the only reason for me to use PLC way of programming is that it is something i fully understand
Limiting what you do to what you already know is a bad idea, learn new things.
If you insist on programming the Arduino in Ladder logic then what you should look for is something that pre-processses ladder logic into C code.
Somebody seems to have done this here;
However even if you were going to use something like this I would suggest you need to learn how to program the Arduino fully in C first, otherwise what is happening will just be "magic" and you will not really know what is going on.
