• PLC Version 1 works normally

    The PCB has soldered the components, burned the FX3U program, downloaded the ladder diagram, and it works fine. The first version works normally.
    In the next version, I will add the Efinix T8 FPGA and the 10MHz optocoupler to allow it for motion control.

  • 10MHz isolated optocoupler board is ok

    Use the FPGA T8 generate the pulse of 1Hz, 5Hz, 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, 1MHz, 5MHz, 10MHz, The isolation optocoupler board can work normally

  • Efinix 8K Lut FPGA, M4+8K FPGA is ok

    The Efinix T8 micro board I designed has been working normally, I think it should be a super small FPGA core board
    I used T8 to generate 10 pulses, 1Hz, 5Hz, 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, 1MHz, 5MHz, 10MHz
    I'm using a 10Mbps optocoupler and I want it to be able to output up to 10MHz pulses. It seems that there is a small problem with the first version. The circuit has been changed and I'm ready to make the next board

  • CPU Board is coming back

    CPU Board is coming back, The next step is SMT

  • New version pcb come back

    The newest version of the plc io pcb is comming,  i used a 10Mbps optocoupler for all 16x input channel and 16x output channel.

    The next plc cpu board version will change to use a M.Key NGFF type  core board,  the cpu is 240MHz Cortex M4 and connect a 1K Lut FPGA

    1. PLC 485 interface A,B signal is resevered with the display screen, open the PLC, exchange the A,B signal on the DB9
    2. Configured the FX3U  PLC according to Modbus Slave communication setting format
    3. Writes  AWTK GUI and Modbus communication code
    4. Test the screen and plc
    After finishing the above 4 steps, after a period of continuous electrical testing, Can initially use this control system for real applications
