On an Arduino? What have you been smoking?

Compilers (and/or pre-compilers) exist for doing the programming in relay logic. The ones I played with are "pre-compilers" that generate C code that can then be opened in the Arduino IDE and compiled and downloaded to the Arduino.

As for what the OP wants, I haven't a clue. Likely the answer lies at the website from which they get the compiler. Because it certainly isn't going to be (well) supported here.
