Turning Your Raspberry Pi Pico to Mitsubishi FX1N PLC 

Glad it helped!

I finished what I wanted to build with this. I didn't use the optocoupler isolation board due to size constraints, and had flickering inputs. To get around this, each input pin that I used had a 750k ohm resistor to ground to get it to work. Once again, thanks for the explanation @@OnosTech

@boxcarhobo8315 My pleasure

I am glad it is helpful

Many thanks, will do!

Wooooow! 😲😲😲 Awesome!

Many thanks

Do you know if RPI Pico setup with this FW has all the instruction sets of FX1N typical Mitsibishi clone PLC??

Thanks 😊😊😊

Great information! Thanks for sharing.

Thank you for the firmware.

PLCs are basically industrial controllers that can easily be maintained (control logic & hardware) by technicians. You can get more detailed answers from Google search.

The outputs are available on the underside of the board except for GPO16 that is used for RGB LED

OK

Thanks! Display with PLCs like this is mainly possible with Modbus HMI. You can modify these FLProg ones for Outseal PLC to work with the Raspberry Pi Pico PLC. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g0OqOib9Lag.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zazJyEX599Y.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YmOSvV9BHfQ.html or use the OP320 HMI ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iC2vYqDj54s.html

Can use RS485 directly? 2:01

You can with Modbus

I use a serial to rs485 converter. Conv. Tx --- rx pico Conv. Rx--- tx pico In Gx Works i use D8121 address. H4081 move to D8121. 9600 8 None 1 In modbus poll show time error. But i test another Outseal Porgramme it response ok.

modbus program video please

Thanks

You are welcome

I am glad you like it. Pico W should also work.

Thanks a ton

Thanks
