What is I/O mapping in FANUC initial setup?

• A. Assigning physical inputs and outputs to robot I/O points for control and sensing.
• B. Scheduling maintenance windows for I/O hardware.
• C. Adjusting the robot's color display for I/O events.
• D. Calculating tool orientation.

Answer: (A)

I/O mapping is the process of linking the robot controller’s inputs and outputs to the actual hardware signals in the cell. During initial setup you define which physical inputs correspond to the controller’s digital inputs (like a safety interlock, start button, or sensor) and which physical outputs correspond to the controller’s digital outputs (such as a gripper, valve, or alarm). This mapping makes the robot’s software refer to signals by logical names rather than hardware pins, so the program can reliably read external conditions and drive peripheral devices. Proper I/O mapping enables safe, coordinated operation—e.g., the program can pause when a safety interlock is triggered or energize a gripper when a part is detected. The other options are about maintenance scheduling, display settings, or tool calculations, which are not what I/O mapping covers.
