Fanuc Ladder Logic [Trusted 2027]

Example rung:

[COMPB F10 = 3] → R100.0 (M03 request bit) Then later: fanuc ladder logic

1. Read physical inputs (X) → Input image table 2. Receive F signals from CNC (F) 3. Execute ladder logic (top to bottom, left to right) 4. Write outputs (Y) → physical outputs 5. Send G signals to CNC 6. Run diagnostics & communications (I/O Link) → Repeat (cycle time typically 4-32 ms) Outputs do not update instantly. A coil set in rung 10 will not be seen by rung 5 in the same scan. Use this to your advantage (or debug unexpected behavior). Example rung: [COMPB F10 = 3] → R100
