The Zen of Ladder

The scan cycle is fast.

Rungs giveth power and taketh away.

And order has meaning.

But use order side effects sparingly.

One coil, one rung.

Latch only when needed.

If you need a FOR loop… no you don't.

Don't forget safety.

Keep it simple.

Test it.

Use clear tags and comments.

Name the purpose, not the part… unless you need a map to find it.

PackML and state machines are a honking great idea — let's use more of those.

ST is "street" abbreviated, right?

The tech (maybe you) at 3am will thank you.
