Asking questions
Get straight answers about your logic — with the rungs to back them up.
PLCchat answers questions about the project you've imported. Not the internet, not generic PLC trivia — your logic, the file you gave it.
Ask in plain English
Open a project and type what you'd ask a coworker who knows the program:
What starts the main conveyor?Where is tag Motor_03_Run used?Why would R042 fault on a cold start?List every rung that writes to Tank_Level_SP.
You don't need exact tag names or rung numbers. If you've got them, great — the answer gets sharper. If you don't, describe the machine and PLCchat will find them.
Every answer cites its rungs
This is the part that matters on the floor: PLCchat shows the exact rungs behind every answer. Click a citation to jump straight to that rung. If it can't find support in your logic, it says so instead of guessing.
Think of PLCchat as a fast pair of eyes on a program you already trust — not an oracle. You stay in control; it does the typing and the digging.
When answers go stale
PLCchat reads the version you imported. If the program on the controller has moved on, re-import the current L5X so its answers match what's actually running.
