatsap is +9477***32548

  13. 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.

  15. 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.

  16. 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?

  17. 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.

  18. 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!

  20. 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

    • 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
