I would like to know how to connect an arduino to PLC mitsubishi with RS-232 signal.
And would like to know how to write code arduino to convert signal into PLC
Or is there any way to study?
Provide links to the communications interface(s) and programming documentation for the exact model of PLC that you have.
Hi,

Can you tell us your electronics, programming, arduino, hardware experience?
What is the application, what data do you want to send/receive from/to PLC?
Thanks.. Tom...
